Tektronix 3000 Switch User Manual


 
2-113
Preview/Mask/Aux Bus
The re-entry sources are as follows:
M/E 1, M/E 2, and M/E 3 program outputs
Switcher program (PGM) output
The selected source button is either bright or dim, depending
upon its on-air status. All other buttons in the row are unlit.
Aux 1-4 Effects Send Only Buttons
The Aux 1-4 Effects Send Only buttons select both
video and key outputs. Key outputs must be
associated with selected video sources.
NOTE:
The AUX 1-4 EFFECTS SEND ONLY buttons are functional
only when the Effects Send option is installed. (For Effects Send
operation, the system automatically configures the aux bus pair (A/B) as
a video/key pair. It is not necessary to do this in the Aux Bus Format
menu.)
Preview Only Select Buttons (3000-2 only)
The Preview Only buttons select the desired
preview output to be viewed on the switched
preview monitor. When one of the Preview Only
buttons is pressed, the PVW bus delegate button is
automatically selected if it isn’t already on.
Choices available on the switched preview output are M/E 1
Preview output, M/E 2 Preview output, and DSK (switcher)
Preview output.
