The PVW button enables the selection of the source to be viewed
on the switched preview monitor. The selection can be any
primary or secondary input, or any of the PVW ONLY crosspoint
sources (M/E 1 PVW, M/E 2 PVW, or DSK PVW) on the 3000-2 or any
of the crosspoint sources selected on the Preview subpanel (PVW
PRI, M/E 1
, M/E 2, M/E 3, or DSK) on the 3000-3.
Mask Bus Selection
Pressing the MASK button in the Bus Delegate group delegates the
source select buttons to select a source for the mask generators.
The MASK button high tallies when the mask bus is contributing
to the switcher Program output.
Aux Bus Selection
Aux buses 1 through 6 can be used as simple video
routing aux buses. In addition, aux buses 1 through 4
can be used for sending video and key to an external
digital device (DPM) or to the internal frame store
(Aux Bus 4 only).
