45.3 Zone Grouping
45.3.1 Introduction
On the Zone grouping page, zone groups can be built. A
zone group is a group of zones that, for example, go to
the same geographical area.
For example, Consider a small airport with four zones:
Departure 1, Departure 2, Arrival 1 and Arrival 2. The
zones Departure 1 and Departure 2 contain loudspeaker
lines that go to departure hall 1 and departure hall 2
respectively. The zones Arrival 1 and Arrival 2 contain
loudspeaker lines that go to arrival hall 1 and arrival
hall 2 respectively.
Then, a zone group can be created called Departure Halls
to group the zones that go to the departure halls and a
zone group called Arrival Halls to group the zones that
go to the arrival halls.
45.3.2 Overview
The Zone grouping page (see figure 45.9) contains the
following:
• Name - Shows the name of the zone group.
• Available zones - Shows the available audio
zones. Zones can be created at the Zone configuration
page (see section 45.2).
• Assigned zones - Shows the zones that have been
assigned to the zone group shown in (1)
• Add/Remove buttons - Using the > and <
buttons, selected zones can be added to or removed
from Assigned zones.
• Add - Using this button a new zone group can be
added to the system.
• Delete - Using this button an existing zone group
can be deleted from the system.
• Submit - Using this button changes are submitted to
the network controller.
• Rename - Using this button an existing zone group
can be renamed. Automatically this name is replaced
everywhere in the configuration where this zone
group is used.
45.3.3 Add a zone group
The procedure for creating a zone group is similar to the
procedure for creating a zone (see section 45.2.3).
45.3.4 Delete a zone group
The procedure for deleting a zone group is similar to the
procedure for deleting a zone (see section 45.2.5).
45.3.5 Rename a zone group
The procedure for renaming a zone group is similar to
the procedure for renaming a zone (see section 45.2.6).
45.4 Sparing
45.4.1 Introduction
The sparing function is used to automatically replace
defective main amplifiers with a spare amplifiers when it
is useful. A spare amplifier replaces a complete main
amplifier, even if the main power amplifier is a
multi-channel unit and only one channel is defect. A
spare amplifier can be connected to more than one
main amplifier. However, only the first defective main
amplifier will be replaced by the spare amplifier.

amplifiers.
