I have a sony sa-wms23 powered subwoofer, the problem with it (besides it being sony) is it makes a low buzzing noise for about 3 seconds then it will sound normal for about 3 seconds then continually go back and forth between the two doing this. What could be the cause of this? How would I go about solving this noise?

I think it being a Sony is part of the problem :D

Sounds like some hum is getting into the amp, might be AC hum or something.

Nope, nothing wrong with the "sub". How would I fix the AC hum? Isnt their a filter of some sort?

Well, probably some capacitors on the 120v power supply would help, but you'd have to take the amp apart and see. What about ferrite chokes on the power cable? That might work...

I think ill try a ferrite noise supressor on the power line, any other ideas on something I could try if that doesnt work?

I plan to, believe me. :D I guess ill try the ferrite filter, if that doesnt work ill come back and go from there.

It is some of a buzz than a hum. I dont see how the power company would be involved with the noise, care to explain?

Maybe your amp is set on Full or HP filter. Set it to LP if you are powering subs. I had this problem also until i started messing around with the amp.

When my cell phone is around my Logitech z-680's, they buzz and hum and crackle. When I move it 5 feet away from the amp, it goes away. just a thought

It's a home theater sub...the onboard plate amp is not going to have those options, as it's only designed for powering subs, and nothing else ;)

Try not having your cell phone around it.

Nope, nothing to do with a cell phone. Theres no phone withing 5 feet of it anyways. Only line is the internet line.

i have HEARD, i have HEARD that depending on the amplifier that you are using such items as high current equipment on 120v ac mains have a tendency to hum. that probably doesn't make sense at all, but it is just what i have read. something happens that the ac current drops and somehow the power company can install something to fix it. if this isn't a vague answer, then show me one lol, but it is just what i have read and heard about. since it probably will elude you, then i assume it isn't the problem.
