Sub-paths have been defined for Mix, Music,
and FX main output paths.
Additional stereo output paths, with mono sub-
paths, have also been defined for the remaining
channels.
Example Bus Paths
Figure 18 shows example bus paths.
Figure 18. I/O Setup, example bus paths
An LCR format path ("Dialog") and two 5.1 for-
mat paths ("Music" and "FX") have been de-
fined, each with several sub-paths.
Example Sub-Paths
Sub-paths let you route to selective channels
within the multichannel surround output. In
Figure 19, the Mix 5.1 bus has several sub-paths
that show this.

5.0 Sub-Path The 5.0 path is a 5-channel sub-
path. Use this type of sub-path routing to con-
serve mixing resources with tracks you want to
keep out of the LFE channel.
LFE Path A custom LFE sub-path ("Lf") has been
added to provide a discrete mono path for the
LFE channel.
