Mbox Pro Front Panel Features
Figure 1 identifies controls, indicators, and input and output ports on the front panel on the Mbox Pro.
Input Combo Jacks (Mic/DI)
These combination jacks (Mic/DI) provide XLR
and 1/4-inch (TS) inputs for Input channels 1
and 2.
Gain/–20 dB Pad Switches
These knobs adjust the input gain levels of Mic/DI
1 and 2, or Mic 3 and 4. Turn the knob clockwise to
increase 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 en-
gage a “pad” that attenuates the signal by –20dB.
Front/Rear Input Source
Switches
These buttons select the input source for input
channels 1 and 2. When “out”, the front panel
Mic/DI input is active; when “in” the back panel
Line Input is active for that channel.
