Mbox Pro Setup Guide46
5 On the rear panel of the Mbox Pro, use the In-
put Level switch for +4/-10 input line level set-
tings (one for each stereo pair, 1/2 & 3/4). In the
“out” position the level is set to +4; and when
pushed to the “in” position, it is set to (-10).
To use Aux Input 5/6 Line inputs:
1 Plug your keyboard, mixer or other line level
device into the Aux Input 5/6 inputs (L and R).
Connecting DJ Equipment
To use the Aux Inputs 5/6:
1 Plug your DJ mixer, DVD player, or similar
outputs into the Aux Input 5/6 inputs (L and R).
Digital Input and Output
Mbox Pro provides two channels of S/PDIF digi-
tal input and output on the back panel (via a
breakout cable that you connect to the multi-
pin port). This lets you record signals from digi-
tal devices into Pro Tools, and send digital audio
from Pro Tools to other digital devices.
Connecting Digital Devices
To connect Mbox Pro to an external digital device:
1 Using the included breakout cable, connect it
to the Word Clock, MIDI, and S/PDIF input on
the back panel of the Mbox Pro.
2 Using RCA (coaxial) cables, connect the
Mbox Pro S/PDIF In to the S/PDIF output of the
device.
3 Connect the Mbox Pro S/PDIF Out to the
S/PDIF input of the external device.
4 Be sure to read the next section for important
information.
Using S/PDIF Input
In Pro Tools, you can record or listen to an ex-
ternal digital device that is connected to
Mbox Pro’s S/PDIF Input connector. Pro Tools
must first be configured to enable the S/PDIF In-
puts.
Refer to this section whenever you plan to use
S/PDIF input on Mbox Pro.
To enable the S/PDIF inputs on Mbox Pro:
1 Make sure your have connected the external
digital device to the correct Mbox Pro S/PDIF
connector (In and Out).
There is no RIAA preamp or grounding post
on the Mbox Pro, so connecting a turntable
is not recommended.
Connecting an MP3 player or having some-
thing plugged in to the 1/8-inch mini port
will defeat the RCA input signal.

Multi-pin port for breakout cable input
Use 75 ohm RCA cables (the standard for
digital audio) as other cables (such as home
stereo cables) may have problems.
The following requirement only applies to
using S/PDIF input to record or monitor dig-
ital signals through Pro Tools LE and
Mbox Pro.
Mbox Pro does not support external sync at
88.2 kHz, 96 kHz, 176.4 kHz, and
192 kHz sample rates.
