How come I get a humming noise from my speakers?

by on December 17, 2009

Q: I have an old (10yrs+) stereo receiver and I have connected some old (10yrs+) bose speakers and sub woofer to it. I have my cable box and PC connected as well but I was getting a Humming from the speakers. I bought a Ground loop isolator from Radio Shack and now I am getting two radio stations mixed into my audio and still a slight huumming! What can I do?

    The problem could be just about any component you have plugged in, or wires, though I’d focus on the receiver first. I’d suggest trying a different receiver, borrow one from a friend or neighbor if possible that is known to be working fine and see if that fixes the issue. From there try different speakers, different wires, etc. Through the process of swapping in parts that are known to work you should be able to identify the culprit. Good luck!
