Program, Preset and AUX Buses
The following discussion assumes that the “NEXT Transition” selection is
Upstream . For more information concerning Upstream vs. Downstream
operation see page 240 .
Selecting a Source on the Program, Preset and AUX (Background)
Buses
Maestro has three main buses: Program (PGM) or Air, Preset (PST), and
AUX (optional). Preset is used to prepare sources to be put on Program.
AUX is used to select a second video source for DVE effects if the optional
DVE mezzanine board is installed. These buses are primarily controlled by
the three rows of 16 buttons across the Source Control panel.
The name of each source (For example, VTR1, CAMERA 1, BARS, and so
forth.) is displayed on the
Program bus buttons.
The Program buttons should be used rarely. Events are should be set up on
the Preset bus and then a transition executed with the Take button; this
process is described in detailed below.
The AUX bus also allows preview of an assigned source without disrupting
the current Preset bus selections (so as not to interfere with automation).
Assigning a Source to a Program/Preset/AUX Button
Each of the Program/Preset/AUX (background) buttons can be assigned to any
source feeding the associated Routing switcher (e.g., Concerto, Trinix, etc.).
Note The source assignment is made by selecting the PST button to which the
source should be assigned while in Source Assign mode. The name of the
source appears on the PGM LCD button. The PST button below and the AUX
button above the source named on the PGM button refer to the same source
on those other busses.
Assignment of sources to buttons can be made using the Source Assign
panel:
