Hi guys,
I'm new here, and I have an issue that I just can't seem to solve.
I have a dm-4800 in my studio and have it rigged to have the send and returns run through my patchbays in to the live room for a headphone amp (sends), and 8 1/4 ins to the returns.
Here's my issue. No matter what I do, I get hum on the sends and returns.
Things I've tried:
1. Eliminate the patchbays from the chain and run directly through to the live room from the desk.
2. Use both balanced and unbalanced cables.
3. Run direct in to the headphone amp with a sound source and it is fine.
4. Run in to the returns directly (not through the wall), and still hums.
5. Reconfigured/double checked my routing in the mixer and Sonar.
6. Unplugged anything else that was plugged in to the power chain.
7. Run everything from a different power circuit in the house.
I'm not sure what else to try. Maybe I'm just missing something totally stupid?
Anyway, I'm really frustrated and could use a hand.
Thanks in advance.
-John
