Audio Controls and Operation
The Primary/Over LED display shows the ratio of an Over to the Primary on
either the Program or Preset bus for the delegated Audio Processor. Its bar
graph display shows the relative values of Over to Primary audio. This
display is delegated to Program or Preset with the following rules:
■ If there is not an Over selected on either bus, it is blank.
■ If the Over ratio adjustment is being performed, the display is dele-
gated to this adjustment.
■ If either the Program or Preset bus has an Over selected, the display is
delegated to that Over.
■ If both Program and Preset buses have an Over selected, the display is
blank.
The Ratio knob is delegated in the same manner as the display. If either but
not both of the buses have an Over selected and the display shows the ratio
for that bus, the
Ratio knob is controlling that ratio. It is acceptable to press
and hold a Program or Preset Audio Only button as described below to adjust
the ratio, even if the Ratio knob is already delegated.
Use of the ratio control is further delegated by pressing and holding a
Program or Preset
Audio Only button for the delegated Audio Processor. If
the Ratio knob is adjusted and the Audio Only button is released, this source
will be or remain selected as an Over, and not toggle off if previously
selected.
For Audio Processor 1, selection of an audio Over on the Program or Preset
bus will recall the audio ratio setting that was in effect the last time that
audio Over was updated. For AP 2–4 ratio recall can be configured.
Audio Ratio Summary Facts
■ The ratio control setting is set to 50% by default.
■ A ratio setting of 0% mixes full Main source with zero Over source.
■ As the ratio is advanced from 0% to 50%, the level of the Over source is
increased from 0% to 100% while the level of the main source remains
unchanged. At a ratio of 50%, both the Main source and the Over source
are contributing 100% of their full level.
■ As the ratio is advanced from 50% to 100%, the contribution of the Main
source is decreased, until it is zero at ratio of 100%. The level of the Over
source does not change.
