Not sure what's going on, but my Focusrite Octopre is connected to a FW host (RME Fireface 800) via ADAT optical and I'm getting an ungodly hum on the first two channels, which can be connected to via 1/4" in the front or XLR in the rear. The hum has come whether I'm plugged into the front or rear.
I know the unit is the source because the RME can operate without it. Also, I've gotten the noise when my mixer is bypassed. I've tried different cables too...
Sometimes when I turn the unit off and back on, the noise disappears...
I'm not a real gear-head, but I'm wondering if this might be a shielding problem. But could it be digital? Right now, the RME is the Master clock, via BNC cable, despite the fact that Focusrite recommends the Octopre be master since it is sending ADAT clock. I have not done this yet.
