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.
Reading conventions Software menus Where appropriate, to indicate a “path” under a Solid State Logic or Pro Tools® software menu, the following format will be used; menu: Header|Submenu 1|Submenu 2|Submenu 3|Item. Screenshots The appearance of SSL or Pro Tools® software on your computer screen may be different from the screenshots in this manual. This could be because you are using a different operating system or operating system version or because you are using different display settings, etc.
2. Overview Front panel Power switch Power switch This switch is used to power the unit up or down. Lock LED Power LED Power LED This LED is lit when the Delta-Link MADI HD is switched on. Lock LED This LED indicates that a WordClock signal is received: • It is lit when the Delta-Link MADI HD is receiving a stable signal at the required sample rate. • It flashes slowly when the Delta-Link MADI HD is receiving a stable signal at an incorrect sample rate. (See Section 5.

Primary Port A / Primary Port B 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.
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.
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 HD Accel card via DigiLink cables supplied.
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.
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.
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).
I/O mapping and Sample Rate range NFS range (44.1kHz to 48kHz): 64-48 “normal” mode NFS range (44.1/48kHz) Normal Mode Two Primary Ports interact with one MADI Port.

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 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.
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).
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 MADI NFS mode Normal Special 1 Number of MADI channels 3 MADI DFS/QFS mode 2 4 WordClock input 56/28/14 SMUX WordClock 64/32/16 High Speed FrameClock (48kHz /44.
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”.
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.
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”.
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 firewire updates or settings modifications. 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.
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.
