A neat little device that lifts the ground on two channels by using transformers, thus eliminating earth loops. Well made and good value. I used it between two guitar amp DI's and inputs to the PA mixer.

It does what it's supposed to. It isolates the ground interference in sound between two powered devices. It IS however very expensive for what it is. I bought mine based on a recommendation for a livestream sound setup (me not knowing anything about sound setup prior to this), but if I had known just what this did (I.e. a simple ground loop isolator) I would have gotten a cheaper alternative. You can find extremely cheap unlabeled ground loop isolators for a fraction of the cost. I now have one of these and 6 of some cheap Chinese no-brand isolator. They do the exact same job and both "brands" do it well. This one just has the Behringer logo, has a metal casing, and is square so it stacks better while the other "knockoff" GLI were cylinder shaped, and wrapped in shrinktube plastic.

Was plagued with horrible AC sound from my computer to my active studio monitors, I even switched outlets that were definitely grounded, no dice. Tried loads of different solutions until I found a youtube video about the issue where he recommended this product. Just connected it and the sound is completely pure with no noise whatsoever, couldn't have been happier with the results! If you have a ground loop and can't fix it, this is a really reliable and easy fix, just make sure you have enough cables.

As a pro sound engineer I find these little boxes a useful “get out of jail” device when working for the first time or casually with bands/artists whose own equipment has or creates an earth loop hum. Not a cure-all but often a quick fix for the price of a metal box an 4 jack sockets!

this is a amazing product. It has removed all the hums i had. only problem is that both the channels are links so you cant use them for different things. apart from that it is an amazing product that i would highly recomend.
