Section 2 — Basic Maestro Operation
Note In version 1.5 and earlier, the Clean Feed signal is identical with the program
output and contains no audio overs. As documented on
page 247 , version
1.5.1 includes the ability to mix audio overs to the clean feed output
When the Off Air soft button is selected, the Off Air Input monitor point will
be selected. The Off Air input is a dedicated rear panel input on the Maestro
Processor and only has eight channels arranged in four AES pairs. Nor-
mally, the eight channels follow the same audio group assignments as the
first eight channels defined in the Audio Output table.
Mix 1
When the Mix 1 soft button is selected, the source that is assigned to the first
Mix button located to the right of the VGA display is selected and displayed,
and monitored (counting left-to-right).
Pressing the Mix 1 soft button a second time will display Mix 1/(PGM). In
this mode the program bus is monitored, with the mix-over ratio appearing
on the left-most position along the bottom of the VGA display. The control
allows the user to adjust the mix-over ratio while monitoring the actual mix
on the Program bus. This is normally not done as it is preferred to make
level adjustments on the Preset bus and then transition the mix to Program.
Pressing the Mix 1 soft button a third time will display Mix 1/(PST). In this
mode the Preset bus is monitored, with the mix-over ratio appearing on the
left-most position along the bottom of the VGA display. The control allows
the user to adjust the mix-over ratio while monitoring the actual mix on the
Preset bus.
Mix 2 / Mix 3 / Mix 4
These buttons operate the same as the Mix 1 button described above.
