Clock Source
The Pro Tools Hardware Setup dialog lets you se-
lect the Clock Source for the system.
Internal Use this setting if you are recording an-
alog signals directly into Mbox 2 Pro. When set
to internal, Mbox 2 Pro provides four channels
of input (analog only).
S/PDIF Use this setting to record or listen to
Mbox 2 Pro S/PDIF inputs connected to an ex-
ternal digital device. This setting will synchro-
nize Pro Tools to that digital device.
S/PDIF input is only available when S/PDIF
is the Clock Source.
Although Mbox 2 Pro supports sample rates
of up to 96 kHz, its external clock sources
(S/PDIF and Word Clock) are only sup-
ported in 44.1 and 48 kHz sample rate ses-
sions.
Word Clock Use this setting to clock Pro Tools LE
to a Word clock source connected to the
Mbox 2 Pro Word Clock In port.
Although Mbox 2 Pro supports sample rates
of up to 96 kHz, its external clock sources
(S/PDIF and Word Clock) are only sup-
ported in 44.1 and 48 kHz sample rate ses-
sions.

Your digital input device must be connected
and powered on for Pro Tools to synchro-
nize to it. If your input device is not powered
on, leave the Clock Source set to Internal.
Configuring I/O Setup
Using the I/O Setup dialog, you can label
Pro Tools LE input, output, insert, and bus sig-
nal paths. The I/O Setup dialog provides a graph-
ical representation of the inputs, outputs, and
signal routing of the Mbox 2.
Pro Tools LE has default I/O Setup settings that
will get you started. Use the I/O Setup dialog
only if you want to rename the default I/O
paths.
To rename I/O paths in I/O Setup:
Choose Setup > I/O.
