"Best way to get rid of AC buzz/interference in speakers?"


  

          


I've managed to work around it for awhile but seems it's gotten louder lately....

it's definitely the AC current buzz coming through the speakers and it bleeds to the recordings. I spent a few hours last weekend trying to isolate it by unplugging/turning everything off...but it just gets lower when things are turned off and of course louder when things are turned on...

here's a good video that explains it well:

but don't think this applies completely here as my setup isn't as the diagram...

I think I just need a component that will go between the wall socket and power strip if anything like this exists (I've looked up a few but not sure which is best)

What do you guys use/do for this?

I'm sure ground loop plays a part here:

but all components are plugged into power strips that are plugged into the same AC outlet - not different ones as the you tube shows.

All audio is plugged into the PC via mini-plug/daisy chained

even when I unplug the audio cables from the PC I still hear the buzz

I separated the power cords from audio cords so there at least 2 feet apart from each other and the buzz got even louder..

wtf??

The only thing I can think of is to make sure that absolutely EVERYTHING including non audio equipment like your monitor/screen and computer itself is plugged into the same circuit. I've gotten a ground loop from something as simple as an external hard drive being plugged into a different circuit than the rest of the system.

Also double check all wiring - if your speakers are passive it's very easy to have a bad connection from your amp to your speakers. Buzz is usually bad speaker wiring and 60Hz hum is usually electrical ground looping.

If you are using a laptop make sure that any onboard microphones are muted as they will pick up a ton of computer noise.

I'm checking all that...

actually I cut alot of the hum significantly when I swapped out the cable going to my monitor speakers from RCA to XLR's....

still a bit of buzz in my smaller monitor speakers but I'm getting new cables for them as well...
