Mbox Pro Back Panel Features
Figure 2 identifies each port on the back panel of the Mbox Pro.
Mic Inputs
These two jacks provide XLR inputs for Input
channels 3 and 4. The Mic signal is adjusted by
the each channel’s Gain knob on the front
panel.
Insert Jacks
Use these 1/4-inch TRS jacks to patch (or “in-
sert”) an external analog effect such as a com-
pressor or limiter onto the input signal, between
the preamp and the A/D converter. Any inserted
effects affect the recorded signal.
These inserts are only active when a connector is
inserted, and are otherwise bypassed. The TRS
jack is configured as follows: Tip=Send;
Ring=Return; Sleeve=Ground.
Monitor Outputs
There are six balanced 1/4-inch TRS analog
outputs that support line level outputs,
multiple stereo monitors, or up to 5.1 surround
monitoring. For more information on
configuring stereo and surround monitoring in
the Driver Control Panel, see “Output Setup”
on page 31.
Line Inputs
There are four TRS balanced analog Line inputs
on the back panel for Input channels 1–4. For
input channels 1–2, Line inputs are selected us-
ing the 01 and 02 Front/Rear switch on the front
panel (set to “Rear”). For inputs 3–4, Line inputs
are selected using the 03 and 04 Mic/Line
switches on the front panel (set to “Line”). Mic
inputs are selected using the 03 and 04 Mic/Line
(set to “Mic”).
