Chapter 5: Configuring Your Pro Tools System 23
Pro Tools Hardware Settings
In the Hardware Settings dialog, Pro Tools lets
you set the default sample rate and clock source
for your system, as well as a range of controls
specific to each type of audio interface.
Default Sample Rate
The Sample Rate setting appears as the default
sample rate when you create a new session.
(This setting is available in the Hardware Setup
dialog only when no session is open.)
To change the default Sample Rate:
1
Choose
Setup > Hardware
.
2
Select the sample rate from the Sample Rate
pop-up menu.
3
Click OK.
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.
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.
To select the Clock Source:
1
Choose Setup > Hardware.
2
Choose the clock source from the Clock
Source pop-up menu.
3
Click OK.
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.
You can change the sample rate when creat-
ing a new Pro Tools session by selecting a
different sample rate in the New Session
dialog. (Refer to
the Pro Tools Reference
Guide for details.)

S/PDIF input is only available when S/PDIF

nize to it. If your input device is not powered
on, leave the Clock Source set to Internal.
