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

You can get a ground breaker from Xantec for about 8 bucks, it's specifically designed for cables coming in from satellite or cable tv cable.
Ground breakers are fine if you live in a rural area, or do not have sensitive video equipment... I used to use the ground breaker until I got a big screen.... What happens in an urban area, you will get other noise problems with a ground breaker unless the distance of cable after the ground breaker is less than the length of 1/4 wave antenna. With my setup, There was no option other than to fix the issue... Yes - 2 weekends of troubleshooting and refurbishing grounds everywhere that mattered... Now my system is dead silent on the audio & perfect on the video.
hello is there a alternate way to ground the cable TV signal instead of grounding to the same point as the house Electric ground?
