I have 2 scanner radios and a ICOM receiver that I run through a 4-port switch to my PC speakers.Couldn't figure out how to eliminate the hum without cranking up the volume to override it but this ground loop isolator was exactly what I needed and took care of the problem - I highly recommend it!
I use this in my car for audio in from my phone.
No matter what I do I can't get my aux audio to play while this is plugged in.
!The audio was isolated to just one side and made my music sound like it was underwater...which would be pretty cool if I was a mermaid, but I'm just a person trying to make it to work without wanting to rip out my radio.
Does not work.
It's horrible doesn't work it's supposed to isolate noise but it creates noise will never buy this product again And I tried to return it and you can't.
But no change in noise.
