What is a Public Address System?

A public address system is one that allows a single user or group of users to address a larger public number of people with the use of a microphone (or other audio source), a mixer, amplifier and loudspeakers typically in a venue or building. The components of a public address system are different depending upon the size and type of venue or building and the number of people a system needs to address. Sound Directions are experts in this sometimes challenging area and and design, supply and support public address systems.

What is a Sound Reinforcement System?

Sound Reinforcement (much like a public address system) is the art of using an audio system to enable an audience (of one or more) to listen to a speech or musical performance (which may be live or pre-recorded) with clarity, that they may not otherwise be able to hear due to physical (building or other) or people (large numbers) constraints. A well designed sound reinforcement system should deliver a constant sound pressure level (SPL) over the entire listening area as well as a constant frequency response. This should be achieved by ensuring sound signals are delivered in proper directivity patterns using point source or line array loudspeakers accurately aligned and positioned to ensure phase interferences between each are kept to a minimum. Sound Directions are experts in sound reinforcement systems for any size venue including stadia, concert halls, theatres and public buildings.

What is a Voice Alarm System?

A voice alarm system (sometimes referred to as a voice evacuation system) is very similar to a public address system but it is installed with the safety of staff or general public in mind. It is a system that assists in the effective evacuation of an area or building during a fire, bomb alert or other emergency. Research has proven that in an emergency people will react without confusion or panic if they receive a clear, intelligible message. These messages are stored within a voice alarm system voice alarm system has to work when needed – during an emergency – and is, therefore, fully monitored at all times. It is also backed up by batteries which are fully charged and checked constantly; this will ensure that, even during a mains power failure, the system will continue to operate. Sound Directions are experts in voice alarm system and can design, supply and support voice alarm systems.
