XtremPro Hi-end Ground Loop Noise Isolator/Filter for Car Audio/Home High-fidelity System - Black (65042)

I was getting major interference in the stereo system from the alternator. I plugged this into the system per directions, and it killed the interference for that speaker. That's a drawback ... if you have amps, or use all the pre-outs, you're going to need one of these for each set of pre-outs. A bit inconvenient, but worth the investment!

I installed this in a home audio system where I use a 3.5mm jack from a pc to a pre-amp then out to the rest of the system. I was getting some slight hiss/hum whenever I turned on the system and the computer was on. Put this inline between the computer and the pre-amp and the noise is 99.9% gone. Now when the system is completely on but nothing playing its silent like it should be, minus a somewhat noisy cooling fan which I am going to replace. This thing is an excellent product.

I used this to correct a buzzing I had and it initially worked. Unfortunately it stopped working right before a house party; turned on my system 10 minuted before the party and I had very loud buzzing (worse than without it). Since it's a few months old I can't return it.

Got rid of 90% of hum, but seems to have a muffling effect on overall sound.

This moduel is really good for the price, better others that I have tried .it doesn't cut out the bass at all the louder you crank up the volume. Will recommend 👌 to others.

Good solid piece of equipment, eliminated speaker movement from phonograph , now I have a low hum, like a ground issue, I’ll have to fiddle with it more

I have a PC hooked up to my home theater, and for some reason when I played games there was a buzzing noise. I narrowed it down to my subs making the sound. After trying a few things like changing where I plugged everything in, and getting a better power strip, I started searching for answers. Luckily I came across this product, and a review on here that described this exact scenario. Placing this product between my receiver and my sub amp (Crown X3000) has completely removed the problem! I don't know if a cheaper product would have done the same thing, but this one feels very solid, and works.

I bought this to fix the hum in my powered subwoofers and it didn't make a difference. The hum is still there....so it may be something else wrong with my system or ground issue. I am using two klipsch powered 10" subwoofers (one wired and one wireless) and a Denon 5.1 receiver. Subwoofer RCA cables are thicker, not super high end but they are not cheap either..

It fantastic don’t spend hundreds dollars if your turntable has a hum noise give this a try you will be happy don’t spend hundreds dollars for some brand name this is the same but will put money back in your pocket

Interference can be caused in many different ways. I thought that I was having a ground loop problem so I tried this and it totally eliminated my noise. It can be a guess. My next try was going to be a voltage source conditioner which I still might need for my noisy ham radio...

I spent a bit more with this product since I’m not using it in a car stereo application. Although it did reduce the buzz about 40%, it didn’t remove it completely.
