Check what Herman says above....most cable TV feeds into your home will ground the cable to the same earth ground(pipe) that the AC input to your home is grounded to. Many cable TV feeds have serious DC voltage on the ground, and thus my be placing a DC voltage on the ground pin of all of your homes AC plugs...causing hum/noise on your system...let alone reducing the overall capibility of your components.
Help I got a big time Hum in my system
I just put my HT system together. It consists of Aerial fronts Aerial rears and Aerial center and Paradigm 15 sub...power is Classe ca300 for the fronts Parasound 2203a( 3 channel) for the rears and center.The pre/pro is an Aragon
Soundstage....Cables are mostly Straightwire.
With that aside I am getting a loud hum out of all channels in all modes....it is always present even when the processor is off. It will get louder when I turn the processor up to about 60 per cent....but in lower volume settings it seems to bee constant. I do not have any power conditioners in the system at this time.....The outlets are suppose to be dedicated circuits.....When I have just the amps on and take off the interconnects to the processor it stops.....Is this a problem with the way the electrician wired my room......I need help bad Please!!!! Thanks
