6.2 Internal Connectors

CD / AEB / SYNC 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 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.

ADAT

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

be connected to the Expansion Boards. 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 Double Wire mode (S/MUX) is automatically activated in Double Speed mode. Se-

lect AEB / ADAT Int. in the Settings dialog.

ADAT 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 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.

SYNC OUT

This internal SPDIF output carries the same audio data as the external phono output. It can be

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

WORD CLOCK MODULE

10-pin connector for a connection of the optional HDSP 9632 Word Clock Module via flat ribbon

cable.

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.

Blue Jumper

This is no internal input or output. The blue jumper allows to change the card's power-on delay

when booting the computer. Factory default is jumper in place. The FPGA of the HDSP 9632

will then be booted about 0.5 seconds after switching on the computer. This provides an effec-

tive way to get rid of problems caused by unstable power supplies in the moment of power-on.

In case this delay will become a problem some day (very unlikely, and no system known so far),

the jumper can be pulled. The delay is then reduced to 30 ms.
