Transition Control
Performing Transitions
The Cut and Auto Trans buttons and the Transition Lever Arm are used to
perform main transitions. After a transition completes, the background
source selections flip-flop, readying the PST bus for the next source selec-
tion. The progress of a transition is indicated by the LED bars beside the
lever arms.
The Cut button instantaneously replaces the selected elements with their
new sources or states, regardless of the transition type selected. The button
will light briefly to confirm the operator's action.
The Auto Trans button starts an automatic transition of a predetermined
rate. The button will light during the transition. Pressing Auto Trans a
second time during a transition stops the transition at that point. The tran-
sition can then be completed by pressing the button a third time or by
moving the Transition Lever Arm to its opposite limit or by pressing the Cut
button.
The Transition Lever Arm is used to manually perform a transition. You can
move the lever in either direction to run a transition due to the flip-flop
architecture of the buses. Moving the lever from one limit to the other per-
forms a complete transition. It is possible to start a transition with the lever,
then stop moving the lever at any point, reverse its direction, and even
return it to the original limit without completing the transition.
If the Transition Lever Arm is not in an end position when recalling an effect
or performing an Auto Trans, the lever arm is resynchronized by recalcu-
lating the resting lever arm way to complete the transition in the direction
of the arrow. Moving the lever arm in the opposite direction enable the
operator to resynchronize the arm to an end position without affecting the
output signal.
Preset Black
The Preset Black button modifies a main transition so that it will go through
black, instead of going directly to the new state. This is an alternate action
button (pressed to turn it either on or off). The Preset Black button lights
when it has been selected.
Two successive transition commands (Auto Trans button, or Transition Lever
Arm action) are used for a complete preset black transition.
The first command transitions the switcher to black (first stage). When in
black, both the PGM and PST bus selections will go low tally. The second
command transitions from black to the final stage, completing the preset
black transition.
The preset black function is canceled automatically at the end of the second
transition.
