No buzz, no hum, no signal loss, no filtering, no noise gates.

The Ebtech 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 a true balanced lines.

Do you hear a hum or buzz in your audio signal? Are long unbalanced lines across stage creating noise problems? Cancel unwanted noise with the Hum Eliminator™ from Ebtech®.

Almost all AC hum (60Hz in the US, 50 Hz 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 suppresses 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.

Truly a great piece of gear. No muss, no fuss and about as straight forward as it gets. Easy to use and I love the option of XLR or TRS 1/4. We've been using this for the mains at our church (an all metal building) and it completely KILLED the hum..."total freakin' silence". We've been using for about 6 months with no issue. Just today I purchased a second unit for the run to our monitors.
