an auto transition, which can always be executed 
regardless of the fader lever direction.
• When a transition uses a combination of more than one 
of the background and key 1 to key 8, 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 of 
each bus, a non-sync state (see page 95) results and 
LEDs light/flash at both end positions of the fader lever 
travel.
Split Fader
Split fader is a function that splits a single fader lever into 
left and right, allowing you to control background A bus 
and background B bus transitions independently.
The fader lever on the transition control block (simple 
type) is split into two by pressing the lock button to unlock 
the two fader levers for use as split faders.
The split fader levers support the following buses. You can 
change the settings in the Setup menu.
• Right fader lever: Background A bus (main)
• Left fader lever: Background B bus
The following conditions must be satisfied in order to use 
the fader lever as split faders.
• Bus fixed mode is set.
• Split faders are enabled.
• Mix or NAM (non-additive mix) is selected for 
transition type.
• If the transition type is a clip transition, Mix or NAM 
(non-additive mix) is selected for the background 
transition type.
If these conditions are not satisfied, only the main 
(background A bus) fader lever can be operated.
For details about split fader settings, see “Setting the Main 
Fader Lever” (page 429) and “Enabling/disabling split 
faders” (page 469).
Split fader operation
The relationship between the position of the fader lever 
and the output for a mix transition type is given below.
The A bus and B bus output for a NAM transition type is 
an image created using non-additive mixing.
The transition indicator displays the progress of the 
background A bus.
