Section 5 — Basic Operation
Bus
The Bus Crossbar is used to select key and fill signals as well as sources for
AUX 1 to 3.
Background
The Background Crossbar indicates which signal is selected as the current
background picture. Pressing another key in this row performs a hard cut
to another background picture. The selected background picture can be
viewed on the corresponding program monitor.
Background Preset
The Background Preset Crossbar is used to pre-select and indicate the
background involved in a signal transition. The preset background picture
and the selected modifications (for example, keys) can be viewed on the
corresponding preview monitor.
The background and preset buses operate in “Flip-Flop” mode. After the
background transition is complete, the preset source is automatically
selected on the background bus and the original background source is
automatically “flipped” to the preset bus.
5.1.5 Main Transitions Subpanel with Transition Lever Arm
The transition controls are used to select the signal elements that will be
involved in the transition (background and/or keys), define the type of

for manual transition control
