Chapter 5: Configuring Your Pro Tools System 25
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 analog inputs
1–2 and/or are recording digital inputs into
Mbox 2 inputs 3–4 where the digital device is
synchronized to the Mbox 2 digital output.
S/PDIF Use this setting if you are recording
through the Mbox 2 S/PDIF inputs from an ex-
ternal digital device. This setting will synchro-
nize Pro Tools to that digital device.
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.
To rename I/O paths in I/O Setup:
1 Choose Setup > I/O.
2 Click the Input, Output, Insert, or Bus tab to
display the corresponding connections.
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.)
