9.1 Principles
The Stack facility enables a pre-programmed series of Cues to be
‘taken’ in the form of a cross-fade. Each cross-fade can be
performed automatically over a preset timed period, or controlled
manually.
Hint Stacks are particularly useful for controlling theatre lighting: each
Cue is programmed and then simply called up at the correct
moment during the performance using only the press of a key.
Also, in rock’n’roll and discotheque lighting the Stack can be used
as a sophisticated Sequence with different time intervals.
The Navigator console supports four Stacks – each of which can
contain up to 99 entries – although only one of these may be
operating at any one time.
Hint In the same way that Sequences control channels, Stacks can be
thought of as controlling Cues.
9.2
Programming a Stack
To program a Stack, proceed as follows:
1 Program all Cues that are to be used in the Stack.
2 Move to the “[STORE] [STACK]” menu:
This menu displays a number of items:
– Stack number.
– Entry number.
– Cue number for ‘take’.
– Time to fade.
To changes the values of these items use the [>] and [<] soft
buttons to move the cursor to the required field, and rotate the
Master Select to increment or decrement the value accordingly.
