Conext Link RCA Stereo 2 Channel Ground Loop Isolator Signal Noise Filter Suppressor Reducer Alternator for Car Audio Stereo（13600）

I recently managed to secure a Roland MC-505 Groovebox but I had a really annoying low frequency hum coming out of my amplifier through the 505. I connected up the ground loop & it totally eliminated the hum from my Groovebox. I highly recommend this product if you are using old school synthesisers through an amp like I am. Brilliant but simple solution.

did the job one one car, did not on the other therefore hit and miss. The vibe one did not work on either of the cars!

Amplified the hum I was trying to eliminate

I've always had this annoying computer noise from my monitors connected to my Focusrite scarlett. Using headphones I get no noise, but when I connect the Rocket 5s I get random high frequency hissing. I tried most of the suggested tricks but none worked. I was 100% sure this was computer noise because other devices connected to speakers are fine. I did not hold up much hope for this device as it was cheap but to my surprise it worked great! Noise completely gone.

then this product works like a charm, however will reduce your bass, had to increase the subwoofer gain which for me was not a problem

Had to go from balanced to unbalanced connections to add a small subwoofer and got static hissing from my studio monitors. Saw this and though why not try it.Added it in between the audio interface and sub made it a lot worse but then changed it from sub to speakers instead and it fixed the static. Definitely reccommend giving it a try. Nice affordable fix.

The device is compact and requires no power. I am not an expert to review this and was not at all sure the issue in my audio system was a ground loop, but duly inserted into the audio lead, a background rumble noise is now gone or substantially diminished.

They worked a bit but not fully effective then the end snapped in my amp and has made it defunct not too impressed
