    555-16050 - 2 Channel Ground Loop Isolator Hum/Noise Eliminator 1/4"

    2 Channel Ground Loop Isolator Almost all 60Hz AC hum is caused by ground loops that act like radio antennae (loop antenna). The Hum Eliminator completely eliminates this by breaking the ground loop, making it impossible for the signal lines to pick up the AC hum and noise in the first place.
