Even in a non-sync state, you can carry out auto
transitions. If you execute an auto transition by pressing
the [AUTO TRANS] button, the indicators show the
transition progress in the usual way, but when the
transition completes, they once again indicate the non-
sync state.
Fader Lever Operation in Bus Fixed
Mode
Flip-flop mode and bus fixed mode
The following describes the difference between flip-flop
mode and bus fixed mode, taking an M/E bank as an
example; the functionality is the same, however, on the
PGM/PST bank.
Normally, when a background transition is carried out on
the M/E bank, the signals selected on the A and B rows of
the cross-point buttons are interchanged at the end of the
transition. That is to say, except during a transition, the
background output is always from the background A bus.
This is called “flip-flop mode.”
The alternative is known as “bus fixed mode,” in which
there is no bus interchange. In this mode, when the fader
lever is at the top of its travel the output from the A bus is
always 100%, and when the fader lever is at the bottom of
its travel the output from the B bus is 100%.
In the bus fixed mode there is a fixed relationship between
the position of the fader lever and the signal output on
background A bus and B bus. Depending on the direction
of the transition, the fader lever must therefore always be
moved in a particular direction, as shown in the following
table. This does not affect an auto transition, which is
executed regardless of the fader lever direction.
•
When a transition applies to a combination of more than
one of the background and keys, then the transition for
all of these must be in the same direction complying with
the above table.
•
If as a result of an auto transition, for example, the fader
lever position does not agree with the signal output, this
is a non-sync state
(

p. 72) and the [Non Sync]
indicator will appear.
Transition Preview
With the preview output of the M/E bank and PGM/PST
bank, you can check the effect of a transition in advance.
To carry out a transition preview, press the [TRANS
PVW] button in the transition control block to enable
transition preview mode.
Notes
It is not possible to carry out a transition preview during
the following.

Carrying out a transition preview
1 In the transition control block of a switcher bank, press
the [TRANS PVW] button.
The [TRANS PVW] button lights green, and the
switcher is now in the transition preview mode. At this
point, the preview output is the same as the program
output before the [TRANS PVW] button was pressed.
