Along the lines of Jvia, perhaps your system has a ground loop caused by more than one three-prong AC main cord. Since individual components are connected to each other through their interconnects (and you say when you remove interconnects the hum stops), only ONE component should be three wire connected to the AC receptacle or line conditioner. All other components should be two-wire connected only. I purchased some two-prong ground adapters from Radio Shack and attached them to 2 of the 3 three-prong plugs in my system and eliminated the ground loop and corresponding hum. Of course this will only help in your case if you have more than one three-prong plug in your system. Good hunting otherwise.
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
