Midi Connections - DigiDesign Mbox 2 Pro Getting Started Manual

Using S/PDIF Input
This section describes the steps you must take
once you have finished installing and launching
Pro Tools LE to enable the S/PDIF ports for digi-
tal input.
Refer to this section whenever you plan to use
S/PDIF input on Mbox 2 Pro.
The following requirement only applies to
using S/PDIF input to record or monitor dig-
ital signals through Pro Tools LE and
Mbox 2 Pro.
In order to record or listen to a digital device
connected to the Mbox 2 Pro S/PDIF In connec-
tor, you must do the following to configure the
Pro Tools Clock Source:
To enable the S/PDIF inputs on Mbox 2 Pro:
Make sure your have connected the external

digital device to the correct Mbox 2 Pro S/PDIF
connector (In and Out).

that it is set to the correct sample rate, and that
it is configured to provide S/PDIF clock (if rele-
vant to your device).

Enabling S/PDIF Input in the Hardware Setup dialog
40 Mbox 2 Pro Getting Started
Once enabled in the Hardware Setup dialog, the
S/PDIF inputs become active and will pass audio
to Mbox 2 Pro.
Setting the Clock Source to S/PDIF is the only
way to utilize S/PDIF input. Doing so lets you
record or monitor up to six discrete input chan-
nels (the four analog input channels, plus the
two channels of S/PDIF input).
Selecting any other Clock Source (Internal,
or Word Clock) disables S/PDIF input.
S/PDIF output remains available.

MIDI Connections

The two MIDI ports on Mbox 2 Pro let you take
advantage of all the MIDI features of
Pro Tools LE, including recording and editing
MIDI tracks.
If you need additional MIDI ports you can add a
compatible MIDI interface. USB MIDI interfaces
work effectively with Pro Tools systems on Win-
dows or Mac. Serial MIDI interfaces are sup-
ported on Windows systems only.
Only USB MIDI interfaces are compatible
with Pro Tools systems for Mac OS X. Mo-
dem-to-serial port adapters and serial MIDI
devices are not supported.
To connect MIDI devices to Mbox 2 Pro:
Connect the MIDI OUT of your MIDI device
1
or controller to the MIDI IN port on the back of
Mbox 2 Pro.
