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

The Conext Link AD104 RCA Stereo Ground Loop Isolator is an excellent solution for eliminating unwanted buzzing or humming in your audio system. I connected it between my car stereo and amplifier, and the annoying background noise disappeared immediately. The installation process couldn’t be easier just plug it between the RCA input and output. The device feels solid, with a durable metal casing and good-quality gold plated connectors that ensure a stable signal and long lasting use. The sound quality noticeably improved once the noise was gone. While it might slightly reduce the bass in some setups, the overall audio clarity is much better and definitely worth the trade off. It’s a compact, lightweight tool that’s easy to hide behind your system, making it perfect for both home and car audio. For the price, this is a highly effective and affordable way to resolve ground loop issues. I highly recommend it if you’re dealing with unwanted hums or interference in your stereo system.

For the money, excellent. Does exactly what it's supposed to do. Immediately got rid of the humming sound coming from my television in my travel trailer.

There is no noise because there is no signal anymore. Straight up made my subwoofers not detect ANY signal. It would've been the same as just turning the subs off. Disappointing.

This worked extremely well, cleared a lot of the buzzing up on my old VCR immediately. If you're using a component to HDMI converter and have an annoying buzz in the audio, this may be the fix you're looking for.

'67 Camaro Big Block, USA-740 radio, Ocean budget amp, NMSD 6AL, MSD plug wires, high output alternator, battery in the trunk. These filters work... sometimes. I got two, for a 4 channel amp. At first, these did nothing. Then, a few seconds later, all the hum was eliminated, completely. It was perfect! I had found stereo nirvana! Then, the next time I drove the car, it reappeared, but not as loud. Nirvana reduced to adequate. Before, I could hear the whine over my big block Chevy with 40 series Flowmasters. That's a lotta whine! Now at least, I can't hear the whine until I slow to an idle. Therefore, since these did work exactly as I wanted, at least once, I think they deserve a positive rating. So, did they work, then quickly degrade? Or do I have other issues in my stereo wiring setup. Probably the latter. So I'm giving these a good rating. The coiled yellow wire was my useless attempt to route some RF noise to ground.

Works as advertised - took care of ground loop.

Got a new amp to drive my computer speakers but would get an incredibly annoying buzzing or hum when the GPU was doing something complex. I was afraid I spent so much money on a graphics card only for it to have a problem with the motherboard causing noise to come from the aux output. Was looking up causes and solutions on the internet and heard about a "ground loop" but wasn't sure if that's what was happening here. Figured "for that price, why not give it a shot". This little guy works miracles. No perceptible change in audio quality, and that buzzing noise just VANISHED. I guess it was a ground loop after all. Crystal clear sound, and I didn't have to crank up the volume after plugging it in. I can't speak for its ability to eliminate alternator interference, but as far as being a ground loop isolator, it is fantastic. Would recommend. Couldn't be happier.

It worked, but at the expense of most of the bass sound! Not good!

I bought two of these for my Audi (w Bose speakers) that I installed aftermarket head unit in. Completely eliminated the high-pitch generator whine I had before, without impacting audio quality or bass at all. Note that you'll probably need more than one of these, for my car I needed two, one for the front speakers and one for the rear speakers. Check how many RCA cables to the speakers you have behind your headunit before ordering.

Après avoir tout essayé et en dernier recours, j’ai connecté cette boucle de masse sur les câbles RCA entre mon autoradio Pioneer MHV-S420BT et mon ampli Crunch 400watts. Ce système de boucle magnétique fonctionne super bien sans dégrader la qualité audio. Super rien à dire!

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

I installed an aftermarket CarPlay thing and was getting terrible alternator whine from the stereo when using it. I could have dug around in the dash and spliced into the head unit harness for a common ground but this ground loop isolator did exactly what it was supposed to do. After adding it on the audio output fro the CarPlay unit the annoying buzz was gone. No noticeable drop in volume or sound quality with this simple fix.

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.
