A few more questions that might help to herd the problem into a corner...
- Is the DSP plugged into the same circuit as the other equipment ? Just checking on this one...
I wanted to ask "how about switching off or unplugging the DSP and waiting for the P/S to bleed down" but a bit worried about spikes/noise going out to the amp & speakers so maybe skip that.
- Do you still get the hum if DSP is connected to amp inputs but preamp is not connected to DSP ?
- Is the hum on both L & R channels ? On both front and rear channels ?
