Fader lever operation in bus fixed mode
• In the bus fixed mode there is a fixed relationship between the position of
the fader lever and the signal output on each 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 the transition affects two or more of key 1, key 2 and the
backgrounds, the transition cannot be effected unless all are in accordance
with the table above.
• If, because of an auto transition for example, the fader lever position
becomes out of synchronization with the signal outputs as indicated in the
table, the fader lever must first be moved to the correct position before it
affects the transition state. This non-sync movement has no effect on the
video output.
