Ebtech HE-8-XLR overview

  • 1Description

The HE-8XLR Hum Eliminator from Ebtech is an eight channel rack mount unit, designed to eliminate 60 cycle hum caused by ground loops. It is also designed to convert unbalanced lines to true balanced lines, since unbalanced lines are more susceptible to picking up electrical noise and RF interference.

The HE-8XLR Hum Eliminator prevents ground loop antennae from forming and picking up AC hum. AC hum and noise are almost always caused by a loop antenna effect across signal lines between two or more pieces of gear, or by long unbalanced cables picking up noise. Loop antennae are basically a type of radio antenna, which tend to pick up the 60Hz (and harmonics) AC signal being broadcast by a building's electrical current. These loop antennae are closed circuits usually along the ground wires and hence are commonly called ground loops.

Unbalanced signals are more susceptible to picking up electrical noise and RF interference than balanced signals are. The longer the unbalanced cable, the greater the chance of a problem. The
HE-8XLR Hum Eliminator is one of the most cost-effective ways to convert between unbalanced signals and true balanced signals.

Eliminates AC hum/60Hz buzz and noise quickly and easily
Breaks grounds 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
Completely passive design with audiophile quality components assures the best possible noise and distortion performance

    Ebtech HE-8-XLR reviews

    HE-8XLR Hum Eliminator is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Essential Equipment for the Sound Engine The HE-8XLR has a permanent home in the sound booth of our church next to our 56 channel mixer. It's function of breaking ground loops is absolutely essential and the fact that I can patch ground noise affected equipment through it quickly without running to stage saves so much time. How did I ever live without this tool? There is no downside to having the Ebtech Hum Eliminator on hand at all times. It can save your performance!
