4-M/E Main Panel
Keyer Transition Controls
Each keyer has its own cut and mix transition system, separate from the
main M/E transition mechanism. Individually numbered
Key 1-4 Cut
and
Key 1-4 Mix
button pairs located to the right of the
Transition Lever Arm
control
these transitions. These buttons can directly change the output of the M/E.
A
Key Cut
button can be pressed at any time to cut a key on or off. If pressed
when the button is lit, it cuts the key off. If pressed when the button is off,
it cuts the key on. If a keyer is part way through a transition, pressing its
Key Cut
button will complete the transition, cutting the key either on or off,
depending on the direction of the transition. The
On
indicators below the
Key 1-4
buttons show what keys are actually visible on the output. Note that
these indicators may not match the state of the
Key Cut
button. When a key
is mixed on, the
On
indicator illuminates at the start of the mix transition,
and the
Key Cut
button illuminates when the transition completes. With
preset black, half way through the transition the
On
indicator will be off and
the
Key Cut
button will be on. In this case, pressing a lit
Key Cut
button
ensures the key will not be visible on the M/E output, and pressing an unlit
Key Cut button ensures it will be visible when the preset black completes.
The
Key Mix
buttons can be used to mix a key on or off. The transition will
mix to the opposite state (mix on if the key is off, mix off if the key is on).
Key Mix
button tallies do not indicate whether a key is on or off, but light to
indicate a key mix transition is in progress.
The same keyer cannot be used for both a main transition and a keyer mix
simultaneously. For this reason, the
Key Mix
buttons are inactive when a
main transition is actually in progress. The
Key Mix
buttons remain active,
however, when that keyer has been selected for the next main transition (as
long as the main transition hasn’t been initiated). While an individual
Key Mix
transition is in progress, the
Key 1-4
transition element buttons
involved will go low tally to show a conflict exists. If a main transition is
initiated in this state, the main transition will proceed but that keyer will be
excluded from that transition. Each independent keyer has its own mix
transition rate. See
for more information.
Note that
Preset Black
has higher priority than the keyers. If
Key Cut
or
Key Mix
is pressed while in preset black, the program output will remain black but
the state of the key will change (shown by the Key On indicator lights) and
the change will become evident when the preset black transition completes.
Transition Rates
Auto transition rates for M/E 1, 2, and 3 are set using the respective
Trans Rate
button and keypad located on that M/E’s E-MEM subpanel.
Rates for PGM PST are set using the
Trans Rate
button and keypad located
on the Master E-MEM subpanel.
