Whirlwind's LIFTER is ideal for troublesome 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.

The ground lifters have been installed for several weeks now and the speaker buzz has not returned! The speakers at church are daisy-chained, but on different electrical systems and so they're grounded in different places. This was allowing a ground loop to cause a loud buzzing that would come and go randomly. I powered the speakers down while they were buzzing, installed the lifters, no more buzz!
