To configure I/O routing in I/O Setup:
1 Choose Setups > I/O Setup.
2 Click the Input or Output tab to display the
corresponding path type.
3 Click the Input or Output Selector for the first
interface channel pair, located below the first
audio interface icon.
4 From the pop-up menu, select a physical port
pair (such as Analog 1–2), to route to a Pro Tools
channel pair (such as A 1–2) in the Path Name
column on the left.
5 Repeat the above step for additional channel
pairs.
6 Click OK.
Routing a Pro Tools Output Pair to
Multiple Destinations
Pro Tools channel pairs can be routed to multi-
ple outputs on an audio interface through the
I/O Setup dialog. For example, if you assign both
Analog 1–2 and Analog 3–4 interface outputs to
Pro Tools Output pair 1–2, when you send a sig-
nal to Pro Tools Outputs 1–2, that signal will be
routed simultaneously to both pairs of output
ports on your audio interface.
This lets you send the same signal (such as a ste-
reo pair, a stem mix, or a multichannel mix) to
multiple destinations (such as multiple master-
ing devices).
The only limit to output choices is the number
of outputs available in your system.
Pro Tools outputs pairs can also be routed to
multiple audio interface outputs in the Hard-
ware Setup dialog. For more information, see
“Routing a Pro Tools Output Pair to Multiple
Destinations” on page 44.
To route a Pro Tools output channel pair to
multiple audio interface output ports:
1 Choose Setups > I/O Setup.
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 (Macin-
tosh) the same Output Selector and select an ad-
ditional 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.
