PA System

The Technology behind a PA System

21/5/2020

Hosting a large event? Need to be heard? More likely than not you require a Public Address System or more commonly referred to as the PA system. Once exclusive to bands, DJs and sound engineers, today’s PA systems are much more available and at a greater variety to meet different applications. Whether it’s for a small scale event like a conference, or a concert, definitely let us know and we will be able to advise accordingly!

What is it? 

A public address system (PA system) is an electronic system that comes with microphones, amplifiers, loudspeakers, and related equipment. It enhances and increases the apparent volume and clarity of a human voice, musical instrument, or other acoustic sound source or recorded sound or music.

How do PA Systems Work?

The main purpose of a PA system is to provide “public address”, or a way to transmit audio communication to a certain group. This transmission can begin with a microphone, which is a device that can assist in magnifying an audio source’s volume. Microphones used in PA systems are usually dynamic or condensers.

There are five main parts to any PA system:

  • Microphones, DI boxes and other sources.
  • A mixer.
  • Power amplifiers.
  • Speakers.
  • An arrangement of cables to interconnect the equipment.

If you’re new to PA systems, here are some of the main specifications to consider!

  1. Wattage
    This describes the volume potential and speaker clarity. Generally, the higher the wattage, the louder a PA speaker will be able to get. This is important as insufficient wattage would result in fuzzy sounds and constant break ups.
  2. Size and weight
    Inches over diameter is how speakers are measured. As expected, a large speaker would result in a more expansive sound. Weight would be a factor as well, including the type of materials used to house the speaker.
  3. Sound quality
    A musician would more likely be concerned about this specification. They would definitely value clarifty and definition over other professions that purely require a system that allows them to make their voice heard.
