line level ground loop isolator

[B-52 Bass]

I was checking didn't see tread for this, delete if its already listed.

Do anybody use this connected to their sub or any part of your HT. I started having a humming sound coming through one of my subs last week Tuesday. Don't know why it started but I just ordered one from Monoprice.

I had looked up "subwoofer hum" and this item popped up to get rid of it. So i'll try it out hope works. Anybody have same problem or a better solution chime in....
