Ideal for troubleshooting ground problems, this female-to-male XLR 3-pin inline device disconnects pin 1 between the connectors. It isolates the ground of a balanced audio signal without requiring you to cut the cable's shield wire.
I am a freelance bassplayer who regularly has been required to use the direct inject line from my amplifier for recording purposes, however the brand that I use lacks an earth-lift button - this handy little device solves that problem for me. Always have it in my kit now.
