state is released, and it is then possible to execute a 
transition.
• If the fader lever is moved in the direction away from the 
lit/flashing LEDs, the transition is executed over the 
remaining part of the fader lever travel.
• Even in a non-sync state, you can execute an auto 
transition. During auto transition execution by pressing 
the [AUTO TRANS] button (or [TAKE] button), the 
transition indicator shows the transition progress in the 
usual way, but when the transition completes, they once 
again indicate the non-sync state.
The transition indicator display state (lit or flashing) is set 
in the Setup menu (see page 432).
Fader Lever Operation in Bus Fixed 
Mode
Flip-flop mode and bus fixed mode
This section describes flip-flop mode and bus fixed mode 
on an M/E bank, as an example. The functionality is the 
same on the PGM/PST bank.
Normally, when a background transition is executed on an 
M/E bank, the signals selected on the background A bus 
and background B bus 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 between the A bus and B bus 
signals. 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 bus fixed mode, there is a fixed relationship between the 
position of the fader lever and the signal output on the 
background A bus and background B bus. When executing 
a manual transition, the fader lever must therefore always 
be moved in the directions shown in the following table 
according to the transition direction. This does not affect 
Note
If an auto transition is executed 
after moving the fader lever from 
bottom to top and stopping mid 
transition: Bottom two LEDs 
light/flash.
Once the fader lever is 
moved to this position, 
the non-sync state 
ends, and transition 
execution is possible.
If an auto transition is executed 
after moving the fader lever from 
top to bottom and stopping mid 
transition: Top two LEDs light/
flash.
