Configuring I/O Setup
I/O Setup dialog provides tools to label and map 
Pro Tools input, output, bus, and insert signal 
paths.
In addition, the I/O Setup dialog, like the Main 
tab of Hardware Setup, provides controls for 
routing Pro Tools input and output channels to 
the physical ports on your 192 Digital I/O.
Multiple Outputs
Pro Tools output channels can be assigned to 
multiple hardware outputs of the 
192 Digital I/O. You can multi-assign individual 
outputs manually in the Mix or Edit windows, 
or you can define multiple outputs in Hardware 
Setup that are global, and will persist from ses-
sion to session. You can multi-assign any avail-
able 192 Digital I/O outputs in the Hardware 
Setup dialog.
To route Pro Tools channels to multiple 
192 Digital I/O outputs:
1 In the Hardware Setup dialog, click the pop-up 
menu for the Pro Tools output pair you wish to 
multi-assign (for example, 1–2, 3–4, 15–16). By 
default, all pairs are assigned to a 192  Digital  I/O 
output pair; Outputs 1–2 are by default mirrored 
to the two-channel Digital [Encl] pairs. 
2 Select one of the outputs to which you want 
to route the output from Pro Tools.
3 While pressing Control (Macintosh) or the 
Start key (Windows), select each additional out-
put destination.
Selecting multiple output formats does not af-
fect time slot count. The multiplexing of audio 
is done in the peripheral rather than in software 
or the computer.
Refer to the Pro Tools Reference Guide for 
more information on setting up I/O paths.
