On the Zone options page, zones can be created. A zone is a group of audio outputs that, for
example, go to the same geographical area.
Configuration example
As an example, amplifiers that are part of a PRAESENSA system on an airport:
–
Audio outputs of amplifier 1 and amplifier 2 go to departure hall 1.
– Audio outputs of amplifier 1 and amplifier 2 go to departure hall 2
Then, a zone can be created called Departure 1 to group the loudspeaker lines that go to
departure hall 1 and a zone called Departure 2 to group the loudspeaker lines that go to
departure hall 2.
–
Notice that an audio output cannot be part of more than one zone. After an audio output
has been assigned to a zone, it is not allowed to assign the audio output to another zone.
