Auditorium and PA systems

What are Auditorium and PA systems?

Auditorium and PA systems allow speech and sound to be amplified beyond the levels of sound a human can naturally produce.

In its most simple form a PA system will include a microphone, a power amplifier, a mixer and speakers. 

The microphone is used to detect the sound; this sound is then passed through the mixer to stabilise and improve the sound quality. The mixer will then send the sound signal to the amplifier which powers up the signal that the speakers will play. 

Depending on the use case for the Auditorium and PA system the number of speakers and microphones will vary, also there could be additional devices that ensure that audio is being transmitted and processed properly. For example, a live music event featuring acoustic instruments will feature different speakers for the vocals (to produce mainly high tones) and dedicated subwoofers (to produce lower tones). Most modern live events will also combine the PA system with some form of Video Wall or AV screen to provide a visual experience to the event.
