Bus fixed mode and bus flip-flop mode
The default operating mode for the switcher is bus flip-flop mode, in which
an M/E background transition always proceeds from background A to
background B, and at the end of the transition the signal selections on the two
background buses flip-flop. This means that except during a transition it is
always background A which feeds the output of each of the mix/effects
banks, and always a background A bus tally indicator which is lit.
The DVS-7300/7350 system can also, however, operate in bus fixed mode.
This treats the two background buses A and B equally: a transition may go
from A to B, or back from B to A, and there is no automatic flip-flop. In this
case the fader lever position also has a fixed relation to the output: 100%
background A when it is at the top, and 100% background B at the bottom
position.
To select the bus flip-flop mode or bus fixed mode, set the BUS TOGGLE
item in a setup menu (page 13-73): "ON" for bus flip-flop mode and "OFF"
for bus fixed mode.
