Mbox Pro Setup Guide18
Using a Mic with an XLR Connector
(Input Channels 3–4)
To use a microphone with an XLR connector:
1 Plug your microphone cable into one of the
two Mic inputs (XLR) on the back of Mbox Pro
(In this example, Input 3).
2 There are two Mic inputs (XLR) on the back
panel, (Input 3 and 4). On the front panel, set
the Mic/Line input switch for channel 3 to the
“out” position (microphone).
3 If your microphone requires phantom power,
make sure the microphone is connected, then
press the Phantom Power switch (labeled 48V)
on the front of the Mbox Pro. This switch sends
48V to all four inputs. The 48V LED on the front
of the Mbox Pro will light when phantom
power is being supplied.
4 On the front of the Mbox Pro, turn the master
volume knob to the desired level.
5 On the front of the Mbox Pro, carefully turn
the Gain knob to the right to increase the input
level of your microphone signal.
6 If the incoming signal is too loud, press the
Push/Pull knob to the “out” position to engage
the –20 dB pad.

Use the corresponding back panel inputs
(marked Line Input 3 and Line Input 4) on
the back when working with line-level sig-
nals. In that case, set the Mic/Line input
switch for channel 3 to the “in” position
(line).
