Radio interference in high voltage system


You mean, Ground loop humming, popping, buzzing in your speakers? Bypass the ground plug on your equipment and seperate the power cables from the audio cables.

I have a building to building PA system and in some building I'm getting AC humm through the speakers. Is there a AC filter out there that could eliminate the humm?


You´d better use a power conditioner, such as Panamax. Besides, it will protect the system against power surges and will eliminate the humm.

Loud Humming


Many times a "humming"sound is caused by bad signal, caused by things like, bad rca cable, bad rca ground from the radio, or even a bad ground in from the amp to the car.. Wiggle your rca cables at the input to the amp, and see if it changes the hum at all.. If not take a short peice of speaker wire, and wrap one side arrounf the outside metal at the end fo the RCA jack, and then touch the other end to ground, and see if that makes the humm go away. If the humm goes away at that point then you need to have your radio replaced, or repaired. if neither of these do anything to the hum then check for tight ground connection to the amp, and to the car..

There could also be a problem with the amp it's self, but this kind of thing is hard to diagnose over the web, so try those things, and let me know what happens..

Loud hum when I turn on power from the speaker


Disconnect the device (amp or TV) that is feeding the speaker system. Turn on the power and see if there is still a hum. If the hum is no longer present, then the hum is most likely from the source.

If the hum persists, most likely the power supply has failed, or the output section has a short. You should contact the manufacture for support. They will most likely recomend that you give the unit in for service.

I have a loud humm in my bose lifestyle 28 system


Turn on your bose so you can hear it hum. Go to the back of your cable box and remove the co ax cable connected to "cable in". If the humming stops, the sheilding on your cable is no longer grounded. Purchase MPAV800 or similar surge protector to run cable line through it and get it grounded.

Speaker system


This definately means that you have a positve and negative speaker wire touching somewhere. First thing to do would be to check all connections at the speakers and on back of receiver and make sure all wires are seperated. This is a common problem if two wires are touching each other. If you check all connections and they look ok and you still have same problem you need to start unhooking all wires and hook them up one at a time and turn on system. If it works with one speaker then try hooking up a second speaker wire and so on until it gives you protection message again. Basically process of elemenation. Once you says that protection message you need to replace the last wire you hook up all together as you could of damaged it when running speaker wire or it could be a defect in speaker wire.

Hum coming from speakers


Faulty wires/ connections are the usual cause of hums on speakers. Try checking if the wires are properly connected. If it still hums, try replacing the wires with a known good wire.
