Programming digital outputs 1 to 4 as S/PDIF.
In order to provide outputs to S/PDIF equipments, the programming procedure
described below adapts the levels and unbalances the signals by joining OUT1-, OUT2-
, OUT3- and OUT4- to their corresponding GND, so the signal is taken from each OUT+
to OUT- (or GND).
At the "1 TO 4 DIGITAL INPUTS AND OUTPUTS PROGRAMMING ZONE", you can
change the outputs one by one from AES/EBU to S/PDIF by moving the 4 jumpers
associated to each output from position 1-2 (down) to position 2-3 (up), as shown in the
following image:
Position 1-2: AES/EBU
Position 2-3: SPDIF

Programming digital inputs 1 to 4 as S/PDIF.
In order to use S/PDIF inputs, the programming described above adapts levels and
unbalance signals by joining IN1-, IN2-, IN3- and IN4- to their associated grounds, so
each signal is taken from the corresponding IN+ and its GND (or IN-).
At the "1 TO 4 DIGITAL INPUTS AND OUTPUTS PROGRAMMING ZONE", you can
change the inputs one by one from AES/EBU to S/PDIF by moving the 5 jumpers
associated to each input from position 1-2 (down) to position 2-3 (up), as shown in the
previous image.
