Scene Control
The CDC FOUR incorporates a Scene Memory system. This is a “snapshot”
automation system, and allows every audio-related parameter* on the mixer to
be saved as a Scene, named, and subsequently recalled. A Scene may typically
include channels being muted and unmuted, levels being changed, and FX sends
being enabled, but may extend to any mixer function, such as EQ and dynamics
adjustments, routing, FX parameter changes, etc. Up to 999 Scenes may be
saved in this way.
The Scene Memory feature is extremely useful in theatre production work, as
entire sound configurations may be set up and optimised in rehearsal, and
then saved. During performance, the engineer merely has to step through the
consecutive scenes at the appropriate cue to reset the entire mixer to the correct
settings.
* An important exception is the position of the Stereo Master fader; being non-automated, this
remains manual at all times.
Current Scene
An important aspect of the Scene Memory system is that the current status of
the mixer at all times – i.e., the settings of all mixer controls - is constantly being
written into a single memory location, referred to as the Current Scene. This is
a non-volatile memory, and during the mixer’s boot procedure, the contents of
the Current Scene are recalled. This means that if the mixer suffers a temporary
power failure, its last-known state will be automatically reinstated in all respects
when power returns.
When a Scene is saved, the contents of Current Scene is copied into the selected
Scene Memory.
Pressing the SCENE button adjacent to the screen opens the Scene page:
The scenes which have been saved in the mixer’s internal Scene Memory are
displayed in tabular form.
