45 Zone & amplifier
45.1 Introduction
On the Zone & amplifier pages, the zones and amplifiers
can be configured. It is possible to:
• Configure zones (see section 43.2).
• Configure zone groups (see section 45.3).
• Assign spare amplifiers to main amplifiers (see
section 45.4).
• Configure BGM channels (see section 45.5).
45.2 Zone configuration
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:
• Audio outputs (MCI_01_AMP1) and (MCI_01_AMP2)
go to departure hall 1.
• Audio outputs (MCI_02_AMP1) and (MCI_02_AMP2)
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.
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.

Note
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 (group).
Note
A control output cannot be part of more than
one zone. After a control output has been
assigned to a zone, it is not allowed to assign
the control output to another zone.
