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

I usually don't do a review 10 mins after I use something but this was out standing. Installed a new amp, speakers, and LOC on ly 2021 Spyder RT Limited. 3 days! After I got it up and running it had a loud hiss. So from my military days I remembered we had filters we could install so I asked chatgpt and this is what they recommended and boom! No more hiss!!! Installed between the LOC (red box) and the AMP.

Solved the annoying hum I had in my DAC > Sub > Speaker chain. Installation was simple, though placement mattered: it worked between the DAC and Sub, but not between the Sub and speakers. Build and cable quality are adequate for the cost. Most importantly, the hum is gone with no noticeable loss in audio fidelity.

Reduce noise not static turn volume up because sound droped static was still present.

Eliminated my alternator whine, didn't really affect sound qualify. Even if it did, certainly much better than hearing that noise.Just give it a shot to see if it works for you!

I have a very long run of RCA cord from my media server to my main receiver, and was getting serious buzz on the living room speakers. Figured it was probably a ground loop, and sure enough this fixed the problem immediately. There is a small reduction in bass, in that room, but not enough to be a problem for casual listening. If it ever really gets to me, well that's what subwoofers are for.

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...

So i bought this bc my old isolator started to give up on me after 10+ years so i needed a replacement. Now THIS or any other isolator alone 9/10 will NOT completely get rid of your audio feedback. YOU HAVE TO GROUND THE RCA CABLES BEHIND YOUR HEAD UNIT!!!! Take some speaker wire and tightly wrap it around the rca plugs behind your head unit and then take the other end and tightly wrap it around a screw on the side of your head unit and then add this isolator to your amplifier and you will completely eliminate any noise feedback.Noise feedback comes from buying cheap/mid parts. It is what it is but doing this trick will eliminate that feedback for you. Other then that i was def satisfied with the build quality of this isolator. Im gonna buy another one for my front speakers even though i dont currently need it.

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.
