I have not experience any problems with this power adpter. Can't help. Follow David's advise.

Is the hum coming from the power adapter itself? If so, it might be getting ready to go bad. Replace before you have a fire. If the hum is from the speakers, re-post and I might have some suggestions for that as well.

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.

Are you sure it isn't the subwoofer? It stays on all the time even when the system is turned off and produces a low level hum, constantly. That seems to be the norm for all the subs and the Onkyo receivers. I was surprised to walk into my media room and hear the hum coming from the sub and the system was turned off. Sub is always in stand by. Just a thought.

I had the same problem, I had to move it, it was getting AC noise from the wall outlet, make sure all your power cords are away from it. (good luck)

A replacement cable may be needed; make sure it's balanced otherwise you'll keep getting a humming or buzzing. Best suggestion I have, always a good place to start though.

I use it to record through, and can say I have no evidence of a hum. A hum is usually a sign of a ground loop, so I would suggest trying an decoupler (hum buster) if it persists when connecting your devices.

It is a low pitch hum. Usually mine is on low and I get used to it and don't really notice it. Higher speed is more noticeable, but still more a medium pitch, not high-pitched.

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.

Whenever you get that dreaded hum, be sure to check your ground connections.Could be something as simple as trying out a new instrument cable.I've even had some brand new cables with an open ground.You may have to re-solder the ends.

No, I don't have that problem. I never noticed a fan running until I read this email. Now, I can hear a slight hum occasionally. But nothing you should ever notice. Yours is not right.

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 get the same thing. Was considering returning the unit because of the aux input noise.

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.

I just bought it & have Windows 7. It works fine except it has a hum that I can't get rid of. I've played with the gain button & the mic volume, but it's still there. Any suggestions?
