Sources active on the Program bus are sent to the Program output. This is
typically the output being supplied to the station transmitter. In routine
operation, sources are preset on the Preset bus, then transitioned to the
Program bus.
When a transition is made with the
PreRoll/Transition
button, or automation,
sources selected on the Preset bus are transitioned to the Program bus, and
PGM
button tally changes accordingly. For fade-type transitions,
PGM
