Programming digital inputs 1 and 2 as S/PDIF.
In order to use S/PDIF inputs, the programming described below adapts levels and
unbalance signals by joining IN1- and IN2- to their associated grounds, so each signal
is taken from the corresponding IN+ and its GND (or IN-). Take note that when the rear
switch is in USB position, the digital input 2 will be placed at the USB connector
regardless of the configuration programmed by jumpers.
At the "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 (up) to position 2-3 (down), as shown in the following
image:

Programming digital outputs 1 and 2 as S/PDIF.
In order to provide outputs to S/PDIF equipments, the programming procedure
described above adapts the levels and unbalances the signals by joining OUT1- and
OUT2- to their corresponding GND, so the signal is taken from each OUT+ to OUT– (or
GND). Take note that the digital output 2 will be duplicated at the USB connector
regardless of the configuration programmed by jumpers.
At the "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 (up) to position 2-3 (down), as shown in the previous
image.
