I installed a cooktop about 3 years ago and it became nightmare of noise in my REL subs. At first, I had no idea what was making my subs hum. It wasn't a ground loop. I sent them to Pyramid Audio and they found no problem. I have 4 dedicated lines & a Furman Ref IT15 and they did nothing to silent the humming. After much research, I determined it was a DC issue caused by the cooktop. I purchased 2 Emotiva DC blockers & no noise
Can moving wire location at circuit breaker reduce hum?
The power line going into my music room will oftentimes make the amps’ transformers hum. I’ve tried many things but have had no luck. If I take any component that’s humming into a different room run on a different circuit breaker, the hum disappears.
Would swapping out the wires that go into the two separate rooms at the breaker make any difference? Or is it more likely that one of the outlets on the circuit that goes into my music room is somehow miswired and is causing the hum? I can unplug everything from the circuit except for my amp and it still hums.
Any suggestions on what I might be able to do short of hiring someone to run a dedicated line?
Thanks,
Mamoru
