The Pan controls how the Group signal is shared
between the Left & Right main mix buses when sub-
20

Group Sub Routing
OO

The L-R switch routes the panned Group signal to
the main LR mix and the M switch routes the un-

GRP
panned Group signal to the mono bus.
If you want to set up a stereo pair of sub-groups and
route them to the main LR mix, make sure the odd
numbered Group is panned Left and the Even Group
is panned Right.
