How do I reduce my feedback?

[gazcat]

I have some infinity beta 50s and a dayton 15" titanic subwoofer. They are powered by a harmon kardon 3485 receiver with high gauge speaker wire. Subwoofer has a monster cable.

Why is it that I get so much feedback? its almost unbearable and makes my speakers suck. i dont even turn my subwoofer on most of the time cause its so bad. and gets louder as i turn the gain up. speakers have it too

how can i fix this?

From my recollection, this sounds like it might be caused by a ground loop issue. I'm no expert on those, but search for them on here (or the web) and you should find some good info. Others here have some great knowledge about those.

I think you have described what is going on incorrectly. Feedback, is usually caused in PAs with the microphone feeding back to the system, and is a high pitched howl.

What is the sound you are getting? If it is a hum or buzz it is likely a ground loop. We then need to know all equipment and cabling, especially mains plugs and whether they are three or two pin. Special note must be made of cable boxes and their connection to the cable system. In fact if you have a cable system, disconnect it from the cable outlet and see if that stops it.

Yes it is definately a hum or buzz... just like "mmmmmmm". Its plugged into a power strip attached to another powerstrip that is plugged in the wall, could that be it? Everything is two pin and the power strips are three pin

Again, not enough information. This is a ground loop, and there must be at least a couple of grounds in your system currently. I can't help you without knowing exactly ALL the equipment in your rig, and the exact details of EVERY CABLE and where they go from and to.

This includes all cables, the details of your TV hookups, all cable boxes and inter connects. Everything must be described and accounted for in the greatest detail. If you don't do this, or leave out the slightest detail, you are beyond help.

Why do you have two power strips daisy chained and are they surge protector type? Also read up on these forums about ground loops please, so you understand what they are.

Can you just tell me what to look for? I got a bunch of cords

No! Because it is the cord you don't tell me about that will be the problem. A ground loop is a voltage between grounds. So unless you tell me your set up, I can't tell you how to go about isolating the problem.

The other issue, a jumble of cables contributes to this. A logical neatly wired system goes a long way to preventing these problems.

Since your system is at this time effectively useless, I would have thought it would have been worth your while to map your system and post it, so we can work to correct the problem. If that is too much trouble, enjoy your buzz. It would drive me nuts.

First of all I wouldn't daisy chain power strips, too easy to over load a circuit. You would also be advised to buy surge protectors instead of powerstrips. Basic ones don't cost much more than a power strip would. A surge protector that isolates the individual plugs from surging on each other is best.
Under the deals section there is a link to a surge protector/power conditioner that many folks have had good results with.

Get rid of the daisy chained power strips and clean up/organize your wires for a start....
