Chapter 44: Pro Tools Setup for Surround 979
In addition, the I/O Setup dialog, like the Main
page of the Hardware Setup dialog, provides
controls for routing the physical inputs and out-
puts on your audio interface to available inputs
and outputs in Pro Tools.
Remapping Channels
The I/O Setup dialog and its Channel Grid also
let you remap channels. This is especially useful
to route channels within a multichannel path,
without having to repatch your audio interfaces.
You can remap paths to any required configura-
tion, limited only by your systems resources,
and the I/O Setup dialog requirements for chan-
nel overlapping and naming (see “Valid Paths
and Requirements” on page 71 for more infor-
mation).
Example LCRS Setup
The following example shows one possible way
to configure the I/O Setup dialog to mix in 4-
channel LCRS format, with a 96 I/O.
To define an LCRS path:
1
Choose
Setup > I/O
, and click the
Output
tab.
2
Click
New Path
.
3
Select
LCRS
from the Path Format selector.
4
Name the path LCRS.
5
In the Channel Grid, click in the box below
the first (left-most) audio interface channel for
the path. Pro Tools automatically fills up the ad-
jacent units to the right. If you click in the LCRS
row under channel 1, the LCRS path will be
mapped across channels 1–4.
6
Select the new LCRS path and click
New Sub-
Path
.
7
Name the new sub-path LCR and select LCR as
the Path format. Click in channel 1 in the LCR
row to map the path.
8
Select the LCRS path, click
New Sub-Path
, and
create a stereo sub-path for front Left and front
Right.
9
Select the LCRS path, click
New Sub-Path
, and
create a mono sub-path for the Center channel.
10
Select the LCRS path, click
New Sub-Path
, and
create a mono sub-path for the Surround chan-
nel.
11
Click
OK
to close the I/O Setup.
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
When creating 5.1 format paths, you can
specify the default track layout. See “De-
fault Path Order for 5.1 Tracks” on
page 980.
See also “Example Paths and Signal Rout-
ing for a Surround Mix” on page 990.
