Connections on the Rear Panel
1) OUT 1-8 - This DB-25 connection provides analog
outputs 1-8; analog outputs are balanced line level sig-
nals at a nominal level adjustable between. Apogee’s
DA8-IFC breakout cable can connect here to provide 8
XLR male connecters. (pinout Figure 3).
2) OUT 9-16 - This DB-25 connection provides analog
outputs 9-16. Apogee’s DA8-IFC breakout cable can
connect here to provide 8 XLR male connecters (pin-
out Figure 3) .
3) OPTION - This slot is reserved for Apogee’s X-Series
Option cards, which provide additional digital input
formats, such as FireWire or Digidesign HD.
4) ADAT – S/MUX These Toslink connections accept
ADAT or S/MUX format optical inputs according to the
front panel configuration. Figure 4 indicates the Tosllink
connectors used for each Optical format accepted. To
use Optical input as a clock or input source, the ADAT
1-8 input must be connected first in precedence.Only
8 channels may be input when using the S/MUX 4
format.
5) AES IN – This DB-25 connector accepts 16 chan-
nels of AES-EBU Single wire input and 8 channels of
Double wire input (pinout Figure 5). Apogee’s AES16-
IP-IFC breakout cable can connect here to provide 8
XLR female connectors.
6) WC IN - This BNC connection accepts a TTL Logic
clock signal. Termination of the word clock input may
be engaged with an internal switch; please see “Inter-
nal Adjustments”.
7) WC OUT - This BNC connection provides a TTL Logic
clock signal output.
8) WC IN Termination Switch - When this switch is
pressed IN, a 75 ohm load is engaged across the word
clock input; when the switch is OUT, the word clock
input is unterminated (Figure 6).
9) AC - This IES connection accepts an AC input of 100
to 240 VAC at a frequency of 50 to 60 Hz.
