rollsHE18 Buzz Off 2-Channel Hum and Buzz Remover with 2 RCA Male to 2 RCA Male Dual Audio Cable 3'

If you have a true ground loop issue, this product is very versatile given its variety of inputs and outpus, and provides highly effective ground isolation with its internal coupling transformers. Solid build, easily readable graphics for my aging eyes, and it looks nice to boot. Highly recommend.If your hum is due to other sources of interference, this won't cure it.

I had a buzzing sound when I connected the monoprice 300 watt amp to my Onkyo receiver. The whole balanced vs unbalanced thing. This Buzz Off eliminated the buzz completely. I used the supplied RCA cable and a RCA to 1/4 TS plug. The signal is attenuated slightly. Very happy with the result. The buzz was loud enough to be annoying.

Wanted to use this device with my guitar amps. It actually ADDED more noise and hum than I’ve ever had before. Returned.

Bought this to get rid of a buzz on my receiver when playing records. I tried several other products trying to save $$. Bad idea, this really worked. Plugged it in and the buzz went away. Money well spent.

Did not work for my application. Was able to return for a refund. Good transaction all the way round.

It helped reduce the buzzing/humming/popping coming from my studio monitors plugged into my computer. I added in the “BESIGN Ground Loop Noise Isolator“ which is just $10 and that did the trick! Kind of disappointing that it didn’t work on it’s own since it’s so pricey, but together these guys made reduced the static noise to almost zero!

I had a nasty hum between my record player and my receiver. After testing cables and grounds and a bunch of other potential causes, I finally caved and bought this guy. I'm so glad I did, it fixed everything.

We were having a problem with the sound system at our church causing a 60hz buzz when piping the sound into our streaming computer. This filter solved that problem!
