Source Name Displays
The source name displays use labels to represent the switcher’s external inputs or internal
sources. Labels for the 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.
The displays show the labels for each row of buttons in the source select row, program row, and
preview row.
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.
Simultaneously pressing both SHIFT buttons next to the source select and program rows will
change the source names display to show protected sources, and these are available in the
source select row for keyers and 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 a 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.
Source Select Bus
The source select bus works in conjunction with the source names display and is used to assign
sources to auxiliary outputs and keyers. When the macro button is enabled, this row of buttons
is also used for loading and running macros recorded to the corresponding slots. The buttons
will illuminate blue when the macro button is enabled.
The 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.
