The Hum X filters out unwanted voltage and current in the ground line that cause ground loop hum while simultaneously maintaining a solid, safe ground. You no longer have to run your audio signal through any type of tone-sucking filter. Simply place the Hum X on the end of the power cord of the equipment that has a Ground Loop and plug the Hum X into the wall outlet. Ground Loop is gone -- safely -- and audio signal remains intact. The easiest, safest way to get rid of ground loop hum.
Connect the Hum X between the offending equipment and your AC source and it safely filters out voltage and current that cause ground loop hum. The noise is gone but the gear stays safely grounded.
