Configuring I/O Setup
Using the I/O Setup dialog, you can label
Pro Tools LE input, output, insert, and bus signal
paths. The I/O Setup dialog provides a graphical
representation of the inputs, outputs, and signal
routing of the Eleven 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 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.
