No issues with the balanced outputs here. (connected to a KRK S10.4)
I did notice that connecting optical 1 and coax 1 simultaneously doesn't work for some reason. I mean, selecting coax 1 doesn't work properly when there's a signal going to optical 1 too. I had my PC running (optical 1) and had my DVD player connected to coax 1. I wanted to play a CD in the DVD player but that didn't work. When I connect the DVD player to coax 2 it works fine.
When the PC is in sleepmode (still connected to optical 1), I can connect the DVD player to coax 1, I can play a CD but it still stutters.
Is this normal behavior?
Meaning, you cannot have 2 optical inputs AND 2 coal inputs connected? It's OR you connect 1 optical and 1 coax OR 2 optical OR 2 coax?
