ATI 1505 Hum? (1 Viewer)

[Christopher_Ham]

I have an ATI 1505 and there is a hum in the front two channels only, not in any of the others. I switched speakers around to see if that was the problem but only the front two channels hum, not matter what speakers are hooked to them. I am running a DC-1 with it. I can turn off the amp (It takes about 30 seconds for it to power down and the hum is still there. It is plugged into a monster power conditioner, what else should I try?

What was it? A ground loop? Interference from nearby electronics?

 

[ChrisHeflen]

You're welcome.
Let me know if it was helpful.

It must have been a ground loop problem, because I got an adapter, removed the ground prong, plugged the amp into it and then into the socket and it was gone!!

Thanks

Could you be more specific about the solution to your hum problem? I also have the ATI 1505 and experience some ground loop hum that I have not been able to isolate. It sounds like you used a cheater plug. Is that correct?
