The Portta version of this emitted a very audible high pitched whine--does this receiver make any noise at all?

I notice zero AC hum or any whine. I would use this again. I will pass on stay clear of tranmittion over AC wiring S/R units---I think Black Box was the one I used. It has a delay and gets hot.good luck

I've read other reviewers comments about exactly that, a high pitched whine like a camera flash charging up. All I can say is the one I got is perfectly silent. I keep it on my nightstand and have never heard anything.

This is a very poor receiver with terrible sound quality. I would suggest going with something from a name brand company.

If you're 100% sure it's not the source, then yes. I don't have hum unless I am on high volume but I have had a lot of source hum from my sound card. So check that out before shipping it off.

I had the same problem. There was some speculation that it was due to overheating. Because of this and another problem I had with this receiver, I returned it and got a Pioneer unit that I am much happier with.

Yes and I had to use it so I tested the system :-} I actually really like this receiver but I was having some issues with it. I was too busy to deal with it within Amazons return policy window and ultimately got an RMA from HK. I shipped my old unit back and they gave me a brand new unit in exchange.

Lucy, I found the source of my hum. I have Direct TV HD. I found that going into the menu settings/Audio/Sound Effects and turning that option off, I was able to rid myself of the annoying hum. The option has something to do with keeping the audio settings from channel to channel, while it is changing you hear dead air except for the hum. Nice and quit now. Love this receiver! Larry

I am not having this issue; the one I have works fine with no feed back noise. Try exchanging it. Sorry for the delay in responding.

I too get a low level interference noise from my PC. Ive tried different cables and mixers, some are better than others, but I cannot make it disappear completely because all of my cables ten to "run together" around my desk. That said shielding the signal wires from stray RF is your only option, OR turn them up really LOUD. Just kidding.

Just make sure you are plugged into a sub out port on your receiver i.e. bypassing the amplifier. Also swap the cable with any old cable to see if you hear anything. If that doesn't work you may have a dud sub-out port or a dud sub. If you do, I would recommend getting a replacement because I have had this sub for 6 months and it is fantastic for the price. Good luck!

I have the same version but with a metal chassis and noticed this whine. I'm going to look into a replacement. It makes the noise about 20 seconds after plugging in the power.

I never hooked up sound, so I can't speak to that aspect of the device. I think that this is a very old model, it's probably been sitting in the warehouse for a long time. I returned this model immediately after receiving it. It wouldn't power up, when it finally did the screen was obviously damaged - googling suggested the damage was from being too hot. Sorry, that's all I've got. It would be helpful to know what source you have it hooked up to and how you've plugged it in.

mine works great. it sounds like someone is in the room with me. you got a reject, send it back for a replacement.

Mine, too, made a loud pop every time I turned it on. However, it was working otherwise until it lost connection to the subwoofer and started making the clicking (or popping) noise every second or so. None of my ideas for addressing the problem worked except for returning the unit to Amazon, which I am doing.

I have had this unit for almost a year in live application and have not experienced any unusual noise or hiss. I am sure if the gain structure is wrong any unit could have the potential for noise. hope that's what you wanted to hear

Yes! I thought it was something in the old one going bad so I bought a new one and all was fine for a few weeks now it is doing the same thing. It doesn't seem to matter whether the power to the receiver is on or off. As long as the woofer is plugged in it will randomly start the feed back loop which can only be stopped by turning off the woofer. Sorry I don't have any answers.
