Hey guys,
Heres my dilemma: my speakers have a very audible humming/buzzing that have been coming from them ever since I moved into my current house. I've tried some basic things on trying to figure out where its coming from, but so far no luck. Could use some suggestions.
First, heres my setup:
at the front of the room i have my AV gear:
Pioneer Elite VSX-91TXH receiver
PS3 Slim
Tivo HD (plugged into Antenna only, no cable from the wall)
HTPC
All of those are plugged into a UPS, cyberpower something, can't remember the model.
The receiver is in a 7.1 configuration, with the sub at the back left of the room (for reasons outside of this discussion
). The sub is plugged right into the wall, and the other outlet there has a power strip with my cable modem and router there.
At the back of the room is my Panasonic PT-AR100U projector.
Now, obviously the subwoofer and projector are placed on different outlets from the front of the room (and the sub/projector are not on the same outlet either).
I've noticed that the humming is worse on the PS3 than on the HTPC. What I've tried so far:
Powering off everything, running the ps3 and receiver into the wall directly, no dice.
Powering off and unplugging the subwoofer, nope (though that was a while ago, I may try again to make sure that I did it...)
I also want to try plugging in the projector to the front of the room for testing, though I'm not sure what that would tell me...
I've done some googling, and some people over on [H] mentioned maybe getting an isolation transformer like http://www.amazon.com/Tripp-Lite-IS2...g=hardfocom-20 That one, but I'm not sure if that would do anything for me.
Anyone have any thoughts on this?
