5. First Usage – Quick Start
5.1 Connectors – Controls – Display
The front of the Fireface UFX II features four combined instrument / microphone inputs, two
stereo headphone outputs, three rotary encoders with push functionality, a graphical colour
display, one MIDI input and output, a USB connector for DURec, and several status LEDs.
The Neutrik combo sockets of the four
Mic/Line inputs provide XLR and 6.3 mm /
1/4" TRS connection. They have LEDs for
Signal (SIG), phantom power (48V) and
activated TRS input. The latter is high
impedance (1 MOhm) and also serves as
instrument input.
The analog outputs 9 to 12 feed the headphones outputs Phones 1 and Phones 2. These low
impedance outputs of highest quality are able to drive headphones at higher levels undistorted,
no matter if low or high impedance headphones are used.
MIDI 2 I/O. Two 5-pin DIN connectors provide the second MIDI input and output.
Memory. Connector for USB stick or USB hard drive. Offers direct recording to / playback from
the external memory device.
State LEDs Sync. WC, AES, ADAT1, ADAT2, CC. Indicate a valid input signal separately for
each digital input. Additionally, RME's exclusive SyncCheck indicates if one of these inputs is
locked, but not synchronous to the others, in which case the LED will flash. See also chapter
8.7 / 14.2, Clock Modes - Synchronization. The LED CC indicates Class Compliant operation.
State LEDs MIDI. Indicate separately for input and output if MIDI data is received or transmitted. HOST lights up when the connection to the computer is successful. Thunderbolt, USB 3
and USB 2 are indicated by different colours. The LED will not turn on when connection has not
been initialised or interrupted (error, cable not connected etc.).
When the Global Level Meter screen is shown, the rotary encoder Volume sets the monitoring
volume of Main Out directly at the device. Pushing the button will change between Global Meter
screen and the last used menu entry.
When the Global Level Meter screen is shown, volume of Phones 1 and Phones 2 is set by
encoders 1 and 2 directly.
The four keys, the two encoders 1
and 2, the high-resolution and clear
colour display, and a well thoughtout menu structure enable the user
to quickly change and configure the
device’s settings completely without
a computer. Help notes and clear
markers in the display guide the
user through all functions.

The rear panel of the Fireface UFX II features eight more analog inputs and outputs, the power
socket, and all digital inputs and outputs:
Balanced Line Level Inputs. 8 balanced analog inputs via 6.3 mm stereo TRS connectors.
Balanced Line Level Outputs. 8 balanced analog outputs, six via 6.3 mm stereo TRS, two via
XLR.
AES/EBU I/O. XLR. The Fireface UFX II accepts the
commonly used digital audio formats, SPDIF as well as
AES/EBU.
Word Clock I/O. BNC. Can be set to be terminated with
75 Ohms internally via Settings dialog, Input Options
ADAT1 I/O. TOSLINK. Standard ADAT optical port, 8
channels.
ADAT2 I/O. TOSLINK. Standard ADAT optical port, 8 channels. Can also be used as optical
SPDIF input and output, if set up accordingly in the Settings dialog.
Remote. Connector for the optional Advanced Remote Control USB (ARC USB) when the
UFX+ is used in stand-alone and Class Compliant mode. This port can also be used alternatively to the connection of the ARC USB to the computer.
USB 2.0. USB socket for connection to the computer. Compatible to USB 3.0.
MIDI I/O 1. Two 5-pin DIN connectors provide the first MIDI input and output.
Hook. Secure any loose cable by feeding it through the hook first.
IEC receptacle for mains power
connection. The internal hi-performance
switch mode power supply operates in the
range of 100V to 240V AC at highest
power efficiency. It is short-circuit-proof,
has an integrated line filter, is fully
regulated against voltage fluctuations,
suppresses mains interference, and offers
hum-free operation.

5.2 Quick Start
After the driver installation (chapter 6 / 13) connect the TRS jacks or the XLR inputs with the
analog signal source. The input sensitivity of the rear inputs can be changed in TotalMix (Input
Channel Settings, LoGain / +4 dBu and Gain), assuring the highest signal to noise ratio will be
achieved. Also try to achieve an optimum input level by adjusting the source itself. Raise the
source’s output level until the peak level meters in TotalMix reach about –3 dB.
The signal level of the front inputs can also be optimized directly at the
Fireface. The key MIC/GAIN gives direct access to this setting, which is
then controlled by the encoders 1 and 2. A two-colour LED beside the
sockets signals overload by a colour change from green to red.
The digital outputs of the Fireface UFX II provide AES/EBU (SPDIF
compatible) and ADAT optical signals at the corresponding ports.
On the analog playback side (the DA side), a coarse adjustment of the
analog output level at the rear jacks is again available in TotalMix
(Output Channel Settings, Level), or the Channel Settings directly at
the device. The big Volume encoder controls the Main Out volume
(default: Analog 1/2).
The output signal of channels 9/10 and 11/12, Phones 1 and 2, can be
controlled directly from front by the small encoders 1 and 2.
The Fireface UFX II can store and load its current state in 6 different
memory slots, called Setups. With this, the Fireface UFX II can be
used stand-alone after setting it up accordingly, replacing lots of
dedicated devices (see chapter 24).
In online mode some settings are greyed out, as these should be changed only at the computer,
in the Settings dialog or in TotalMix FX. These include the choice of sample rate and the mix
settings.

6. Hardware, Driver and Firmware Installation
6.1 Hardware and Driver Installation
To simplify installation it is recommended to first install the drivers before the unit is connected
to the computer. But it will also work the other way round.
Insert the RME Driver CD into your CD-ROM drive. The driver installer is located in the directory
\MADIface_USB (NOT Fireface_USB)
Start rmeinstaller.exe and follow the instructions of the installer. After installation connect computer and UFX+ using a USB 2 cable. Windows detects the new hardware as Fireface UFX II
and installs the drivers automatically.
After a reboot, the icons of TotalMix FX and Settings dialog appear
in the notification area.
Driver Updates do not require to remove the existing drivers. Simply install the new driver over
the existing one.
6.2 De-Installing the Drivers
A de-installation of the driver files is not necessary – and not supported by Windows anyway.
Thanks to full Plug & Play support, the driver files will not be loaded after the hardware has
been removed. If desired these files can then be deleted manually.
Unfortunately Windows Plug & Play methods do not cover the additional autorun entries of TotalMix, the Settings dialog, and the registration of the ASIO driver. Those entries can be removed from the registry through a software de-installation request. This request can be found
(like all de-installation entries) in Control Panel, Software. Click on the entry 'RME MADIface'.
6.3 Firmware Update
The Flash Update Tool updates the firmware of the Fireface UFX II to the latest version. It requires an already installed driver.
Start the program fut_mfusb.exe. The Flash Update Tool displays the current revision of the
Fireface firmware, and whether it needs an update or not. If so, then simply press the 'Update'
button. A progress bar will indicate when the flash process is finished (Verify Ok).
After the update the unit needs to be reset. This is done by powering down the unit for a few
seconds. A reboot of the computer is not necessary.
When the update unexpectedly fails (status: failure), the unit's Safety BIOS will be used from
the next boot on, the unit stays fully functional. The flash process should then be tried again.
14
User's Guide Fireface UFX II © RME
7. Configuring the Fireface
7.1 Settings dialog – Main Tab
Configuration of the Fireface UFX II is done via its own settings dialog. The panel Settings can
be opened by clicking on the fire or hammer symbol in the Task Bar's system tray.
The mixer of the Fireface UFX II, TotalMix FX, can be opened by
clicking on the DSP FX symbol in the Task Bar's system tray
The hardware of the Fireface UFX II offers a number of helpful, well thought-of practical functions and options which affect how the card operates - it can be configured to suit many different requirements. The 'Settings' dialog includes options for:
•
•
•
•
•
•
Latency
Operation of the DSP
Configuration of the digital I/Os
Current sample rate
Synchronization behaviour
State of input and output
Any changes made in the Settings
dialog are applied immediately confirmation (e.g. by clicking on OK or
exiting the dialog) is not required.
However, settings should not be
changed during playback or record if it
can be avoided, as this can cause
unwanted noises. Also, please note
that even in 'Stop' mode, several programs keep the recording and playback
devices open, which means that any
new settings might not be applied
immediately.
The tab About includes information
about the current driver and firmware
version of the Fireface, and three more
options:
Lock Registry
Default: off. Checking this option brings
up a dialog to enter a password.
Changes in the Settings dialog are no
longer written to the registry. As the
settings are always loaded from the
registry when starting the computer, this method provides an easy way to define an initial state
of the Fireface UFX II.
Enable MMCSS for ASIO activates support with higher priority for the ASIO driver. Note: At this
time, activating this option seems to be useful only with the latest Cubase/Nuendo at higher
load. With other software this option can decrease performance. The change becomes active
after an ASIO reset. Therefore it is easy to quickly check which setting works better.
The third option, Limit ASIO to 32 channels, is not valid for the UFX II.
User's Guide Fireface UFX II © RME
15
Buffer Size
The setting Buffer Size determines the latency between incoming and outgoing ASIO and WDM
data, as well as affecting system stability (see chapter 9.1).
USB Diagnosis indicates USB transmission errors. The display will be reset on any start of a
playback/record. More information can be found in chapter 39.3.
Input Options
Word Clock In Termination
Checking this option terminates the word clock input internally with 75 Ohms.
Optical 2 In
Operates as second ADAT input (default). Selecting AES/SPDIF will route the optical input signal to the AES-Receiver. This mode disables the AES input via XLR.
EQ+D for Record
Switches EQ and Dynamics of all input channels into the recording path. In case Loopback has
been activated the EQ and Dynamics of the Output channel are within the recording path. See
also chapter 27.6.
TMS activates the transmission of Channel Status data and Track Marker information on AES
and SPDIF inputs. In case these information are not required the feature should be turned off.
Output Options
AES Format
The AES output signal can have the Channel Status Professional or Consumer (SPDIF). This
setting is also valid when ADAT2 has been set as AES/SPDIF output. For further details please
refer to chapter 21.2.
Optical 2 Out
This optical TOSLINK output can operate as ADAT or AES/SPDIF output.
WDM Devices
Allows to freely set which I/Os are available as WDM devices, if these are stereo or multichannel devices (up to 8 channels), and if one or multiple of the currently active WDM devices
should have the Speaker property. More details are found in chapter 7.2.
16
User's Guide Fireface UFX II © RME
Clock Mode
Word Clock – Single Speed
The word clock output signal usually equals the current sample rate. Selecting Single Speed
causes the output signal to always stay within the range of 32 kHz to 48 kHz. So at 96 kHz and
192 kHz sample rate, the output word clock is 48 kHz.
Sample Rate
Sets the currently used sample rate.
Offers a central and comfortable way of
configuring the sample rate of all WDM
devices to the same value, as since
Vista the audio software is no longer
allowed to set the sample rate.
However, an ASIO program can still set
the sample rate by itself.
During record/playback the selection is
greyed out, so no change is possible.
Clock Source
The unit can be configured to use its
own clock (Internal = Master), or one of
the input signals (Word, AES, ADAT1,
ADAT2). If the selected source isn't
available (Input Status No Lock), the
unit will change to the next available
one (AutoSync). If none is available
then the internal clock is used. The
current clock source is displayed to the
right.
Input Status
Indicates for each input (Word, AES,
ADAT1, ADAT2) whether there is a
valid signal (Lock, No Lock), or if there
is a valid and synchronous signal
(Sync). The third column shows the
sample frequency detected by the hardware (coarse recognition, 32 kHz, 44.1
kHz, 48 kHz etc.).
User's Guide Fireface UFX II © RME
17
7.2 Option WDM Devices
The WDM Devices configuration has one button to enter the edit dialog, a status display showing the number of currently enabled WDM devices, and a listbox to change between Stereo or
Multi-Channel devices.
The number represents both record and
playback devices, so ‘1’ means one input
and one output device.
The screenshot to the right shows the
stereo WDM devices available with the UFX
II, and that only Analog 1/2 has been
activated. Any number can be activated.
Also only higher numbered devices might
be active. For example using the ADAT
output 7/8 for system based audio does not
require to activate all ADAT devices in front.
Only ADAT 7/8 will show up in the Windows
Sound control panel.
The checkbox All to the right allows for a
quick check/uncheck of all devices.
Activating all 15 stereo devices at once
may cause temporary freezing or ‘not
responding’ effects. Therefore activate
only the ones which are really needed.
The screenshot to the left shows the multichannel WDM devices available with the
UFX II after selecting ‘Multi-Channel’ in the
WDM Devices listbox and hitting WDM
Configure. In this example the devices
Analog 1 to 8 and ADAT 1 to 8 are active.
Using a multi-channel WDM device allows
for the use of multi-channel playback with
specialized software as well as Surround
sound from DVD or Blu-Ray player software.
Please note that configuring the WDM
device to a specific surround mode in the
control panel Sound requires the device to
have the Speaker property. See next page.
Again the checkbox All to the right allows for
a quick check/uncheck of all devices.
18
User's Guide Fireface UFX II © RME
Changing to the tab Speaker presents a list
of all currently activated WDM devices. Any
of these can now get the Speaker property.
Please note that defining more than one
device as Speaker usually makes no
sense, and the speakers also don’t get
numbered or renamed in Windows, so it is
impossible to find out which one is which.
After leaving the dialog with OK the WDM
devices are reloaded so Windows sees
their new properties. You can now assign
any surround mode, from stereo to 7.1, in
the Windows Sound control panel by
selecting the playback device and clicking
the Configure button.
User's Guide Fireface UFX II © RME
19
8. Operation and Usage
8.1 Playback
The Fireface UFX II can play back audio data in supported formats only (sample rate, bit resolution). Otherwise an error message appears (for example at 22 kHz and 8 bit).
In the audio application being used, Fireface must be selected as output device. This can often
be found in the Options, Preferences or Settings menus under Playback Device, Audio Devices,
Audio etc.
We recommend switching all system sounds off (via >Control Panel /Sounds<). Although the
Fireface UFX II comes with extensive support for system audio, setting it to be the Default Device for playback could cause problems when working with ASIO.
The screenshot shows a typical configuration dialog of a (stereo) wave editor. Audio data is
sent to an analog or digital port, depending on which has been selected as playback device.
Increasing the number and/or size of audio buffers may prevent the audio signal from breaking
up, but also increases latency i.e. output is delayed. For synchronized playback of audio and
MIDI (or similar), be sure to activate the checkbox ‘Get position from audio driver’.
Note: Since Vista the audio application can no longer control the sample rate under WDM.
Therefore the driver of the Fireface UFX II includes a way to set the sample rate globally for all

8.2 DVD-Playback (AC-3/DTS)
AC-3 / DTS
When using popular DVD software players, their audio data stream can be sent to any AC3/DTS capable receiver via the Fireface UFX II.
!
The sample rate must be set to 48 kHz in the UFX II Settings dialog, or the software will
only playback the down-mixed analog signal via SPDIF.
In some cases an UFX II output device has to be selected in >Control Panel / Sound / Playback< and be set as Default, or the software will not recognize it.
The DVD software's audio properties now show the options 'SPDIF Out' or similar. When selecting it, the software will transfer the non-decoded digital multichannel data stream to the Fireface.
Note: This 'SPDIF' signal sounds like chopped noise at highest level. Try to avoid mixing and
routing the signal to your loudspeakers, as they might get damaged.
Multichannel
PowerDVD and WinDVD can also operate as software decoder, sending a DVD's multichannel
data stream directly to the analog outputs of the Fireface. For this to work select the WDM playback device ’Loudspeaker’ of the Fireface in >Control Panel/ Sound/ Playback < as Default.
Additionally the loudspeaker setup, found under Configuration, has to be changed from Stereo
to 5.1 Surround.
PowerDVD's and WinDVD's audio properties now list several multichannel modes. If one of
these is selected, the software sends the decoded analog multichannel data to the Fireface.
TotalMix can then be used to play back via any desired output channels.
The typical channel assignment for surround playback is:
1 - Left
2 - Right
3 - Center
4 - LFE (Low Frequency Effects)
5 - SL (Surround Left)
6 - SR (Surround Right)
Note 1: Selecting the Fireface to be used as system playback device is against our recommendation, as professional interfaces should not be disturbed by system events. Make sure to reassign the selection after usage or to disable any system sounds (tab Sounds, scheme 'No
audio').
Note 2: The DVD player will be synced backwards from the Fireface. This means when using
AutoSync and/or word clock, the playback speed and pitch follows the incoming clock signal.

8.3 Channel Count under WDM
The Fireface ADAT optical ports allow to record sample rates of up to 192 kHz using a standard
ADAT recorder. For this to work single-channel data is spread to two or four ADAT channels
using the Sample Multiplexing technique. This reduces the number of available ADAT channels
from 8 to 4 or 2 per ADAT port.
Whenever the Fireface changes into Double Speed (88.2/96 kHz) or Quad Speed mode
(176.4/192 kHz) all devices no longer available vanish automatically.

8.4 Multi-client Operation
RME audio interfaces support multi-client operation. Several programs can be used at the same
time. The formats ASIO and WDM can even be used on the same playback channels simultaneously. But as WDM uses a real-time sample rate conversion (ASIO does not), all active ASIO
software has to use the same sample rate.
However, a better overview is maintained by using the channels exclusively. This is no limitation
at all, because TotalMix allows for any output routing, and therefore a playback of multiple software on the same hardware outputs.
Inputs can be used from an unlimited number of WDM and ASIO software at the same time, as
the driver simply sends the data to all applications simultaneously.
RME's sophisticated tool DIGICheck is an exception to this rule. It operates like an ASIO host,
using a special technique to access playback channels directly. Therefore DIGICheck is able to
analyse and display playback data from any software, no matter which format it uses.

8.5 Analog Recording
For recordings via the analog inputs the corresponding record device has to be chosen (Fireface UFX II Analog (x+x)).
The input sensitivity of the rear inputs can be changed in two steps and with adjustable gain in
TotalMix (Input Channel Settings, Level), assuring the highest signal to noise ratio will be
achieved. A further optimization can be achieved by adjusting the source itself. Raise the
source’s output level until the peak level meters in TotalMix reach about –3 dB.
The level of the front-side analog inputs can be optimized via TotalMix (Input Channel Settings,
Gain), or directly at the Fireface UFX II by the key Mic/Gain and the encoders 1/2. A double
coloured signal and clip LED provides useful information about the current level state.
Further information is found in chapter 19.
It often makes sense to monitor the input signal or send it directly to the output. This can be
done at zero latency using TotalMix FX (see chapter 25).
An automated control of real-time monitoring can be achieved by Steinberg’s ASIO protocol
with RME’s ASIO drivers and all ASIO 2.0 compatible programs. When 'ASIO Direct Monitoring'
has been switched on, the input signal is routed in real-time to the output whenever a recording
is started (punch-in).
8.6 Digital Recording
Unlike analog soundcards which produce empty wave files (or noise) when no input signal is
present, digital interfaces always need a valid input signal to start recording.
Taking this into account, RME added a
comprehensive I/O signal status display to the
Fireface UFX II, showing sample frequency, lock
and sync status for every input, and several status
LEDs directly at the unit.
The sample frequency shown in the fields Clock
Mode and Input Status is useful as a quick display
of the current configuration of the unit and the
connected external equipment. If no sample frequency is recognized, it will read ‘No Lock’.
This way, configuring any suitable audio application for digital recording is simple. After selecting the correct input, Fireface UFX II displays the current sample frequency. This parameter can
then be changed in the application’s audio attributes (or similar) dialog.

8.7 Clock Modes - Synchronization
In the digital world, all devices must be either Master (clock source) or Slave (clock receiver).
Whenever several devices are linked within a system, there must always be a single master
clock.
!
A digital system can only have one master! If the Fireface’s clock mode is set to 'Master', all
other devices must be set to ‘Slave’.
The Fireface UFX II utilizes a very user-friendly, intelligent clock control, called AutoSync. In
AutoSync mode, the system constantly scans the digital input for a valid signal. If any valid signal is found, the Fireface switches from the internal quartz (Clock Mode – Current Internal) to a
clock extracted from the input signal (Clock Mode – Current ADAT, AES or Word). The difference to a usual slave mode is that whenever the clock reference fails, the system will automatically use its internal clock and operate in clock mode Master.
AutoSync guarantees that record and record-while-play will always work correctly. In certain
cases however, AutoSync may cause feedback in the digital carrier, so synchronization breaks
down. To remedy this, switch the Fireface clock mode to ‘Internal’.
RME’s exclusive SyncCheck technology enables an easy to use check and display of the current clock status. SyncCheck indicates whether there is a valid signal (Lock, No Lock) for each
input (Word Clock, ADAT, AES), or if there is a valid and synchronous signal (Sync). See chapter 39.1.
Via Clock Source a preferred input can be defined. As long as the Fireface sees a valid signal
there, this input will be designated as the sync source, otherwise the other inputs will be
scanned in turn. If none of the inputs are receiving a valid signal, the Fireface automatically
switches clock mode to ‘Internal’.
Under WDM the Fireface will (has to) set the
sample rate. Therefore the error shown to the
right can occur. An AES, SPDIF or ADAT
signal with a sample rate of 48 kHz is used as sync source, but Windows audio had been set to
44100 Hz before. The red color of the text label signals the error condition, and prompts the
user to set 48000 Hz manually as sample rate.
Under ASIO the audio software sets the sample rate, so that such an error will usually not happen – but it can too. In slave mode the external sample rate has priority. Feeding 44.1 kHz will
prevent the ASIO software to set 48 kHz – obviously, as the only way to do so would be to enter
a different clock mode (Master/Internal).
In practice, SyncCheck provides the user with an easy way of checking whether all digital devices connected to the system are properly configured. With SyncCheck, finally anyone can
master this common source of error, previously one of the most complex issues in the digital
studio world.

9. Operation under ASIO
9.1 General
Start the ASIO software and select ASIO MADIface USB as the audio I/O device or the ASIO
audio driver.
The Fireface UFX II supports ASIO Direct Monitoring (ADM).
The Fireface UFX II MIDI I/Os can be used with both MME MIDI and DirectMusic MIDI.
9.2 Channel Count under ASIO
At a sample rate of 88.2 or 96 kHz, the ADAT optical input and outputs operate in S/MUX mode,
so the number of available channels per port is reduced from 8 to 4. At a sample rate of 176.4
and 192 kHz, the ADAT optical input and output operates in S/MUX4 mode, so the number of
available channels is limited to 2.
Note: When changing the sample rate range between Single, Double and Quad Speed the
number of channels presented from the ASIO driver will change too. This may require a reset of
the I/O list in the audio software.
Single Speed
Fireface Analog 1 to 12
Fireface AES L / R
Fireface ADAT 1 to 16
Double Speed
Fireface Analog 1 to 12
Fireface AES L / R
Fireface ADAT 1 to 8
Quad Speed

9.3 Known Problems
If a computer does not provide sufficient CPU-power, and/or sufficient USB or PCI bus transfer
rates, and/or sufficient PCIe-bus transfer rates, then drop outs, crackling and noise will appear.
Raising the buffer size in the Settings dialog of the Fireface UFX II helps in most cases. It is
also recommended to deactivate all PlugIns to verify that these are not the reason for such effects. Further information is found in chapter 39.3.
Another common source of trouble is incorrect synchronization. ASIO does not support asynchronous operation, which means that the input and output signals not only have to use the
same sample frequency, but also have to be in sync. All devices connected to the Fireface UFX
II must be properly configured for full duplex operation. As long as SyncCheck (in the Settings
dialog) only displays Lock instead of Sync, the devices have not been set up properly.
The same applies when using more than one Fireface UFX II - they all have to be in sync. Else
a periodically repeated noise will be heard.
RME devices support ASIO Direct Monitoring (ADM). Please note that not all programs support
ADM completely or error-free. The most often reported problem is the wrong behaviour of panorama in a stereo channel. Also try to avoid setting the TotalMix FX hardware outputs (third row)
to mono mode. This will most likely break ADM compatibility.
In case of a drift between audio and MIDI, or in case of a fixed deviation (MIDI notes placed
close before or behind the correct position), the settings in Cubase/Nuendo have to be
changed. At the time of print the option 'Use System Timestamp' should be activated. The Fireface UFX II supports both MME MIDI and DirectMusic MIDI. It depends on the used application
which one will work better.
10. Using more than one Fireface UFX II
The driver supports up to three Fireface UFX II or a combination of up to three supported interfaces. All units have to be in sync, i.e. have to receive valid sync information (either via word
clock or by using AutoSync and feeding synchronized signals).
•
If one of the Firefaces is set to clock mode Master, all others have to be set to clock mode
AutoSync, and have to be synced from the master, for example by feeding word clock. The
clock modes of all units have to be set up correctly in the Fireface Settings dialog.
•
If all units are fed with a synchronous clock, i.e. all units show Sync in their Settings dialog,
all channels can be used at once. This is especially easy to handle under ASIO, as the
ASIO driver presents all units as one.
Please be aware that operating more than one Fireface UFX II may cause resource problems
on the computer side.
Note: TotalMix is part of the hardware of each Fireface. Up to three mixers are available, but
these are separated and can't interchange data. Therefore a global mixer for all units is not
possible.

The second port ADAT channels don’t seem to work
• The optical output ADAT2 has been switched to AES/SPDIF. As can be seen in the block
diagram, all channels and their assignments still exist, but the optical transmitter has been
disconnected from ADAT2 and is now fed from the AES output (channels 13/14). The
ADAT2 playback devices are still usable by routing and mixing them in TotalMix to other outputs.
Playback works, but record doesn’t
• Check that there is a valid signal at the input. If so, the current sample frequency is displayed in the Settings dialog.
• Check whether the Fireface UFX II has been selected as recording device in the audio application.
• Check whether the sample frequency set in the audio application (‘Recording properties’ or
similar) matches the input signal.
• Check that cables/devices have not been connected in a closed loop. If so, set the system’s
clock mode to Master.
Crackle during record or playback
• Increase the number and size of buffers in the ‘Settings’ dialog or in the application.
• Try different cables (coaxial or optical) to rule out any defects here.
• Check that cables/devices have not been connected in a closed loop. If so, set the system’s
clock mode to ‘Master’.
• Check the Settings dialog for displayed Errors.
Driver installation and Settings dialog/TotalMix work, but a playback or record is not possible

While recognition and control of the device are low bandwidth applications, playback/record
needs the full transmission performance. Therefore, defective USB cables with limited
transmission bandwidth can cause such an error scheme.

13. Hardware, Driver and Firmware Installation
13.1 Hardware and Driver Installation
After the Fireface has been connected to the computer and switched on install the drivers from
the RME Driver CD. The driver files are located in the folder \MADIface_USB. Installation works
automatically by a double-click on the file Fireface USB.pkg.
A special driver for the latest macOS Sierra is also available (currently version 3.01)
RME recommends downloading the latest driver version from the RME website. If done, the
procedure is as follows:
A double-click onto driver_usb_mac.zip expands the archive file to Fireface USB.pkg. Installation works automatically by a double-click on this file.
During driver installation the programs Totalmix (TotalMix FX) and Fireface USB Settings are
copied to the Applications folder. They will automatically start into the dock if a Fireface UFX II
is connected. A reboot of the computer is not required.
Driver Updates do not require to remove the existing drivers. Simply install the new driver over
the existing one.
13.2 De-installing the Drivers
In case of problems the driver files can be deleted manually by dragging them to the trash bin:
USB
/Applications/Fireface USB Settings
/Applications/Totalmix
/Library/Extensions/FirefaceUSB.kext
/Users/username/Library/Preferences/de.rme-audio.TotalmixFX.plist
/Users/username/Library/Preferences/de.rme-audio.Fireface_USB_Settings.plist
/Library/LaunchAgents/de.rme-audio.firefaceUSBAgent.plist
Under the latest Mac OS the User/Library folder is not visible in the Finder. To unhide it start
Finder, click on the menu item Go. Hold down the option (alt) key, then click on Library.
13.3 Firmware Update
The Flash Update Tool updates the firmware of the Fireface UFX II to the latest version. It requires an already installed Thunderbolt or USB driver.
Start the program Fireface USB Flash. The Flash Update Tool displays the current revision of
the UFX+ firmware, and whether it needs an update or not. If so, simply press the 'Update' button. A progress bar will indicate when the flash process is finished (Verify Ok).
After the update the Fireface UFX II needs to be reset. This is done by powering down the Fireface for a few seconds. A reboot of the computer is not necessary.
When the update fails (status: failure), the unit's second BIOS will be used from the next cold
boot on (Secure BIOS Technology). Therefore the unit stays fully functional. The flash process
should then be tried again on a different computer.

14. Configuring the Fireface UFX II
14.1 Settings Dialog
Configuring the Fireface is done via its own settings dialog. Start the program Fireface USB
Settings. The mixer of the Fireface UFX II (TotalMix FX) can be configured by starting the program Totalmix.
The Fireface’s hardware offers a number of helpful, well thought-out practical functions and
options which affect how the card operates - it can be configured to suit many different requirements. The following is available in the 'Settings' dialog:
•
•
•
•
•
Operation of the DSP
Configuration of digital I/Os
Current sample rate
Synchronization behaviour
State of input and output
Any changes performed in the
Settings dialog are applied
immediately - confirmation (e.g. by
exiting the dialog) is not required.
However, settings should not be
changed during playback or
record if it can be avoided, as this
can cause unwanted noises.
Use the drop down menu
Properties For to select the unit
to be configured.
On the right of it the current
firmware and driver version is
shown.
Input Options
Word Clock - Termination
Checking this option terminates
the word clock input internally with
75 Ohms.
Optical 2 In
SPDIF will turn the optical input into an optical SPDIF input, ADAT into an ADAT input (default).
Please note that using the optical input with SPDIF disables the AES input via XLR.
DSP – Record EQ+D
Switches EQ and Dynamics of all input channels into the recording path. In case Loopback has
been activated the EQ and Dynamics of the Output channel are within the recording path. See
also chapter 27.6.
User's Guide Fireface UFX II © RME

Output Options
AES Format
The AES output signal can have the Channel Status Professional or Consumer (SPDIF). This
setting is also valid when ADAT2 has been set as AES/SPDIF output. For further details please
refer to chapter 21.2.
Optical 2 Out
This optical TOSLINK output can operate as ADAT or SPDIF output.
Clock Options
Word Clock I/O – Single Speed
The word clock output signal usually equals the current sample rate. Selecting Single Speed
causes the output signal to always stay within the range of 32 kHz to 48 kHz. So at 96 kHz and
192 kHz sample rate, the output word clock is 48 kHz.
The word clock input usually adapts to the current sample rate range. For example a 48 kHz
word signal can be used to sync the internal clock of 96 and 192 kHz. When the option Single
Speed is active the interface’s sample rate follows the external sample rate even over Single,
Double and Quad Speed. A word signal of 192 kHz will cause the UFX+ to use 192 kHz internally. This feature is also called Follow Clock.
Sample Rate
Used to set the current sample rate. This is the same setting as in the Audio MIDI Setup, just
added here for your convenience.
Clock Source
The unit can be configured to use its own clock (Internal = Master), or one of the input signals
(Word, AES, ADAT1, ADAT2). If the selected source isn't available (Input Status No Lock), the
unit will change to the next available one (AutoSync). If none is available then the internal clock
is used. The current clock source is displayed below.
Input Status
Indicates for inputs Word, AES, ADAT1 and ADAT2 whether a valid signal (Lock, No Lock) or a
valid and synchronous signal (Sync) is present. The third column shows the sample frequency
detected by the hardware (coarse recognition, 32 kHz, 44.1 kHz, 48 kHz etc.).

14.2 Clock Modes - Synchronization
In the digital world, all devices must be either Master (clock source) or Slave (clock receiver).
Whenever several devices are linked in a system, there must always be a single master clock.
!
A digital system can only have one master! If the Fireface’s clock mode is set to 'Master', all
other devices must be set to ‘Slave’.
The Fireface UFX II utilizes a very user-friendly, intelligent clock control, called AutoSync. In
AutoSync mode, the system constantly scans the digital input for a valid signal. If any valid signal is found, the Fireface switches from the internal quartz (Clock Mode – Current Internal) to a

AutoSync guarantees that record and record-while-play will always work correctly. In certain
cases however, AutoSync may cause feedback in the digital carrier, so synchronization breaks

RME’s exclusive SyncCheck technology enables an easy to use check and display of the current clock status. SyncCheck indicates whether there is a valid signal (Lock, No Lock) for each
input (Word Clock, ADAT, AES), or if there is a valid and synchronous signal (Sync). In the field
Clock Mode the clock reference is shown. See chapter 39.1.
Via Clock Source a preferred input can be defined. As long as the Fireface sees a valid signal
there, this input will be designated as the sync source, otherwise the other inputs will be
scanned in turn. If none of the inputs are receiving a valid signal, the Fireface automatically
switches clock mode to ‘Internal’.
In some situations changing the clock mode can not be
avoided. Example: An ADAT recorder is connected to
the ADAT input (ADAT immediately becomes the
AutoSync source) and a CD player is connected to the
AES input. Try recording a few samples from the CD
and you will be disappointed - few CD players can be
synchronized. The samples will inevitably be corrupted, because the signal from the CD player is read
with the clock from the ADAT. In this case the Clock
Source should be temporarily set to AES.
In practice, SyncCheck provides the user with an easy way of checking whether all digital devices connected to the system are properly configured. With SyncCheck, finally anyone can
master this common source of error, previously one of the most complex issues in the digital
studio world.

15. Mac OS X FAQ
15.1 MIDI doesn't work
In some cases the applications do not show the MIDI port. The reason for this is usually visible
within the Audio MIDI Setup. It displays no RME MIDI device, or the device is greyed out and
therefore inactive. Mostly, removing the greyed out device and searching for MIDI devices again
will solve the problem.
The Fireface’ MIDI is class compliant. Therefore it comes without a driver. OS X recognizes it
as MIDI device and will be using it with the driver included in the operating system.
15.2 Repairing Disk Permissions
Repairing permission can solve problems with the installation process - plus many others. To do
this, launch Disk Utility located in Utilities. Select your system drive in the drive/volume list to
the left. The First Aid tab to the right now allows you to check and repair disk permissions.
15.3 Supported Sample Rates
RME's Mac OS X driver supports all sampling frequencies provided by the hardware. This includes 32 kHz and 64 kHz, and even 128 kHz, 176.4 kHz and 192 kHz.
But not any software will support all the hardware's sample rates. The hardware's capabilities
can easily be verified in the Audio MIDI Setup. Select Audio devices under Properties of:
and choose the Fireface. A click on Format will list the supported sample frequencies.
15.4 Channel Count under Core Audio
At a sample rate of 88.2 or 96 kHz, the ADAT optical input and outputs operate in S/MUX mode,
so the number of available channels per port is reduced from 8 to 4. At a sample rate of 176.4
and 192 kHz, the ADAT optical input and output operates in S/MUX4 mode, so the number of
available channels is limited to 2.
It is not possible to change the number of Core Audio channels without a reboot of the computer. Therefore whenever the Fireface changes into Double Speed (88.2/96 kHz) or Quad
Speed mode (176.4/192 kHz) all channels stay present, but become partly inactive.

15.5 Various Information
The driver of the Fireface UFX II requires at least Mac OS 10.6.
Programs that don't support card or channel selection will use the device chosen as Input and
Output in the System Preferences – Sound panel.
Via Launchpad – Other – Audio MIDI Setup the Fireface can be configured for the system
wide usage in more detail.
Programs that don't support channel selection will always use channels 1/2, the first stereo pair.
To access other inputs, use the following workaround with TotalMix: route the desired input
signal to output channels 1/2. In the channel settings of outputs 1/2 activate Loopback. Result:
the desired input signal is now available at input channel 1/2, without further delay/latency.
Use Configure Speakers to freely configure the stereo or multichannel playback to any available channels.
16. Using more than one Fireface
OS X supports the usage of more than one audio device within an audio software. This is done
via the Core Audio function Aggregate Devices, which allows to combine several devices into
one.
The current driver supports up to three Fireface UFX II. All units have to be in sync, i.e. have to
receive valid sync information either via word clock or by feeding synchronized signals.
•
If one of the Firefaces is set to clock mode Master, all others have to be set to clock mode
Slave, and have to be synced from the master, for example by feeding word clock. The
clock modes of all units have to be set up correctly in the Fireface Settings dialog.
•
If all units are fed with a synchronous clock, i.e. all units show Sync in their Settings dialog,
all channels can be used at once.
Note: TotalMix is part of the Fireface hardware. Up to three mixers are available, but these are
separated and can't interchange data. Therefore a global mixer for all units is not possible.
Please be aware that operating more than one Fireface UFX II may cause resource problems
on the computer side.

18. Hotline – Troubleshooting
The newest information can always be found on our website www.rme-audio.com, section FAQ,
latest Additions.
The unit and drivers have been installed correctly, but playback does not work:
• Has Fireface been selected as current playback device in the audio application?
The 8 ADAT channels don’t seem to work
• The optical output ADAT2 has been switched to AES/SPDIF. As can be seen in the block
diagram, all channels and their assignments still exist, but the optical transmitter has been
disconnected from ADAT2 and is now fed from the AES output (channels 13/14). The
ADAT2 playback devices are still usable by routing and mixing them in TotalMix to other outputs.
Playback works, but record doesn’t:
• Check that there is a valid signal at the input. If so, the current sample frequency is displayed in the Settings dialog.
• Check whether the Fireface UFX II has been selected as recording device in the audio application.
• Check whether the sample frequency set in the audio application (‘Recording properties’ or
similar) matches the input signal.
• Check that cables/devices have not been connected in a closed loop. If so, set the system’s
clock mode to ‘Master’.
Crackle during record or playback:
• Increase the number and size of buffers in the application.
• Try different cables (coaxial or optical) to rule out any defects here.
• Check that cables/devices have not been connected in a closed loop. If so, set the system’s
clock mode to ‘Master’.
• Check the Settings dialog for displayed Errors.
Possible causes for a Fireface not working
• The USB cable is not, or not correctly inserted into the socket
Driver installation and Settings dialog/TotalMix work, but a playback or record is not possible
•
While recognition and control of the device are low bandwidth applications, playback/record
needs the full transmission performance. Therefore, defective USB cables with limited
transmission bandwidth can cause such an error scheme.

19. Analog Inputs
19.1 Line Rear
The Fireface has eight balanced Line inputs as 1/4" TRS jacks on the back of the unit. The electronic input stage is built in a servo balanced design which handles unbalanced (mono jacks)
and balanced (stereo jacks) correctly, automatically adjusting the level reference.
!
When using unbalanced cables with TRS jacks: be sure to connect the 'ring' contact of the
TRS jack to ground. Otherwise noise may occur, caused by the unconnected negative input
of the balanced input.
One of the main issues when working with an AD-converter is to maintain the full dynamic
range within the best operating level. Therefore the Fireface UFX II internally uses hi-quality
electronic switches, which allow for a perfect adaptation of all rear inputs individually to the most
often used studio levels. The Fireface UFX II offers the following level references:
Reference
Lo Gain
+4 dBu
0 dBFS @
+19 dBu
+13 dBu
Headroom
15 dB
9 dB
The above levels are also found in all other RME devices. Therefore they are fully compatible to
each other. A reference level of -10 dBV can be set by using +4 dBu and adding 9 dB of gain
with the Gain knob in the TotalMix FX channel settings.
19.2 Microphone / Line / Inst Front
The four balanced microphone inputs of the Fireface UFX II offer a digitally controlled gain of 0
to 75 dB via XLR/TRS combo jacks. The gain range is 75 dB for XLR, adjustable in 1 dB-steps
from 8 to 75 dB, and 0 dB as additional step. The soft switching, hi-current Phantom power (48
Volt), switchable per channel, provides a professional handling of condensor mics. Up to a level
of +18 dBu, the front XLR input can also be used as Line input.
The unbalanced TRS Line inputs (R is connected to ground), which can be used alternatively,
add even greater flexibility to the Fireface UFX II. With 1 MOhm input impedance (Hi-Z), TS jack
and adjustable input gain from +8 dB to +50 dB, the front-side inputs can be used perfectly with
keyboards, sampler, CD player, guitars and many more. They handle levels from -21 dBu up to
+21 dBu, turning them into full level Line inputs. Thus the unit can also be used as Line gain
amplifier.
The TRS jacks are free of phantom power.
A two colour LED display a present signal (green, from –60 dBFS) and warns against overload
(0 dBFS).
Channels 9 to 12 feature an automatic overload protection. AutoSet tries to keep a headroom
of 6 dB. Levels higher than -6 dBFS will permanently reduce the gain. To check set the channels to a high gain and apply an input signal. The button will quickly rotate back to a gain that is
appropriate. While AutoSet in the UFX+ is not exactly the same as in the RME Micstasy (with
extreme overloads distortion will occur for the fraction of a second before the level is set correctly), it works quite well in real-world applications and prevents distorted recordings reliably.
Using stereo channels AutoSet operates ganged. AutoSet can be activated in TM FX or directly
at the unit in the channel settings. A push on Encoder 1/2 toggles AS on/off.
As soon as AutoSet reduces the gain the label AS, shown in the front display, changes its colour from black to dark blue.

20. Analog Outputs
20.1 Line
The short circuit protected, low impedance line outputs of channels 3 to 8 are available as 1/4"
TRS jacks on the back of the unit. The electronic output stage is built in a servo balanced design which handles unbalanced (mono jacks) and balanced (stereo jacks) correctly.
To maintain an optimum level for devices connected to the analog outputs, the Fireface UFX II
internally uses hi-quality electronic switches, which allow for a perfect adaptation of all outputs
individually to the three most often used studio levels.
As with the analog inputs, the analog output levels are defined to maintain a problem-free operation with most other devices. The headroom of the Fireface UFX II lies between 9 and 15 dB,
according to the chosen reference level:
Reference
Hi Gain
+4 dBu
-10 dBV
0 dBFS @
+19 dBu
+13 dBu
+2 dBV
Headroom
15 dB
9 dB
12 dB
The above levels are also found in all other RME devices. Therefore they are fully compatible to
each other.
The outputs 1 and 2 use XLR sockets. They additionally offer an output level of +24 dBu, making these outputs compatible to SMPTE (+24 dBu @ 0 dBFS, +4 dBu with 20 dB headroom):
Reference
+24 dBu
!
0 dBFS @
+24 dBu
Headroom
20 dB
The electronic driver circuit of the XLR outputs does not operate servo-balanced! When
connecting unbalanced equipment, make sure pin 3 of the XLR output is not connected. A
connection to ground will cause higher THD (distortion)!
20.2 Headphones / Line Out
Channels 9 to 12 of the Fireface are available on the front as 1/4" TRS jacks. These channels
use the same converters as the other Line outputs, therefore offer the same technical data (118
dBA SNR).
Two hardware-based reference levels are available (set in TotalMix Output Channel Settings,
Level, High or Low). High equals the setting Hi Gain of the other channels, Low equals -10 dBV
(see table above) with +4 dBu at digital full scale. They can thus also be used as high-quality,
yet unbalanced line outputs.
These outputs are special low impedance types (2 Ohms), ready to be used with headphones.
Setting the output level, i.e. the monitoring volume, is done – besides the pre-setting High/Low via TotalMix (Hardware Output, PH 9/10 and PH 11/12) or directly at the unit via the three encoders. Changing the monitoring volume is therefore very easy and quickly done.
User's Guide Fireface UFX II © RME
41
In case the Phones outputs should operate
as line outputs, an adapter TRS plug to RCA
phono plugs, or TRS plug to TS plugs is
required.
The pin assignment follows international
standards. The left channel is connected to
the tip, the right channel to the ring of the
TRS jack/plug.
21. Digital Connections
21.1 ADAT
The ADAT optical inputs of the Fireface UFX II are fully compatible with all ADAT optical outputs. RME's unsurpassed Bitclock PLL prevents clicks and drop outs even in extreme varipitch
operation, and guarantees a fast and low jitter lock to the digital input signal. A usual TOSLINK
cable is sufficient for connection.
ADAT1 In
Interface for the first or only device sending an ADAT signal to the Fireface UFX II. Carries the
channels 1 to 8. When receiving a Double Speed signal, this input carries the channels 1 to 4,
at Quad Speed the channels 1 and 2.
ADAT2 In
Interface for the second device sending an ADAT signal to the Fireface UFX II. Carries the
channels 9 to 16. When receiving a Double Speed signal, this input carries the channels 5 to 8,
at Quad Speed the channels 3 and 4. Can also be used as SPDIF optical input.
ADAT1 Out
Interface for the first or only device receiving an ADAT signal from the Fireface UFX II. Transmits channels 1 to 8. When sending a Double Speed signal, this port carries channels 1 to 4, at
Quad Speed the channels 1 and 2.
ADAT2 Out
Interface for the second device receiving an ADAT signal from the Fireface UFX II. Transmits
channels 9 to 16. When sending a Double Speed signal, this port carries channels 5 to 8, at
Quad Speed the channels 3 and 4. Can also be used as SPDIF optical output.
21.2 AES
The Fireface UFX II provides one XLR AES/EBU input and output each. Connection is accomplished using balanced cables with XLR plugs. Input and Output are transformer-balanced and
ground-free. The incoming channel status is ignored.
AES/EBU (and SPDIF) can contain Emphasis information. Audio signals with Emphasis have a
high frequency boost, requiring high frequency attenuation on playback.
!
42
An Emphasis indication gets lost as there exists no standardized interface on computers to
handle this information!
User's Guide Fireface UFX II © RME
Input
Thanks to a highly sensitive input stage
SPDIF coaxial can be fed too by using
a simple cable adapter phono/XLR. To
achieve this, pins 2 and 3 of a male
XLR plug are connected individually to
the two pins of a phono plug. The cable
shielding is only connected to pin 1 of
the XLR - not to the phono plug.
In AES operation, identical signals are available at both the optical and the XLR output. An obvious use for this would be to connect two devices, i.e. using the Fireface UFX II as a splitter
(distribution 1 to 2).
Output
Using the cable adapter XLR/phono described above, devices with coaxial SPDIF interface can
be connected to the AES output of the Fireface UFX II as well. Note that most consumer equipment with phono (SPDIF) inputs will only accept signals having a Channel Status ‘Consumer’
format. The Consumer status is activated in the Settings dialog of the Fireface UFX II. In Consumer mode the output voltage is reduced as well, as SPDIF calls for a lower voltage than
AES/EBU.
The output signal coding of the Fireface UFX II has been implemented according to AES3-1992

21.4 MIDI
Fireface UFX II offers two MIDI I/O via four 5-pin DIN sockets. The MIDI ports are added to the
system by the driver. Using MIDI capable software, these ports can be accessed under the
name UFX II MIDI Port.
The MIDI ports support multi-client operation. A MIDI input signal can be received from several
programs at the same time. Even the MIDI output can be used by multiple programs simultaneously. However, due to the limited bandwidth of MIDI, this kind of application will often show
various problems.
Note: The MIDI input LEDs display any kind of MIDI activity, including MIDI Clock, MTC and
Active Sensing. The latter is sent by most keyboards every 0.3 seconds.

22. Word Clock
22.1 Word Clock Input and Output
SteadyClock guarantees an excellent performance in all clock modes. Based on the highly efficient jitter suppression, the Fireface refreshes and cleans up any clock signal, and provides it
as reference clock at the BNC output (see chapter 39.8).
Input
The Fireface's word clock input is active when Clock Source in the Settings dialog has been
switched to Word, and a valid word clock signal is present. The signal at the BNC input can be
Single, Double or Quad Speed, the Fireface UFX II automatically adapts to it. As soon as a valid
signal is detected, the WC LED is lit, and the Settings dialog shows either Lock or Sync (see
chapter 39.1).
Thanks to RME's Signal Adaptation Circuit, the word clock input still works correctly even with
heavily mis-shaped, dc-prone, too small or overshoot-prone signals. Thanks to automatic signal
centering, 300 mV (0.3V) input level is sufficient in principle. An additional hysteresis reduces
sensitivity to 1.0 V, so that over- and undershoots and high frequency disturbances don't cause
a wrong trigger.
The Fireface UFX II word clock input can be not terminated or internally terminated (75 Ohms).
The state is comfortably selected within the Settings dialog. To terminate the input check the
option Word Clock In Term. under Input Options.
Output
The word clock output of the Fireface is constantly active, providing the
current sample frequency as word clock signal. As a result, in Master
mode the provided word clock is defined by the currently used
software. In Slave mode the provided frequency is identical to the one
present at the currently chosen clock input. When the current clock
signal fails, the Fireface UFX II switches to Master mode and adjusts
itself to the next, best matching frequency (44.1 kHz, 48 kHz etc.).
Selecting Single Speed in the Settings dialog causes the output signal to always stay within the
range of 32 kHz to 48 kHz. So at 96 kHz and 192 kHz sample rate, the output word clock is 48
kHz.
The received word clock signal can be distributed to other devices by using the word clock output. With this the usual T-adapter can be avoided, and the Fireface UFX II operates as Signal
Refresher. This kind of operation is highly recommended, because
•
•
•
input and output are phase-locked and in phase (0°) to each other
SteadyClock removes nearly all jitter from the input signal
the exceptional input (1 Vpp sensitivity instead of the usual 2.5 Vpp, dc cut, Signal Adaptation Circuit) plus SteadyClock guarantee a secure function even with highly critical word
clock signals
Thanks to a low impedance, short circuit proof output, the Fireface delivers 4 Vpp to 75 Ohms.
For wrong termination with 2 x 75 Ohms (37.5 Ohms), there are still 3.3 Vpp at the output.

22.2 Technical Description and Usage
In the analog domain one can connect any device to another device, a synchronization is not
necessary. Digital audio is different. It uses a clock, the sample frequency. The signal can only
be processed and transmitted when all participating devices share the same clock. If not, the
signal will suffer from wrong samples, distortion, crackle sounds and drop outs.
AES/EBU, SPDIF and ADAT are self-clocking, an additional word clock connection in principle
isn't necessary. But when using more than one device simultaneously problems are likely to
happen. For example any self-clocking will not work in a loop cabling, when there is no 'master'
(main clock) inside the loop. Additionally the clock of all participating devices has to be synchronous. This is often impossible with devices limited to playback, for example CD players, as
these have no SPDIF input, thus can't use the self clocking technique as clock reference.
In a digital studio synchronisation is maintained by connecting all devices to a central sync
source. For example the mixing desk works as master and sends a reference signal, the word
clock, to all other devices. Of course this will only work as long as all other devices are
equipped with a word clock or sync input, thus being able to work as slave (some professional
CD players indeed have a word clock input). Then all devices get the same clock and will work
in every possible combination with each other.
!
A digital system can only have one master! If the Fireface's clock mode is set to 'Master', all
other devices must be set to ‘Slave’.
But word clock is not only the 'great problem solver', it also has some disadvantages. The word
clock is based on a fraction of the really needed clock. For example SPDIF: 44.1 kHz word
clock (a simple square wave signal) has to be multiplied by 256 inside the device using a special PLL (to about 11.2 MHz). This signal then replaces the one from the quartz crystal. Big
disadvantage: because of the high multiplication factor the reconstructed clock will have great
deviations called jitter. The jitter of a word clock is typically 15 times higher as when using a
quartz based clock.
The actual end of these problems is offered by the SteadyClock technology of the Fireface
UFX II. Combining the advantages of modern and fastest digital technology with analog filter
techniques, re-gaining a low jitter clock signal of 22 MHz from a slow word clock of 44.1 kHz is
no problem anymore. Additionally, jitter on the input signal is highly rejected, so that even in real
world usage the re-gained clock signal is of highest quality.
User's Guide Fireface UFX II © RME
45
22.3 Cabling and Termination
Word clock signals are usually distributed in the form of a network, split with BNC T-adapters
and terminated with resistors. We recommend using off-the-shelf BNC cables to connect all
devices, as this type of cable is used for most computer networks. You will find all the necessary components (T-adapters, terminators, cables) in most electronics and/or computer stores.
The latter usually carries 50 Ohms components. The 75 Ohms components used for word clock
are part of video technology (RG59).
Ideally, the word clock signal is a 5 Volt square wave with the frequency of the sample rate, of
which the harmonics go up to far above 500 kHz. To avoid voltage loss and reflections, both the
cable itself and the terminating resistor at the end of the chain should have an impedance of 75
Ohm. If the voltage is too low, synchronization will fail. High frequency reflection effects can
cause both jitter and sync failure.
Unfortunately there are still devices on the market, even newer digital mixing consoles, which
are supplied with a word clock output that can only be called unsatisfactory. If the output breaks
down to 3 Volts when terminating with 75 Ohms, you have to take into account that a device, of
which the input only works from 2.8 Volts and above, does not function correctly already after 3
meter cable length. So it is not astonishing that because of the higher voltage, word clock networks are in some cases more stable and reliable if cables are not terminated at all.
Ideally all outputs of word clock delivering devices are designed as low impedance types, but all
word clock inputs as high impedance types, in order to not weaken the signal on the chain. But
there are also negative examples, when the 75 Ohms are built into the device and cannot be
switched off. In this case the network load is often 2 x 75 Ohms, and the user is forced to buy a
special word clock distributor. Note that such a device is generally recommended for bigger
studios.
The Fireface's word clock input can be high-impedance or terminated internally, ensuring maximum flexibility. If termination is necessary (e.g. because the Fireface is the last device in the
chain), check the option Word Clock In Term. under Input Options (see chapter 7.1 / 14.1).
In case the UFX+ resides within a chain of devices receiving word clock, plug a T-adapter into
its BNC input jack, and the cable supplying the word clock signal to one end of the adapter.
Connect the free end to the next device in the chain via a further BNC cable. The last device in
the chain should be terminated using another T-adapter and a 75 Ohm resistor (available as
short BNC plug). Of course devices with internal termination do not need T-adaptor and terminator plug.
!
Due to the outstanding SteadyClock technology of the Fireface UFX II, it is recommended
not to pass the input signal via T-adapter, but to use the Fireface's word clock output instead. Thanks to SteadyClock, the input signal will both be freed from jitter and - in case of
loss or drop out – be reset to a valid frequency.
22.4 Operation
The green Lock LED on the front (STATE) will light up as soon as a word clock signal is detected. To change to word clock as clock source, activate the Clock Source Word in the field
Clock Mode within the Settings dialog. The status display Current changes to Word as soon as
a valid signal is present at the BNC jack. This message has the same meaning as the green
State LED on the front, but appears on the monitor, i.e. the user can check immediately whether
a valid word clock signal is present and is currently being used.

47
23. Operation and Usage
23.1 General
Using the three rotary encoders and the clear colour display the Fireface UFX II can be configured and set up completely at the device. Additionally internal memory allows for the permanent
storage of six different states of the unit. Therefore the Fireface UFX II is able to operate fully
stand-alone, without any connected computer. In stand-alone operation it can transform into
totally different devices by the simple click of a button. Furthermore TotalMix FX, and with this
the application examples shown below, can also be controlled via MIDI, see chapter 28.6,
Stand-Alone MIDI Control.
23.2 Settings at the Unit
The Fireface UFX II has a simple menu structure, depending on the button pressed.
MIC/GAIN. First push brings up the Mic.Instr. Gain 9/10, second push Mic.Instr. Gain 11/12,
third push returns to the meter screen.
REC/PLAY. Brings up the Record/Playback (Direct USB Recording) menu, second push returns to the meter screen.
CHAN/MIX. First push brings up the Channel menu, second push the Mix to menu, third push
returns to the meter screen. In the Channel menu encoder 1 selects the input and output to be
configured, encoder 2 selects the function to be configured. These are Settings, Low Cut, Parametric EQ, Compressor/Expander and Auto Level.
The Mix to menu gives access to the whole submix functionality. Encoder 1 selects the mix
destination, encoder 2 the source. A source can be modified in mix level and panorama.
SETUP/REV. Encoder 1 selects Setups, Options and Reverb/Echo. Options has the subpages
Clock Options, HW Options/Diagnosis and Control Room Options. Reverb/Echo has the subpages Reverb and Echo. The subpages are selected by encoder 2.
23.3 Store / Load Setups at the Unit
After hitting the key SETUP/REV, turning encoder 1 changes to Setups. First select the preferred memory slot, then the desired process (load or store). The load/store process is completed by pushing encoder 2 for more than one second.
The UFX+ has six memory slots for free usage. Three fixed slots offer convenient and quick
reset and configuration of the unit:
Factory. Sets the unit into factory default state.
AD/DA A. Configures an ADAT analog to digital and vice versa converter (12 analog I/Os).
23.4 Storing Setups from the Computer
Setups can also be loaded into the unit from the computer. As the Setups are usually generated
at the computer the final step of transmission offers a convenient workflow. In TotalMix FX use
Options / Store current state into device to select the desired storage place (Setup) within the
unit.

24. Examples
24.1 12-Channel AD/DA-Converter
TotalMix' super-flexible routing functions make it easy to turn the UFX into a 12-channel AD/DA
converter, analog from/to ADAT.
It’s easy to build the setup. For a clean start perform a Total Reset from the Options menu.
Then select the ADAT Output 1/2 in the third row, and pull up the fader of the Analog input 1/2
in the first row. Then select ADAT 3/4, pull up Analog 3/4 and so on until all 12 analog inputs
are routed to the corresponding 12 (8+4) ADAT channels.
Now do the same for the analog outputs: select Analog Output 1/2 and move the fader of ADAT
Input 1/2 to 0 dB, and so on. An additional monitoring of all or selected I/Os can be easily set up
for the AES output, or as analog mixdown on one of the phones outputs.
24.2 4-Channel Mic Preamp
Use TotalMix to route the four microphone inputs directly to the analog outputs. This turns the
Fireface UFX II into a 4-channel microphone preamp. The AD- and DA-conversion will cause a
small delay of the signals of around 0.1 ms (at 192 kHz, see chapter 39.2). But this is nothing to
worry about, as it is the same delay that would be caused by changing the microphone's position by about 3.3 centimeter (1.3 inches).
24.3 Monitor Mixer
TotalMix allows ANY configuration of all I/Os of the Fireface. For example, set up the device as
monitor mixer for 12 analog signals, 16 digital via ADAT and 2 via AES. Additionally, TotalMix
lets you set up ANY submixes, so all existing outputs can be used for different and independent
monitorings of the input signals. The perfect headphone monitor mixer!
24.4 Digital Format Converter
As TotalMix allows for any routing of the input signals, the Fireface UFX II can be used as
ADAT to AES converter, ADAT to two ADAT splitter and AES to ADAT converter.
24.5 Analog / Digital Routing Matrix
The Matrix in TotalMix enables you to route and link all inputs and outputs completely freely. All
the above functionalities are even available simultaneously, can be mixed and combined in
many ways. Simply said: the Fireface UFX II is a perfect analog/digital routing matrix!
24.6 Stand-Alone Recorder/Player
The UFX II can be used for recording as well as playback of audio signals. As all settings are
available directly at the unit it is possible to record a live concert completely without a computer.
Music that was copied to a USB thumb drive before can be played back any time. Of course
both in combination to any of the other examples above!

25. Routing and Monitoring
25.1 Overview
The Fireface UFX II includes a powerful digital real-time mixer, the Fireface UFX II mixer, based
on RME’s unique, sample-rate independent TotalMix technology. It allows for practically unlimited mixing and routing operations, with all inputs and playback channels simultaneously, to any
hardware outputs. TotalMix FX adds 3-band parametric Equalizer, Low Cut, Echo, Reverb,
Compressor, Expander and Auto Level.
Here are some typical applications for TotalMix:
• Setting up delay-free submixes (headphone mixes). The Fireface UFX II allows for up to 15
fully independent stereo submixes. On an analog mixing desk, this would equal 30 Aux
sends.
• Unlimited routing of inputs and outputs (free utilisation, patchbay functionality).
• Distributing signals to several outputs simultaneously. TotalMix offers state-of-the-art splitter
and distributor functions.
• Simultaneous playback of different programs via a single stereo output. The ASIO multiclient driver supports the usage of several programs at the same time. If this happens on different playback channels TotalMix provides the means to mix and monitor these on a single
stereo output.
• Mixing of the input signal to the playback signal (complete ASIO Direct Monitoring). RME is
not only the pioneer of ADM, but also offers the most complete implementation of the ADM
functions.
• Integration of external devices. Use TotalMix to insert external effects devices, be it in the
playback or in the record path. Depending on the current application, the functionality equals
insert or effects send and effects return, for example as used during real-time monitoring
when adding some reverb to the vocals.
Every single input channel, playback channel and hardware output features a Peak and RMS
level meter, calculated in hardware. These level displays are very useful to determine the presence and routing destinations of the audio signals.
For a better understanding of the TotalMix mixer you should know the following:
• As shown in the block diagram (next page), the record signal usually stays un-altered. TotalMix does not reside within the record path, and does not change the record level or the
audio data to be recorded (exceptions: EQ+D for Record and Loopback mode).
• The hardware input signal can be passed on as often as desired, even with different levels.
This is a big difference to conventional mixing desks, where the channel fader always controls the level for all routing destinations simultaneously.
• The level meters of input and playback channels are connected pre-fader, to be able to
visually monitor where a signal is currently present. The level meters of the hardware outputs are connected post-fader, thus displaying the actual output level.

25.2 The User Interface
The visual design of the TotalMix mixer is a result of its capability to route hardware inputs and
software playback channels to any hardware output. The Fireface UFX II has 30 input channels,
30 software playback channels, and 30 hardware output channels:
TotalMix can be used in the above view (View Options 2 Rows). However, the default is a vertical alignment in three rows as known from an Inline desk, so that the row Software Playback
equals the Tape Return of a real mixing desk:
• Top row: Hardware inputs. The level shown is that of the input signal, i.e. fader independent.
Via fader and routing menu, any input channel can be routed and mixed to any hardware
output (bottom row).
• Middle row: Playback channels (playback tracks of the audio software). Via fader and routing
menu, any playback channel can be routed and mixed to any hardware output (bottom row).
• Bottom row: Hardware outputs. Here, the total level of the output can be adjusted. This may
be the level of connected loudspeakers, or the level of any submix.
Usage in mode Submix View (Default): simply click on the hardware output channel where
you want to have an audio signal. This channel turns brighter, means it is selected as current
submix. Now move the faders up from all sources - input and playback channels - that you want
to hear at the submix output.
The following chapters explain step by step all functions of the user interface.

User's Guide Fireface UFX II © RME
25.3 The Channels
A single channel can be switched between mono and stereo mode. The mode is set in the
channel settings.
Channel name. The name field is the preferred place to select a channel by a mouse click. A
double click opens a dialog to assign a different name. The original name will be shown when
activating the option Names in the View Options.
Panorama. Routes the input signal freely to the left and right routing destination
(lower label, see below). The level reduction in center position is -3 dB.
Mute and Solo. Input channels and playback channels each have a mute and solo
button.
Numerical level display. Shows the current RMS or Peak level, updated twice per
second. OVR means overload. The setting Peak/RMS is changed in the View
Options.
Level meter. The meter shows both peak values (zero attack, 1 sample is enough
for a full scale display) by means of a yellow line, and mathematically correct RMS
values by means of a green bar. The RMS display has a relatively slow time constant, so that it shows the average loudness quite well. Overs are shown in red at
the top of the bar. In the Preferences dialog (F2) the Peak Hold time, the over
detection and the RMS reference can be set.
Fader. Determines the gain/level of the signal routed to the current routing destination (lower
label). Please note that this fader is not the fader of the channel, but only the fader of the current routing. Compared to a standard mixing desk TotalMix does not have a channel fader, but
only Aux Sends, as many as there are hardware outputs. Therefore TotalMix can create as
many different Submixes as there are hardware outputs. This concept is understood best in the
Submix View, but more on that later.
Below the fader the Gain is shown in a numerical display field,
according to the current fader position. The fader can be:
¾
dragged with the left mouse button pressed
¾
moved by the mouse wheel
¾
set to 0 dB and −∞ by a double click. The same happens
with a single click plus held down Ctrl key.
¾
adjusted in fine mode by mouse drag and mouse wheel
when holding the Shift key down
A Shift-click on a fader adds the fader to the temporary fader
group. All faders now marked yellow are ganged, and move
simultaneously in a relative way. The temporary fader group is
deleted by a click on the F symbol in the upper right of the
window.
The arrow symbol at the bottom minimizes the channel width to that of the level meters. Another click maximizes it again. A mouse click with held Ctrl key causes all channels to the right
to enlarge and minimize at once.
User's Guide Fireface UFX II © RME
55
The lowest field shows the current routing target. A mouse click
opens the routing window to select a routing target. The list shows
all activated routings of the current channel by arrows in front of the
listed entries, the current one is shown in bold letters.
An arrow is only shown with an activated routing. A routing is seen
as activated when audio data is sent. As long as the fader is set to
−∞ the current routing will be shown in bold letters, but not have an
arrow in the front.
Trim Gain. After a click on the T-button one channel’s faders are all synchronized. Instead of
changing only a single routing the fader affects all the channel’s active routings. For a better
overview the faders currently not visible are indicated by orange triangles beside the fader path.
When moving the fader the triangles also move to a new position, equalling the invisible faders’
new settings.
Note that the fader button is automatically set to the highest routing gain of all routings so that
best control is offered. The gain (fader knob position) of the currently active routing (the submix
selected in the third row) is shown as white triangle.
Background: TotalMix has no fixed channel fader. In case of the Fireface UFX II there are 30
mono Aux sends, shown alternately as single fader within the channel strip. The high number of
Aux sends enables multiple and fully independent routings.
In some cases it is necessary to synchronize the gain changes of these routings.
An example is the Post fader function, where a change of the singer’s volume shall
be performed identical to the volume change of the signal sent to the reverb
device, so that the reverb level keeps its relation to the original signal. Another
example is the signal of a guitar that is routed to different submixes, means
hardware outputs, which gets much too loud during the solo part, and therefore
needs to be reduced in volume on all outputs simultaneously. After a click on the
Trim button this can be done easily and with a perfect overview.
As all channel’s routings change simultaneously when Trim is active, this mode
basically causes the same behaviour as a trim pot within the input channel,
affecting the signal already before the mixer. That’s how this function got its name.
In the View Options / Show the function Trim Gains can be globally switched on
and off for all channels. The global Trim mode is recommended when using
TotalMix FX as live mixing desk.
The Context Menu. With a right click on the input, playback and output channels their context
menus provide advanced functionality (these menus are also available in the Matrix, but only
directly on the channel labels). The entries are self-explanatory and automatically adjust to
where the click is performed. The input channels offer Clear, Copy input, paste the input mix
and paste its FX. On a playback channel Copy, Paste and Clear the playback mix are available.
On an output channel Copy and Mirror functionality for the current submix and copying of the
FX settings is offered.
56
User's Guide Fireface UFX II © RME
25.3.1 Settings
A click on the tool symbol opens the channel’s Settings panel with differing elements. For example the option Inst exists only in input channels 9-12, and the ADAT channels do not offer the
phantom power option.
Stereo. Switches the channel to mono or stereo mode.
48V. Activates phantom power at the corresponding input. Serves as
power supply for high quality condenser mics. This option should stay
off with other sources to prevent failure by spikes.
Inst. Switches inputs 9 to 12 individually from XLR to the TRS jack.
Gain (9-12). Sets the gain for the four front inputs. The knob can be
adjusted by dragging the mouse or by the mouse wheel. This also
works when the mouse has been moved over the two gain displays.
Then the gain can be changed separately for left and right channel,
even when the channel is in stereo mode.
Gain (1-8). Additionally to the reference level setting, Line inputs 1 to 8
have an adjustable gain option from 0 dB to +12 dB.
Level. Sets the reference level individually for the 8 rear Line inputs.
The available settings are +4 dBu and LoGain.
AutoSet. Activates an automatic gain reduction preventing overloads caused by too high gain
settings. See chapter 19.2 for details.
Width. Defines the stereo width. 1.00 equals full stereo, 0.00 mono, -1.00 swapped channels.
FX Send. Setting the level of the signal sent to the FX bus which feeds Echo and Reverb. The
current setting is also visible with closed channel settings, because knob and small fader are
always synchronized. To make this function as useful as possible FX Send is locked to the
highest submix, thus imitating the Aux Post Fader function of a standard mixing desk. When
moving the big fader both knob and small fader will also move. This way the reverb signal will
always have the same relation to the dry signal.
The level of the signal sent to the effects can be controlled by the FX In level meters of the FX
window. It becomes visible after a click on FX in the View Options.
MS Proc. Activates M/S processing within the stereo channel. Monaural information is sent to
the left channel, stereo information to the right.
Phase L. Inverts the phase of the left channel by 180°.
Phase R. Inverts the phase of the right channel by 180°.
Note: the functions Width, MS Proc, Phase L and Phase R affect all routings of the respective
channel.
User's Guide Fireface UFX II © RME
57
Besides Stereo/Mono, Phase L und Phase R the settings of the Hardware Outputs have further
options:
Level. Sets the reference levels of the 8 analog Line outputs. The
available settings are -10 dBV, +4 dBu and HiGain. The outputs 1/2
additionally offer +24 dBu. The Phones (channels 9-12) have a Low and
High setting to choose from.
FX Return. The effect signal (Echo and Reverb) is mixed to the
respective hardware output by the duo knob/small fader.
Talkback. Activates this channel as receiver and output of the Talkback
signal. This way Talkback can be sent to any outputs, not only the
Phones in the Control Room section. Another application could be to
send a certain signal to specific outputs by the push of a button.
No Trim. Sometimes channels need to have a fixed routing and level,
which should not be changed in any case. An example is the stereo
mixdown for recording of a live show. With No Trim active, the routing to
this output channel is excluded from the Trim Gains function, therefore is
not changed unintentionally.
Loopback. Sends the output data to the driver as record data. The corresponding submix can
be recorded then. This channel’s hardware input sends its data only to TotalMix, no longer to
the recording software.
Another difference to the input and playback channels is the Cue button instead of Solo. A click
on Cue sends the respective Hardware Output’s audio to the Main Out, or any of the Phones
outputs (option Assign / Cue to in the Control Room section). With this any hardware output can
be controlled and listened to through the monitoring output very conveniently.
25.3.2 Equalizer
A click on EQ opens the Equalizer panel. It is available in all input and output channels, and
affects all routings of the respective channel (pre fader). The panel includes a low cut and a 3band parametric equalizer which can be activated separately.
EQ. Activated by the EQ button.
Type. Band 1 and 3 can operate in peak (bell) or shelf
(shelving) mode. The middle band is fixed to peak mode.
Band 3 can also operate as Hi Cut (low pass filter),
especially useful for LFE and subwoofer purposes.
Gain. All three bands can change their amplification
between +20 dB to -20 dB.
Freq. The center frequency of the filters is adjustable
between 20 Hz and 20 kHz. While in peak mode the center
frequency is adjusted, in shelf mode the cut-off point (-3 dB)
will be changed.
Q. The Quality factor of the filter is adjustable from 0.7
(wide) to 5.0 (narrow).
Lo Cut. Activated by the button Lo Cut. The slope of the high-pass filter is adjustable between
6, 12, 18 and 24 dB per octave. The cut-off point (-3 dB) is adjustable between 20 Hz and 500
Hz.
58
User's Guide Fireface UFX II © RME
The frequency graphics give a precise overview of the filter results. Overlapping filters influence
each other. This can be used to achieve more than 20 dB amplitude, or to generate difficult
frequency response optimizations.
Note: TotalMix has an internal headroom of 24 dB. Extreme boosts with overlapping filters can
therefore cause an internal overload. In any case such an overload is displayed by the Over
LED of the channel’s level meter.
Preset. Settings of the EQ and the Low Cut
can be stored, loaded, and copied between
channels at any time. A click on Preset opens
a menu with several entries:
¾
Recall: Presets stored before by the user
can be selected and loaded
¾
Save to: There are 16 storage places
available (EQ Preset 1 to 16)
¾
Import: Loads a previously stored TM EQ
file (.tmeq)
¾
Export: Stores the current state as TM
EQ file (.tmeq)
¾
Factory: Includes 14 examples for the
creative use of Low Cut and Equalizer
¾
Reset: Resets the Low Cut and EQ to
have zero influence (Gain 0 dB)
¾
Rename: The EQ Presets 1 to 16 can be renamed. The changes will be shown in both lists
Recall and Save to.
Notes on the EQ Presets
Copy between channels: The EQ Preset menu of all channels is identical. If an EQ setup is
stored via Save to on one of the 16 storage places, it is then also available in any other channel
via Recall.
Copy between Snapshots: The Presets are not saved in Snapshots, therefore do not change
when a different Snapshot is loaded. Presets are saved in Workspaces and also loaded with
these.
Copy between Workspaces: is done by the export and import function of the Preset menu.
Important and useful Presets should always be saved as TM EQ file, so that they can not get
lost even on accidental overwrite.
Factory Presets: loaded like all Presets the settings of both Low Cut and EQ simultaneously.
The current state, On or Off, is neither saved nor activated on load. With this a preset can be
loaded anytime, but will not become active before the user decides to switch the EQ and/or LC
on – except they had been active already before the load process. For this reason some Factory Presets have special names. For example Telephone (LC+EQ) will sound much better
when the LC has been activated additionally to the EQ, as the LC is set to an unusual high frequency of 500 Hz here.

25.3.3 Dynamics
A click on D opens the Dynamics panel with Compressor, Expander and Auto Level. They are
available in all input and output channels, and affects all routings of the respective channel.
Dynamics. Activated by this button.
Thresh. Threshold where Compressor or Expander start to
work. The Compressor is adjustable from -60 dB to 0 dB,
the Expander is adjustable from -99 dB to -20 dB.
Ratio. Ratio of input to output signal. Defines the intensity
of the signal processing. Adjustable from 1 to 10.
Gain. Gain stage to compensate a loss in level caused by
the Compressor. Adjustable from -30 to +30 dB. With
inactive Compressor (Threshold 0 dB, Ratio 1:1) this
function can also be used as universal digital gain stage.
Attack. Defines the rise time for the control voltage of
Compressor/Expander. Adjustable from 0 ms to 200 ms.
Release. Defines the release time for the control voltage of
Compressor and Expander. Adjustable from 100 ms to 999 ms.
The amplitude graphics give a precise overview of the level changes caused by the current
settings of Compressor and Expander. The white dot shows the level of the input signal and
with this whether the signal is within the processing range or not. The small light blue lines in
the level meter show the currently active gain reduction. Settings for these Dynamic Meters are
found in the Preferences dialog (F2).
Auto Level. Activated by this button.
Max. Gain. Defines the maximum amplification of the input signal. Adjustable from 0 dB to 18
dB.
Headroom. To minimize short-time overloads
and clipping of the signal peaks Auto Level can
be set to operate at a fixed offset to 0 dBFS.
Adjustable from 3 dB to 12 dB.
Rise Time. Defines the speed of a level increase
after a level reduction. Adjustable from 0.1 s to
9.9 s.
Preset. Includes the same functions as
described on the previous page for the Equalizer.
The names of the Factory Presets make clear
whether Compressor, Auto Level or both (C+A)
have to be switched on.

25.4 Section Control Room
In the section Control Room the menu Assign defines the Main Out which is used for listening
in the studio. For this output the functions Dim, Recall, Mono, Talkback, External In and Mute
FX are automatically applied. At the unit the VOLUME knob follows this assignment.
Additionally the channel will be shifted from the Hardware
Outputs into the Control Room section, and renamed Main.
The same happens when assigning Main Out B or the
Phones. The original name can be displayed by the function
Names in the View Options menu at any time.
Phones 1 to 4 will have Dim (set in Settings) and a special
routing applied when Talkback is activated. Putting them
beside the Main Out increases the overview within the output
section greatly.
Dim. The volume will be reduced by the amount set in the
Settings dialog (F3).
Recall. Sets the gain value defined in the Settings dialog.
Speaker B. Switches playback from Main Out to Main Out B.
The faders of the channels Main and Speaker B can be
ganged via Link.
Mono. Mixes left and right channel. Useful to check for mono compatibility and phase problems.
Talkback. A click on this button will dim all signals on the Phones outputs by an amount set up
in the Preferences dialog. At the same time the control room's microphone signal (source defined in Preferences) is sent to the Phones. The microphone level is adjusted with the channel's
input fader.
External Input. Switches Main monitoring from
the mix bus to the stereo input defined in the
Settings dialog (F3). The relative volume of the
stereo signal is adjusted there as well.
Mute FX. Mutes Reverb and Echo on the Main
Out, to hear the mix without those effects.
Assign. Allows to define the Main Out, Main Out
B (Speaker B), and up to four Phones outs.
The output for the Cue signal, which is usually
Main, can also be set to one of the Phones outputs. This setting also controls the PFL
monitoring.
User's Guide Fireface UFX II © RME

25.5 The Control Strip
The Control Strip on the right side is a fixed element. It combines different functions that are
either required globally, or constantly used, and therefore should not be hidden in a menu. It
can still be hidden via the top menu Window – Hide Control Strip.
The areas described in the following chapters can be minimized by a click on the arrow in their
title bar.
Device selection. Select the unit to be controlled in case more than one is installed on the
computer.
FX - DSP Meter. Shows the DSP load caused by activated EQ, Low Cut,
Compressor, Auto Level, Echo and Reverb. The DSP of the Fireface UFX II
has an automatic load limiter. If no DSP resources are left further effects can
not be activated. When switching to DS and QS modes effects will be
deactivated automatically until the DSP is not overloaded anymore.
Undo / Redo. With the unlimited Undo and Redo changes of the mix can be
undone and redone, at any time. Undo/Redo does not cover graphical
changes (window size, position, channels wide/narrow etc.), and also no
changes to the Presets. The accidental overwrite of an EQ Preset can not be
made undone.
Undo/Redo also operates across Workspaces. Therefore a completely
differently set up mixer view can be loaded via Workspace, and with a single
click on Undo the previous internal mixer state is returned – but the new mixer
view stays.
Global Mute - Solo - Fader.
Mute. Global Mute operates in a pre fader style, muting all currently activated routings of the
channel. As soon as any Mute button is pressed, the Mute Master button lights up in the Control
Strip area. With this button all selected mutes can be switched off and on again. One can comfortably set up a mute group or activate and deactivate several mute buttons simultaneously.
Solo. As soon as any Solo button is pressed, the Solo Master button lights up in the Control
Strip area. With this button all selected Solos are switched off and on again. Solo operates as
Solo-in-Place, post fader style, as known from common mixing desks. A typical limitation for
mixing desks, Solo working only globally and only for the Main Out, does not exist in TotalMix.
Solo is always activated for the current submix only.
Fader. A Shift-click on a fader adds the fader to the temporary fader group. All faders now
marked yellow are ganged, and move simultaneously in a relative way. The temporary fader
group is deleted by a click on the F symbol.
62
User's Guide Fireface UFX II © RME
25.5.1 View Options
The field Show combines different functions of routing, the level meters and the mixer view.
Routing Mode
¾
Submix. The Submix view (default) is the preferred view and delivers the
quickest overview, operation and understanding of TotalMix. The click on
one of the Hardware Output channels selects the respective submix, all
other outputs are darkened. At the same time all routing fields are set to
this channel. With Submix view, it is very easy to generate a submix for
any output: select the output channel, adjust the fader and pans of first
and second row – finished.
¾
Free. The Free view is for advanced users. It is used to edit several
submixes simultaneously, without the need to change between them.
Here one works with the routings fields of the input and playback channels
only, which then show different routing destinations.
Level Meters
¾
Post FX. Switches all level meters before (pre) or after (post) the effects. Level changes by
these can be easily checked using this feature. Additionally the input signal can be checked
for overloads. It is recommended to use Post FX as default setting, as the extreme reduction of a signal by LC/EQ is very seldom. Also all OVR displays of all level meters operate
both pre and post, efficiently preventing overloads going unnoticed.
¾
RMS. The numerical level display in the channels displays peak or RMS.
Show
¾
FX. Opens the window to set up the effects Reverb and Echo.
¾
Trim. Activates all Trim buttons on all channels. TotalMix thus behaves like a conventional,
simple mixing desk. Each fader affects all active routings of the channel simultaneously, as
if the fader were a trim-pot in the hardware input.
¾
2 Row. Switches the mixer view to 2 rows. Hardware Inputs and Software Playbacks are
placed side by side. This view saves a lot of space, especially in height.
¾
Names. Display of the original names of channels when they had been renamed by the
user.
User's Guide Fireface UFX II © RME
63
25.5.2 Snapshots - Groups
Snapshots. Snapshots include all mixer settings, but no graphical elements like window positions, window size, number of windows, visible EQs or Settings, scroll states, Presets etc. Only
the state wide/narrow of the channels is registered. Moreover the Snapshot is only temporarily
stored. Loading a Workspace causes the loss of all stored Snapshots, when these all had not
been saved before in a Workspace, or separately via File / Save Snapshot as. Via File / Load
Snapshot the mixer states can be loaded individually.
Eight different mixes can be stored under individual names in the Snapshot
section. A click on any of the eight buttons loads the corresponding Snapshot.
A double click on the name field opens the dialog Input Name to edit the
name. As soon as the mixer state is changed the button starts flashing. A click
on Store lets all buttons flash, whereby the last loaded one, the base of the
current state, flashes inversely. The storage finishes by clicking the desired
button (means storage place). The storage process is exited by another click
on the flashing Store button.
The area Snapshots can be minimized by a click on the arrow in the title bar.
Groups. The area Groups provides 4 storage places each for fader, mute and
solo groups. The groups are valid per Workspace, being active and usable in
all 8 Snapshots. But with this they are also lost when loading a new
workspace, in case they have not been saved before in a different
Workspace.
Note: The Undo function will help in case of an accidental overwrite or
deletion of the groups.
TotalMix uses flashing signals to guide you through the group setup. After a click on Edit and
click on the desired storage place all desired functions for this group have to be activated or
selected. The storage process is finished by another click on Edit.
When setting up a fader group make sure to not add faders that are at the top or low position,
unless all faders of that group have this position.
The Mute groups operate – other than the global mute – exclusively for the current routing. This
way you can not mute signals on all outputs unintentionally. Instead signals can be muted on
specific submixes by the push of a button.
A solo group operates exactly like the global solo, signals outside the current routing are not
affected.
25.5.3 Channel Layout - Layout Presets
To maintain overview within TotalMix FX channels can be hidden. Channels can also be excluded from being remoted. Under Options / Channel Layout a dialog lists all I/Os with their
current state. Selecting one or several channels enables the options to the right:
¾
¾
¾
64
Hide Channel in Mixer/Matrix. The selected channels are no longer shown in TotalMix FX,
nor are they available via MIDI or OSC remote control.
Hide Channel in MIDI Remote 1-4. The selected channels are hidden for MIDI remote (CC
and Mackie Protocol).
Hide Channel in OSC Remote 1-4. The selected channels are hidden for OSC remote
control.
User's Guide Fireface UFX II © RME
Hidden channels in Mixer/Matrix are still fully functional. An existing routing/mixing/FX processing stays active. But as the channel is no longer visible it can not be edited anymore. At the
same time the hidden channels are removed from the list of remote controllable channels, to
prevent them from being edited unnoticed.
Hidden channels in MIDI Remote x are removed from the list of remote controllable channels.
Within an 8-channel block of a Mackie compatible control they are skipped. The control therefore is no longer bound to consecutive orders. For example it will control channels 1, 2, and 6 to
11, when channels 3 to 5 are hidden.
The same can be done for OSC. With unnecessary channels made invisible for the OSC remote the more important channels are available as one block on the remote.
The dialog can be
called directly from
TotalMix by a right
mouse click on any
channel. The corresponding channel
will then be preselected
in
the
dialog.
The rows Inputs,
Playbacks
and
Outputs are set up
individually by the
tabs at the top. In
Use shows which
channels are currently used in the
mixing process.
In the above example the AES input channel has been made invisible. When AES is not used
this is an easy way to remove it from the mixer completely. A more complex setup would be to
only show all channels of the drum section, the horn section or the violins.
After finishing those settings the whole state can be stored as Layout Preset.
A click on Store and the desired memory slot makes the current channel
layout recallable anytime. The button All makes all channels temporarily
visible again.
With a simple click on a button it will then be possible to easily switch views of
only the channels involved with the mixing of the drum section, the horn
section, the violins, or any other useful view. An optimized remote layout can
be activated here as well, with or without visible changes. Double-click the
default slot name to enter any other name.
!
Layout Presets are stored within the Workspace, so make sure to save the current state
before loading a different Workspace!
The button Sub activates another useful special view. When in Submix view, Sub will cause all
channels to disappear that are not part of the currently selected Submix/Hardware Output. Sub
temporarily shows the mix based on all channels from Inputs and Playback row, independent
from the current Layout Preset. That makes it very easy to see and to verify which channels are
mixed/routed to the current output. Sub makes checking and verifying of mixes, but also the mix
editing itself, a lot easier, and maintains perfect overview even with lots of channels.

25.5.4 Scroll Location Markers
Another feature to improve overview and working with TotalMix FX are scroll location markers
(TotalMix view only). These are displayed automatically when the horizontal size of the TotalMix
FX window is smaller than the channel display requires. Shown on the right side of the scrollbar
of each row they have four elements:
¾
¾
¾
¾
Arrow to the left. A left mouse click
let the channels scroll to the very
first one, or most left.
1. Marker number 1. Scroll to the
desired position and perform a right
mouse click on 1. A dialog comes
up with precise information. Once
stored, a left mouse click will scroll
the channels to the stored position.
2. Marker number 2. See 1 for
details.
Arrow to the right. A left mouse
click let the channels scroll the last
one, or most right.
Location markers are stored in the
Workspace.
Application Examples
While originally added to improve navigation in the HDSPe MADI FX (having 196 channels that
never fit on any screen), the scroll location markers are also helpful with units having less channels:
•
•
66
When the TotalMix FX window is intentionally made small in width, so only a few channels
are shown.
When some or all EQ or Dynamics panels are open. Then all relevant settings are always
visible, but require a lot of space horizontally.
User's Guide Fireface UFX II © RME
25.6 Reverb and Echo
A click on FX in the View Options / Show brings up the Output FX panel. Here all parameters
for the effects Reverb and Echo are adjusted.
Reverb. Activated by the On button.
Type. Lists different reverb types for selection. Available are:
¾
Rooms Small, Medium, Large, Walls. Room simulation of rooms
in different size and behaviour.
¾
Shorty provides a short, rich and warm reverb.
¾
Attack slaps back.
¾
Swagger enriches and blows up the original sound source.
¾
Old School is just that.
¾
Echoistic has a heavy echo part within the reverb sound which
brings some nice stereo effect as well.
¾
8plus9 is a mixture of Old School and Echoistic.
¾
Grand Wide stands for a wide and open room and space.
¾
Thicker can be used as short reverb to enrich the original signal.
¾
Space has the most sizzle and longest reverb time.
¾
Envelope. Reverb effect where the volume course (envelope) is
freely adjustable.
¾
Gated. Simpler version of the Envelope reverb for cut reverb
effects.
Please note that all these reverb types are extremely flexible due to the
available Smooth and Room Scale controls. Most of them can be used
as short and long reverb, and sound totally different with Smooth turned
to maximum or minimum.
TotalMix FX comes with factory presets and default values for all reverb types to ensure a fast

General Settings
PreDelay. Delay of the reverb signal. Adjustable from 0 ms up to 999 ms.
Low Cut. High-pass filter before the reverb generation, removes low frequency signals which
should not cause a reverb sound. Adjustable from 20 Hz up to 500 Hz.
High Cut. Low-pass filter after the reverb generation. A reduction of the treble often lets the
reverb sound more natural. Adjustable from 5 kHz up to 20 kHz.
Smooth. Softens the reverb effect, affects stereo width, density and sound colour. Adjustable
from 0 up to 100.
Width. Adjusts the stereo width of the reverb signal from 100 (stereo) to 0 (mono).
Volume. Adjusts the level of the reverb effects signal sent to the FX return bus.
Special Settings for Room Types
Room Scale. Determines the size of the room, thus changing density and length of the reverb
effect. Adjustable from 0.5 up to 3.0.
Special Settings for Envelope and Gated
Attack. Length of time for the volume increase of the reverb signal. Also called rise time. Adjustable from 5 ms up to 400 ms.
Hold. Length of time for the fixed volume part of the reverb signal. Adjustable from 5 ms up to
400 ms.
Release. Length of time for the volume decrease of the reverb signal. Adjustable from 5 ms up
to 400 ms.
Special Settings for Space
Reverb Time. Sets the duration of the reverb referenced to a volume drop of 20 dB. Adjustable
from 0.1 s up to 4.9 s.
High Damp. Sets the treble damping over time for the reverb signal. In principle, this is a lowpass filter like High Cut. Because of the operation principle of this reverb it shows a slightly different behaviour. Adjustable from 5 kHz up to 20 kHz.

Echo. Activated by the On button.
Type. Lists different echo algorithms for selection. Available are:
¾
Stereo Echo. Separated echo generators on left and right channel. As a result the echo
follows the sound source within the stereo field.
¾
Stereo Cross. Echo generator on left and right channel with cross coupled feedback which
is only working for the stereo parts of the input signal. In case the input signal is only left or
right the Stereo Cross acts exactly like the Pong Echo.
¾
Pong Echo. Generates an echo that jumps between left and right channel, independent
from the source signal’s stereo position.
Settings
Delay Time. Sets the delay time for the first echo.
BPM. A double click on the lower value field offers a delay adjustment as Beats Per Minute.
Feedback. Feedback to produce further echoes.
Width. Adjusts the stereo width of the echo signal from 100 (stereo) to 0 (mono).
Volume. Adjusts the level of the echo effects signal sent to the FX return bus.
High Cut (HC). Option for more natural sound or intentional damping of the delayed signal.
Preset. Settings of the Reverb and the Echo can be stored, loaded, and copied between channels at any time. A click on Preset opens a menu with several entries:
¾
Recall: Presets stored before by the user
can be selected and loaded
¾

25.7 Preferences
The dialog Preferences can be opened via the Options menu or directly via F2.
Level Meters
¾ Full scale samples for OVR. Number
of consecutive samples to trigger an
over detection (1 to 10).
¾ Peak Hold Time. Hold time of the peak
value. Adjustable from 0.1 up to 9.9 s.
¾ RMS +3 dB. Shifts the RMS value by +3
dB, so that full scale level is identical for
Peak and RMS at 0 dBFS.
Mixer Views
¾ FX Send follows highest Submix.
Locks the FX Send knob to the channel
fader. As TotalMix supports multiple
routings per channel, a definition is
needed which fader (only one is visible)
is the one that FX Send will follow. This
is always the one with the highest fader
position, means the highest gain.
¾ FX Send follows Main Out. Locks the
FX Send knob to the channel fader only
for the Main Out submix. This is a typical
Live feature, where the FX Send is
always tied to the fader for the most
important output - the Main Out. When
adjusting other submixes the FX send
will not follow the fader movement.
¾ Center Balance/Pan when changing
Mono/Stereo. When switching a stereo
channel into two mono channels the
pan-pots are set fully left and right. This
option will set them to center instead.
¾ Disable double click fader action.
Prevents unintentional gain settings, for
example when using sensitive touchpads.
Dynamic Meters
¾ Compressor/Expander. Activates the
display of the Compressor/Expander’s
gain reduction as thin blue line in the
level meters of the corresponding
channel.
¾ Include Gain setting. The currently set fixed amplification value (by the Gain knob) is included in the display. This can lead to positive values, with the display limited to +6 dB. In
case the option Compressor/Expander is deactivated this option is also not available, therefore grayed out.
¾ Auto Level. Activates the display of the variable amplification of the Auto Leveler. As Auto
Level can both amplify and attenuate the audio signal, depending on its configuration, the
display can show negative (typical gain reduction) as well as positive (above 0 dB, amplification) values.

Snapshots
¾ Do not load Main volume/balance. The values stored in the Snapshot are not loaded for
the Main Out, so the current setting is not changed.
Device Handling
¾ Always init DSP devices with TotalMix FX settings. Used to suppress the mismatch
message after using the unit stand-alone. Settings in the unit are lost.
¾ Count MADI Channels per port. Not available with the Fireface UFX II.
¾ Disable ASIO Direct Monitoring. Disables ASIO Direct Monitoring (ADM) for the Fireface
UFX II within TotalMix FX.
Graphics
¾ Use D2D (Change requires restart). Default on. Can be deactivated to use a compatible
but CPU-taxing graphics mode, in case graphics problems show up.
¾ Brightness Correction. Adjusts the brightness of the TotalMix FX graphics.
Store Setting for (Windows only)
¾ All Users (Restart required). See next chapter.
Special Options
¾ Lock User Interface. Default off. Can be activated to freeze the current mix state. Faders,
buttons and knobs relating to the mix state can not be moved anymore.
25.7.1 Store for Current or All Users (Windows)
TotalMix FX stores all settings, workspaces and snapshots for the current user in:
C.\Users\Username\AppData\Local\TotalMixFX
Current User ensures that when workstations are used by several people they all find their own
settings. In case the settings should be identical or given for any user, TotalMix FX can be
changed to use the All User directory. An admin could even write protect the file lastFirefaceUFXII1.xml, which results in a complete reset to that file’s content whenever TotalMix FX is
restarted. The xml-file is updated on exit, so simply set up TotalMix as desired and exit it (right
mouse click on the symbol in the notification area).

25.8 Settings
The dialog Settings can be opened via the Options menu or directly via F3.
25.8.1 Mixer Page
On the mixer page some typical settings for the mixer operation are set, like Talkback source,
Dim amount when Talkback is active, the stored main volume or the input used for the External
Input function.
Talkback
¾ Input. Selects the input channel of the
Talkback signal (microphone in control
room). Default: None.
¾ Dim. Amount of attenuation of the
signals routed to the Phones in dB.
Listenback
¾ Input. Selects the input channel of the
Listenback signal (microphone in
recording room). Default: None.
¾ Dim. Amount of attenuation of the
signals routed to the Main Out in dB.
Main Out
¾ Recall. User defined listening volume,
activated by the Recall button at the
unit or in TotalMix.
¾ Dim. Amount of attenuation for the
Main Out in dB.
¾ External Input. Selects the stereo
input that replaces the mix signal on
the Main Out when activated. The
volume of the stereo signal is adjusted
by the slider Gain.
PFL Mode
¾ Live Mode, PFL replaces Solo. PFL means Pre Fader Listening. This feature is very useful when operating TotalMix in a live environment, as it allows to quickly listen/monitor any
of the inputs by hitting the Solo button. The monitoring happens on the output set for the
Cue signal via the Assign dialog.

25.8.2 MIDI Page
The MIDI page has four independent settings for up to four MIDI remote controls, using CC
commands or the Mackie Control protocol.
Index
Select one of four settings pages and thus remote controls. Settings are remembered automatically. To activate or deactivate any of the four remote controls check or uncheck ‘In Use’.
MIDI Remote Control
¾ MIDI In. Input where TotalMix receives MIDI Remote data.
¾ MIDI Out. Output where TotalMix sends MIDI Remote data.
¾ Disable MIDI in background. Deactivates MIDI Remote Control as soon as another application is in the focus, or when TotalMix has been minimized.
Mackie Control Options
¾ Enable Protocol Support. When
disabled TM FX will only react on the
Control Change commands of chapter
28.5.
¾ Extender to. Sets the current remote
to be an extender to the main remote.
Both remotes will be shown as one
block and navigate simultaneously.
¾ Map Stereo to 2 Mono Channels.
One fader controls one (mono)
channel. Should be disabled when
stereo channels are used.
¾ Submix Selection in Input/Playback
Row. Enables a selection of the
submix when in first row, without
having to change to the third row first.
However, when using both mono and
stereo channels first and third row
usually do not match anymore, so the
selection often becomes unclear this
way.
¾ Enable full LCD support. Activates
full Mackie Control LCD support with
eight channel names and eight
volume/pan values.
¾ Send User defined Names. Channel
names defined by the user will be sent
to the remote device via MIDI and – if
supported – shown in its display.
¾ Send Level Messages. Activates the transmission of the level meter data. Peak Hold activates the peak hold function as set up for the TotalMix level meters in the preferences.
Note: When MIDI Out is set to NONE then TotalMix FX can still be controlled by Mackie Control
MIDI commands, but the 8-channel block is not marked as remote target.
User's Guide Fireface UFX II © RME

25.8.3 OSC Page
The OSC page has four independent settings for up to four MIDI remote controls via Open
Sound Control (OSC). This is a network based remote protocol that can be used for example by
Apple’s iPad with the app TouchOSC or Lemur to wirelessly remote control TotalMix FX running
on a Mac or Windows computer.
Index
Select one of four settings pages and thus remote controls. Settings are remembered automatically. To activate or deactivate any of the four remote controls check or uncheck ‘In Use’.

¾ IP. Shows the network address of the
computer running TotalMix FX (local
host). This address must be entered on
the remote side.
¾ Host Name. Local computer name.
¾ Port incoming. Must match the remote
entry ‘Port outgoing’. Typical values are
7001 or 8000.
¾ Port outgoing. Must match the remote
entry ‘Port incoming’. Typical values are
9001 or 9000.
Remote Control
¾ IP or Host name. Enter the IP or host
name of the remote control. Please note
that the IP number usually works better
than the host name.
Options
¾ Send Peak Level Data. Activates the
transmission of the peak level meter
data. Peak Hold activates the peak hold
function as set up for the TotalMix level
meters in the preferences.
¾ Lock Remote to submix. When
activated the current remote control can
only modify the submix selected from
the drop-down list. This prevents havoc
in
multi-remote
monitoring
environments.
¾ Number of faders per bank. Available choices are 8 (default), 12, 16, and 24. Note that
when working in underperforming networks, especially wireless, a higher number of faders
might not work as smooth as expected.

25.8.4 Aux Devices
The RME OctaMic XTC is a highly flexible
hi-quality 8-channel microphone, line and
instrument preamp with integrated ADconversion to ADAT, AES/EBU and MADI,
plus 4 channels of DA-conversion for
monitoring. It can be used as universal
front-end for the Fireface UFX II and other
interfaces.
To simplify operation the most important
parameters of the XTC (gain, 48V, phase,
mute, AutoSet) can be controlled directly
from the TotalMix FX input channels. This
special remote control uses MIDI of any
format (DIN, USB, MIDI over MADI).
Device Settings
¾ Digital Channels. Select where the
OctaMic XTC sends its 8 analog
channels to: ADAT channels 1-8 or 916.
¾ Device. At this time only the OctaMic
XTC is supported and can be chosen.
MIDI Settings
¾ MIDI In. Set the currently used MIDI connection to the OctaMic XTC.
¾ MIDI Out. Set the currently used MIDI connection to the OctaMic XTC.
¾ Device ID. Default 0. This setting relates to the current choice in Digital Channels.
When using more than one OctaMic XTC these must have different Device IDs (configuration is
done at the OctaMic XTC). Aux Devices supports to set different Device IDs to the 8-channel
blocks as well. Storing the setting is done automatically when selecting a Device ID. To check
the current assignments toggle the two 8-channel blocks.
The screenshot to the right shows what happens as
soon as the above settings have been confirmed
with OK. The MADI channels show new elements
for phantom power, Inst/PAD, Gain and AutoSet.
Control operates bidirectional, so changing the gain
at the unit will be mirrored in the TotalMix channels.
Changing the gain in TotalMix FX will set the gain in
the unit, which is also shown on the unit’s display.
For the remote to work the XTC’s currently used
MIDI I/Os have to be set to Control. More details are
found in the manual of the OctaMic XTC.

25.9 Hotkeys and Usage
TotalMix FX has many hotkeys and mouse/hotkey combinations to speed up and simplify the
usage. The below description refers to Windows. On Mac substitute Ctrl in the below list with
the command key (u).
The Shift key enables a fine-tuning of the gain with all faders and in the Matrix. On all knobs it
will speed up the setting.
A click on a fader with held down Shift key adds the fader to the temporary fader group.
A click in the fader path with held down Ctrl key will let the fader jump to 0 dB, at the next click
to −∞. Same function: Double click of the mouse.
Clicking on one of the Panorama or Gain knobs with held down Ctrl key lets the knob jump to
center position. Same function: Double click of the mouse.
Clicking on the Panorama knob with held down Shift key lets the knob jump to fully left, with
Shift-Ctrl to fully right.
Clicking on one of the channel settings buttons (slim/normal, Settings, EQ, Dynamics) with held
down Ctrl key lets all channels to the right change their state. For example all panels can be
opened/closed simultaneously.
A double click of the mouse on a knob or its numerical field opens the according Input Value
dialog. The desired value can then be set by keyboard.
Dragging the mouse from a parameter field increases (move up) or decreases (move down) the
value in the field.
Ctrl-N opens the dialog Function Select to open a new TotalMix window.
Ctrl-W opens the dialog File Open of the operating system to load a TotalMix Workspace file.
The key W starts the dialog Workspace Quick Select for a direct selection or storage of up to 30

playback routing, no input mix). See chapter 29 for details.
Store Current state into device. The unit can store up to 6 setups (the current state) in its own
memory. This function is especially useful when working in stand-alone mode.
25.11 Menu Window
Zoom Options 100%, 135%, 200%. Depending on the size of the monitor and the current resolution TotalMix FX might be much too small and the controls too tiny to easily operate them.
Together with the 2 Row mode these options give a lot of different window sizes that suit all
monitors and resolutions currently existing.
Hide Control Strip. Shifts the Control Strip out of the visible area to gain more space for other
elements.
26. The Matrix
26.1 Overview
The mixer window of TotalMix looks and operates similar to mixing desks, as it is based on a
conventional stereo design. The matrix display presents a different method of assigning and
routing channels, based on a single channel or monaural design. The matrix view of the Fireface UFX II has the look and works like a conventional patchbay, adding functionality way beyond comparable hardware and software solutions. While most patchbays will allow you to connect inputs to outputs with just the original level (1:1, or 0 dB, as known from mechanical
patchbays), TotalMix allows you to use a freely definable gain value per crosspoint.
Matrix and TotalMix are different ways of displaying the same processes. Because of this both
views are always fully synchronized. Each change in one view is immediately reflected in the
other view as well.
26.2 Elements of the Matrix View
The visual design of the TotalMix Matrix is mainly determined by the architecture of the Fireface
UFX II system:
¾ Horizontal labels. All hardware outputs
¾ Vertical labels. All hardware inputs. Below are all playback channels.
¾ Green 0.0 dB field. Standard 1:1 routing
¾ Dark grey field with number. Shows the
current gain value as dB
¾ Blue field. This routing is muted
¾ Red field. Phase 180° (inverted)
¾ Dark grey field. No routing.
To maintain overview when the window size has been reduced, the labels are floating. They
won't leave the visible area when scrolling.
78
User's Guide Fireface UFX II © RME
26.3 Operation
Using the Matrix is a breeze. It is very easy to indentify the current crosspoint, because the
outer labels light up in orange according to the mouse position.
¾ If input 1 is to be routed to output 1, use the mouse and click one time on crosspoint In 1 /
AN 1 with held down Ctrl key. Two green 0.0 dB field pop in, another click removes them.
¾ To change the gain (equals the use of a different fader position, see simultaneous display of
the mixer view), drag the mouse up or down, starting from the gain field. The value within the
field changes accordingly. The corresponding fader in the mixer view is moving simultaneously, in case the currently modified routing is visible.
¾ On the right side is the Control Strip from the mixer window, adapted to the Matrix. The button for the temporary fader group is missing as well as all View options, as they don’t make
sense here. Instead the button Mono Mode lets you decide whether all the actions performed in the Matrix are valid for two channels or just one.
The Matrix not always replaces the mixer view, but it significantly enhances the routing capabilities and - more important - is a brilliant way to get a fast overview of all active routings. It shows
you in a glance what's going on. And since the Matrix operates monaural, it is very easy to set
up specific routings with specific gains.
27. Tips and Tricks
27.1 ASIO Direct Monitoring (Windows)
Programs that support ADM (ASIO Direct Monitoring - Samplitude, Sequoia, Cubase, Nuendo
etc.) send control commands to TotalMix. This is directly shown by TotalMix. When a fader is
moved in the ASIO host the corresponding fader in TotalMix will move too. TotalMix reflects all
ADM gain and pan changes in real-time.
But: the faders only move when the currently activated routing (the selected submix) corresponds to the routing in the ASIO host. The Matrix on the other hand will show any change, as it
shows all possible routings in one view.
27.2 Copy a Submix
TotalMix allows you to copy complete submixes to other outputs. In case a complex submix is
need with only a few changes on a different output, the whole submix can be copied to that
output. Right click with the mouse on the original submix output, means Hardware Output. In
the context menu select Copy Submix. Then right click on the new submix output, choose Paste
Submix in the context menu. Now fine tune the submix.
27.3 Doubling the Output Signal (Mirror)
If a mix should be sent out via two (or more) different hardware outputs simply mirror that mix to
any number of other outputs. A right click on the original output brings up the option to
Copy/Mirror <name>. Another right click on the new output, then selecting Mirror of Output
<name> will paste the whole submix and then synchronize it automatically to any future
changes. The outputs now always send out the same signals, but their main volume (fader) and
the EQ and Dynamics settings stay fully independent.
User's Guide Fireface UFX II © RME
79
27.4 Delete a Submix
The easiest and quickest way to delete complex routings is by selection of the according output
channel in the mixer view by a right mouse click, and selection of the menu entry Clear Submix.
As TotalMix FX includes an unlimited undo the delete process can be undone without any problem.
27.5 Copy and Paste everywhere
The above three tips use functions found in the right click context menu available on all channels of the mixer view. These menus are also available in the Matrix, but only directly on the
channel labels. They are self-explanatory and automatically adjust to where the click is performed. The input channels offer Clear, Copy input, Paste the input mix and Paste its FX. On a
playback channel Copy, Paste and Clear the playback mix are available. On an output channel
Copy and Mirror functionality for the current submix and copying of the FX settings is offered.
These options are very advanced and mighty tools to quickly do the impossible. Still there is no
need to fear breaking something, as a simple click (or several) on the Undo button will get you
back to where you started!
27.6 Recording a Submix - Loopback
TotalMix includes an internal loopback function, from the Hardware Outputs to the recording
software. Instead of the signal at the hardware input, the signal at the hardware output is sent to
the record software. This way, submixes can be recorded without an external loopback cable.
Also the playback from a software can be recorded by another software.
The function is activated by the Loopback button in the Settings panel of the Hardware Outputs. In loopback mode, the signal at the hardware input of the corresponding channel is no
longer sent to the recording software, but still passed through to TotalMix. Therefore TotalMix
can be used to route this input signal to any hardware output. Using the subgroup recording, the
input can still be recorded on a different channel.
As each of the 47 stereo hardware outputs can be routed to the record software, and none of
these hardware inputs get lost, TotalMix offers an overall flexibility and performance not rivalled
by any other solution.
The risk of feedbacks, a basic problem of loopback methods, is low, because the feedback can
not happen within the mixer, only when the audio software is switched into monitoring mode.
The block diagram shows how the software's input signal is played back, and fed back from the
Hardware Output to the software input.
80
User's Guide Fireface UFX II © RME
The block diagram also shows why with activated Loopback the EQ of the Hardware Output is
now within the record path. With Loopback active the EQ of the input is not in the record path,
only in the monitoring path, even when the Option DSP – EQ+D for Record is activated.
Recording a Software's playback
In real world application, recording a software's output with another software will show the following problem: The record software tries to open the same playback channel as the playback
software (already active), or the playback one has already opened the input channel which
should be used by the record software.
This problem can easily be solved. First make sure that all rules for proper multi-client operation
are met (not using the same record/playback channels in both programs). Then route the playback signal via TotalMix to a hardware output in the range of the record software, and activate
Loopback for recording.
Mixing several input signals into one record channel
In some cases it is useful to record several sources into only one track. For example when using two microphones recording instruments and loudspeakers, TotalMix' Loopback mode saves
an external mixing desk. Simply route/mix the input signals to the same output (third row), then
redefine this output into a record channel via Loopback. This way any number of input channels
from different sources can be recorded into one single track.
User's Guide Fireface UFX II © RME
81
27.7 MS Processing
The mid/side principle is a special positioning technique for
microphones, which results in a mid signal on one channel and
a side signal on the other channel. This information can be
transformed back into a stereo signal quite easily. The process
sends the monaural mid channel to left and right, the side
channel too, but phase inverted (180°) to the right channel. For
a better understanding: the mid channel represents the function
L+R, while the side channel represents L-R.
During record the monitoring needs to be done in 'conventional' stereo. Therefore TotalMix also
offers the functionality of a M/S-decoder. Activation is done in the Settings panel of the Hardware Input and Software Playback channels via the MS Proc button.
The M/S-Processing automatically operates as M/S encoder or decoder, depending on the
source signal format. When processing a usual stereo signal, all monaural information will be
shifted into the left channel, all stereo information into the right channel. Thus the stereo signal
is M/S encoded. This yields some interesting insights into the mono/stereo contents of modern
music productions. Additionally some very interesting methods of manipulating the stereo base
and generating stereo effects come up, as it is then very easy to process the side channel with
Low Cut, Expander, Compressor or Delay.
The most basic application is the manipulation of the stereo width: a change of the level of the
side channel allows to manipulate the stereo width from mono to stereo up to extended.

28. MIDI Remote Control
28.1 Overview
TotalMix can be remote controlled via MIDI. It is compatible to the widely spread Mackie Control
protocol, so TotalMix can be controlled with all hardware controllers supporting this standard.
Examples are the Mackie Control, Tascam US-2400 or Behringer BCF 2000.
Additionally, the stereo output faders (lowest row) which are set up as Main Out in the Control
Room section can also be controlled by the standard Control Change Volume via MIDI channel 1. With this, the main volume of the Fireface is controllable from nearly any MIDI equipped
hardware device.
MIDI Remote Control always operates in View Submix mode, even when the View Option Free
is currently selected in TotalMix FX.

28.3 Setup
Open the Preferences dialog (menu Options or F3). Select the MIDI Input and MIDI Output port
where your controller is connected to.
When no feedback is needed select NONE as MIDI Output.
Check Enable MIDI Control in the Options menu.
28.4 Operation
The channels being under Mackie MIDI control are indicated by a colour change of the name
field, black turns to brown.
The 8-fader block can be moved horizontally and vertically, in steps of one or eight channels.
Faders can be selected to gang them.
In Submix View mode, the current routing destination (output bus) can be selected via REC Ch.
1 – 8. This equals the selection of a different output channel in the lowest row by a mouse click
when in Submix View. In MIDI operation it is not necessary to jump to the lowest row to perform
this selection. This way even the routing can be easily changed via MIDI.
Full LC Display Support: This option in Preferences (F3) activates complete Mackie Control
LCD support with eight channel names and eight volume/pan values. When Full LC Display
Support is turned off, only a brief information about the first fader of the block (channel and row)
is sent. This brief information is also available on the LED display of the Behringer BCF2000.
Disable MIDI in Background (menu Options, Settings) disables the MIDI control as soon as
another application is in the focus, or in case TotalMix has been minimized. This way the hardware controller will control the main DAW application only, except when TotalMix is in the foreground. Often the DAW application can be set to become inactive in background too, so that
MIDI control is switched between TotalMix and the application automatically when switching
between both applications.
TotalMix also supports the 9th fader of the Mackie Control. This fader (labelled Master) will control the stereo output faders (lowest row) which are set up as Main Out in the Control Room
section.
84
User's Guide Fireface UFX II © RME
28.5 MIDI Control
The hardware output which is set up as Main Out can be controlled by the standard Control
Change Volume via MIDI channel 1. With this, the main volume of the Fireface is controllable
from nearly any MIDI equipped hardware device.
Even if you don't want to control all faders and pans, some buttons are highly desired to be
available in 'hardware'. These are mainly the Talkback and the Dim button, and the monitoring
options (listen to Phones submixes). Fortunately a Mackie Control compatible controller is not
required to control these buttons, as they are steered by simple Note On/Off commands on
MIDI channel 1.
The notes are (hex / decimal / keys):
Dim: 5D / 93 / A 6
Mono: 2A / 42 / #F 2
Talkback: 5E / 94 / #A 6
Recall: 5F / 95 / H 6
Speaker B: 32 / 50 / D3
Cue Main Out: 3E / 62 / D 4
Cue Phones 1: 3F / 63 / #D 4
Cue Phones 2: 40 / 64 / E 4
Cue Phones 3: 41 / 65 / F 4
Cue Phones 4: 42 / 66 / #F 4
Snapshot 1: 36 / 54 / #F 3
Snapshot 2: 37 / 55 / G 3
Snapshot 3: 38 / 56 / #G 3
Snapshot 4: 39 / 57 / A 3
Snapshot 5: 3A / 58 / #A 3
Snapshot 6: 3B / 59 / B 3
Snapshot 7: 3C / 60 / C 4
Snapshot 8: 3D / 61 / #C 4
Trim Gains: 2D / 45 / A 2
Master Mute: 2C / 44 / #G 2
Master Solo: 2B / 43 / G 2
Furthermore all faders of all three rows can be controlled via simple Control Change commands. The format for the Control Change commands is:
Bx yy zz
x = MIDI channel
yy = control number
zz = value
The first row in TotalMix is addressed by MIDI channels 1 up to 4, the middle row by channels 5
up to 8 and the bottom row by channels 9 up to 12.
16 Controller numbers are used: 102 up to 117 (= hex 66 to 75). With these 16 Controllers (=
faders) and 4 MIDI channels each per row, up to 64 faders can be controlled per row (as required by the HDSPe MADI).
User's Guide Fireface UFX II © RME
85
Examples for sending MIDI strings:
- Set input 1 to 0 dB: B0 66 68
- Set input 17 to maximum attenuation: B1 66 0
- Set playback 1 to maximum: B4 66 7F
- Set Output 16 to 0 dB: B8 75 68
Note: Sending MIDI strings requires to use programmer's logic for the MIDI channel, starting
with 0 for channel 1 and ending with 15 for channel 16.
Further functions:
- Trim Gains On: BC 66 xx (BC = MIDI channel 13, xx = any value)
- Trim Gains Off: BC 66 xx or select a submix
Select submix (fader) in third row:
- channel 1/2: BC 68/69 xx
- channel 3/4: BC 6A/6B xx
etc.
Input Gain control is available via CC9, value range as the gain itself (up to 65). The MIDI
channel determines the controlled channel, from 1 to 16 (UFX: 9 to 12). For this to work, Enable
MIDI Control in the Options menu has to be activated.
The Reverb and Echo User Presets can be changed via MIDI CC: B2 0C nn for Reverb preset
1 to 16, B3 0C nn for Echo preset 1 to 16
28.6 Stand-Alone MIDI Control
When not connected to a computer, the Fireface UFX II can be controlled directly via MIDI. The
stand-alone MIDI control mode is activated in the unit’s menu Options, HW Options/Diagnosis, Standalone MIDI.
Note: When not needed the stand-alone MIDI operation should not be active, as the unit will
react on MIDI notes after power-on, and will also send MIDI notes.
Control is performed via both the Mackie Control protocol and some standard MIDI functions
(see below). In stand-alone mode not all functions known from TotalMix are available, because
some of them aren't hardware, but software routines. Functions like Talkback, Mono, Solo, relative ganging of the faders, Monitor Main and Monitor Phones are realized by complex software
code, therefore not available in stand-alone MIDI control operation.
Still many functions, and especially the most important functions to control the Fireface UFX II,
are implemented in hardware, thus available also in stand-alone mode:
•
•
•
•
•
All faders and pans of the first and third row
Mute of the input signal per channel
Ganging via 'Select'
Choice of the routing destination, i.e. the current submix
Sending of LED and display data to the MIDI controller
The second row (software playback) is skipped. The Fireface UFX II sends display data as brief
information, enabling an easy navigation through lines and rows. Other data like PAN and miscellaneous status LEDs are supported as well.
86
User's Guide Fireface UFX II © RME
In stand-alone mode the unit always operates in View Submix mode. Only this way the routing
destination can be changed, and several mixdowns/submixes can be set up quickly and easily.
If the current TotalMix setup is transferred into the Fireface via 'Flash current mixer state', the
currently selected submix output is also pre-configured in the hardware for stand-alone MIDI
remote operation.
Mackie Control Protocol
The stand-alone operation supports the following Mackie Control surface elements*:

Loading the Setups stored in the device enables a quick configuration change of the UFX. With
this any possible operation state can be activated by the push of a button at any time.
User's Guide Fireface UFX II © RME
87
28.7 Loopback Detection
The Mackie Control protocol requires feedback of the received commands, back to the hardware controller. So usually TotalMix will be set up with both a MIDI input and MIDI output. Unfortunately any small error in wiring and setup will cause a MIDI feedback loop here, which then
completely blocks the computer (the CPU).
To prevent the computer from freezing, TotalMix sends a special MIDI note every 0.5 seconds
to its MIDI output. As soon as it detects this special note at the input, the MIDI functionality is
disabled. After fixing the loopback, check Enable MIDI Control under Options to reactivate the
TotalMix MIDI.
28.8 OSC (Open Sound Control)
Besides simple MIDI notes, the Mackie Protocol and Control Change commands, TotalMix FX
can also be controlled by the Open Sound Control, OSC. For details on setup and usage see
chapter 25.8.3.
An OSC implementation chart can be downloaded from the RME website:
http://www.rme-audio.de/download/osc_table_totalmix.zip
RME offers a free iPad template for the iOS app TouchOSC (by Hexler, available in the Apple
App-Store):
http://www.rme-audio.de/download/tosc_tm_ipad_template.zip
The RME forum hosts further information, more templates (iPhone…) and lots of useful user
feedback.
29. DAW Mode
Users that work exclusively with their DAW software, and don’t want to use TotalMix FX for
additional routing tasks, need a way to be sure that TotalMix FX currently doesn’t change the
DAW’s routing. While Reset Mix can do so, those users would be better served with a very simple surface that offers the interface’s hardware controls (gain, phantom control, instrument…),
but guarantees a straight 1:1 routing for all playback channels, and has no hardware monitoring
of the input channels (which is then done by the DAW software).
For such cases TotalMix FX includes an alternative operating mode. It can be booted into the
so called DAW mode. This simplified interface is for anyone performing all monitoring and routing within the DAW. The DAW mode restarts TM FX into a light version with just two rows, no
playback row, and no mixing faders in the input row. Routing is 1:1 only. Just the hardware controls (if existing) and hardware output levels are available.
To change the current mode go to the menu, Options, and click on Operational Mode. Choices
are Full Mode (default, mixer active, all routing options available), and Digital Audio Workstation
Mode (straight playback routing, no input mix).
Several useful, advanced features are still available in TotalMix FX in DAW mode:
¾ Talkback, External Input
¾ Phones definition and handling with Talkback
¾ Speaker A / B
¾ All FX (EQ, Dynamics, Echo, Reverb)
¾ Mute and Solo
¾ Cue / PFL

Fireface UFX II
Class Compliant Mode
User's Guide Fireface UFX II © RME
89
30. General
The Fireface UFX II operates in two different modes: driver-based USB2 and Class Compliant. The latter describes a standard that is natively supported by operating systems like Windows, Mac OS X and Linux. No proprietary drivers are required, the device will be directly recognized when the CC firmware is loaded. The natively available features will be limited in comparison to those provided by the RME driver for the UFX II. For example there will be no hardware settings, no (Total) Mix and no settings for the effects. However, on the iPad (iOS) the
UFX II can be fully controlled by the optional app TotalMix FX for iPad.
The Class Compliant mode can be activated and deactivated directly at the unit, as long as it is
not connected to a Mac or PC: SETUP/REV, Options, Hardware/Diagnosis, Interface Mode,
CC.
Neither Windows nor Mac Class Compliant support is relevant, though, since there are dedicated and matured drivers for both OS X and Windows, which provide ALL the device's features
at lowest latencies. The main reason for implementing Class Compliant mode was to allow connecting the UFX+ to an Apple iPad®!
The UFX II provides the iPad with the professional analog I/O connections it lacks. Superb microphone preamps with EQ, dynamics, even with the AutoSet feature, in addition to professional balanced line outputs, and hi-power headphone outputs which also excel with high impedance phones. Plus level and gain adjustments, AES and ADAT I/O, reverb, echo, zero latency monitoring, digitally via USB, without any limitation in quality, at up to 96 kHz and 24 bit.
And of course a Sysex-capable double MIDI I/O.
DURec, the direct USB recording on USB memory stick or portable external hard drive, is also
available in Class Compliant mode. Especially in regard to recording on the iPad it is not only a
world-wide unique and extraordinary feature, it also proves to be something you don’t want to
miss in real-world usage.
TotalMix FX for iPad also provides full support for the optional ARC USB, an Advanced Remote
Control specifically for the UFX+, making operation and handling of the iPad DAW even more
easy and comfortable.

32. Operation
Activation of the Class Compliant mode
Remove USB cable from the UFX II. Press SETUP/REV. Turn encoder 1 until Options appears
in the display. Turn encoder 2 until Hardware/Diagnosis appears. Push encoder 2 several times
to select the entry CC Mode. Turn encoder 2 to activate CC mode. The UFX II reboots, after
which it will be in Class Compliant mode. The green CC state LED will light up as soon as a
USB connection is detected.
The option CC Routing offers two different routings of the playback signals. See chapter 35.
Connect the USB cable to the UFX II and the Lightning to USB adapter. Start the iPhone/iPad
and plug-in the adapter. If everything works as expected, the unit will enter CC host mode, indicated by the green CC LED turning on. Audio playback will automatically be performed by the
UFX+, using analog outputs 1/2 and the phones outputs 9/10, 11/12 (with routing option Phones
activated).
Apps that support MIDI and are ready for Core MIDI will offer dialogs to select the desired UFX+
MIDI inputs and outputs.
32.1 Useful hints
If the unit is not in CC mode, the iPhone/iPad will detect an
incompatible USB device, and display a message saying
“Cannot Use Device – The connected USB device is not
supported”.
No sound: Incorrect output gain settings, see chapter 35. Note that the iPhone/iPad volume
control is inactive during USB operation.
If the unit does not enter Host mode: Remove and reconnect the Connection Kit.
Since 2016 Apple offers another version of the USB to Lightning Adapter, called Lightning to
USB 3 Camera Adapter. It has an additional Lightning port for power supply that charges the
iPhone/iPad even when used with the UFX II.
User's Guide Fireface UFX II © RME
91
32.2 Class Compliant Mode under Windows and Mac OS X
Windows does not support USB Audio 2.0 (UAC 2). The UFX II will be detected, but automatic
driver installation will fail. This is important to remember. Connecting the UFX II to the PC after
having it used with the iPhone/iPad one might forget that it is still in CC mode.
Mac OS X supports USB Audio
2.0, even with more than 2
channels. The UFX II offers 24
input and 24 output channels at
up to 96 kHz. It is shown as
“Fireface UFX II (xxxxxxxx)“ in
the Audio MIDI Setup, in both
normal and CC mode. In CC
mode the USB Settings will
vanish from the Dock, and
TotalMix will – if at all – show a
‘disconnected’ UFX II.
The Audio window in the Audio
MIDI Setup lists two available
modes: 12 channels and 24
channels. The sample rate
shown here is the one set at the
UFX II.
With 12 channels chosen up to 192 kHz sample rate can be used. Under iOS 192 kHz is not
possible, as there exists no way to select the second Alternate Setting on the record side. iOS
and all apps always use the first setting, 24 channels, which limits the sample rate for record
and playback to 96 kHz.
33. Supported Inputs and Outputs
In Mac OS X, either the first 12 or 24 channels will work, depending on the choice in the Audio
MIDI Setup. In both cases the playback signal of channels 1/2 can be copied to other outputs.
When connected to an iPad, the analog mic/line input 1 works with mono apps, inputs 1 and 2
with stereo apps (both dual mono and stereo), and up to 8 inputs with 8-channel applications
like MultiTrack DAW and Music Studio. Garage Band supports all inputs, but only two at a time.
Auria and Cubasis can record all 24 inputs simultaneously.
Playback will use the rear-side analog outputs 1 and 2, or even more channels if the app supports such operation. The UFX+ can optionally copy the playback channels 1/2 to outputs 9/10
and 11/12, for easier monitoring (CC routing Phones). The current routing can easily be
checked and verified with the level meter display. All outputs can be processed independently
(volume, EQ, dynamics, FX return).
Configuring the UFX II is ideally done via the app TotalMix FX for iPad, otherwise by loading
Setups. These are written into the unit while operated with PC/Mac via TotalMix FX, also storing
control clock mode master or AutoSync and the current sample rate. Using RME’s iPad app the
routing Phones is automatically disabled as all routing is now controlled by the app.
The UFX II (and with it the iPhone/iPad) will be synchronized to an external digital sample rate if
there is a valid digital input signal. With a wrong sample rate heavy audio noise will occur. Without an AES/SPDIF or ADAT input signal the UFX II enters master mode and uses the sample
rate set by Mac OS X or iOS (the app in use).
92
User's Guide Fireface UFX II © RME
While the MIDI I/Os will send and receive Sysex messages, not all apps are ready to do this.
The app Midi Tool Box can be used to verify that the UFX II is working correctly, and the problem lies somewhere else.
34. Front panel operation
The front panel operation is identical to the one under Windows and OS X, or standalone operation. The display therefore gives the usual easy access to all features and offers a quick editing
of: input gains, playback levels, routing and monitoring, echo, reverb, EQ, dynamics, sample
rate, status of the optical output (ADAT/SPDIF), and much more.
35. Audio Routing and Processing
In Class Compliant mode, the UFX II features operation very similar to normal operation with
TotalMix FX, with two major differences:
¾
¾
There is no second TotalMix row (no software playback channels), hence no individual
routing or mixing of playback channels. These will always be connected either straight to the
physical outputs (CC-Routing 24 Ch.), or have an additional signal copy from 1/2 to 9/10 and
11/12 (CC-Routing Phones), making the headphone outputs work.
The input effects EQ/Dyn will always be active in the recording path
The UFX II can be pre-configured for CC mode via TotalMix FX under Windows/Mac by saving
up to 6 configurations into its setup memory, see next chapter.
The input signal will pass through all activated functions of the TM FX input channel, namely
settings, EQ, and Dynamics, and is then sent to the iPhone/iPad. Like under Windows and Mac,
the input fader setting controls direct monitoring to the specified outputs. The FX send control
for echo/reverb is also active.
!
As in normal TotalMix FX use, the options Stereo Width, MS Proc and Phase L/R are NOT
within the recording path, but in the monitor path. This is technically determined and can not
be changed.
The iPhone/iPad output signal passes through all activated functions of the TM FX hardware
outputs, namely settings, EQ, and dynamics. The third row’s fader sets the output level.
!
Control Room Section settings are inactive. Configuring the Phones output is done by
output channel 9/10 and 11/12.
Both modes can be activated at any time and do not influence the mixer state loaded via the
Setups, as they only influence the playback routing. The current routing can easily be checked
and verified with the level meter display.
User's Guide Fireface UFX II © RME
93
36. Setups
TotalMix FX can transfer all current settings to the device (Options/Store Current State into
Device). There are six memory slots (Setups) available. An example:
¾ Inputs with no processing, gain set to +30 dB and phantom power active. Outputs without
processing, faders for 1/2 set to 0 dB, 9/10 at – 20 dB, clock mode master, saved in Setup 1.
¾ Inputs with Compressor, Factory Preset Mix Limiter (digital overload protection), gain set to
+30 dB, no phantom power, outputs 1/2 with EQ (factory preset Modern Bass Treble),
outputs 9/10 with EQ (factory preset Cheap Phones Compensation), faders for 1/2 at 0 dB,
9/10 at -20dB, clock mode AutoSync, saved in Setup 2.
Via the menu SETUP/REV, Setups, one can switch between setups 1 and 2 at any time, alternating between entirely different configurations. Further examples would be activating reverb/echo, or temporary monitoring of the input signal. Very comfortable is the use of the Advanced Remote USB, as its buttons can load the Setups 1 to 6 directly
On the iPad the optional app TotalMix FX for iPad gives full control of all functions and parameters in real-time and with full overview, similar to working under Windows and Mac.

95
37. Direct USB Recording
37.1 Overview
The Fireface UFX II can record and playback up to 60 channels of audio via the USB port on
the front panel. This functionality is provided by the internal DSP and is therefore independent
from a Windows or Mac computer connected via USB.
As all settings are also available directly at the unit it is possible to even record a whole live
concert completely without a computer. Music that was copied onto the stick earlier can be
played back anytime on any outputs.
The following chapters explain features, capabilities, but also restrictions of this functionality.
37.2 Operation
In TotalMix FX the DURecorder panel controls the record and playback functions. The configuration of record/playback is stored in the workspace, therefore identical in all eight Snapshots.
File selection. Multi-purpose dialog. Displays detailed information on current
USB media conditions. No Media (no media recognized), Initializing (Medium
is currently initialized), FS Error (File System Error, no FAT32), No Files (no
audio files found).
In case the media contains audio material, files can be selected from the file
dialog box after a click on the arrow to the right.
Clicking on the red button will initiate recording, and a new file will be created
immediately, with an increment file number according to present files.
Info. Opens a dialog with information about the selected file: file name,
number of channels, sample rate, length (time), free memory.
Delete. Offers direct erasure of the current file. After deletion, the media is read again (Initializing) which can take some time on larger hard drives. Deleting further files is possible even while
the initialization is still in progress.
Status Panel. The overview window shows current position or length of the file, free memory,
current USB Load and Errors.
Position display. The position of the knob shows the current playback position
within the file. The knob, and with it the playback position, can also be changed by
dragging it with the mouse.
Transport bar. Stop, Play/Pause and Record. Two clicks on Stop cause a jump to
the beginning of the file.
Record View. Switches from Mixer View to Record View. In Record View Mute and
Solo buttons in first and third row are replaced by Play and Record (Arm) buttons.
A click on the Playback button opens a dialog to assign channels. A flashing
playback button indicates playback channels have been selected that are not found
in the played back file. A playback is not only possible at the outputs but also at the
mixer input. This way, signals can also be processed with Echo/Reverb and mixed
with any other signal to any output
Note: The level meters only show the DURec playback signal when in Post FX mode.
96
User's Guide Fireface UFX II © RME
The Record buttons behave in a similar way to other buttons in TotalMix: Activation/deactivation
of all channels to the right by Ctrl + mouse click, flashing buttons when the maximum number of
channels has been exceeded after changing the sample rate. When loading a different workspace during ongoing recording and playback, the configuration of record and playback is not
updated or changed.
The display of the Fireface UFX II brings up the Record/Playback menu automatically when a
storage medium is connected and recognized, or after pushing the REC/PLAY button.
File. Name of the currently selected file.
Status. This line changes its content depending on the current
operation: information on the selected file, the ongoing or just
completed recording: xx channels selected (number of channels
armed for recording), SR xx kHz (sample rate), USB xx%, x Err
(USB Load and number of errors).
Time. Length of the recording or current playback position.
When selecting the record button at the unit the medium’s
remaining total record time is shown. Due to the limitation to 100
files the actual recording time may be shorter. In Stop and
Playback mode turning encoder 2 allows to change the current playback position.
Transport Bar. Turning encoder 2 moves the cursor over Del (Delete), Record, Play/Pause and
Stop. The selected function is initiated by pressing encoder 2.
Turning encoder 1 brings up the Rec/Play Settings with subpages USB Media, Record, Playback and Time & Date.
USB Media.
DURec/Partition. The Direct USB Recording function can be
switched off completely. This reduces the DSP load a bit, which
then raises the number of possible effects in TotalMix FX. Turn
encoder 2 to select Off. Default is1, which means both DURec
enabled and the first partition found on the USB media will be
used. On some media it will be necessary to use partition 2 or up.
Capacity. Storage size of the media.
Free. Free space on the media.
Record.
Remain (Rec.). The medium’s remaining total record time
Free. Free space on the media.
Max R/W Time. The time needed for the read or write operation.
Details see chapter 37.5.
User's Guide Fireface UFX II © RME
97
Playback.
Remain (File). Remaining play time of the current file.
Next. Shows and allows to select the next file to be played.
Play Mode. Choices are single (stop after the current file), UFX
(play all consecutive files that belong to one recording session),
and cont. (continuous, plays all files consecutively).
During playback it is possible to pre-select the next to be played
file by navigating to the Next line and select any of the available
files. Single mode is extended by the next file and will stop after
that, unless another file had been selected again.
Continuous plays all existing files consecutively. Next can still be used to re-play or interactively
change the playlist by selecting any file during playback.
UFX plays all files following the incremental UFX name scheme (UFX01_00.wav,
UFX01_01.wav, UFX01_02.wav etc). This feature can be used to build playlists by renaming
other wav files to the same name scheme, then playing them via play mode UFX from a thumb
drive.
Time & Date.
The UFX+ has a real-time clock that is set automatically when
connecting the UFX+ to a computer with TotalMix FX running.
The clock is used to timestamp the recorded DURec files with the
current time and date values (file attribute). Time & Date can also
be set manually using this easy to use dialog.
37.3 Limitations and Important Notes
The media must be formatted as FAT32, primary type. Logical partitions are not supported.
With volumes having more than one partition, a different partition than default partition 1 can be
selected in Rec/Play Settings, USB Media.
A recording is always stopped when the sample rate changes.
Changing the record configuration (armed channels) is not possible during an ongoing recording. Channels are recorded without placeholders and without labelling, in straight ascending order. For a playback on the exact same channels, the playback channels have to be selected accordingly in TM FX or the unit.
The recording is done at the current sample rate as 24 bit WAV file. A file can be up to 2 GB in
size and includes all (up to 60) channels in interleaved format. The filename is UFX01_00.wav.
After reaching the 2 GB limit a new file is automatically written, with an incremental file number
(UFX01_01.wav). The UFX will write up to 100 files consecutively (UFX_01_99.wav). After that,
a new recording has to be started (UFX02_00.wav).
At a sample rate of 48 kHz, up to 60 channels (inputs and outputs), at 96 kHz 38 channels, at
192 kHz 19 channels can be selected. The actual number of channels that can be used errorfree depends on the media, see chapter 37.5.
98
User's Guide Fireface UFX II © RME
The playback from a storage device does not change the current sample rate. To match pitch
and speed, the sample rate has to be set manually to the correct value. Playback can be assigned to multiple outputs.
The UFX can play back externally recorded WAV files, as long as these have 16 or 24 bit resolution.
The recording signal is taken before EQ and Dynamics, on both inputs and outputs. To record
with EQ/Dyn, activate REC on an output and route a signal processed by the input EQ/Dyn to
that output. The insert point of playback is at the same place.
The block diagram shows the signal flow for various situations, depending on the state of Loopback, EQ for Record and Play active. In the diagram Loopback and EQ are switched to off, but
a playback is active in the input.
Some extra notes that are worth to be pointed out again:
• The signal recorded by audio software is usually that from the input. But when the option
DSP – EQ for Record has been activated in the Settings dialog the software receives the
Play input signal – as soon as a playback is started from the USB device.
• On an output Echo/Reverb gets recorded. To add Echo/Reverb to a playback the playback
must be assigned to an input.
• A playback via USB can not be processed and immediately recorded again via DURec. While the block diagram seems to present such functionality please remember that DURec can
do only one thing at a time – record or playback.

37.4 Multichannel WAV File Batch Processor
To avoid any kind of performance problems the recording of all channels is done into a single
multi-channel interleaved file, guaranteeing highest streaming performance with any media.
Most digital audio workstations can import such multi-channel wave files directly into their projects. Also there already exist some free tools to split those multi-channel files into standard
stereo or single channel files. The need for the special RME tool arises from the fact that fully
compatible wave files can not be bigger than 2 GByte. With higher track counts and longer recording times this limit is quickly exceeded. The DURec process of the Fireface UFX II therefore
writes multiple consecutive files of 2 GByte each. Importing these files into typical DAWs requires the user to adjust and align the content of each file to the previous one.
RME’s Multichannel WAV File Batch Processor offers the easiest way to combine and split
those multichannel interleaved files into single or dual channel files. The content of consecutive
files is automatically combined into a single file. In the rare case that these again exceed the 2
GB limit the tool automatically writes RF64 files. The Mac version can also write CAF (Core
Audio Format) files.
The RME tool can also perform multiple conversions of different recordings. Once all the single
tasks are set up the software will process them one after the other automatically.
The free software is available for Windows and Mac OS X and can be downloaded from the
RME website, www.rme-audio.com, section Downloads / Software, or installed from the
RME Driver CD.

37.5 Technical Background
Compared to a usual computer, the front USB port of the UFX+ has a limited buffer to compensate for interruptions to the write process. Unfortunately, these occur quite often with USB
thumb drives, and sometimes are of an astonishing duration. The effect of the buffer depends
on the amount of data to be transmitted, which is the combination of sample rate and channel
count. The higher the data rate, the shorter the available buffer time. When a medium causes a
pause that is longer than the buffer time, data is lost.
Information on the performance of the record media
To determine the highest record channel count of a hard drive or USB thumb drive the UFX II
displays several values. On the page Record/Playback:
USB Load: should exceed 80% only for a short time.
Errors: Each single error means a buffer with a bigger block of samples has been lost. Although that is not always audible only a display of 0 is acceptable.
On the page USB Media, Record:
Max R/W Time (Read/Write Time): This constantly updated value is the quickest way to identify
slow media that suffer from interruptions of the write process. Hard drives often show values in
the range of 100 ms, while thumb drives can reach more than 800 (!) ms.
Checking the performance of the record media
Every USB stick can be used for recording – but most are too slow to record more than a few
channels. While write rates higher than 10 MB/s are rare, simultaneous quick processing of
recorded data is even less frequently found.
To determine the maximum channel count of a medium, activate all 76 record channels at a
sample rate of 48 kHz. This configuration causes the highest data throughput (10.7 MB/s) with
the smallest internal buffer. Most hard drives manage an error-free recording until the drive is
full. In case the UFX+ shows errors, reduce the number of channels step by step until no errors
are shown anymore.
Note: 15 channels at 192 kHz equal 30 channels at 96 kHz and 60 channels at 48 kHz (8.4
MB/s).
A more realistic example is the recording of all 30 inputs and of two submixes (34 channels) at
48 kHz. With 4.8 MB/s data transfer better USB sticks will handle this task without any problem.
The display of USB Load, Max Write Time and errors quickly reveals where the limit of the particular thumb drive lies.
Note: Playback is usually not affected by the mentioned performance problems.
An example of a USB flash drive that handles the maximum transfer bandwidth error-free is the
SanDisk Extreme Memory, available in 16, 32 and 64 GByte. It worked without write pausing
under USB 2, and is lightning fast under USB 3 as well.

39. Technical Background
39.1 Lock and SyncCheck
Digital signals consist of a carrier and the data. If a digital signal is applied to an input, the receiver has to synchronize to the carrier clock in order to read the data correctly. To achieve this,
the receiver uses a PLL (Phase Locked Loop). As soon as the receiver meets the exact frequency of the incoming signal, it is locked. This Lock state remains even with small changes of
the frequency, because the PLL tracks the receiver's frequency.
If an ADAT or SPDIF signal is applied to the Fireface UFX II, the corresponding input LED starts
flashing. The unit indicates LOCK, i. e. a valid input signal (in case the signal is also in sync, the
LED is constantly lit, see below).
Unfortunately, LOCK does not necessarily mean that the received signal is correct with respect
to the clock which processes the read out of the embedded data. Example: The Fireface is set
to 44.1 kHz internally (clock mode Master), and a mixing desk with ADAT output is connected to
input ADAT1. The corresponding LED will show LOCK immediately, but usually the mixing
desk's sample rate is generated internally (also Master), and thus slightly higher or lower than
the Fireface's internal sample rate. Result: When reading out the data, there will frequently be
read errors that cause clicks and drop outs.
Also when using multiple inputs, a simple LOCK is not sufficient. The above described problem
can be solved elegantly by setting the Fireface from Master to AutoSync (its internal clock will
then be the clock delivered by the mixing desk). But in case another, un-synchronous device is
connected, there will again be a slight difference in the sample rate, and therefore clicks and
drop outs.
In order to display those problems optically at the device, the Fireface includes SyncCheck. It
checks all clocks used for synchronicity. If they are not synchronous to each other (i. e. absolutely identical), the SYNC LED of the asynchronous input flashes. In case they are completely
synchronous, all LEDs are constantly lit. In example 1 it would have been obvious that the LED
ADAT 1 kept on flashing after connecting the mixing desk.
In practice, SyncCheck allows for a quick overview of the correct configuration of all digital devices. So one of the most difficult and error-prone topics of the digital studio world finally becomes easy to handle.
The same information is presented in the Fireface's Settings dialog. In the status display the
state of all clocks is decoded and shown as simple text (No Lock, Lock, Sync).

39.2 Latency and Monitoring
The term Zero Latency Monitoring has been introduced by RME in 1998 for the DIGI96 series
of audio cards. It stands for the ability to pass-through the computer's input signal at the interface directly to the output. Since then, the idea behind has become one of the most important
features of modern hard disk recording. In the year 2000, RME published two ground-breaking
Tech Infos on the topics Low Latency Background, which are still up-to-date: Monitoring, ZLM
and ASIO, and Buffer and Latency Jitter, both found on the RME website.
How much Zero is Zero?
From a technical view there is no zero. Even the analog pass-through is subject to phase errors, equalling a delay between input and output. However, delays below certain values can
subjectively be claimed to be a zero-latency. This applies to analog routing and mixing, and in
our opinion also to RME's Zero Latency Monitoring. The term describes the digital path of the
audio data from the input of the interface to its output. The digital receiver of the Fireface UFX II
can't operate un-buffered, and together with TotalMix and the output via the transmitter, it
causes a typical delay of 3 samples. At 44.1 kHz this equals about 68 µs (0.000068 s), at 192
kHz only 15 µs. The delay is valid for ADAT and SPDIF in the same way.
Oversampling
While the delays of digital interfaces can be disregarded altogether, the analog inputs and outputs do cause a significant delay. Modern converter chips operate with 64 or 128 times oversampling plus digital filtering, in order to move the error-prone analog filters away from the audible frequency range as far as possible. This typically generates a delay of one millisecond. A
playback and re-record of the same signal via DA and AD (loopback) then causes an offset of
the newly recorded track of about 2 ms.
Low Latency!
The Fireface UFX II uses AD and DA converters with an innovative digital filter, causing a delay
of only a few samples. With 13 samples AD and 7 samples DA the delay caused by the conversion is only about a quarter of previous generations. The exact delays of the UFX+ converters
are:

Buffer Size (Latency)
Windows: This option found in the Settings dialog defines the size of the buffers for the audio
data used in ASIO and WDM (see chapter 9).
Mac OS X: The buffer size is defined within the application. Only some do not offer any setting.
For example iTunes is fixed to 512 samples.
General: A setting of 64 samples at 44.1 kHz causes a latency of 1.5 ms, for record and playback each. But when performing a digital loopback test no latency/offset can be detected. The
reason is that the software naturally knows the size of the buffers, therefore is able to position
the newly recorded data at a place equalling a latency-free system.
User's Guide Fireface UFX II © RME
109
AD/DA Offset under ASIO and OS X: ASIO (Windows) and Core Audio (Mac OS X) allow for the
signalling of an offset value to correct buffer independent delays, like AD- and DA-conversion or
the Safety Buffer described below. An analog loopback test will then show no offset, because
the application shifts the recorded data accordingly. Because in real world operation analog
record and playback is unavoidable, the drivers include an offset value matching the Fireface's
converter delays.
Therefore, in a digital loopback test a negative offset of about 3 ms occurs. This is no real
problem, because this way of working is seldom, and usually the offset can be compensated
manually within the application. Additionally, keep in mind that even when using the digital I/Os
usually at some place an AD- and DA-conversion is involved (no sound without...).
Note: Cubase and Nuendo display the latency values signalled from the driver separately for
record and playback. The values do not exactly equal the buffer size (for example 3 ms at 128
samples), instead a higher value is shown, including the time needed for the AD/DA-conversion.
Playback shows an even higher value – see Safety Buffer.
Safety Buffer
An additional small safety buffer on the playback side has proven to be very efficient and useful.
It is therefore implemented in all RME interfaces. Under Windows the Fireface UFX II uses a
fixed additional buffer of 32 samples with USB and 64 samples with FireWire, under Mac 32
samples, which is added to the current buffer size. The main advantage is the ability to use
lowest latency at highest CPU loads. Furthermore, the fixed buffer does not add to the latency
jitter (see Tech Info), the subjective timing is extraordinary.
Core Audio's Safety Offset
Under OS X, every audio interface has to use a so called Safety Offset on record and playback,
otherwise Core Audio won't operate click-free. The Fireface uses a Safety Offset of 16 samples
with USB and 32 samples with FireWire. This offset is signalled to the system, and the software
can calculate and display the total latency of buffer size plus AD/DA offset plus 2 x Safety Offset
plus Safety Buffer for the current sample rate.
39.3 USB Audio
USB audio is in several ways different from PCI based audio interfaces. A good performance
and click-free operation at a low buffer size are indeed possible on current computers. However, using older computers a simple stereo playback will begin to cause a CPU load of more
than 30%.
A computer blocked for a short time – no matter if ASIO or WDM – will lose one or more data
packets. Such problems can only be solved by increasing the buffer size (latency).
The Fireface features a unique data
checking, detecting errors during
transmission via USB and displaying
them in the Settings dialog.
Additionally the Fireface provides a special mechanism to continue recording and playback in
case of drop-outs, and to correct the sample position in real-time.
Best USB 2 performance is achieved by connecting the UFX II to its own bus, which should be
no big problem as most USB 2.0 interfaces are a double bus design. A check in the Device
Manager can be done as follows:
Connect the UFX II to a USB 2 port
¾ Start the Device Manager, View set to Devices by Connection
¾ Select ACPI x86-based PC, Microsoft ACPI-Compliant System, expand PCI Bus
110
User's Guide Fireface UFX II © RME
This branch normally includes two entries of a USB2 Enhanced Host Controller. A USB Root
Hub can be seen, which then connects all USB devices, including the UFX II. By reconnecting
to a different port this view shows at which of the two controllers the UFX II is connected. With
multiple devices it can be checked if they are connected to the same controller.
Furthermore this information can be used to operate an external USB drive without disturbing
the UFX II, by simply connecting the drive to the other controller.
Especially with notebooks it can happen that all internal devices and all the sockets/ports are
connected to the same controller, with the second controller not used at all. In that case all devices have to use the same bus and will interfere with each other.
39.4 DS - Double Speed
Sample rates above 48 kHz were not always taken for granted, and are still not widely used
because of the CD format (44.1 kHz) dominating everything. Before 1998 there were no receiver/transmitter circuits available that could receive or transmit more than 48 kHz. Therefore a
work-around was used: instead of two channels, one AES line only carries one channel, whose
odd and even samples are being distributed to the former left and right channels. By this, you
get the double amount of data, i. e. also double sample rate. Of course in order to transmit a
stereo signal two AES/EBU ports are necessary then.
This transmission mode is called Double Wire in the professional studio world, and is also
known as S/MUX (Sample Multiplexing) in connection with the multichannel ADAT format.
Because the ADAT interface does not allow for sampling frequencies above 48 kHz (a limitation
of the interface hardware), the Fireface UFX II automatically uses Sample Multiplexing in DS
mode. One channel's data is distributed to two channels. As the transmission of double rate
signals is done at standard sample rate (Single Speed), the ADAT outputs still deliver a 44.1
kHz or 48 kHz carrier.
39.5 QS – Quad Speed
Due to the small number of available devices that use sample rates up to 192 kHz, but even
more due to a missing real world application (CD...), Quad Speed has had no broad success.
An implementation of the ADAT format as double S/MUX (S/MUX4) results in only two channels
per optical output. Devices using this method are few.
In earlier times the transmission of 192 kHz had not been possible via Single Wire, so once
again sample multiplexing was used: instead of two channels, one AES line transmits only one
half of a channel. A transmission of one channel requires two AES/EBU lines, stereo requires
even four. This transmission mode is being called Quad Wire in the professional studio world.
Because the ADAT interface does not allow for sampling frequencies above 48 kHz (a limitation
of the interface hardware), the Fireface UFX II automatically uses Sample Multiplexing in QS
mode. One channel's data is distributed to four channels. As the transmission of quad rate signals is done at standard sample rate (Single Speed), the ADAT outputs still deliver a 44.1 kHz
or 48 kHz carrier.

39.6 Noise level in DS / QS Mode
The outstanding signal to noise ratio of the Fireface UFX II AD-converters can be verified even
without expensive test equipment, by using record level meters of various software. But when
activating the DS and QS mode, the displayed noise level will rise from -113 dB to -105 dB at 96
kHz, and –79 dB at 192 kHz. This is not a failure. The software measures the noise of the whole
frequency range, at 96 kHz from 0 Hz to 48 kHz (RMS unweighted), at 192 kHz from 0 Hz to 96
kHz.
When limiting the measurement range from 20 Hz to 20 kHz (so called audio bandpass) the
value would be -113 dB again. This can be verified with RME's DIGICheck. The function Bit
Statistic & Noise measures the noise floor by Limited Bandwidth, ignoring DC and ultrasound.
The reason for this behaviour is the noise shaping technology of the analog to digital converters. They move all noise and distortion to the in-audible higher frequency range, above 24 kHz.
That’s how they achieve their outstanding performance and sonic clarity. Therefore the noise is
slightly increased in the ultrasound area. High-frequent noise has a high energy. Add the doubled (quadrupled) bandwidth, and a wideband measurement will show a significant drop in
SNR, while the human ear will notice absolutely no change in the audible noise floor.
39.7 SteadyClock
The SteadyClock technology of the Fireface UFX II guarantees an excellent performance in all
clock modes. Thanks to a highly efficient jitter suppression, the AD- and DA-conversion always
operates on highest sonic level, being completely independent from the quality of the incoming
clock signal.
SteadyClock has been originally developed to gain a stable and clean
clock from the heavily jittery MADI
data signal (the embedded MADI clock
suffers from about 80 ns jitter). Using
the Fireface's input signals AES and
ADAT, you'll most probably never experience such high jitter values. But
SteadyClock is not only ready for
them, it would handle them just on the
fly.
Common interface jitter values in real
world applications are below 10 ns, a
very good value is less than 2 ns.
The screenshot shows an extremely jittery SPDIF signal of about 50 ns jitter (top graph, yellow).
SteadyClock turns this signal into a clock with less than 2 ns jitter (lower graph, blue). The signal processed by SteadyClock is of course not only used internally, but also used to clock the
digital outputs. Therefore the refreshed and jitter-cleaned signal can be used as reference clock
without hesitation.
