1. Introduction
XLogic Delta-Link MADI HD
Congratulations on your purchase of the XLogic Delta-Link MADI HD! Please be assured that it will provide you with many
years of reliable service while delivering the pristine audio quality you expect from any Solid State Logic product.
The Delta-Link MADI HD is an elegantly styled, 1U high, rack mountable unit. The front panel design is reminiscent of the
rest of the XLogic Alpha-Link range… rather understated in this case: since the unit is controlled from the computer, the only
front panel controls are the power switch, the power LED and a lock indicator LED.
Using Delta-Link MADI HD you can hook-up a standalone, MADI compatible multi channel I/O and format conversion unit
to a Pro Tools® HD core or Pro Tools® HD Accel card(s). Solid State Logic has a number of such I/O units:
• XLogic Alpha-Link MADI-SX (64 MADI I/O, 12 stereo/24 mono AES/EBU I/O, 24 balanced analogue I/O).
• XLogic Alpha-Link MADI-AX (64 MADI I/O, 24 ADAT I/O, 24 balanced analogue I/O).
The Delta-Link MADI HD is also suitable for applications where Pro Tools® audio hardware is used with third party software
packages (e.g. Logic Pro 7).
IMPORTANT: Please register your XLogic Delta-Link MADI HD on our website. This will ensure that you receive
notification of future updates and other important information, and that your guarantee is registered. Registration will
also make you eligible for technical support.
The Solid State Logic home page is at: http://www.solidstatelogic.com

3. Installation
The Delta-Link MADI HD package includes:
• The Delta-Link MADI HD unit.
• 2 of 0.9m (35") DigiLink cables.
• The mains connection cable.
• This manual.
NOTE: The maximum allowable length of cables required to connect the Digidesign® cards to the Delta-Link MADI HD
(DigiLink cables) varies as follows according to the sample rate being used:
• 48kHz operation: 1.8m (70")
• 96kHz operation: 0.9m (35")
• 192kHz operation: 0.45m (18")
If required, Delta-Link MADI HD can be rackmounted. It occupies 1U of rack space in a standard 19-inch rack.
It is assumed that your Pro Tools® HD system is already installed in the host computer (Windows PC or Mac OS X).
8
1. Connect Primary Port A of the Delta-Link MADI HD to Primary Port A of your Pro Tools® HD system and Primary Port
B of the Delta-Link MADI HD to Primary Port B of your Pro Tools® HD system via DigiLink cables supplied. The Pro
Tools® software can be used to control internal settings of the Delta-Link Madi HD. This functionality uses Primary Port
A only, so it is important that this connection scheme is followed.
WARNING!
Do not connect or disconnect the Delta-Link MADI HD to/from the Pro Tools® cards or power cycle the unit
while the Pro Tools® software is running. Doing so will loose all interface settings, recovery from which will
require each option to be toggled on the Pro Tools® I/O set up page – refer to Section 6.
2. Connect a suitable Word or Frame clock source to the WordClock input at the rear of the Delta-Link MADI HD.
(see overleaf)
3. Connect the mains cable to the mains connector of the Delta-Link MADI HD.
4. External devices may now be connected to the MADI inputs and outputs.
5. Power up the computer that hosts your Pro Tools® system, and power up the Delta-Link MADI HD (using the power
switch on the front panel).

4. Synchronization
Pro Tools® HD card
The Pro Tools® HD card is designed to operate as a Clock Slave, locking to a clock reference signal provided by the audio unit
connected to its primary port.
Delta-Link MADI HD
The Delta-Link MADI HD, like the Pro Tools® HD card, is designed to operate as a Clock Slave. Once the card and
Delta-Link MADI HD are connected together, they can be seen as a unit requiring an external clock reference signal. However,
this unit now has MADI ports, instead of the “Digital and Analogue” connections to other devices provided by Pro Tools®
interfaces.
Although a reference signal is embedded in the Primary port, the MADI connection requires a separate WordClock signal.
Therefore, the Delta-Link MADI HD is equipped with a WordClock input connector.
Depending on the type of unit that is connected to the MADI port, the sample rate will no longer change automatically when
a setting is selected in the PC or Mac software (because there is no command channel). Therefore, the sample rate must be set
manually at both ends (in the Pro Tools® software and on the hardware connected to the MADI port).
10
WordClock / FrameClock
The WordClock input can translate WordClock or FrameClock to the required Sample Rate. The “LOCK” LED on the front
panel indicates reception of a stable signal.
NOTE: When a “multiplexing” mode is used for digital audio transfers, the frame rate of the audio clock is equal to the
audio sample rate at up to 48kHz, half of the audio sample rate at up to 96kHz or a quarter of the audio sample rate at up
to 192kHz. The term “FrameClock” denotes an audio clock signal that is proportional but not always equal to the sample
rate, therefore:
• At 44.1kHz, 88.2kHz or 176.4kHz, the frame rate is 44.1kHz.
• At 48kHz, 96kHz or 192kHz, the frame rate is 48kHz.
NOTE: To understand this topic fully, it is important to read the AES MADI specification – AES 10 –2003 (www.aes.org).
11
5. Sample Rates and I/O Mapping
High Speed and SMUX modes
• Sampling frequencies up to 48kHz are designated as being in the “NFS range” (from NFs, Normal Frequency sampling).
• Sampling frequencies above 48kHz and up to 96kHz are in the “DFS range” (from DFs, Double Frequency sampling).
• Sampling frequencies above 96kHz and up to 192kHz are in the “QFS range” (from QFs, Quadruple Frequency
sampling).
At high sample rates (in the DFS and QFS ranges), the MADI interface can operate in either of two modes; High Speed or SMUX:
DFS range (88.2kHz to 96kHz)
The MADI interface can operate in High Speed or SMUX2 modes. In High Speed mode the MADI-embedded reference signal
has a frequency of 88.2kHz to 96kHz. In SMUX2 mode, the frequency is 44.1kHz to 48kHz.
QFS range (176.4kHz to 192kHz)
The MADI interface can operate in High Speed or SMUX4 modes. In High Speed mode, the MADI-embedded reference
signal has a frequency of 176.4kHz to 192kHz. In SMUX4 mode, the frequency is 44.1kHz to 48kHz.
NOTE: To understand this topic fully, it is important to read the AES MADI specification – AES 10 –2003 (www.aes.org).

6. Pro Tools Software
®
General information
The Delta-Link MADI HD can work with Pro Tools® HD systems running on a Windows PC or Macintosh OS X computer.
Using the Delta-Link MADI HD with the Pro Tools® software is generally straightforward. However, there are a few points
to be aware of:
• The Delta-Link MADI HD appears in the Pro Tools® software as four Digidesign® 192 I/O units, except when operating
at 176.4 or 192kHz, in which case it appears as two Digidesign® 192 I/O units.
• The MADI inputs and outputs appear in the Pro Tools® software as Analogue or Digital (AES/EBU or ADAT) inputs and
outputs belonging to these four Digidesign® 192 I/O units. Therefore, you will not find any MADI inputs or outputs listed
in the Hardware Setup page of the Pro Tools® software (select Setup|Hardware). Please use the inputs and outputs that
are listed, regardless of their denomination – they are really your MADI inputs and outputs – and do not select “None”.
17
The screenshot below was made using a Pro Tools® HD system with a single Delta-Link MADI HD which appears as a set of
192 I/O peripherals (see below, top left). All the inputs and outputs listed belong to this single unit.
18
Remote control of Delta-Link MADI HD settings
Some Delta-Link MADI HD system settings can be controlled via the Analog Out tab of the Pro Tools® software’s Hardware
Setup window (select Setup|Hardware).
19
In the Hardware Setup window, the “Output Trim” settings are irrelevant to the Delta-Link MADI HD because its inputs and
outputs are all digital. Therefore, they can be used to set various Alpha-Link parameters as follows:

Narrow deviation is typically used for Audio editing. The Lock LED on the front panel will light when the received
Wordclock is within ±0.5%. This mode is valid for both 56/28/14 and 64/32/16 channel modes.
Wide deviation is typically used for Video editing. In this mode, varispeed is allowed up to ±4.2% (all Sample Rates).
This mode is only valid for 56/28/14 channel mode.
Note: Selecting both wide deviation mode (±4.2%) and 64/32/16 channel mode is invalid and will result in poor audio
performance.
20
Known issues
Start up errors
When the Pro Tools® software starts up, it uses the settings defined during the previous session, e.g. number and type of Audio
Interfaces, I/O setup, etc.
If you have used a Legacy Audio Interface (defined through menu: Setup|Hardware), and then replaced its current Audio
Interfaces with the Delta-Link MADI HD, the Pro Tools® software will display the following error message: “DAE error -1125
was encountered”. This is because the Legacy Audio Interface cannot be detected anymore. After clicking “OK”, the Pro Tools®
software will close without allowing you to change the Hardware setup!
Solution 1. (Mac or PC)
• An easy way to get around this problem is to startup Pro Tools® with the Delta-Link MADI HD switched OFF. The
following message will eventually be displayed: “Unable to find an Audio Interface attached to..”. At this point, power
up the Delta-Link MADI HD and click “OK”. Pro Tools® will then continue its start up procedure.
Solution 2. (Mac Only)
• Another way to solve this problem is to delete the “DigiSetup.OSX” file and the “DAE prefs” folder in the
“Library/Preferences” folder. This will force Pro Tools® to start up using a default configuration (48kHz, limited
“Voices”, no Hardware knowledge...)
For either solution, now go to menu: Setup|Hardware and make sure all Legacy Interfaces are removed from the Peripherals
list (see over leaf).
21
The best way to ensure all Legacy Interfaces are removed is to click the name of a Legacy Audio Interface (e.g. 882/20 or
888/24) and to select “No Interfaces” from the “Interface” drop down box. After the Legacy Interfaces have been removed,
select the 192 I/O device, click the “Main” tab and select “Expansion I/O” in the “Port Settings” section. As a result, you will
see the second 192 I/O device appearing in the “Peripherals” list.
22
Playback Engine
The Delta-Link MADI HD provides up
to 64 input and output channels.
Therefore, the number of voices for the
Playback Engine may need to be
increased.
For instance, in order to playback and
record 64 tracks simultaneously at
96kHz, go to menu: Setup|Playback
Engine and select “128 voices”.
23
7. Troubleshooting
System Resources
The system resource usage can always be checked in the
Pro Tools® software under menu: Window|System Usage:
Firmware Updates
The Delta-link MADI HD features a USB connector on the
back panel to allow for firmware updates.
When a new firmware update is released, an update utility will
be available from the downloads section of the Solid State
Logic Support Website.
NOTE: The interface is USB 1.0 compatible only.
NOTE: Please do not switch the unit off, disconnect the
USB cable or switch off the controlling computer whilst
upgrading the firmwire. Doing so may leave the Delta-Link
MADI HD in an unusable state.
Technical support
If you encounter problems that you cannot solve, please check
out our online knowledge base at http://solid-state-logicen.custhelp.com for trouble shooting tips or to get assistance
from our technical support team.
24
Symptoms
The Delta-Link MADI HD
is not detected by the software.
There is no sound or there is
noise. The Lock LED flashes.
The Delta-Link MADI HD
is recognized by the Pro Tools
software and the Lock LED is lit.
However, there is no sound.
Bad audio.
Possible solutions
Check that the Delta-Link MADI HD is connected to the mains supply and that the
Power switch is in the On position (the Power LED should be lit). Check the
condition of the mains cable. Check that the Delta-Link MADI HD is connected to
the Pro Tools® HD cards via suitable DigiLink cables and check the condition of
these cables.
Check that the Delta-Link MADI HD is receiving a suitable WordClock or
FrameClock signal compatible with the Sample Rate selected in Pro Tools®.
Check the MADI connections and the condition of the MADI cables. In particular,
make sure that the MADI inputs of the Delta-Link MADI HD are connected to
MADI outputs and vice versa of the other device(s). Please note that MADI cables
are sometimes marked “A” at one end and “B” at the other end, which can be
confusing and sometimes results in two MADI inputs or two MADI outputs being
interconnected by mistake.
This may be caused by a MADI mode mismatch between the Delta-Link MADI HD
and the device connected to its MADI ports (e.g. a unit from the SSL Alpha-Link
MADI series). The MADI format allows either 56/28/14 or 64/32/16 input/output
channels, depending on the selected Sample Rate. Devices connected via MADI
must use the same MADI mode! (For an SSL Alpha-Link MADI interface, please
refer to the corresponding manual.)
