Applications

Adastra products cover environments and applications with a focus on clear and ecient sound coverage.

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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 dierent 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 ecient speech delivery and wide area coverage.

Typical venues include: schools/universities, medical centres,

market halls, airports, train stations and places of worship.

Public Address Systems

Generally, background music is a term used for pleasant

and unobtrusive playback of recorded material. Many public

buildings bene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 dierence is that full range audio quality is

imperative with background music in order to make it

listenable and inoensive, which is not necessarily a key

requirement for basic speech delivery.

Applications include: bars, retail outlets, restaurants,

galleries, museums and leisure centres.

Background Music 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ers

are more often sited in an indoor environment.

Typical environments include: patios, auction sites, arenas,

theme parks, marinas and swimming pools.
