Could be an induced hum from power and i/cs or speaker cables running parallel and in close contact, or could be ground loop. Try cheater plug at in-wall outlet; if noise goes away it was a ground loop. If not, then its the cabling layout which you will have to rearrange to eliminate parallel runs of ac and ic/speaker wires. If they must cross, try to do it at right angles.
Hum Noise from Plug or Wire Area ? ?
Recently my speakers are giving this hum noise if amp and preamp are plug in where the interconnects and wires run behind my system. If I plug the amp or preamp in a different outlet the noise if gone of at least down to a "wisper". I know its not the speakers, I just can not figure what to do. I have everything plugged into a "Inland" power bar, if I plug directly to the wall plug in that area i get the hum noise.
Any suggestions as to whats going on ? ?
Thanks
