45.2.1 Introduction
On the Zone configuration page, zones can be built. A
zone is a group of audio outputs that, for example, go to
the same geographical area. For example, consider
multi-channel interfaces PRS-MCI with basic amplifiers
that are part of a Praesideo system on an airport:

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.
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.
To control external devices during the audio phase of a
call, it is possible to include Zone active output and Volume
override output control outputs in a zone. A Zone active
output control outputs is activated when a call starts and
deactivated when a call ends in the zone of which it is
part. A Volume override output control output performs the
same action for calls with priority 32 or higher.
