I am using the Mondial "magic" box and am very pleased with it. I had a similar "hum" caused by a cable tv hookup and the box worked.
I need help with hum
I've just hooked up a Panasonic DVD A120 to my TV. I've run the component video inputs into the TV but when I run the audio outs to my preamp (a Bryston B-60) I get a nasty hum. What can I do to eliminate this. Will Mondial's magic splitter work? This is my first foray into HT so any help is appreciated.
