Ghost in the machine?


This is weird. Speakers make noise, hum, buzz even when system is not turned on. It is plugged into power however. Happens randomly, sometimes nothing for days. Sometimes happens for an hour or so. Sometimes all day. WTF?

Have you tried to plug the amp to another circuit under another barker?
If nothing changes you may try a different amp.
You may also try to remove everything that's connected in the same circuit. If it happens randomly it may be a freezer or who knows what.
I would say your amp needs servicing. Something is wrong with the off circuit. Is it remote controlled?
Agree with Erik.
It`s probably amp.
But it doesn't hurt to check the circuit also.
