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

It work in my car very well

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.

Does absolutely the opposite of what it should do

Worked a treat to kill an annoying noise, definitely worth the money

It's really helped with reducing interference in a Campervans audio system but the sound quality was compromised. There was a decrease in the higher frequency levels, the sound isn't as clear as it used to be.

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

If you have an annoying buzz in your headphones, or speakers, this could be caused by a bad earth connection. My property has the worst grounding that I ever encountered, and these removed the hum encountered between my audio equipment, and with my pc. Hum all gone, with no loss of signal quality. Job done. :)

Really impressed by this! I was getting interference through my speakers from my pc and after some help with Gemini to diagnose the issue this was recommended with the issue being electrostatic interference from the gpu. Now there's no interference at all!

if you have a bose audio system then this is for you. my car has a bose audio system. i changed the radio on an audi a3 8p to a 2din android radio and got generator noise and white noise (like from an old tv) i used these two filters and the noise went away so if you have a bose then try

Fonctionne très bien sûr sono voiture avec amplificateur

I disturbi li elimina completamente, ma il livello del volume e la qualità dell’audio purtroppo scendono un po’.

Tog bort 99% av allt brum och störningar jag hade i min Audi från Android HU till mitt Bose i bilen. Mycket prisvärd.

Had noise (screeching) coming from my audio system whenever the GPU on my computer was being utilized. Google searches recommended a ground loop isolator, and this was the cheapest I could find on Amazon. As soon as I plugged it in, the problem was solved! And no change to audio quality as well from what I could tell.
