can this unit stop the hum interference u hear on a stereo system??very annoying noise/it comes from my equipment having to share the same wall outlet

Also, if possible only use equipment with a grounded 3 prong plug. Without the third ground connector on the power cord the equipment can't be properly grounded and so ground loop hum will be harder to avoid ...

i doubt it. from what i know having your equipment plugged into different circuits would only make the hum worse. in any case if your equipment hums it is probably not worth spending this much money to fix the problem. good equipment doesn't hum no matter where you plug it in. i suggest getting equipment that uses balanced ( XLR ) or digital ( Optical / Coaxial / XLR ) interconnects. Regular consumer unbalanced analog technology is inherently inferior and was never designed for high performance.

It doesn't on mine. I use this in my stereo and can hear a fairly loud buzzing in my speakers. You'll want a power filter of some kind or conditioner of sorts. I hooked the same equipment into an ethereal eso-1 in wall conditioner and cut the noise down tremendously, it was still there but it definitely helped. They've put the rice of these up to $112 a piece on accessories4less.

Yes. I use two of these to power my home music studio. Along with two 8 in Mackie studio monitors, I also have a KRK subwoofer plus two LCD display monitors (HDMI & DVI). This type of connection is more than enough to generate interference but the ISOBAR eliminates this with no issues.

I can't say for sure, but I know on my setup at least, there is no interference between devices. And I use 2 guitar amps and a gaming PC on mine.

I have had no interference at all and would highly recommend this speaker wire. I use this to connect my Bose system and my Definitive system and have nothing but praise for the quality and clarity. Hope this helps you.

I not totally sure, but I know if there is humming you have some electrical interference. The cables are possibly too close to the conduit in the walls or some other issue. I've had no problems with my setup, but when I turn my microwave on the sub hums. Not a big deal for me since it's not used much. So it's worth a try, if not return it.

At low volumes it is not very noticable... but if you crank it up then turn off the source of the audio (like turning off your tv) leaving the sound bar on...then the hum is bad.

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

Have you noticed if yours hum? I'm wondering if sinking the box into the wall- as you did, will help decrease the buzzing sound they emit. Thanks for any insight.

What you are referring to is most likely a phenomenon called "ground loop" or ground loop noise. This occurs when two or more items use the same ground arriving through different paths or it may also be EMI (electro-magnetic interference) from the various wirings around it. The easiest solution to get rid of it? A ground loop isolator works wonders and in this particular case there are ones available that require no special modification or installation, they install basically "in line" with the aux cable! I found one on Crutchfield and also on SonicElectronix (eBay as well) for less than $20, although I have yet to find this particular style here on Amazon. http://www.sonicelectronix.com/item_8987_PAC+SNI-1-3.5.html

I had surround sound and two of the 7 speakers hummed when I put the Direct TV HD in "pause." To fix this problem go to the Direct TV remote, setup, settings, audio, and turn "on" dolby digital. Mine was off and caused the hum!

Only thing I could see that would possibly interfere with doing that is the wireless sub. I would contact Polk and see if is possible that there may be interference. Other than that I don't see an issue.

I don't think I've heard any on mine. If you are hearing the hum while using the RCA jacks then maybe trying unplugging it from USB/have the turntable and speakers on separate outlets. If you are hearing it over USB then maybe just try the same isolation but between the computer and the turntable.

Could be a defective unit. Mine will sometimes make a very slight hum (ear right next to the unit) but even when I'm lying in bed sleeping other than the reassuring click that it turned on, I can't hear the hum. I also am only drawing... ~11A on the heaviest circuit, if you're pulling more than that it could explain a louder noise

interference of some kind or the speaker wires aren't connected correctly, or may be loose. I hooked ours up the way the amp I replaced was hooked up and the Pyle didn't work. Turned out to be much simpler. The second configuration I tried hummed and the sound was staticy. I think I have all 6 of our PAs combined to 1 set of wires and on one speaker connection and it has worked perfectly all summer. Hope that helps.

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

Thank you! I finally solved the hum problem by plugging the iMic into "Line Out" on my amplifier instead of directly into my turntable. The hum disappeared! Hope you got your hum solved, too.Maria

Radio shack also sells ground loop.isolators or you can build your own from a 1:1 transformer this should also fix the hum as well.

Also, Jeff: Even after all the electrical questions are answered, this still makes a low level hum which might be annoying. Having tightened all the external screws on mine, the hum was far less but could still be heard during the silence between musical tracks or even with very quiet passages.
