Ebtech HE2XLR
Hum Eliminator, 2 Channel with XLR Jacks


The Hum Eliminator is designed to eliminate 60 cycle hum (60Hz AC signal) caused by ground loops. It is also designed to convert unbalanced lines to true balanced lines (and vice versa). Why? Unbalanced lines are more susceptable to picking up electrical noise and RF interference.

Almost all AC hum (60Hz in the US, 50Hz in most other countries) is caused by ground loops. These ground loops act like radio antennae picking up hum and noise. 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.

Just plug the Hum Eliminator in the signal lines between the offending pieces of equipment and you're done. Quick and easy. No buzz, no hum. No signal degradation. No filtering. No noise gates. No dangerous ground lifts.


  • Eliminates AC hum/60Hz buzz and noise, quickly and easyily
  • Breaks ground loops safely, while leaving all signal grounds intact
  • Automatically translates signal voltages to match differences in ground potentials, avoiding clipping
  • Converts automatically back and forth between balanced and unbalanced lines at either end
  • XLR inputs and outputs
