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.

For an overview of the bus fixed mode, see “Flip-flop mode and bus fixed mode” (page 33).

•When a transition applies to a combination of more than one of the background and keys 1, 2, 3, and 4, 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 (see page 194) and LEDs light at both end positions of the fader lever travel. Moving the fader lever does not carry out a transition, but when the fader lever reaches the end position the non-sync state is released, and it is now possible to carry out the next transition. If the fader lever is moved in the direction away from the lit LEDs, this carries out the next transition, over the remaining part of the fader lever travel.

The direction of a wipe is also in a fixed relationship to the fader lever movement direction.
