Denon AVR-1601 Receiver

When I plug in my receiver a humming noise comes through my speakers. If i turn up the volume the sound will drown it out. The lower the volume the more you can hear the humming noise.
P.S. When I Plug in my woofer it also makes a humming noise.

    I've got a Pioneer QX-747 quadraphonic that is pristine, with the exception of noise from the front speakers only regardless of the volume setting, or the input setting. How can I resolve this hissing noise?


    Is doesn't go up with the volume, and does not seem to be associated with any control or setting. Think of a hiss in the background of the front speakers, the louder the volume goes the more it drowns out the hiss, but it's still there.


    Help!?!?!?

I have a Denon receiver and I took all the wires out and double checked them and they are in the right place but the receiver keeps turning off. I get a loud humming noise sometimes when the wires cross...


There's a clue there. Loud hum and tampering with wires changes something. Disconenct all speaker wires and see how that works out. Then add one at a time.

I have a Denon Surround receiver, model AVR-1804 which manages our home surround sound system (6 speakers including a sub-woofer). When the TV (Visio HDTV) is turned off, but the receiver is still on, we...


Some kind of ground potential difference between the TV and the AVR or perhaps it's a badly shielded cable.

Considering the multitude of variations you may have connecting the TV video and audio to the receiver it's hard to pin it down, but try removing all cabling between them and that should silence the hum. Add any cable and see if it comes back. Disconnect it. Test each cable the same way. At some point a single cable might be implicated. Replace it.

Also consider routing of any analog audio cable near power cables, the TV or other sources of high voltage and magnetic fields. I have a known problem when my overhead dimmer-controlled track lighting is on. Food for thought.

The unit is in protect mode. It has detected a problem in the final output stage and has shut down to prevent further damage. Disconnect the speakers completely and try turning it on. If you still get the same symptom, the problem is inside the unit and repair is required. Usually when this occurs, the output transistors have failed. There will be at least 2 that need to be replaced. Figure on parts costing around $15-$25. Add in the local labor rate for the complete repair cost.
