Figure 25. Crossbars for Bus and Source Selection
Note Use the Shift buttons to access numbers 11 to 20 on the Bus, Background,
and Background Preset Crossbars.
By default, the buttons 1 to 10 and Shift+1 and Shift+2 correspond to the
sources IN01 SD to IN12 SD , the buttons
Shift+3
to
Shift+10
correspond to
Stills 1 to 8 (for button assignment see also Control Panel Submenu on
page 135).
Bus
The Bus Crossbar is used to select key and fill signals as well as sources for
AUX 1 to 3.
See Delegation Subpanel on page 39 for information on the types of buses
that can be assigned to the crossbar and how to select them.
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.
