If you have a powered subwoofer, you could try floating the ground. Mondial sells what is called a MAGIC box, which is a ground isolating unit for video systems. The costs is around $100 if I remember correctly. This might be worth a try. Good luck
Cable TV / Subwoofer HUMMMMMMM
My HT system works fine until I connect the Television cable to my system. I get a terrible sounding ground loop hummmmm. I have unhooked and hooked up each component and isolated the problem to be between the subwoofer and the cable signal. If I disconnect the subwoofer the hummm goes away and I can enjoy the cable TV. If I disconnect the cable I can enjoy my subwoofer. Once the cable is disconnected I enjoy using my sub with my DVD, VCR and CD inputs, its just the cable signal that screws things up.
So WHAT is the problem, it is driving my nuts disconnecting and connecting the cable and subwoofer. PLEASE, all help his appreciated.
My systems is as follows, A/V reciever Yamaha DSP-A1, Sunfire True subwoofer, Monster HD2000 SVHS interconnects, AQ ruby audio connects, Aerial 10T mains.
Thanks
