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

Why did you pick this product vs others?:Good

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!

This ground loop eliminator actually made the issue worse. I am not certain if I have a defective product, or I have not properly identified the source of my ground loop. Changing RCA cables did more to control the ground loop than this piece of equipment did. Unfortunately, I still have not been able to entirely get rid of the ground loop buzz. I am using it on a home stereo, not in an automobile.

These actually worked for me to eliminate some noise from my home theater. Only thing is that I could only plug in one device into each of them, otherwise it wouldn't work - hence the four stars.

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 had a problem where my sub-woofer would make a loud annoying buzz whenever I played video games on my gaming PC. My sub-woofer was connected to my receiver through an LFE sub-woofer cable, PC was connected to the TV through HDMI 2.0 and my TV was connected to my receiver through HDMI (ARC). I tried everything to fix it, like plugging in the sub-woofer, PC and receiver into different (and the same) outlets, trying different sub-woofer cables, etc. Nothing seemed to work. Ordered this puppy and Bamm! Problem solved! Complete silence on my sub-woofer! I never write reviews but I had to on this one because I was so frustrated by my problem this product solved it right away. Make sure to order another sub-woofer cable when you order this product because you will need 2 in order to be able to connect from sub-woofer to ground isolator to receiver. Great product!

I had a low buzz/crackling sound with low level sound in my audio on my ceiling speakers in my home theater. I went months researching and rewiring and even added a separate pure earth ground wire from outside in the yard connected to the ground rod,up into the attic and into the outlet my audio video system is connected too. Also bout a power conditioner/surge protector. I also connected the chassis from my a/v receiver to the amp for my ceiling speakers and it only calmed it down a little. Then tried this finally as a last resort and it fixed everything! I’m so relieved! I connected this between my a/v receiver and amp that powers my ceiling speakers. And my sound is more fuller too!

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..
