Derived Group Definitions
The source of the column names used in this section is the Audio Output
table (
page 122 ).
The audio input table is designed to provide mapping of audio channels
from a source to the audio output groups as defined in the Audio Output
table. Software version 1.3 and above fully implement the Audio Input
tables. Previous versions were hard coded in a 1:1 channel mapping.
Many different Audio Input tables are allowed; theoretically, every source
feeding the Maestro switcher could have a different Audio Input table. It
is recommended that a small set of standard audio input tables be created
and used for most sources. A few specialty tables can then be created if
special audio mapping is required.
The Audio Input tables provide “static” channel remapping, meaning that
the audio channels are mapped in configuration and are set in advance. On-
the-fly or “dynamic” remapping is accomplished through the audio group
drill-down screens or the Channel Mapping Screen. The decision as to
which to use depends upon planned operation and philosophy of a given
installation.
Note Input mapping of audio sources is done completely within the Maestro Pro-
cessor. This is especially useful for embedded sources where the audio and
video are locked together. When an external audio router is used, some
mapping functions can be done in the router rather than in the Maestro
product. Careful planning must be done to determine where the mapping is
best done in a given installation.
