Mbox Pro.
Figure 1. Mbox Pro front panel
Chapter 2: Mbox Pro Hardware Overview 5
Input Combo Jacks (Mic/DI)
LED Ladders (Inputs 1–4)
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 engage 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.
Soft Limit Switch
These switches engage a soft limiter on that
channel, applying a smooth, overdriven tapetype limiter to strong input signals.
These four, eight-segment LED ladder-style meters illuminate green in the presence of audio
signal, and illuminate red when the signal is
about to clip (overload) the input. The LEDs are
associated with signals routed from inputs 1–4.
48V Switch and LED (Phantom
Power)
The 48V switch toggles phantom power on/off
for all mic input channels. The LED, when lit,
indicates that 48V phantom power is active on
the XLR Mic inputs.
About Phantom Power
Most condenser microphones (such as an
M-Audio Solaris) require phantom power to operate. Dynamic microphones (such as a Shure
SM57) do not require phantom power to operate, but are not harmed by it.
Although phantom power can be used
safely with most microphones, it is possible
to damage some ribbon microphones with
it. Always turn off phantom power and wait
at least ten seconds before connecting or disconnecting a ribbon microphone.
Mic/Line Input Source Button
These buttons select the input source for input
channels 3 and 4. When “out”, the back panel
Mic input is active; when “in” the back panel
Line Input is active for that channel.
Mbox Pro User Guide6
When using phantom power, Mbox Pro’s
maximum current per microphone is 10 mA.
If you are not sure about the phantom power requirements for your microphone, consult your
microphone’s documentation or contact the
manufacturer.
Master Volume Knob
The Master Volume knob adjusts the output
level of the assigned Monitor output pair. The
Master Volume knob is assigned to an output
pair (1–2, 3–4, or 5–6) in the Control Panel. See
“Master Vol.” on page 32.
When pressed and held, it sources Aux inputs
5–6, letting you can switch between monitoring
playback from your audio application and monitoring an external source (such a CD player)
connected to Aux inputs 5–6.
Headphone Outputs
Dim/Mute Switch
The Dim/Mute switch affects the output volume
for control room outputs as assigned in the
Driver Control Panel setup (by default, Line outputs 1 and 2.) See “Control Room Assignment”
on page 32.
The switch has two functions:
When pushed, Line outputs 1 and 2 (or the
currently assigned Control Room outputs) are
dimmed. When Dim is engaged, the switch LED
lights solid.
When pushed and held in, Line outputs 1 and
2 (or the currently assigned Control Room outputs) are muted. When Mute is engaged, the
switch LED flashes.
Mono Switch
The Mono Button sums the control room outputs to a mono signal (delivering that identical
signal to both speakers) via the Driver Control
Panel or the Mbox Pro. When engaged, the
Mono LED lights.
Spkr (Speaker) Button
You can assign Monitor outputs pairs to the
Speaker button and cycle through the pairs as
configured in the Control Panel (see Chapter 5,
“Using the Driver Control Panel” and “Control
Room Assignment” on page 32). This is useful
for A/B-ing your mix between different studio
monitors.
Use the A and B, front panel Headphone outputs
to connect stereo headphones with a 1/4-inch
stereo connector. Headphone output A mirrors
Monitor outputs 1–2 by default. Sources for the
Headphone outputs can be configured in the
Control Panel. See “Stereo Mix Section” on
page 34.
Headphone A and B Volume Knobs
The Headphone knobs adjust the output level of
their corresponding Headphone output (A or B).
Multi Button
The Multi button can be assigned to execute several functions in Pro Tools, including
Track Create, Start/stop Record, Tap Tempo,
Toggle Marker Locations, and Save Session. For
detailed information, see Chapter 6, “Using the
Multi Button.”
Power Indicator LED
The Power LED indicates that the Mbox Pro is
receiving power from its power supply. Once the
light is on, audio can pass in or out of the system. If the light is flashing, the power is not correct or clock is not locked.

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 “insert”) an external analog effect such as a compressor 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.
Mbox Pro User Guide8
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 using 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”).
+4/–10 Switches
Power Switch
These switches let you select +4 or –10 input operating levels for Line Input channels 1–2
and/or 3–4. When “out” the level is set to +4 and
when “in” it is set to –10.
If the device you are connecting to any of
these inputs has unbalanced outputs (or
you are using an unbalanced TS cable), set
the line input switch to -10. For balanced
outputs (using balanced TRS cables), set the
switch to +4. Refer to your device’s documentation.
Aux Inputs 5–6
The RCA jacks and the 1/8-inch mini are all part
of Aux input 5/6.
Use the RCA jacks for line-level devices like
CD players or mixers.
Use the 1/8-inch mini to connect line-level
sources such as MP3 players with an 1/8-inch
stereo connector.
FireWire Ports
These standard FireWire 1394 connectors are
used to connect your computer to Mbox Pro.
The Mbox Pro cannot be powered solely
through its 1394 connection to your computer.
The Mbox Pro requires the power supply to
function.
Power Input Jack
This port supplies power to Mbox Pro using the
included power supply. The Mbox Pro requires
the power supply to function. For stand-alone
mode you power on the unit with a power connection and no FireWire connection.
This button is used to turn Mbox Pro on or off.
Word Clock, MIDI, S/PDIF
Connector
The DB15 connection that handles Word Clock,
MIDI, and S/PDIF is a multi-pin port where you
plug in a breakout cable (included). On the opposite end of the cable you can connect to Word
Clock, MIDI, and S/PDIF devices.
Breakout cable
Foot Switch Connector
The footswitch connector on Mbox Pro lets you
use a footswitch to control either playback
start/stop or recording punch in/out. Both
QuickPunch audio punch-in and punch-out
and MIDI punch-in and punch-out recording
are supported.
The footswitch connector is designed specifically for instantaneous (momentary) on/off
pedals with a 1/4-inch TS connector. Continuous on/continuous off pedals can also be used,
but may result in unexpected behavior.

Making Studio Connections
This chapter provides step-by-step instructions
for connecting mics, instruments, mixers, headphones, speakers, and other devices to
Mbox Pro.
Connecting Outputs
To hear audio from Mbox Pro, you will need to
connect headphones or an external sound system (such as powered monitors or a home stereo) to Mbox Pro.
Connecting Headphones
You can use headphones equipped with a 1/4inch stereo jack to monitor your audio.
To connect headphones:
1 Connect headphones with a 1/4-inch stereo
connector (or adapter) to the Headphone outputs A or B.
2 Adjust the volume using the corresponding
Headphone Volume knob on the front panel.
By default, Headphone output A mirrors Monitor output channels 1–2.
You can create independent stereo mixes for
each headphone output in the Driver Control
Panel. See “Stereo Mix Section” on page 34.
Do not use the front panel headphone outputs for anything but headphones. If you
use a headphone distribution amp or cue
system, use any of the six Monitor outputs
on the back panel. See “Monitor Outputs
1–6” on page 14.
Headphone jacks and controls on front of Mbox Pro
Chapter 4: Making Studio Connections 13
Connecting a Sound System
Monitor outputs 1–6
The default monitor outputs on the back of the
Mbox Pro (Monitor outputs 1 and 2) support
1/4-inch plugs. These connections can be balanced TRS (Tip-Ring-Sleeve) connectors, or unbalanced TS (Tip-Sleeve) connectors such as
those on instrument cables. To listen to your to
audio, connect these outputs to any amplification system: powered speakers, a home stereo
system, or an audio mixer.
To connect to a stereo system:
When connecting to a stereo system, connect
the left channel of the stereo (often the white
plug) to Monitor output 1, and the right channel of the stereo (often the red plug) to
Monitor output 2.
Home stereo systems often use RCA connectors. You can use an adaptor or a special cable to convert from the 1/4-inch TRS (TipRing-Sleeve) connectors used by Mbox Pro to
the RCA connectors on your home stereo.
Monitor Outputs 1–6
Monitor outputs 1–6 can be connected to any
device that has analog inputs. Use these six balanced 1/4-inch TRS outputs to feed analog devices such as headphone amps or cue systems
for discrete headphone mixes, samplers, or a secondary recorder.
Line Out connectors for monitors on Mbox Pro
To connect to a sound system:
For stereo monitoring, connect Monitor out-
puts 1 and 2 to the inputs of your main left and
right speakers. You can hook up more than one
set of stereo speakers and switch between them
(Speaker A, B, C switching). See “Output Setup”
on page 31.
Mbox Pro is capable of 5.1 surround monitoring complete with custom configuration
and routing controls. For more information,
see “Output Setup” on page 31.
Mbox Pro Setup Guide14
There are other use for Monitor outputs, such as:
• Stereo main monitors (Monitor outputs 1–2)
• Stereo/Alt monitors (Monitor outputs 3–4)
• Surround (Monitor outputs 1–6),
To connect additional Mbox Pro outputs:
Using 1/4-inch TRS cables, connect any of the
Line Out (1–6) connectors on the back panel to
the inputs of your external devices.
