Radio Interference in Panasonic Subwoofer

post #1 of 4
Thread Starter 
Hello,
I have a Panasonic home stereo system. I'm at work and don't have the model number. But, it's a 5 disc DVD player with am/fm stereo built in. The dvd/receiver unit plugs into the sub which plugs into the ac wall outlet. The speakers also plug into the sub.

I live in LA, near downtown LA, and I am picking up Mexican radio stations through the sub.
I have unplugged the speakers from the sub and the interference continues.
With the receiver switched to Aux or DVD or anything other than a radio (ie no sound coming through the speakers) the interference persists. Turning the volume up or down does not alter the interference. It is at a constant volume level.
The cable that connects the receiver to the sub is weird shaped. Sort of in the shape of a computer printer cable.

Any suggestions? It's really frustrating since I can't watch anything when the interference is really loud and interrupting dialog on shows. I live across the street from a concert venue and the other day they had the same problem with one of their amplifiers. I think someone in the sound booth did something (flipped a switch or something) because the interference stopped immediately after the band brought it to his attention. (They weren't playing and we all heard the interference stop, it wasn't that the band played loudly and we simply couldn't hear it.) I mention this in hopes that maybe there is some sort of "box" or something I can get that will boost a signal or something along those lines since this seems to be a problem in the area.

Thank you!

If you are very close to a broadcast tower you could be picking up RF interference directly. A quick check is to build a crude Faraday cage by wrapping the subwoofer (which is providing the power) in aluminum foil. Alternatively, the cable from the 'receiver' to the 'subwoofer' may not be sufficiently shielded to block RF interference or the 'receiver' may be picking up the RF interference directly.

wwinkler,
Thanks for the reply. So, just wrap the sub in aluminum foil and that might resolve the interference? Or, wrap the cable in aluminum foil to resolve the interference?

With the cable, you want to replace it (if possible) with a quad shielded connector that in ordinary situations you can get at Home Depot, Radio Shack, monoprice.com, Parts Express, etc. You may have a proprietary connector that is not easy to replace, etc.
