To map all output busses of the same format to an
output path:
1 Do one of the following:
• Shift click to select contiguous Output
busses.
– or –
• Command-click (Mac) or Control-click
(Windows) to select noncontiguous Output
busses.
2 Option-Shift click (Mac) or Alt-Shift-click
(Windows) the Mapping To Output selector for
one of the selected Output busses and select an
Output Path (mono or stereo).
Only the selected mapped output busses of the
same format (such as stereo) are all assigned to
the same Output Path. For example, you can as-
sign only the selected stereo output busses to
output path A 1–2.
To automatically map all output busses of the
same format to unique ascending output paths
(cascading):
 Command-Option-click (Mac) or Control-Alt-
click (Windows) the Mapping To Output selec-
tor of the top-most Output path and select the
first Output Path.
All mapped output busses of the same channel
format are automatically assigned to unique
Output Path assignments in ascending order.
For example, for a stereo output path, Output
Bus A 1–2 is assigned to output path A1–2, A 3–4
to A 3–4, A 5–6 to A 5–6, and so on.
Signal Path Routing for Audio Output
Figure 10 on page 65 shows the signal path from
the output of an audio track, through the output
bus mapped to a physical output on an HD I/O.
Example:
1 Audio is played back from disk and routed
from the Track Main Output to Output Bus
“B 1–2.” The Output Bus is defined on the Bus
page of the I/O Setup.
2 On the Bus page of the I/O Setup, the Output
Bus “B 1–2” is mapped to Output “B 1–2,” which
is defined on the Output page of the I/O Setup.
Also, the Bus page is where you can create
sub-paths for output busses.
3 On the Output page of the I/O Setup dialog,
the Output to which the Bus Output is mapped
is routed to physical outputs on your audio in-
terface.
4 The physical outputs on your audio interface
that are available to Pro Tools outputs are set on
the Main page of the Hardware Setup dialog.
