Simply disconnect your cable wire from the cable box and you have no more hum. I nearly jumped for joy when I discovered that. What the heck is a Rolls he Hum reducer? How much does it cost? Where can I get one?
Here is the link........http://www.rolls.com/rollsproducts/. Just look up HE18. Works great, but make sure you put it between the TV out and pre-amp in, not at the end of the chain between the pre-amp out and amp in, as this will effect the sound of the entire system. It's basically a isolation transformer.
