Subwoofer hum and Directv (1 Viewer)

[Mike Shin]

My subwoofer makes a low but annoying hum. I can stop the problem by disconnecting the cable to the satellite box, but then I can't watch movies.

I read about using a cheater plug but some people posted that it is dangerous.

I tried connecting a 75-300 ohm convertor with a 300-75 ohm convertor as suggested by some posts, but then my satellite receiver can longer get a signal.

Does anyone else have this problem?

Thanks,
Mike

Radio Shack sells a Ground Loop Eliminator for $15 that should fix your problem. Floating your ground with a two prong adapter is not as dangerous as some would have you believe. That would only set you back about a dollar. Just don't adjust your stereo while standing in a bucket of water. There are many pieces of audio equipment that come with two prong powercords.

I actually found an old cheater plug laying around the house. Works great, no more hum. The instruction manual for my Hsu vtf-2 actually recommends this.
