Mbox 2 Back Panel Features
Figure 4 identifies each port on the Mbox 2 back panel.
The Mbox 2 back panel has the following fea-
tures:
USB Port
This standard USB v1.1 connector is used to
connect your computer to the Mbox 2. One
standard USB cable is included with your sys-
tem.
The Mbox 2 is compatible with USB 2.0 ports.
However, the USB 2.0 bus will switch to the
slower USB v.1.1 speed to accommodate
Mbox 2.
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 2 be used as a 4-in/2-out
digital audio interface for Pro Tools LE.
The S/PDIF output channels always mirror the
main outs 1–2.
