5.1 Tracks, Formats, Mapping, and
Metering
Path definitions in I/O Setup determine how au-
dio is routed through, and metered on, your au-
dio interfaces.
Pro Tools internal (on-screen) metering of 5.1
format paths always follows the Film track lay-
out:
L C R Ls Rs LFE
Pro Tools track layout of 5.1 format audio tracks
in the Edit window also conforms to the Film
layout (arranged top to bottom). See the illustra-
tion “5.1 Track Layouts, Routing, and Metering”
on page 764
.
In the I/O Setup dialog, you can route these sig-
nals out of your audio interfaces according to
any track layout (such as DTS or SMPTE/ITU).
To re-map channels in a path:
■ Click and drag a channel to a new valid loca-
tion in the Grid. Other channel assignments
will move (shuffle) to accommodate dragged
channels.
