Applications
Adastra products cover environments and applications with a focus on clear and ef昀椀cient sound coverage.
Public Address Systems
A public address system is a means of sound reinforcement
for relating speech and audible information to a group of
people. The setup may vary from a single portable ampli昀椀er
in a small room to an intricate multi-room zoned system
with multiple speaker arrays.
Since each public address venue will have its own
characteristics, there are many different speaker types
and installation methods depending upon the architecture
of the building, ambient noise levels and coverage
requirements. The key demands from any public speaker
are ef昀椀cient speech delivery and wide area coverage.
Typical venues include: schools/universities,
medical centres, market halls, airports, train stations
and places of worship.
Background Music Systems
Generally, background music is a term used for pleasant
and unobtrusive playback of recorded material.
Many public buildings bene昀椀t from background music
systems to help create an ambience or mood for their
service users. These systems may be tailored to each
building and its function in much the same way as with
public address systems.
The main difference is that full range audio quality is
imperative with background music in order to make it
listenable and inoffensive, which is not necessarily a
key requirement for basic speech delivery.
Applications include: bars, retail outlets, restaurants,
galleries, museums and leisure centres.
Outdoor and weatherproof systems
Some public address and background music components
are designed for use in outdoor or damp environments.
The materials used and construction methods help to
make them weather resistant and able to withstand
outdoor conditions.
The main factors to be taken into account when planning
outdoor or weatherproof systems are safety and durability
of the electrical components to be used within the
proposed environment. This includes any of the equipment
exposed to the potentially damaging elements including
speakers, transformers, cabling and connectors. Mixers and
ampli昀椀ers are more often sited in an indoor environment.
Typical environments include: patios, auction sites, arenas,
theme parks, marinas and swimming pools.
