Configuring I/O Setup
The I/O Setup dialog provides a graphical repre-
sentation of the signal routing for each con-
nected audio interface, with controls to route
physical ports on the audio interface to
Pro Tools inputs and outputs. These controls
mirror the routing controls found in the Hard-
ware Setup dialog—changes made to physical
routing in one dialog are always reflected in the
other.
The I/O Setup dialog lets you label and map
Pro Tools input, output, insert, and bus signal
paths. The I/O Setup dialog also provides impor-
tant audition, meter, and surround settings. For
more information, see Chapter 6, “I/O Setup.”
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
Hardware Setup dialog.
For example, if you assign Channels 1–2 to both
outputs Analog 1–2 and Analog 3–4, when you
send a signal to Pro Tools Channels 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).
To route a Pro Tools output channel pair to
multiple audio interface output ports:
1 Choose Setup > Hardware.
2 From the Peripherals list, select an interface.
3 Click the Main tab.
4 Select an output port pair from an Output pop-
up menu.
5 Start-click (Windows) or Control-click (Mac)
the same pop-up menu a second time to choose
another available Output Port pair.
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. The only limit to output
choices is the number of outputs available in
your system.
Pro Tools output pairs can also be routed to mul-
tiple audio interface outputs in the I/O Setup di-
alog. For more information, see “Routing Hard-
ware I/O to Pro Tools I/O” on page 64.
Only currently unassigned Output Port pairs
are available.
