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.

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.

These work great. After swapping my car speakers from the stereo to an amplified setup fed by RCA cables I got really bad alternator wine that got louder as you accelerated even with volume at 0. Added this between my RCA and amplifier and its crystal clear. No more annoying high pitched squealing. Did not seem to affect the bass on my speakers too bad either but I wouldn't use these for a subwoofer.

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.

I couldn't get my home subwoofer to quit making humming or buzzing. I move replaced all audio cables to no avail. Then I put this baby inline with my subwoofer and low and behold no humming or buzzing now!!!!! Since my sub only has one input. I wasn't sure if this would work, using only one side of this coil. There is 2 leads in and 2 leads out. So, using just one works great!!! This baby works very good!! I'm very pleased with this products!!!

This product does eliminate hum but also significantly reduces quality of the signal. This made my studio monitors sound like a cheap boom box. I had significant reduction in high end details and quality. This product does work to eliminate ground loop hum and it is cheap.. I suppose you get what you pay for. If you want a much better solution for ground loop issues, try an ART DTI...

'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.

If u own a Bosse Amp that I really trash and loud noises in u car radio..this device will quite it Down..So far im very impressed with this gadget

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.
