4.2.1 Volume adjustment <Volume>
The volume of the inputs and output amplifier (master) can be adjusted in this menu.
The adjustment range of the inputs is -100dB to + 10dB. The amplification range is
-100dB to 0dB
The general volume can also be adjusted using the up and down buttons directly from
the main screen.
4.2.2 Matriz <Matrix>
The Matrix menu manages PA sources and their routing to zones.
In each zone, we select the priority sources that are allowed, then their trigger will
activate the source in that zone.
The music source is selected and activated always, it is called BGM in the display. It is
possible to select Input 3, Internal mixer or none.
Example: ZONE 1
In 1: Yes
In 2: Yes
BGM: < In3 | In4Mix | None >
The active source in this case by default is source #3, since sources 1 and 2 will be
waiting for the activation of their trigger.
If several inputs are activated at same time they will be automatically selected by the
system following their priority level.
In this case Higher priority of these inputs is input 1 followed by input 2, internal
mixer(In4Mix) and then input 3.
Remember that other sources have higher priority levels, ACSI microphones, alert
message, evacuation message and fireman microphones are higher. Any of these inputs
will override the PA inputs when selected from same zone.
