Audio Inputs
Mbox Pro provides six channels of analog inputs,
and supports microphones, guitars, keyboards, and
other types of instruments and devices.
For information about connecting specific audio
sources, see “Connecting a Microphone” on
page 16, and “Connecting Instruments to the
Mbox Pro” on page 18.
Mic/DI Inputs 1–2/Line Inputs 1–2
The front-panel Mic/DI inputs 1–2 provide combi-
nation XLR (Mic) or a 1/4-inch (DI) jacks for In-
put channels 1 and 2.
Toggle each channel’s Front/Rear input source
switch to switch between the front-panel Mic/DI
input and the 1/4-inch TRS Line Input located on
the back panel.
When the switch is in the “out” position, the front
panel Mic/DI input is active; when “in” the rear
Line Input is active.
Mic Inputs 3–4/Line Inputs 3–4
The back-panel Mic inputs 3–4 provide two dedi-
cated XLR connectors for Input channels 3 and 4.
Toggle each channel’s Front/Rear input source
switch to switch between the XLR input and 1/4-
inch TRS Line Input located on the back panel.
When the switch is in the “out” position, the Mic
input is active; when “in” the Line Input is active
for that channel.
Aux Inputs 5–6
The Aux inputs 5–6 section provide dual-mono
RCA jacks or a single 1/8-inch stereo jack for Aux
input channels 5 and 6.
If the 1/8-inch jack and the RCA jacks are both
connected, the 1/8-inch jack takes precedence over
the RCA jacks.
Use these inputs to connect line-level sources such
as mixers, CD or DVD players, or MP3 players.
