Ebtech Hum X Hum Exterminator
The Hum X Exterminator removes unwanted voltage and current in the ground line that cause ground loop hum. This noise reduction adapter simultaneously maintains a solid, safe ground. You no longer have to run your audio signal through filtering that results in loss of volume, tone, or both. Some devices simply remove or float the ground, which is never safe! Hum X removes the ground loop while leaving the ground and your signal intact. Easy to use and completely effective!...details

Ebtech HE-2-XLR Hum Eliminator with XLR
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....details

Ebtech LLS-2-XLR Line Level Shifter with XLR
The Line Level Shifter is designed to increase or decrease signal voltage (-10dBV and +4dBu) without adding noise. It also converts back and forth between balanced (+4dBu) and unbalanced (-10dBV) signals automatically. The Line Level Shifter contains Ebtech's Hum Eliminator technology to break ground loops that cause AC hum.The two-channel Ebtech Line Level Shifter is equipped with 1/4" ins/outs AND XLR ins/outs. It allows you to increase or decrease audio signal levels between —10dBV and +4dBu while preventing hum cause by ground loops. Passive design means no power is required. Two-year warranty....details

Ebtech 2-Channel Hum Eliminator
The Ebtech 2-Channel Hum Eliminator is a quick-and-easy way to eliminate AC hum and noise. Insert the Hum Eliminator in the line-level signal path after your preamp and it will break noisy ground loops without degrading your signal. Use it on long unbalanced lines that are especially vulnerable to noise. Many mixers don't have balanced monitor outs and aux sends, but you can make them quiet using Ebtech's Hum Eliminator. Includes 1/4" TRS smart jacks that convert automatically back and forth between balanced and unbalanced lines. Made in the USA....details

Ebtech 8-Channel Hum Eliminator
This 8-Channel Hum Eliminator from Ebtech breaks ground-loops safely while leaving all signal grounds intact. Automatically translates signal voltages to match differences in ground potentials, avoiding clipping. Converts between balanced & unbalanced lines. 1/4" TRS inputs and outputs....details

Ebtech 2-Channel Line Level Shifter
The Line Level Shifter from Ebtech uses the physics of inductance and impedance matching to increase or decrease signal voltages without adding noise or employing active electronics. Allows a step up in volume approximately 11 decibels without adding system noise. It also converts back and forth between balanced and unbalanced signals automatically. And as a bonus, it contains Ebtech's Hum Eliminator technology to break ground loops....details

Ebtech Swizz Army Cable Tester
The Ebtech Swizz Army Cable Tester is the professional's choice in multifunction cable testers. It displays the exact wiring of any cable or adapter—even allows testing of installed cables inside walls. Another cool feature is its patented intermittent detection, which lets you wiggle cables and discover any intermittent problems, the kind that usually go undetected. The Swizz Army Cable Tester also functions as a tone generator, phantom-power detect, and grounded XLR shield detect....details
