Axiom Home Page Forums General Discussion Technical Questions Buzzzz from speakers multiple subs.

Well, I am finishing up a few minor things and should have my remodeling of the Plex done soon. Hope to take a few snapshots asap.

Anyway, last night I was taking a few initial sweeps from the primary seat to get an idea of how each of my subs individually (distance/levels) will have to be set before doing all 8 sweeps.

Whenever I plug in my 350 I get a buzzing sound coming out of all my speakers. It is loud enough to be annoying. I have a good idea that it has to do with it being on a different circuit than the rest of the equipment, but I have no options. Eventually, I might bring down my other 350 to have both of them on the opposite wall of the 600 to follow Toole's papers. (2 350's opposite the 600)

When I enclosed in the theater portion from the rest of the recroom, I added a rear and side entrance wall. I was unable to tap into the existing HT circuit, and had to extend off a circuit that powers the rest of the recroom. If that tells you anything.

Anyway, I found an article that Alan did about eliminating this annoying buzz and will try to troubleshoot, just looking for ideas.

I don't have satellite/cable in this room yet as the article mentions, but do have a HTPC that is hooked to an external over-the-air antenna, don't think that would be the problem.

Here is my setup for now, still need to bring the Bluray player back down that is being used upstairs...

Denon 3808ci
Sanyo Projector (hooked to HDMI out on Denon)
HTPC (hooked to HDMI in on Denon)
Outlaw 7700 amp (hooked to Denon preouts using RCA)
Axiom EP600, 80's, 180, Qs8s (hooked to speaker jacks on amp)

Tripplite HT Powerbar Surge/Isobar - all equipment is hooked to this, which is hooked to outlet on 20amp circuit. The EP600 is plugged into an outlet on the same circuit in the room.

So, I still think it has to do with the 350 being on a different AC circuit. Just trying to figure out where to start. Maybe one of these gizmos that Alan mentions in his article will help.

thanks for listening, Randy
