Section 2 — System Operations
At the effective time of the transition cut (considering preroll, transition
hold and transition now), the old Program Over and ratio are immediately
replaced with the new Over source at its associated ratio. The main source
is unchanged.
The audible result is an immediate cut to new Over source at its ratio. The
panel tally will be immediate.
Cut Transition—Cut to New Over and Change Main Source
Conditions:
■ Change in audio Main source
■ Over currently on Program bus
■ Over is on Preset bus
Identical to cut an Over on and change main source: this audio cut is
treated as a fade-fade and the ratios are not changed during the transition.
Hot Cut Transition 1
Conditions:
■ Change Program Main source
■ Over was on Program bus
The new Program main source will be selected immediately and will high
tally on the panel. Over the FTU interval the ratio of the Over source is tran-
sitioned to zero, at which time the Over source is removed and the panel
tally is removed.
The audible result is an immediate cut of the main source but at the pre-
existing ratio (not full level, Over will still be present). Over the FTU
interval the new main source is faded up to full level and the Over is faded
to zero. The Over is then removed and the Over panel tally is removed.
Hot Cut Transition 2
Conditions:
■ Hot cut on an Over on the Program bus
■ No Over currently on Program bus
The new Program Over source will be selected immediately and will high
tally on the panel. If the ratio associated with the Over source is greater
than 50%, then the ratio is set to 50% immediately at cut-in time and is tran-
sitioned to the final ratio Over the FTU period. This yields the effect of a
constant Over level, with the main level fading under to its final level
which is dictated by the ratio setting.
If the ratio associated with the Over source is 50% or less, than an imme-
diate cut is done to this ratio.
