Audio Controls and Operation
High tally is a push-and-hold function. If any selection or adjustment is
made on either the MCP or Audio Monitor Panel the AP button will not
toggle when released. Its tally remains as it was before the button was
pushed.
While an AP button is pressed it shows high tally, indicating which AP is
delegated. When one button is pressed, the other
AP 2–4
button tallies do
not change. When the AP button is released, if an adjustment was made,
the AP button returns to its previous tally state. If, while pressing and
holding an
AP 2–4
button, another
AP 2–4
button is pressed, the lower num-
bered
AP 2–4
button operation takes precedence (left side priority).
The following modifications can be made to a single AP (not affecting any
other APs) while in a high tally state:
■
Crosspoint selection of
PGM/PST
and
Audio Only
buttons,
■
PGM or PST Level adjustments (if so enabled in configuration),
■
Ratio
knob control of an Over function,
■
Stereo, L-Mono and R-Mono routing mode selection,
■
Phase inversion of a stereo signal, and
■
Enabling of selected AP meter and monitor output only.
Audio Only PST Buttons
The Audio Only crosspoint buttons—
Audio Only 1
through
Audio Only 4
—
allow selection of Program and Preset Audio Onlies as Overs or Break-
aways for up to four Audio Processors They represent only audio sources
(not associated video as with other
PST
and
PGM
buttons).
Audio Over Operations
If neither the
Video Only
nor
Audio Only
buttons in the
Breakaway
section of the
MMCP are selected, selecting an Audio Control subpanel
PST
button per-
forms an Audio Over (at the recalled level and Over
Ratio
control setting).
(Refer to Audio Ratio Control
PST
button in the Audio
Control subpanel displays high tally to indicate the Audio Over selection.
Any previous Over (for this AP) is dropped. An Audio Over can only be
selected from one of the four Audio Only sources in the Audio Control sub-
panel. Just one Over can be selected; two or more cannot be summed
together.
Selecting another Over drops the first. Re-selecting a selected Over drops
the Over (toggle action). If more than one of the
Audio Only
buttons are
pushed simultaneously, the lower numbered one (left side priority) is hon-
ored. Selection of another primary married or breakaway source drops the
Over.
