How do i take out interference in speakers from HPS on same circuit?

the title pretty much explains it. ive got my whole room wired on the same breaker so i cant use an extension cord or somethin.

is there a device to plug in between the HPS ballast and the wall plug that mellows out the signal to what it should be?

ok so ive realized the ground loop isolator isnt whats gonna fix it. the AC adapter for the speakers doesnt even have a grounded plug haha

also the noise sounds like static

anyone got any ideas? is there something i can put between the speaker plug and the wall that makes sure the signal is correct, before going into the speakers?

First off, it isn't your speakers I would guess..

I would imagine it is your amplifier that is responding.. the speakers are a byproduct.

Have you tried isolating the amp, moving it around? Are there any other sources by it to exacerbate the situation, like TV's, floro lights and things like that in addition you might be able to isolate.

But then you say 12v dc.. which leade me to believe they are powered computer speakers, and those should be fairly well shielded.

There are LINE CONDITIONERS .. http://www.graniteaudio.com/zero/index.html

Or less expensive gadgets that claim to help http://www.amazon.com/PS-Audio-Noise-Harvester-suppressor/dp/B000Q7SCWA

If it were me, I would be inclined to start 'flipping' other plugs in the house as well.. you might get lucky and clear some leeway in the circuit thereby suppressing some of the noise.

Good luck~!

guess i didnt explain the speakers enough. they are a 4.1 home stereo speaker set, setup to plug into my computer.

when the HPS is off, the speakers work totally fine. no unwanted noises at all. im pretty sure its 100% the light ballast thats causing it. my tv and other stuff dont seem to affect it

I bet the problem is being caused by your magnetic ballast in your light. The only thing you can do is move them a little further away outside of the light. Speakers are magnetic and can be effecting by the magnetic ballast.

the problem isnt the magnetism. the ballast is sending a static signal down the AC lines in my house. apparently my computer speakers are the only things affected. my tv speakers dont do it(thats probly shielded though)
