hello I have a high pitch feed back through my speakers, The set is a remote avr closet,

I was very careful to keep power away from the speaker wires as i could, right now only the FR FL Center and SUB channle are hooked up


how do i track the source of this feedback down? eek.gif

Unplug one device from the receiver at a time until the noise goes away.

Is this a new setup? If so, what speakers do you have? You may just have VERY sensitive speakers and the noise floor of your equipment is high. If this is an old setup and it just started happening, what changed?

What do you mean by feedback? You'll need to describe the symptoms better. Just because there is a high frequency noise does not mean it is feedback. It can be feedback if you are feeding a preamp output back into an input. Does the problem exist with digital sources? At all volume settings? With speakers off using headphones? All the speakers?

hi all im sorry i didn't get an email

I notice the issue after i moved

it happens on any input source ( i only have 2 HDMI the DTV and blue ray)

I just hooked up the systtem from 3.1 to 7.1 and it is in all speakers and the same same sound in each

I have tried it pluged into my UPS (bother battery backup and surge) and into wall and into that will with a filter on it, I have tried different plugs also

it seems to get worse since i hooked up the 7.1

it does not change with volume

its high pitch and varys up and down a little

i hear it if i mute also

If you hear spurious HF tones with the AVR muted, it suggests a failure inside the AVR. If you disconnect every source cable, and every speaker but one, and the noise remains, it's time for a trip to the service shop.
