Hum problem

Hi All,

I need a little help. I moved to new house and I love it, but during the day my system has annoying hum in it. I don’t hear it in the late evening—just in the day.

I have everything plugged in to a Monster Power HTS 2000 Power Center, but it doesn’t seem to help. FYI my system consists of a Rouge 99 preamp, a Bat VK200 amp, Cary 303 CDP.

Any suggestions?

The Mondial Magic Box is a ground break for the cable TV.

Drop the ground. A couple of cheater adapters(3prong male to 2prong male)will do it. Most any supermarket or drug stores carry these devices.

Thanks for the suggestions. I have a couple of questions. On what do I lift the ground? My TV has a two prong plug. Also, where would one pick up a mondial magic box?

Thanks again

If your amp and preamp has XLR balanced imputs/outputs try using them. I had a hum or buzz problem that nothing I tried would fix (including sending my amp to Pass for reinspection). The balanced interconnects immediately fixed my problem.
