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

Worked a treat to kill an annoying noise, definitely worth the money

I recently managed to secure a Roland MC-505 Groovebox but I had a really annoying low frequency hum coming out of my amplifier through the 505. I connected up the ground loop & it totally eliminated the hum from my Groovebox. I highly recommend this product if you are using old school synthesisers through an amp like I am. Brilliant but simple solution.

Does absolutely the opposite of what it should do

It work in my car very well

then this product works like a charm, however will reduce your bass, had to increase the subwoofer gain which for me was not a problem

It's really helped with reducing interference in a Campervans audio system but the sound quality was compromised. There was a decrease in the higher frequency levels, the sound isn't as clear as it used to be.

If you have an annoying buzz in your headphones, or speakers, this could be caused by a bad earth connection. My property has the worst grounding that I ever encountered, and these removed the hum encountered between my audio equipment, and with my pc. Hum all gone, with no loss of signal quality. Job done. :)

All good
