Chapter 6: I/O Setup 49
To route a Pro Tools output channel pair to
multiple audio interface output ports:
1 Choose Setup > I/O.
2 Click the Output tab.
3 Click the Output selector for an interface
channel pair, just below an audio interface icon.
4 From the pop-up menu, select a physical port
pair (such as Analog 1–2) to route to the corre-
sponding Pro Tools channel pair (such as A 1–2)
in the Path Name column on the left.
5 Start-click (Windows) or Control-click (Mac)
the same Output selector and select an addi-
tional output pair from the same pop-up menu.
The output name updates with a plus sign (“+”)
before it to indicate that multiple output ports
are selected. In the pop-up menu, each physical
port pair assigned to that Pro Tools output pair
is indicated by a check mark.
6 Repeat the above steps to select additional
output destinations.
7 Click OK.
Creating and Editing Paths
The I/O Setup dialog lets you create and custom-
ize signal path definitions.
Paths can be:
• Renamed, for easier identification after
changing or renaming audio interfaces
• Remapped, to or from different sources or
destinations
• Deactivated (or reactivated) to manage un-
available or unnecessary I/O resources
• Deleted
In addition, you can import and export your
I/O Setup configurations as I/O Settings files, as
well as set default path parameters.
The following table lists the available path at-
tributes for each path type.
