It just started recently. I can pick up very strange noises on my center channel. It sounds like someone with a cell phone with the two way feature. Sometimes it sounds like weird beeps and such. It's very prominent too. When I mute my receiver, I can still hear the sound. I just replaced my cheap KLH center because it sucked AND I heard the same kind of interference on it. So I got an Athena that sounds much better but it still picks up interference. Can I fix this?
