Mbox Hardware Overview
Mbox Front Panel Features
Figure 1 identifies controls, indicators, and input and output ports on the front panel on the Mbox.
The Mbox front panel provides the following:
Signal/Clip LEDs
These LEDs illuminate green in the presence of
audio signal, and illuminate red if the signal
reaching Mbox has clipped.
Gain Controls/-20dB Pad
These knobs adjust the input gain levels of the
Mic/Line inputs. Turn the knob clockwise to in-
crease gain, and counter-clockwise to decrease
gain.
If your input signal is too hot even with the
Gain knob at a low setting, pull the Gain knob
out to engage a “pad” that attenuates the signal
by 20dB.
Instrument Inputs
These 1/4-inch TS inputs are for connecting an
electric guitar, bass, or other instrument-level
signal. The level for these inputs is controlled by
the Gain Controls.
