Rollover to Zoom 



Exterminate hum at the source. The Hum X filters out unwanted low voltage from the ground line that causes hum and buzz. Simply place the Hum X on the end of the power cord of the equipment that has (or is creating) ground loop hum, plug the Hum X into the wall outlet. Ground Loop is gone and audio signal remains intact. Easy to use, easy to install and completely effective!

Ground Hum is the enemy of installers, contractors, sound engineers and musicians alike. Ground Loop Hum can be very hard to get rid of since it does not follow any set rules. Ground lift adapters (which are one common way around Ground Hum) are not safe, but the Hum X is the safe and simple way to get rid of the hum and the buzz
Ground Loop
Eliminate ground related hum/buzz right at the source, simply place the Hum X on the end of the power plug and plug the Hum X into wall outlet. This filters unwanted currents and voltages in the Ground line while maintaining safe ground. This is not a ground lift and we do not recommend a ground lift to get rid of the buzz since they aren't safe. The Hum X is completely safe and you can use it as long as you want, so enjoy your hum-free equipment.

The Hum X is suitable for 120 Volt North American Type A or B outlets only. The maximum recommended current draw per Hum X is 6 amps.


The Hum X is available in hang-able, resealable clear clamshell packaging or a contactor box. It is encased in a durable thermoplastic outer shell which is strong enough to endure chemicals and environmental stress cracking. Since your equipment will be silent you won't be sure if it's working, that is why the Hum X comes with a handy LED light that lights up when it is plugged in and shows that the unit is working.

  • Use only on equipment with current draw of 6 amps (720 watts) or less
  • Not a ground lift - maintains equipment ground
  • Suitable for use on 120V 60Hz grounded USA-style power outlets
  • Use 1 Hum X per piece of gear. Multiple hum issues may require more than one Hum X. Not designed to get rid of cable related or guitar pickup related hum.
  • NOTE: Check Instructional Video and User Manual before use
