Rated 5 out of 5 by from Fixed a few noise problems all at onceI bought this originally to get rid of a small amount of hum that a subwoofer made. It didn't reduce the hum at all, so I was kind of disappointed. It sat for a few days & then I tried it on my PC. My PC has always had high frequency sounds come threw the speakers from my Wi-Fi router & my Razer - Death Adder 3500 dpi Gaming Mouse. I couldn't believe that this product removed all the awful audio noise & it didn't reduce the audio quality one single bit. I have tried a few different cables & they didn't help get rid of problem. I have had this problem for years & I finally killed the noise with this product.

Rated 1 out of 5 by from Can you hear me now? Yep, its still humming!I bought this product to get rid of the hum produced threw my powered subwoofer. It has a Dayton Audio - SPA250 plate amp on it & these amps are known for producing subwoofer hum from what I have read in the reviews. Ok, no problem I'll just buy a Ground Loop Isolator & problem solved. Thats what I thought atleast. It didn't reduce the hum one bit. I don't know if the unit is faulty or what. I guess I should have boughten the BOSS - B25N Ground Loop Isolator & Noise Filter (part # 265-4041) instead. Now I am out of $10.00 & still have the problem & I have to try the BOSS model to see if that one can fix the problem. First product from Parts Express I boughten that didn't work as advised.

Rated 5 out of 5 by from Exactly what I hoped forBought this to get rid of the hum in my subwoofer that only happened when I had our Comcast cable lead connected to the cable box. I've had this annoying hum for more than 7 years, and now it's fixed! So Happy! Comcast came out a few years ago trying to fix it for more than an hour (to their credit) so I had given up and thought it was a problem with my AV receiver.

Rated 1 out of 5 by from So much for audio quality....Advertised as "eliminates the noise in the audio line without sacrificing the audio quality". Bought this with some nice "Wired Home" RCA cables to replace some lousy cables I had between my PC audio output and stereo system. The new cables alone got rid of any AC hum I previously had due to better shielding. I tried the isolator just for kicks. The highs seemed quite subdued. Removed it and it was like night and day. This is a good choice for A) Really bright sounding, improperly installed car audio with too many tweeters or B) If you are deaf. Find another way to get rid of the noise.

Rated 5 out of 5 by from Works greatI bought this to get rid of some feedback I was getting from running rcas from a sound card on my desktop to my Yamaha receiver to play media from that same desktop onto my Samsung tv. Worked flawlessly I have no feedback what do ever just a clean audio signal.

Rated 5 out of 5 by from Great product to end Hummmmm...Ive purchased these on multiple occasions, and keep them in my service vehicle at all times. As an Audio video systems integrator, Ive been in the business 30 years and ground hum can ruin a great installation. This device solves the problem consistently, zero effort, and no degradation of sound quality. Its the 10 second fix for ground loops between audio video systems and audio distribution amplifiers.

Ground Loop Isolator

Hi there, what are the dimensions of the main casing?

Asked by: Rhys E
The body of this measures 2-5/8"L x 1-3/8"W (diameter).

I use it for a subwoofer which needs only one RCA plug. Can I use only just one side of it? What if I use a "Y" adaptor at either ends, will I double the benefit?  

Asked by: Akla
You do not need to use a Y cable, simply use one side or the other.
