Chapter 33: Multichannel Tracks and Signal Routing (Pro Tools HD Only)
777
Multiple output assignments make it possible to
configure a number of multi-format mixes. For
example, you can assign an additional stereo
output to tracks and create a stereo mix at the
same time as a 5.1 mix. For more information,
see “Multiple Output Assignments” on
page 638.
LFE Examples
LFE tracks and other audio can contribute to the
LFE output in two ways:
• Using the LFE fader in Output windows. This
LFE signal is post-fader.
– or –
• Using a custom sub-path to route channels
discretely.
Figure 47 shows a channel Output window,
sending and metering to the LFE channel.
Using the LFE fader, you can add any amount of
any multichannel path to the overall LFE out-
put. In the above example, the track’s Center
percentage has been turned off, and the LFE
fader has been raised to route it to the LFE chan-
nel.
Figure 48 shows how a “traditional” LFE track
can be routed to only the LFE channel. This ex-
ample uses a custom-defined LFE sub-path to
the FX main bus path.
LFE and Filtering
Pro Tools applies no filtering to LFE signals.
Some delivery requirements may require filter-
ing for the LFE track. See the
Pro Tools Sync & Sur-
round Concepts Guide
for more information.

LFE faders can follow Mix and Edit Groups.
