8.2 Internal Connections

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
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.
ADAT 1 OUT
This internal ADAT output carries the same audio data as the optical output 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.
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.
WORD CLOCK MODULE
10-pin connector for 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.
Blue Jumper
This is no internal input or output. The blue jumper allows to change the 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 effective
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.
