Humming noise

Possibly a bad cable or bad ground or bad outlet?. Easy solution, try a different outlet and see if the hum still exists. Also, make sure your speaker cables are NOT run parallel along with, or close to any power cables, Speaker wires can and will pick up AC "Humm" noise.

Receiver humming

Have you tried unplugging the Receiver from the power outlet and plugging it back in? Is your Receiver a service providers set top box DVR? It sounds like you may be hearing the Hard disk drive spinning on and off. But that's all I can tell from the description. Hope this helps.

Speaker humms only. what causes that?

Incorrect connections or volume settings.

• In powering up, mixer first then amp

• In turning off , amp first then mixer

If hum still persist, without the mixer connected

then speaker amp may need servicing.

Sub has started humming with amp turned off. just turned on at wall switch.nothing running

If the hum is from the back of the unit around the amplifier, it may be the transformer. It could be that the mounting is loose.
It could also be that the transformer is going out.

Disconnect all the inputs to the unit, Still hum?

If the hum stops you have something causing noise to the input.

If you have it on a switched circuit, try moving the power plug to a different outlet that is not on a switch. If hum stops, then you have something on that circuit causing the problem

if all inputs are disconnected and it still humms good chance it is the transformer.

If the drum is not turning and the hum is a nice quiet hum, then the belt on the drum has broken. The hum you hear is the motor turning without the belt.

If this helps you, please select YES to one of the first two ratings questions. Thank you, and Good Luck.

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.

Acoustimass Subwoofer has a low "hummm" sound when turned on.

Sounds like an inadequate ground wire in the signal cable. You may have to replace the cable between the reciever and bass module. It also, however, may be IN the bass or reciever module.
