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.
