Hosa 2-Channel Hum Eliminator 

The HEM-331 Hum Eliminator is designed to get rid of "ground loop" problems, such as AC hum or buzz and/or pop noise in any audio system. Use it to convert between balanced and un-balanced lines.  Features include: pure audio transmission; ¼" Tip-Ring-Sleeve (TRS) phone jacks for inputs and outputs; ground lift switch; no external power needs; rugged steel enclosure.  This is a great way to send the HI-Z main outputs from a electronic drum machine over long distance to the board.
