Ok I have 2 Pro Dynamic TX1200 speakers set up in my front room. http://www.prodynamicsusa.com/txspecs.htm These are powered by a Gemini Amp and controlled with a Gemini Pre-Amp. The problem is I have this constant feedback in the backround. If I turn the gain up though the feedback is lessened by a bit. I tried going to bestbuy and getting one of those powerstrips with the audio filters and that only helped a tad. I have had this set up in at least 4 other locations with no feed back. Here in my new house I just cant seem to get rid of it. I have tried running the wires every which way without any help. Anyone have some ideas what it could be or what I could do to get rid of it.
