poses (AES, embedded, etc). If only one mono audio group is defined, the
Maestro processor will always use the first channel of an audio pair. The
second channel can be used for another mono audio group or it can be left
empty. The empty audio channel cannot be used by any other audio group
type.
Stereo
A stereo audio group always uses two audio channels; when selected, the
second audio channel will automatically be associated with the first
channel.
Maestro can also handle Dolby E or other non-audio signals in a stereo
audio group. The presence of a non-audio bit stream is automatically
detected and will then bypass the audio processing hardware. This step
ensures that the signal cannot be disturbed or destroyed. The hardware will
automatically revert to normal operation if a normal audio signal is fed to
the Maestro Processor.
A forced pass-through can be configured by setting the Force PassThrough
mode in the Audio Output table to “true.” The Force PassThrough mode
will inhibit any gain or balance adjustments, fading, mixing, or other audio
operations on the audio group whether normal audio is passed or Dolby E
signals are present.
Note For most installations, automatic detection will provide the best signal quality
(that is, when Force PassThrough is set to “false”). “False” is the recom-
mended setting as setting Force PassThrough to “true” will disable all audio
level adjustments even on valid audio signals.
Dolby 5.1
The Dolby 5.1 audio group will reserve six contiguous audio channels and
then support them in a recommended channel order as defined below. The
three pairs of audio channels are always assigned on pair boundaries in the
table.
Dolby E PassThrough
The purpose of this group type is to provide a full time Dolby E channel
that cannot be altered, faded, or mixed in any way.
Note This group type is not fully implemented. Operation status reported back to
the control panel is incorrect and could cause confusion. Until such time as
this group type is fully implemented, the Stereo group can be configured for
pass through operations as explained above.
