Audio Controls
These channels are switched, mixed, faded, monitored and metered as a
single audio program. Adjusting the level control will simultaneously
affect all six channels. Six channel mix-overs are also possible for this group
type. Normally, if surround signals are not present, the two front channels
act as a normal stereo pair. Signals can be mapped into the Dolby 5.1 sur-
round group using the Audio Input tables or remapped on-the-fly using
the drill-down screens (See discussion below on drill-down screens).
If a Dolby E signal is applied to any of the audio pairs of the a Dolby 5.1
surround group, it will be detected and the Maestro Processor will pass the
signal intact on that pair while turning the audio group soft button RED as
it does for stereo group types.
Note The functions described for Dolby 5.1 drill-down screens ( page 222 ) are
functional only for Dolby 5.1 audio groups that are mapped 1:1 in the Audio
Input tables. If the Audio Input tables are used to map other channels into the
Dolby 5.1 audio group output, the drill-down remapping functions are not
functional even though the soft buttons appear on the left side of the VGA dis-
play. This will be corrected in a future software release.
Level Controls Cluster
Located below the Meter display is the level controls cluster. There are soft
buttons and labels associated with each control. These controls are specific
to an audio group type and will change depending upon which audio
group type is selected in the audio group selection cluster.
The right-most position is reserved for audio level or gain control regard-
less of the audio group type.
The left-most position is reserved for mix-over level control regardless of
the audio group type selected. The name of the function assigned to each
control is shown on the soft label above the control. A reset or default
button is located directly above the control which sets the control to the
default value.
On the GUI display, the controls are blanked out or removed if they are not
available for use for a particular audio group type. On the hardware
control panel, the soft display directly above the control is blanked out
when the control is unavailable.
Status Display
Above the audio meters is a text status display. The first line always shows
/ . The second line shows the status of the
Maestro input source name that is selected on either the Program or Preset
