Using this power supply, I am getting loud hum(over audio) from the AS501 speakers from original monitor, and now located beneath a new LCD monitor.

My apologies for the long time to respond to this, this is the first time I get asked a question through Amazon. Anyways the power supply worked great for me but the problem could be from the power source or the speakers. So try to test your speaker with the same power supply at another location in your house or a friends house maybe with a portable mp3 player. Also if someone else has the same speakers borrow the power adapter or swap your friend's speakers from the monitor just to test it.

I use a 35 ft. VGA/ audio cable from my PC with a PC/TV tuner, using it as a DVR with Windows Media center to my Big Screen and also use my Monitor with a VGA Powered splitter. Using a powered splitter because with out it I had lines on the TV, the powered splitter took care of it, but I also have a hum or feed back sound, can't explain it. It may be the same sound you have, if you get a answer to your question please let me know at DWB@socal.rr.com, Thanks Don

You will have a hum sound unless they are grounded somehow, these are great speakers!

Yes. That is exactly what I purchased this for. That annoying Humm is now gone. I was getting that Humm from my home theater sound. It worked perfectly. I'm a very happy customer.

A hum that you can hear is normal. If it is loud, something is wrong. If it is noisy without a load connected, I would replace it. Are you sure you have not overloaded it?

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.

This is 100% incorrect, something Monster just made up to sell more cable. If you're getting hum then it's something else in your system.

If you're carrying audio over HDMI, your connection is fine. The cause of the hiss is either your receiver-speaker lines or the audio settings on your computer, including drivers and software. If the his happens for other HDMI audio sources (e.g. gaming console, BluRay player), then the problem is your speaker connection. If it's only your computer, Try updating audio drivers, different audio programs, and verify that the sound card and receiver are using the same audio format. Good luck!

Try putting a barrier between the audio or speaker cable to your power cables. Or don't let both cables, run side by side for it will create interference, such as distortion noise. Using a power conditioner helps a lot.

You're experiencing ground loop hum. Try using batteries only. If you still here loud hums, send it in for repair.

Probably a connection issue with one of the components hooked to the TV (mine happened to be a Sony DVD player...) removed that and the hum went away. Gave me an excuse to get a progressive scan DVD player... hooked it up and still no noise. It took me a bit to narrow it down, since I've got so many console systems. ;)

I am getting the same thing. It is a buzzing/loud humming noise. Anybody know if this is a defect or if something else can be creating this?

The power supply itself dose not make any noise, but I'm don't know if it would induce a harmonic noise into your stereo equipment. Especially if you are using amplifiers.

Yes, as the extermal speakers i have connected to the pc supply audio and the monitor speakers appear off.

Its a 500 watt power supply you could probably google it. It shouldnt have much effect espically if you are already running a desktop.
