Source Names Display
The source names display uses a 4 character label to represent the switcher’s external inputs or
internal sources. Labels for the 8 external inputs can be edited on the settings window of the
software control panel. Labels for the internal sources are fixed and don’t need to be changed.
Pressing the SHIFT button will change the source names display to show extra sources, called
shifted sources, allowing selection of up to 20 different sources.
When aux has been selected in the system control block, pressing the SHIFT and CUT/FILL
buttons simultaneously will change the source names display to show protected sources,
available for routing to auxiliary outputs. Protected sources are program, preview, clean feed 1
and clean feed 2.
Program Bus
The program bus is used to hot switch background sources to the program output. The source
currently on air is indicated by a button that is illuminated red. A blinking red button indicates
that the shifted source is on air. Pressing the SHIFT button will display the shifted source.
Preview Bus
The preview bus is used to select a source on the preview output. This source is sent to
program when the next transition occurs. The selected source is indicated by a button that is
illuminated green. A blinking green button indicates that the shifted source is on preview.
Pressing the SHIFT button will display the shifted source.
SHIFT
The SHIFT button provides a global shift and is used to shift the program, preview,
and select busses along with the label. It also provides a shift for the transition type and
joystick and other menu functions.
Double-pressing buttons in the preview and select busses, as well as the transition
type buttons, is the same as shift-selecting them and can be a faster way to shift-select
buttons. Double-pressing is not implemented for the program bus as it would cause the
program output to momentarily show the wrong source.
Destination Display and Select Bus
The destination display works in conjunction with the source names display and select bus and
is used to assign sources to auxiliary outputs and keyers.
The 8 character destination display and select bus together show you the routing of sources to
keys and auxiliary outputs. The currently selected source is indicated by an illuminated button.
A blinking button indicates a shifted source. A green illuminated button identifies a protected
source. Protected sources are program, preview, clean feed 1 and clean feed 2.
CUT/FILL
When a key setup menu is selected and the CUT/FILL button is pressed, the destination
display and select bus change to show the currently selected cut signal (also known as
the Key signal) for that key. When selecting sources for auxiliary outputs, pressing the
CUT/FILL button along with the SHIFT button displays program, preview, clean feed 1
and clean feed 2 as sources for selection on the select bus.
