When I hook my PC audio into this device I get a hum.Is there a way to fix this ?

If the PC is a desktop with a three-wire AC cord, you likely have a ground loop (especially if TV audio is also connected). Try inserting an audio isolator between the switch and the PC; search for Amazon ASIN B0009O19LQ to see an example.

You might try re-routing your speaker cables through the normal maze that collects behind most computers

I don't know. All I can tell you is that I have a tv, computer, two stereos and dvd player plugged in. If I connect any one of the to another or turn all on at once I get no hum or static. The volume is a little reduced with each button pushed down but no other issues. It shouldn't matter but maybe a shielded cable? I used to have an old computer that produced radio frequency interference. It made static on the older tube type television if it was close to it when I connected cheap audio cable to it.. just throwing that out. Good luck.

The manufacturer can give you the method to resolve the hum problem with add on devices.

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.

Thanks very much to those who offered suggestions. Everything was fine with the wiring. A phone call to a Sony tech resolved the problem, which was found to be my selection of HDMI Passthrough to "ON". As such, the receiver remained partially powered in Standby and resulted in the hum. Re-selecting HDMI Passthrough to "OFF" cured the problem.

we are not using it to power audio equipment so i do not know if it will produce a hum in your equipment the unit itself is quiet I know some supplies do hum but the one we have is quiet

The hum might be due to a ground loop. This problem often happens when you interconnect devices via RF/audio/video/etc. cable that are plugged into electrical circuits with different grounds. To troubleshoot this, try disconnecting FM antenna, input and/or output cables from your receiver. Assuming that you have any kind of cable connecting the TV to the receiver, also try removing the RF cable from the TV. Cable TV hookups are reputed to be common causes for ground loops. If the hum goes away with a particular cable removed, search online for a ground loop eliminator device for that type of connection. An inexpensive audio ground loop eliminator is available at RadioShack stores; higher-end audio ground loop eliminators are available online. Cable TV ground loop eliminators are available from online sources. For further information, search the Web for the words "ground loop". Hope this helps! Dave

it solved my humming problem when i used 2 or more components plugged into my receiver. but when i got a more powerful amp i didnt need it. i would try it...you can always return it.

Check your settings and make sure audio output is set to displayport or HDMI instead of computer speakers.

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.

Mine has a slight hum. Some kind of ground loop, I guess. I'm using a 3-pin to 2-pin adaptor on the power cord--the hum is much worse without it. I've tried both the balanced and phone plug inputs (with RCA adaptors)... no difference. I haven't tried breaking the ground on one of the input cables yet.

Yes there is a hum (slight). What I hear is constant; no matter what volume I am set at. I actually had to exchange my first set due to amplifier 'popping'. Again, volume setting did not matter. I have decided not to let this hum problem bother me because it is inaudible when something is playing.

It produces a low hum. It may not be enough noise if you are in a fairly noisy location, though.

I found that making sure there was no interference from any other electronics nearby helped. Just experiment with moving the unit, the input cable, and the source of your sound (whatever you're broadcasting) around until you find the sweet spot. I've got virtually no hum now, but occasionally I'll hear some and invariably find that someone has moved one of the elements around. Once I put it back where it belongs, no more hum.

I had the same trouble. It worked once I downloaded the driver: http://www.behringer.com/EN/Products/X2222USB.aspx under downloads.It could also be a ground loop that is causing the hum... are you using a laptop or a desktop?

I use mine to direct insert my guitar and keyboards to my computer. I have not noticed any "hum" in any of my recordings. I haven't use channel 1 (microphone vocal), so I can't help with the phantom powered channel.

No, I have not had that problem. The only problem is an occasional hum in the speakers.

I too have a hum at "quiet times". Which device menu are you referring to? The Onkyo Receiver or your Satellite Receiver?

Mine does not hum, I use it as an automatic transfer switch in the living room, it's been on 24 hrs a day for a month with zero noise. I would return it and try another one.
