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.

Each Pro Tools HD port provides 32 input and output channels, regardless of sample rate.  
MADI A / MADI B  
The two MADI ports provide up to 64 input and output channels, depending on sample rate. Both MADI interfaces are fibre  
optic using SC-type connectors; we offer a separate external MADI coaxial to optical converter solution to interface Delta-Link  
MADI HD into coaxial systems.  
USB  
The USB interface can be used to control various settings of the Delta-Link MADI HD hardware and to update the internal  
firmware. This interface is USB 1.0 compliant and uses a Style-A USB connector.  
WordClock In  
This input must be used to supply a clock reference signal to the Delta-Link MADI HD.  
Power  
The unit is powered by an internal, auto-switching power supply. The connector is an IEC 320 type.

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:  
• 48 kHz operation: 1.8m (70")  
• 96 kHz operation: 0.9m (35")  
• 192 kHz 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. In a typical setup, connect Primary Port A of the Delta-Link MADI HD to the Primary Port of your HD Core card and  
Primary Port B of the Delta-Link MADI HD to the Primary Port of your first HDAccel card via DigiLink cables supplied.  
®
Technically, any Primary Port of the Delta-Link MADI HD is compatible with any Primary Port of a Pro Tools HD  
system, however, connecting Primary Ports A and B of the Delta-Link MADI HD to consecutively numbered Primary  
®
Ports of the Pro Tools HD system is preferable in order to maintain clarity when working in the I/O Setup page of the  
®
Pro Tools software.  
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. The interface unit can define the sample rate internally, or can itself be synchronized to an  
external reference signal (e.g. WordClock).  
Whenever the user selects a sample rate setting in the PC or Mac software, the corresponding command is sent to the interface  
unit.  
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:  
Channel Number  
Parameter  
If “A” is selected  
If “B” is selected

The 56/28/14 channel MADI mode of the Delta-Link MADI HD does not currently support varispeed operation whilst the  
64/32/16 channel MADI mode for any unit can only run at fixed rate. In both modes the Delta-Link MADI HD unit’s tolerance  
for sample rate variation is 0.5%.  
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 ProTools  
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 ProTools 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  
Firmware Updates  
The system resource usage can always be checked in the The Delta-link MADI HD features a USB connector on the  
®
back panel to allow for firewire updates or settings  
modifications.  
Pro Tools software under menu: Window|System Usage:  
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.

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! Varispeed operation is not currently supported  
– changing the seeings of the other device is necessary. (For an SSL Alpha-Link  
MADI interface, please refer to the corresponding manual.)

used in accordance with the instructions, may cause harmful interference to radio  
communications. However, there is no guarantee that interference will not occur in a  
particular installation. If this equipment does cause harmful interference to radio or  
television reception, which can be determined by turning the equipment off and on, the  
user is encouraged to try to correct the interference by one or more of the following  
measures:  
Reorient or relocate the receiving antenna.  
Increase the separation between the equipment and receiver.  
Out of Warranty Repairs  
Connect the equipment into an outlet on a circuit different from that to which  
the receiver is connected.  
In the event of a fault arising after the warranty period has expired the unit should be  
returned to Solid State Logic either directly or via your local dealer. You will be charged  
for the time spent on the repair (at Solid State Logic's current repair rate) plus the cost  
of parts and shipping. Note that no units can be accepted for repair without prior  
arrangement (see below).  
Consult the dealer or an experienced radio/ TV technician for help.
