Chapter 6: Configuring Your Pro Tools System 61
Opening the I/O Setup Dialog
The I/O Setup dialog can be opened and config-
ured whether or not a Pro Tools session is open.
To open the I/O Setup dialog:
1 Make sure your audio interfaces are enabled
and configured properly in the Hardware Setup
dialog. See “Configuring Audio Interfaces” on
page 52.
2 Choose Setup > I/O.
Closing the I/O Setup Dialog
To close the I/O Setup dialog and save changes:
 Click OK.
When you click OK, Pro Tools checks several set-
tings for routing validity (to prevent feedback
loops) and notifies you if there is a problem.
To close the I/O Setup dialog without saving
changes:
 Click Cancel.
I/O Settings Pages
The I/O Setup dialog provides tabs to open pages
for configuring the following I/O Settings:
Input Configure input signal path names, for-
mats, and source channel (analog or digital).
Multichannel input paths (stereo or greater) can
have any number of sub-paths. You can have
overlapping Input signal paths. Input names,
channel widths, and physical input mappings
are saved with the system.
Output Configure output signal path names and
formats. You can have overlapping Output
paths. Output names, channel widths, and
physical output mappings are saved with the
system.
Insert Configure insert signal path names, for-
mats, and destinations (audio interface chan-
nels). You can have overlapping Insert paths. In-
sert names, channel widths, and physical input
and output mappings are saved with the system.
Bus Configure internal and output bus signal
path names and formats, and map output busses
to output paths (defined on the Output page).
Multichannel busses (stereo or greater) can have
any number of sub-paths. Output bus and inter-
nal mix bus names and channel widths are
saved with the session. Output bus paths to out-
put channel mappings are automatically gener-
ated depending on the defined session output
bus paths and the available system output chan-
nel paths.
Mic Preamps Map PRE outputs to an audio inter-
face’s inputs to establish communication be-
tween Pro Tools and PRE. PRE channel map-
pings are saved with the system.
