8.2 Internal Connections

AEB1 IN / CD 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

transfer of digital audio data within the computer.

• Connection to SYNC OUT of another card. This internal SPDIF connection can be used to

synchronize multiple cards with sample accuracy, and without the need for an external

connection. The card of which SYNC OUT is used will be master, the SYNC IN one will be

slave. SPDIF In / Internal has to be selected in the Settings dialog. Additionally Pref. Sync

Ref has to be set to SPDIF In for this internal connection to work properly. Please note that

the external SPDIF- or AES input can no longer be used then.

ADAT:

• Connection to an AEB4-I or AEB8-I. When using these Expansion Boards ST7 must also

be connected to the Expansion Board. The highest sample rate is 48 kHz. Select AEB /

ADAT Int. in the Settings dialog. In this mode, the optical input can still be used as optical

SPDIF input.

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

channel Dual Line Mode (equals SMUX) is automatically activated in double speed mode.

Select AEB / ADAT Int. in the Settings dialog.

AEB2 IN

Jumper ST5 allows to connect a second AEBx-I. Remove the jumper (factory default position

ADAT2 IN), and connect the 2-core cable of the AEBx-I to position ’AEB2 IN’. Please note the

label GND for correct polarity. The optical input ADAT2 can’t be used in this configuration.

ADAT 1 OUT

This internal ADAT output carries the same audio data as the optical output ADAT1 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 Dual Line Mode (equals SMUX) is

automatically activated in double speed mode. The internal ADAT output stays active, even

when the optical output is switched into SPDIF operation. Please note the label GND for correct

polarity.

ADAT 2 OUT

This internal ADAT output carries the same audio data as the optical output ADAT2. See ADAT

1 OUT for details. Both ports can be used to operate one AEBx-O each, for a maximum of 16

analog outputs.

SYNC OUT

This internal SPDIF output carries the same audio data as the external phono or XLR output. It

can be used to synchronize multiple cards, see above. Please note the label GND for correct

polarity.

14-pin connector for the Expansion Board connection via flat ribbon cable.

The connectors SYNC1, SYNC2 and ST9 have no function at this time. They are reserved for

future enhancements.

X4 is a connector to program the card in the factory.
