is post channe! volume.
ePanpot Controls
The Panpot Control routes the input
signal from an Input Channel to the left
and/or right mixing busses. By means of
the Panpot Controis, input signals can be
sent exclusively to one mixing bus, or
the other, to both mixing busses equally,
or since the Panpot Control is continu-
ously variable to both mixing busses in
any relative proportion desired.
