Public Address Systems
Audio Visual Machines offer Public Address Systems installation for commercial applications. Dedicated to provide better sound through the use of leading edge technology and good design. We are one of the leading specialists in PA Systems installation in the United Kingdom. Our engineers have years of experience designing and installing PA systems. We can offer advice and consultation on Public Address equipment and systems.
Specialist PA systems are available to suit any application, such as a church pa systems.
We have designed public address systems to corporate headquarter buildings, churches, piers, stations, meeting halls, conference rooms, schools. Audio Visual Machines can supply suitable equipment for your application. We offer a full service, from design, to supply and installation. Controls for the public address amplifier can be placed in convenient places. Systems are designed to suit your premises and can be multi-zone if required.
How long does it take to install the system?
Public Address Systems vary in size and complexity. We will attempt to minimize how long it takes to install your system without compromising quality. Sound quality is of utmost importance. Our systems use the optimal number of speakers and speaker location to suit your environment. Using leading brands we are able to achieve high quality audio.
Can we install Induction Loops with our systems?
Yes we can. We offer a full service. Our systems are fully upgradable. Please see our page on induction loops systems.
Achieving Sound Intelligibility
The main reason for a sound system being rendered unintelligible (assuming it is loud enough) is the deleterious effect of the acoustics of the building. Certain frequencies are naturally emphasized, others suppressed, leading to a significant loss of audio information. This, coupled with reverberation and echo can render even a loud sound unintelligible - think of a bright, but out of focus picture.
A well designed system can overcome the problems by specifying the correct equipment: microphones specifically suited to speech, equalizers which can be set to compensate for non-linear acoustics, and an even distribution of speakers at carefully chosen locations to minimize echo and delay effects.
A further problem can be achieving a sufficient level of amplification in the sound system before the onset of howling "feedback". This can be overcome by careful choice of microphones, siting of speakers and, in extreme cases, by the use of a dedicated digital processor to specifically detect the onset of feedback and instantly apply preventative measures - automatically.
