Thank you Fabio for writing this up - this was very helpful in sending me on the right path just today!
One thing I had to figure out in addition to your instructions which covered the input side of things, that I needed to do the same thing for the outputs, specifically:
Configure the OUT pairs to output the signal received from the respective ADAT inputs:
Click on OUT 1-2 on the right hand side
Set the faders for ADAT 1 and 2 to 0.00 (unity gain)
Pan ADAT 1 and 2 hard left and hard right
Mute the other ADAT channels
Proceed in the same fashion for all OUT pairs and correspondent ADAT inputs
and for the sake of completeness, here’s the added step for the inputs:
Configure the ADAT pairs to output the signal received from the respective MIC inputs:
Click on ADAT 1-2
Set the faders for MIC 1 and 2 to 0.00 (unity gain)
Pan MIC 1 and 2 hard left and hard right
Mute the other MIC channels
Proceed in the same fashion for all ADAT pairs and correspondent MIC inputs.
