Maestro RCS Interconnection
This column shows a software-generated list of all Maestro inputs. This list
refers to the connectors on the rear panel.
BkgdA-C
BkgdA, BkgdB, and BkgdC are the inputs for the Pgm, Pst and Aux
buses; however, there is no one-to-one relationship between an input
and a Maestro bus. For example, the selected source on the Pgm bus
could be routed to Maestro through the BkgdA, Bkgd B or Bkgd C
input, as needed. The same is true for the sources selected on the Pst
and Aux buses.
Bkgd D
This input is used to route a source which contains embedded audio for
use in an audio breakaway. Embedded audio is contained in the video
source and requires a video input. If the BkgdD interconnection is not
defined, audio breakaways with embedded audio will not be available.
