buzz in home speakers

[JcMack]

Another thing that could give you a problem is near proximity of any cordless phones. If I use my cell phone near my computer speakers I get noise created by the RF from it. Any other devices such as wireless computer hook ups (Linksys) etc could also create a problem.

yes that's a good one!

1. Swap polarity of one of your sets of speaker wires at the speaker. If that fixes that speaker, do likewise to the other. This is why a lot of speaker wire indicates polarity of the pairs in some way. That's a basic stereo hum fix.

2. I had a hum problem with my bedroom set up (PC and DVD player/recorder hooked up to an Onkyo receiver). It turned out to be the crappy wiring (everything is crappy here) in the apartment. I looked up [I believe] "cycle hum" on the net and found a couple of solutions. One was a purpose built filter between the cable TV and the DVD player/recorder and the other putting a 75ohm and a 300 ohm filter back to back between them with a 75 to 300 home adapter connecting the 300 ohm filter to the player/recorder. Got rid of the hum immediately.
