LIFTER Pin 1 XLR Ground Lifter

Works great, used it with a keyboard DI that had a faulty ground lift, worked like a charm!

... it didn't help with my problem: Fractal FM3 into Xitone powered wedge. What did help a little is a high EMF filtering power strip, but there is still hum (buzz). Not sure what's wrong, but there is no noise with no XLR is plugged into the powered speaker. I'll have to try a TRS cable, to see if that creates a buzz. Oh well. It was worth a shot.

There's 2 noises coming from my Fender GTX XLR output... hiss, and a slight hum - 60hz I assume. This got rid of the hum. Loses 1 star because of stability - if you wiggle it, it works / doesn't work.

I actually was a bit skeptical about this for the price point compared to other over $80 and I actually gave it a try and boy was I glad I did they actually cleaned the ground noises I was getting

Exactly what it is described. Well built. Just what I needed.

If you are a DJ and have hum. This will help to get stop it. This is something any one with pro sound needs to have.

Necessary if you want to keep phantom power. Am still experiencing some ground loop buzz, however (at low level, fortunately) from an altar mic connected to a Mackie mixer, which in turn is feeding another mixer through Whirlwinds Isolator (which is a great isolator, but doesn't pass phantom power).

This ground lift works, but not quite as well as using a pair of DI's back to back. Still, much cheaper.
