2 Packs Ground Loop Noise Isolator for Car Audio/Home Stereo System

I don't write reviews, but this was too good to be true. I bought the Noise Isolator for my Polaris SXS. I just installed an amplified speaker inside, and it was blasting with a screeching noise that wouldn't stop. If I blasted the music all the way up, it would barely hide the noise. I did some research on the problem, and it led me to the isolator. I ordered it on Sunday night, and Amazon said two days for delivery. Well, it came in early! When I installed it, I thought there was a problem. The noise was instantly gone. No screech or squeak. What a difference. Great product!!

I was pleasantly surprised when I used this item. Great price! It did Exactly what it said it would do. I have a ground loop issue at one particular venue, and this item totally removed the hum while preserving original signal quality. I subsequently bought 4 more. 1 for each set-up. 2 thumbs up!

Plugged both sides into my pc connected to the TV. Before the speakers had an annoying underlying buzz. After it was silent and only the audio I want comes through!

There is worst noise now when the system is off. Tested it and there are various issues with budget isolators

I’ve used many ground loop isolators and these are the only ones that fully minimize ground loop noise. For some reason many of the other ones I've used introduce their own noise or do not remove all of it. However, I do have two complaints/tips where the product could be improved. 1. The body of the isolator is made out of plastic, so when it’s in a heavy electrical noise environment, I.e. surrounded by other networking cables or what not, noise will be introduced. Some kind of shielding around the isolator would go a long way. 2. The tolerances of the audio jack plug ins are not great sometimes. Some cables are looser than what I’m comfortable with when plugging them into the isolator.

I have 2 laptops, a phone, and a tablet all connected to a little mixer that is connected to an amplified speaker on my desk when I'm working. The crosstalk from these devices is awful (laptops are notorious for this). I got four of these and connected three to three of the inputs and one to the output of the mixer (the tablet therefore being isolated from the rest as a result). The crosstalk is gone. The only noise is from the amplified speaker-which is the speaker's fault-so adjusting levels cut that out. Problem solved! These are bi-directional, so which end you connect to in/out doesn't matter. They come with a short patch cable, which in most cases you'll need. I chose to connect them close to the mixer for my situation. No power is needed as these are passive filters. I don't have a professional audio setup, so I can't pick out any issues with the quality; it sounds good to me!

Instantly fixed a huge problem for me! In my home studio, I was getting hum from the microphone going into the input on my computer. ChatGPT and I did some troubleshooting and found it to likely be ground loop hum. It was annoying and kept me from enjoying my new microphone that I had just recently purchased. These arrived today. I immediately plugged one in into the line-in on my computer (and the other on the output) ... and the hum is GONE. 100% completely gone. EXACTLY what I needed. Fixed ... on the cheap! :)

I received two. One works great and eliminated the audio crackling I had. The other also got rid of the crackling but the left audio channel didn't work through it.

Compre 2 para calarlos y si funciono muy bien, en una consola de audio tenemos conectadas 3 computadoras y las cuales ocacionaban ruidos o zumbidos, utilizando este equipo en 2 computadoras esos ruidos desaparecieron a lo cual mandé pedir otro mas para completar el equipo que me falta

These worked really well stopped the knocking noise coming for my aux port on my car I recommend them if you have the same issue

Muy buen producto

All the mouse noise from the speakers on my desktop pc is gone. No more noisy scrolling, works great.

Funcióna bien ayuda a eliminar ruido eléctrico
