The safest way to eliminate unwanted noise in your live sound setup is with the ART CleanBOX II. Hum in an audio system is often caused by loop effects which act like antennas. Typically, these loops are connected via grounds, more commonly called "ground loops." These loops can easily pick up a 60Hz (or higher harmonics) hum transmitted by electrical wiring.

Here are some common examples of ground loops where the CleanBox II can eliminate the hum:

The power ground of a synthesizer, connected to the signal ground of the synth, into a mixer's ground, then into a mixer's power ground.

The signal ground of a send effect (reverb, delay) into a mixer, and the connecting power grounds of the mixer and the unit.

The power ground of a guitar amplifier, connected to a signal processor which has a second guitar amplifier on the other channel, and then the second guitar amp's power ground.

All such common ground loop problems are solved by the ART CleanBox II.

Easily removes ground loops without any signal degradation.

    Comments about ART CleanBox II Passive Hum Eliminator:

    Just got this as I have dirty power issues at one of the places I play at and get lots of white noise. It took me all of five seconds of use to start repackaging this item for return. It seriously reduced the volume and tone coming out of my amp. I can't imagine how this item would do anything to improve the issues it states on the advertising. White noise was reduced at a level equal to the amount of volume that was reduced. The net-net resulted in me turning the amp back up only to have the original level of white noise return.
