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

Key features:

• Suitable for removing hum/ground loops such as:
  • 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
  • Signal ground of a send effect (reverb, delay) into a mixer & the connecting power grounds of the mixer & the unit
  • Power ground of a guitar amplifier, connected to a signal processor which has a second guitar amplifier on the other channel & then the second guitar amp's power ground
• CleanBOX II easily removes ground loops without any signal degradation
