CleanBox II -
ARTcessory
“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. Some examples of Ground Loops:
- 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.
The CleanBox II easily removes ground loops without any
signal degradation.
Features:
- Virtually indestructible, compact steel chassis
- Two independent channels for two correcting two ground
loops, or for processing stereo signals
- 1/4" TRS input and output jacks supporting balanced or
unbalanced connections
- Unity gain. A signal into the CleanBox II will be the
same level at the output
