Control Panel Descriptions
2) Program Bus
The Program Bus (PGM) is the bank’s bottom layer, which is used to select the
switcher’s primary output video. Please note:
~ Except for SHIFT, all buttons on the PGM Bus are mutually exclusive,
including the re-entry button.
3) Preset and Phantom Key Bus
This bus has three functions:
~ The PST Bus is used to select the next background source.
~ Because there is no physical Key Bus in the PGM Bank, the PST Bus
doubles as the bank’s “phantom” key bus for the downstream keyer. To
assign a key source, press and hold the DSK button, select the desired
key source from the buttons on PST, then release the DSK button.
~ When a DVE channel is assigned to the DSK, the phantom key bus
enables you to select the input to the DVE channel — in the same
manner that DSK sources are selected.
Please note:
~ Except for SHIFT, all buttons on the PST Bus are mutually exclusive,
including the re-entry button.
~ When a PST source is taken to Program with a transition, the source
“flips” to PGM. In Chapter 7, refer to the “Understanding Flip-flop
Mode” section on page 314 for details.
4) Re-entry Buttons
At the end of each bus, the Re-entry Button allows you to combine the program
output of the M/E into the video flow of the selected bus. For example:
S You can re-enter M/E 1 on PGM, PST or the Phantom Key Bus.
This re-entry capability enables you to cut, mix or wipe to an M/E, or use an M/E
as a key source.
5) SHIFT Buttons
All SHIFT buttons are latching. Press to access additional sources as follows:
~ Sources 11 through 20 on the FSN-150.
In Chapter 7, refer to the “Understanding Switcher Layers
” section on page 312 for a
discussion of video layers within the switcher.
Note
The Re-entry Button can be mapped, using the Map
Buttons Menu. For example, if M/E control is enabled on the
FSN-150, you can map M/E 2 onto the “shifted” M/E re-entry
button. In Chapter 5, refer to the “Map Buttons Menu
”
section on page 224 for details.
