3.
Channel 1 and 2 Inputs
These two combo jacks allow users to connect
either balanced XLR 3-pin connectors, for dynamic
or condenser microphones, or ¼” TRS phone jacks
for instruments such as electric or bass guitars.
NOTE: When plugging line-level signals into the
combo jacks, disengage the PAD button to lower
the signal level somewhat.
4.
Input Gain Controls 1 - 8
Turn these knobs clockwise to increase the
microphone/line input gain for the corresponding
channels. You have 50dB of gain to work with, but
be sure not to adjust it to a level that will make the
input meter hit the “clip” point. A good region to be
in is about -6dB – this will give you a greater signal
level with enough headroom to avoid clipping.
5.
PAD selector
This button controls the input sensitivity for channels
1 and 2. Pushing this button in will attenuate the
input signal by 20dB, allowing you to connect a
microphone or instrument to the combo input jack.

+48V Phantom Power
Pushing one of these buttons will activate the
+48V phantom power for the corresponding
channel, allowing you to use condenser or ribbon
microphones (or other devices that require +48V)
to work properly. Activation of phantom power will
be accompanied by an illuminated LED. If you are
not sure if your mic uses phantom power, please
refer to the microphone user’s manual.
9.
LED Level Meter
This stereo 6-segment LED meter displays the
signal level of sum of all 8 analog input channels.
User’s are advised to keep this meter sitting around
the -6dB mark to make the best use of audio possible
without causing any unnecessary clipping.
10. Channel LED Level Meters
The input/output signal levels from analog inputs/
outputs 1 to 8 are shown in these 4-segment LED
meters. Whether these meters display the input or
output level is dependant on the input/output select
button. Users are advised to try and keep their
signal level around the -20, -10 marks, as to avoid
distortion and clipping.
11. Input/Output Select Switch and Indicator
This button determines whether the LED level meter
will display the input or output signal of the Firefly
808’s input/output channels. This button is an easy
way to compare input/output levels. Depending
which setting is currently active, an LED will light
up next to the corresponding setting (“analog input”
or “analog output”).

This are balanced 1/4” TRS line outputs with line
level signal (+4dBu). Users are able to use these
outputs to get a stereo output channel from each
pair of odd and even numbered outputs, or even
a surround mix (5.2 or 6.2). Analog outputs 1 and
2 can be used to send a stereo mix of your analog
inputs or return signal, which is ideal for use with
subwoofers (if making a 5.2 or 6.2 system) or just
for monitoring the signal.
22. AES/EBU In/Out
This is a standard XLR AES/EBU digital interface
that lets you connect your digital AES-enabled
devices to your Firefly. The IN or OUT LED on the
front of the Firefly will light up when the inputs and
outputs are in use.

This switch determines which of these digital inputs
will be used.
24. S/PDIF In/Out
This is a standard RCA S/PDIF Digital Audio
Input/Output that can be used with digital mixers,
DAT recorders, or any external device that uses
the RCA Digital interface format. Please use a
75 ohms coaxial cable with RCA plug when using
S/PDIF. The most common problems or glitches
incorporated with S/PDIF transfer are due to use of
improper analog cables. Users may also use these
inputs for high-speed S/PDIF devices when that
option is selected in the computer's Firefly mixer
software.

FIREFLY 808
Installation
Insert the Cubase LE installation CD that came with
your mixer into the CD drive of your computer. Run
the installer. The serial number will be automatically
entered in when installing.
Setup
After successfully completing the installation process,
the following process must be followed to work efficiently with the Friefly.
1. Open the Cubase LE program.
2. Go to the ‘Devices’ pull-down menu and select ‘Device Setup’. On the left, select ‘VST Multitrack’.
3. From the ASIO Driver drop-down list select the
“Phonic ASIO Driver”. A pop-up box will ask you if
you want to switch the ASIO driver. Click ‘Switch’.
This completes the basic installation and setup.
4. Activating audio tracks received from the Firefly.
a. Go to the “devices” pull-down menu and select
‘VST Inputs’. This will display the various inputs (“Phonic FF808 Ch 1”, “Phonic FF808 Ch
2”, etc.)
b. Activate 8 of these channels by clicking the
“Active” button located next to each channel
name. Please note, only 8 input channels can
be activated at any one time. This is a limitation
of Cubase LE, and if more input channels are
needed, we suggest upgrading to a higher version of Cubase, or use other DAW software.
5. For further instructions on the operation of Cubase,
please consult the user manual by pressing F1
while the program is open.
If you wish to reset the Phonic ASIO driver, simply go
to the ‘devices’ pull-down menu and select ‘device
setup’. Simply click “reset” and select the “Phonic
ASIO Driver”. Click ‘ok’ to continue and the Firefly
808 should once again become functional.
13
FireWire Device Control Panel
The FireWire control panel can be accessed at any
time by entering choosing the shortcut from your Programs menu. This program will not only allow users
to alter their device and channel names and properties, but will also let them correct for latency issues,
change sampling rates, and so forth. When opening
the software, a number of options will be available for
users to select from, allowing them to adjust the available properties.
Output Channels
By entering the Output Channels section, users can
view and edit the names of the two output channels
from the computer to the Firefly 808.
Devices
In the Devices section, users are able to view and edit
the name of the Phonic FireWire Devices connected
to their computer.
Synchronization
In the Synchronization section, users can adjust the
sampling rate and other synchronization properties.
Many of these adjustable properties, as they are, are
set for optimum performance and, unless you are sure
of what you need to change, are probably best left
alone.
Input Channels
The Input Channels section allows users to view and
edit the name of the various input channels received
from the FireWire input. For a list of default channel
names, please consult the table on page 13.
First off, the synch mode can be altered, though making this alteration is not recommended for novice users. The synch mode is basically the way the computer determines what the ‘clock source’ (ie. device
that your computer will use to determine the timing of
all digital signals received) will be. The default setting for this feature is “CSP”, meaning the Firefly is
the “master” clock source of the device. The other
options allow users to make the FireWire follow the
“timing” of whichever device is the clock source. Having two clock sources has the potential to create very
undesireable audio, so it is best avoided. If the Firefly
is the only piece of digital audio equipment attached
to the computer, there is no reason this option should
be changed.
14
FIREFLY 808
Users are also able to change between automatic and
manual sampling rate settings. When the sampling
rate is manually set, users can select between sampling rates of 44.1, 48.0, 88.2, 96.0 and 128 kHz per
second for analog inputs and 176.4 and 192.0 kHz per
second for some digital devices. Many devices have
sampling rates that do not surpass 44.1 kHz per second, therefore, when using multiple digital devices,
users are advised not to exceed this level unless they
are sure the secondary device’s sampling rate can.
Settings
Users are able to adjust various buffer times in the
Settings section.
The Stream Buffer Depth is adjustable between 0.5
and 20 milliseconds. It adjusts the buffer used when
streaming a signal from the Firefly. If the depth is set
too high, an obvious latency will become evident. If the
depth is too low, various clicks and pops may become
obvious. It is best to set the Stream Buffer Depth to a
level that allows users to get the lowest latency, while
still maintaining an optimal performance. The default
settings are ideal for most computers.
FIREFLY 808
The ASIO Buffer Depth is adjustable between 4 and
40 milliseconds. This allows users to adjust the latency of the stream received by ASIO driver-based
software (including Steinberg Cubase LE).
The WDM (Windows Driver Model) Sound Buffer
Depth is adjustable between 4 and 40 milliseconds.
This allows users to adjust the latency of the stream
received by WDM based programs.
Also in this section, users are able to view their “drop
out statistics”, where the number of times the FireWire
connection has been interrupted can be viewed.
Streams
In the Streams section, the Firefly device properties
can be viewed. Each input and output stream can be
scrutinized, and the isochronous stream number and
its supported sampling rates can be viewed.

with the fader, mute and solo buttons being ‘linked’ to
two inputs.
4. Pan
Each of the Firefly’s inputs are set to either left or right
by default, with odd channels being set to the left, and
even channels being set to the right.
5. Fader
Click and hold the mouse button on the fader to adjust the volume of the signal coming into the computer
through the FireWire connection for each channel.
When in link mode, a single fader will control 2 channels simultaneously.

6. Level Meter
These two parts of the PC-based mixer give users an
idea of the input levels received through the FireWire
interface. The graphic bar will give visual representation of the level and users are able to read the exact
input level in decibels underneath the fader.
7. Channel Status (digital channels only)
This display window will show whether a digital device
is connected to or disconnected from the Firefly unit.
The status will be updated automatically when a digital device is connected to the correct inputs.

8. Balance
The balance control for the master output is set to the
center by default. Moving it to the left will attenuate the
right signal and intensify the left signal accordingly;
moving it to the right will do the opposite.
9. Fader
Click and hold the mouse button on the fader to adjust the volume of the stereo output signal being sent
through the FireWire connection to the Firefly. The
signal controlled by these controls is sent through the
Firefly’s analog outputs 1 and 2.
10. Level Meter
This gives users an idea of the output levels of both
channels sent through the FireWire interface. The
graphic bar will give visual representation of the level
and users are able to read the exact input level in
decibels underneath the fader.

Pushing this will allow you to use the Firefly 808 as the
sync source for all your digital gear.
12. Coaxial S/PDIF
Selecting this option will activate any coaxial S/PDIF
device as the sync source for your digital gear. If no
device is connected to the S/PDIF input on the Firefly
808, the corresponding sync source LED on the face
of the device will flash briefly then return back to the
previously selected sync source.
13. Optical S/PDIF
Selecting this option will activate any optical S/PDIF
device as the sync source for your digital gear. If no
optical S/PDIF device is connected to the TOSlink
ADAT input on the rear of the Firefly 808, the corresponding sync source LED on the face of the device
will flash briefly then return back to the previously selected sync source.
14. Word Clock
This option will allow you to
use a word clock as your sync
source. If no word clock device is connected to the BNC
word clock input on the rear
of the Firefly, then the corresponding sync source LED
on the face of the mixer will
flash briefly and then return
back to the previously selected sync source. Please see
the diagram below for information on hooking up a world
clock as your sync source.

19. SMUX
By selecting SMUX as your digital input/output device,
you are able to connect a SMUX enabled product to
the ADAT TOSlink inputs of the Firefly. The SMUX
output signal is typically 8 channel, however if you set
the sampling rate to 96 kHz, this is reduced to 4 channels.
Other Features
20. Sampling Rate Selection
Here you can select the sampling rate of the signal
sent to the computer. For most applications, you will
be able to select between 44.1, 48, 88.2 and 96 kHz.
If you choose ADAT as your digital input selection,
then you are able to select 44.1 kHz or 48 kHz. When
using high speed S/PDIF devices, you are able to select between 176.4 and 192 kHz sampling rates. If the
192 kHz sampling rate is set, the Firefly’s level meter
will be disabled.
21. Crossfader
The mixing software’s crossfader allows users to adjust the signal returned to the computer’s analog 1
and 2 outputs. When centered, the signal will be a 5050 mix of the pure signal received by the Firefly 808
and the signal returned to the 808 from the computer.
When pulled to the left, the monitor signal from the
808 gradually becomes more dominant; when pulled
all the way to the left, this signal is the only signal
audible. If this control is pulled to the right, however,
the stereo signal from the mixing panel software will
become more dominant.

Stand-Alone Mode
The Firefly 808 can work independantly, without any
FireWire connection being established. The following
is just a couple of points of interest that you may need
to know to use the Firefly in stand-alone mode.
Firstly, whatever settings you have made in regards
to inputs, outputs and sampling rates while using the
Firefly 808’s mixer software will be kept even after
you restart the device and/or disconnect the FireWire
cable. This means whatever inputs and outputs you
have set will be activated/deactived as per your previous settings. The default sampling rate is 44.1 kHz,
and the default digital input/output is S/PDIF.
Also, the analog inputs are routed to their corresponding analog outputs, as well as a mix of these inputs
being sent through any digital outputs that have been
set (ADAT, S/PDIF, etcetera).
