Chapter 2: Windows Configuration 17
Clock Source
Using the Hardware Setup dialog, you can select
the clock source for the system. If you are re-
cording directly into Pro Tools, you will usually
use the Internal setting. If you are transferring
material from an external digital device, select
the corresponding clock source. (See “Recording
a Digital Source” on page 17.)
To select the clock source:
1 Choose Setups > Hardware Setup.
2 Choose the clock source from the Clock
Source pop-up menu.
3 Click OK.
Recording a Digital Source
If you are recording from an optical or S/PDIF
device, you will need to select a Clock Source. In
most cases, you will synchronize the Pro Tools
clock to the external device.
To configure Pro Tools LE for a digital source:
1 Connect an ADAT or Optical S/PDIF format
device to the Optical In connector, or an RCA
S/PDIF format device to the RCA S/PDIF In con-
nector on the back of the Digi 002.
2 Choose Setups > Hardware Setup.
3 Make sure the correct digital input option is
selected for your setup. When you select RCA
S/PDIF, the Optical ports are available for stan-
dard ADAT Optical (or “Lightpipe”) input.
When you select Optical S/PDIF, the RCA digital
input connector is inactive.
4 From the Clock Source pop-up menu, select
Internal if you are synchronizing the external
device to Digi 002 or Digi 002 Rack. If you are
synchronizing the Pro Tools clock to the exter-
nal device, select ADAT, RCA (S/PDIF) or Optical
(S/PDIF), depending on where you connected
your digital device.
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 Digi 002 and
Digi 002 Rack.
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.
Your digital input device must be connected
and turned on for Pro Tools to synchronize
to it. If your input device is not turned on,
leave the Clock Source set to Internal.
You can use only one pair of S/PDIF inputs
(either RCA or Optical) at a time.
Your digital input device must be connected
and powered on. If your input device is not
powered on, leave the Clock Source set to
Internal.
