CR Path Channel Assignments to Physical
Outputs
The CR Path channel assignments are created
and edited just like in the Pro Tools I/O Setup
(for more information about I/O Setup, see the
Pro Tools Reference Guide ).
The number of CR Path channels depends on
the selected Format (channel format). For exam-
ple, when the CR Path format is set to 5.1, the
CR Path consists of 6 channels: L (front left), C
(center), R (front right), Ls (left surround), Rs
(right surround), and LFE (Low Frequency Ef-
fects). A 5.1 CR Path can be assigned to any 6
available physical outputs. In Figure 7 on
page 32, the MAIN CR Path is 5.1 and each
channel is assigned to the physical outputs of
Analog (DB-25) channels 1–6.
Uneven channel formats make the next even
numbered channel unavailable. This is because
output channel paths are always paired. For ex-
ample, LCR occupies output channels 1–2 and
3–4 (with 4 unavailable), and 5.0 occupies out-
put channels 1–2, 3–4, and 5–6 (with 6 unavail-
able).
Once CR Path channels are assigned to physical
outputs, the “Monitor” path is displayed in the
Output selectors on the Main page of the Hard-
ware Setup and in the I/O Setup. The individual
physical outputs used by the MAIN and ALT
Control Room monitor assignments are itali-
cized in the I/O Setup, indicating they are in use
and unavailable for other output assignments.
Note that any signal routed to the “Monitor”
path from Pro Tools tracks plays out the corre-
sponding assigned physical output according to
the MAIN and ALT assignments.
LCR monitoring determines the available Hardware
Setup Output assignments, and I/O Setup Output
path assignments
At sample rates higher than 96 kHz, the
Optical S/PDIF Digital output is grayed out
and unavailable as a monitoring path in
the Hardware Setup.
