6.2 Internal Connectors

SPDIF / ADAT IN

This internal digital input can be used with both SPDIF and ADAT.

SPDIF

• Connection to an internal CD-ROM drive with digital audio output. Allows for a direct trans-

fer of digital audio data within the computer.

• Connection to a SPDIF output of another card. This internal SPDIF connection can be

used to synchronize multiple cards with sample accuracy, and without the need for an ex-

ternal connection. Please note that the coaxial SPDIF input can no longer be used.

ADAT

• Connection to a TEB (TDIF Expansion Board). The highest sample rate is 96 kHz, the 4-

channel Double Wire mode (S/MUX) is automatically activated in Double Speed mode. Se-

lect AEB /TEB ADAT In in the Settings dialog.

• Connection to an AEB4-I or AEB8-I. When using these (no longer available) Expansion

Boards ST7 must also be connected to the Expansion Boards. The highest sample rate is

48 kHz. Select AEB / TEB ADAT In in the Settings dialog. In this mode, the optical input

can only be used as optical SPDIF input.

ADAT OUT

This internal ADAT output carries the same audio data as the optical output ADAT in ADAT

mode. Connecting an AEB4-O or AEB8-O, the highest sample rate is 48 kHz. Connecting a

TEB the highest sample rate is 96 kHz, the 4-channel Double Wire mode (S/MUX) is automati-

cally activated. The internal ADAT output stays active, even when the optical output is switched

into SPDIF operation. Please note the label GND for correct polarity.

AI4S-192 / AO4S-192

26-pin connector for the optional analog expansion boards, AI4S-192 and AO4S-192. These

expansion boards are detected automatically and self-registered by the driver. The additional

channels are displayed automatically in TotalMix as well.

SYNC IN

Internal word clock input for synchronization of multiple cards via SYNC OUT.

SYNC OUT

This 3-pin connector carries an internal word clock signal. It can be used to synchronize multi-

ple cards with sample accuracy, and without the need for an external connection. The card

where SYNC OUT is used is Master, the one with SYNC IN is Slave. In the Settings dialog the

Slave has to be set to Sync In under Pref. Sync Ref, the Clock Mode must be set to AutoSync.

WCM / TCO (X403)

10-pin connector to connect the optional 9632 Word Clock Module or the optional Time Code

Option (TCO) via flat ribbon cable.
