Ebtech by Morley HE2 XLR - NOISE SUPPRESSOR 2 XLR CHANNELS

(This text is machine translated) The Ebtech HEXLR Hum Eliminator is designed to eliminate hum caused by ground loops (60Hz AC signal). It is also designed to convert unbalanced lines into true balanced lines (and vice versa). This is because unbalanced lines are more susceptible to electrical noise and RF interference.
