One high quality product is the Magic Box . I've seen a couple of good reviews on it and would be choice for the best possible picture quality.

I had the same problem and I was able to fix it with the Xantech 63400 Ground Breaker . And this option is much cheaper.

Hey guys,
Great forum! I just found it today. I just got my 1050 last Tuesday. I had a ground loop hum coming from my sub also. I did what it says at this link and my hum virtually went away. Now I have to put my ear actually in the port of my sub (Paradigm PS-1000) to be able to hear any hum at all.

I thought I had wasted the $60 bucks on my surge protector (THEATER GUARD PRO) but twice now it has saved me. It solved the hum issue and before it told me my outlets were wired incorrectly...

Definitely a ground loop problem, I think it commonly happens when hooking up to TVs because they get plugged into another outlet or surge suppressor (often they were not installed at the same time.)

Saw this problem when connecting my Tivo (audio only) to my Outlaw 1050. Very confusing, since I even got the hum when selecting other sources.

My other thought is that the ground loop comes not from the power supply in all cases but sometimes is associated with the incoming cable signal. I have seen that in other (non-Outlaw) setups.

Fixed my group loop problem - added a MonsterCable surge suppressor with the Cable surge in/out, it immediately cleared up. I'm pretty sure it's a ground loop between the cable signal and the power outlet. Once I had them all on the surge supressor, it probably put them to the same ground - 60 HZ ground loop immediately disappeared.

People only see it on their sub because generally they have their crossover set to 80 Hz or higher.
