45.1Introduction

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).

45.2.1 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.

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).

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

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.
