Section 2 — System Operations
Audio Processor Delegation
Audio Processor 1 (AP 1), the standard audio processor, is always under
MMCP control except during an AP Breakaway operation. It has no dele-
gation button, as it is always delegated by default. To delegate control of
the Audio Control subpanel or MMCP to Audio Processors 2-4, the Audio
Processor delegation buttons
(AP 2, AP 3, AP 4) ( Figure 2-13 on page 2-41 ) are
used.
The buttons delegate an AP to the Audio Control subpanel and MMCP
control for setting level adjustment and monitoring the audio signal. If an
Audio Processor 2–4 is not delegated to MMCP control, it is independent
of the other APs and is not affected by any MMCP actions directed to video
or other audio processors. It can be slaved to follow AP 1 if desired.
The Audio Processor Delegation buttons (AP 2, AP 3, AP 4) delegate an AP to
MMCP control, delegate level adjust, and delegate monitoring. If an Audio
Processor 2–4 is not delegated to MCP control, it acts independently and is
not affected by any MCP actions directed to video or other audio proces-
sors.
There are two delegation states associated with the AP 2–4 buttons:
■ Low tally, and
■ High tally.
Low Tally Mode
In Low Tally (slave) mode the Audio Processor is crosspoint selection and
transition controlled in the same way as is the primary audio processor
AP 1 (that is, slaved to AP 1 control).
Low tally is toggle–selected. Pushing and releasing an AP 2–4 button alter-
nately toggles it low tally and off, except in the case where, while the button
is high tally, a selection or adjustment is made as described in this section.
In low tally (slave) state, the selected Audio Processor is slaved to AP 1 con-
trol. The slaved AP(s) will follow the modifications made to AP 1 listed
below:
■ Crosspoint selections,
■ Transition control,
■ PGM/PST Level potentiometer adjustments (if so PGM and PST Trim/
Levels are enabled in Configuration Manager, and
■ Output meter and monitor drive signals.
High Tally Mode
In High Tally mode the buttons, selections, adjustments, and monitoring
selections of the MCP are delegated to the indicated Audio Processor only.
