ESCRIPTION
There are three input sources that can bypass all signal processing
devices, in the event of failure, to perform a broadcast to all zone
outputs.
Inputs 1 and 2, usually reserved for fire microphones, when
accessed route their signals directly to all outputs via non volatile
volume controls.
Under normal non fault conditions the evacuate message is stored
in flash memory and is accessed by its associated DSP, however in
the event of DSP failure a separate non processor derived fail-safe
message will be broadcast to all zones.
All three of these inputs have independent level controls and the
overall output level is set using a master control.
If zoning is required on input 1 or input 2 they will automatically
be routed via the DSP using input 7 and 8 respectfully.
In the bypass mode these three inputs have a fixed priority level
where input 1 is the highest and the emergency message is the
lowest.
