When Mode 4 (Individual Bus Iso Tally) is selected, the remaining six banks of
switches on the board (Switches S2–S7) select the switcher’s internal buses to be
used as tally sources (see
). For example, with the Bus Enable switches set
for buses 35 and 36 ON, if an input were selected on bus 35 or 36, its corresponding
relay would close. The same input chosen on other buses would cause no relay
closures. It is possible to tally as many buses as desired simultaneously.
When Mode 5 (Look-Ahead Tally) is selected, the switcher tallies the source(s) that
will be on air after one of the following transitions:
■
Flip-Flop Mix/DSK Cut
■
Flip-Flop Mix/DSK Auto Transition
■
Flip-Flop Mix/DSK Lever Arm Transition
