Mbox Back Panel Features
Figure 2 identifies each port on the back panel of the Mbox.
The Mbox back panel provides the following:
USB Port
This standard USB connector is used to connect
a USB 2.0 port on your computer to the Mbox.
One standard USB cable is included with your
system. (It is also used to power the unit in
stand-alone mode.)
MIDI I/O
The MIDI In and MIDI Out ports are standard 5-
pin MIDI ports, each providing 16 channels of
MIDI input and output.
S/PDIF Digital I/O
The S/PDIF in and out ports are unbalanced two-
conductor phono (RCA) connectors that utilize
a full 24-bit, two-channel digital data stream.
The Sony/Philips Digital Interface Format
(S/PDIF) is used in many professional and con-
sumer CD recorders and DAT recorders. To
avoid RF interference, use 75-ohm coaxial cable
for S/PDIF transfers and keep the cable length to
a maximum of 10 meters.
In use, the S/PDIF input channels are available
in addition to the two channels of analog audio
input. This lets Mbox be used as a 4-in/4-out dig-
ital audio interface for Pro Tools LE.
Line Outputs
These outputs support balanced TRS, or unbal-
anced TS, 1/4-inch connections. To monitor
your mix, these outputs can be connected to a
mixing board, directly to a monitoring system
such as a stereo power amp, or another stereo
destination.
