TECHNICAL DATA | TYPES OF SYSTEM | ZONING SYSTEMS
Zoning Systems
A zone can be a room or a group of rooms. Equally, a zone could
be part of a room or even an outside space. Essentially, wherever
separate control over the ampli昀椀ed sound is needed would be
considered as a separate zone.
Sound systems are often installed in public spaces to deliver
spoken word, music and other audible information to listeners in
many different environments.
Zoning systems are 昀氀exible sound systems that provide control
for the sound that is delivered to different areas, called 'zones'.
In the example diagram shown,
a building has been separated
into 5 zones.

4 The rest room has its own Zone 4, so that audio from a TV
can be ampli昀椀ed to the room, whilst still receiving emergency
alerts along with paging alerts to send voice messages
to the room.
1 Public areas, such as reception, corridor and W.C. are served
by Zone 1 output to receive the same background music along
with voice paging alerts.
2 All of昀椀ces are served by Zone 2 because they never require
background music and only ever need the emergency alerts
that are broadcast to all zones.
5 Finally, Zone 5 is the 昀椀re assembly area at the rear of the
building, which requires emergency and paging alerts in case
of 昀椀re or other emergency drills.
3 The meeting room has its own independent Zone 3, as it
needs audio from a laptop to be ampli昀椀ed to the room for
presentations and video conferences. Emergency alerts are
also active in this zone.

POWER
To add individual control over the volume in each zone, it is possible to use individual volume controls. The Adastra RM244V has 4
built-in attenuators to enable control of the output volume to 4 separate 100V outputs. Again, the sound produced at each zone will
be the same but the output level of each can be adjusted.
Adastra RZ45 - 953.045UK
For total 昀氀exibility, the Adastra RZ45 is a 5 zone audio matrix with source and output volume fully controllable via touch-operated
wall plates, which can be located within each relevant zone or elsewhere.
Any of the 5 zones can be fed from 3 selectable audio sources or the internal media player and the level of each is independently
adjustable. Overall emergency paging to all zones is provided by a paging mic input and an optional call station can address
individual zones for voice messaging as needed. Again, the output can feed an Adastra RS605 or 5 separate ampli昀椀ers or even
active speakers in each zone.
