Help! My speakers are buzzing (1 Viewer)

[Haris Ellahi]

My speakers have started buzzing quite loudly. Before, you could only hear the buzz if you put your ear right next to the speaker but now it can be heard from the seating position (and I haven't changed anything). I've noticed that when I turn on my A/V receiver, the buzz is quite faint/quiet but as soon as I turn on my plasma TV, the buzzing gets a lot louder. The buzzing is not volume dependant.

I have connected all of my equipment (plasma TV, A/V receiver, and DVD player) on an extension socket (where the extension socket connects to the power outlet and offers four more outlets for connection). Could my extension socket be the culprit? Should I try investing in a power conditioner?

You basically have everything running off a single electrical outlet - the one your "extension socket" connects to. So yeah, this is definitely an electrical problem. Not to mention a fire hazard.

Could be a grounding issue. And while you say you haven't changed anything, something obviously has changed. Have you installed any new appliances in any other rooms? A mini-fridge plugged into an outlet on the same household circuit could definitely produce a result like this.

You don't necessarily need a power conditioner, but you should certainly get a couple of good surge protectors or a couple of small UPSes, plug each into a different power outlet (preferably on different circuit breakers) and divide your equipment between them. Make sure that everything is properly grounded. That should cure the buzzing.

Regards,

Okay, I "blasted" some music today (2-channel music CDs) at very high volume for about 10 mins and now the buzzing has absolutely disappeared! Now I cannot hear any buzzing even if I place my ear right in the tweeter! Even when turning on the plasma TV causes absolutely no buzzing.

How is this possible?

Dirty power, ground issues, overloaded circuit, other loads on the circuit and more.....basically everything Joseph said.

Did you check any of those things?
