Audio – public address system
Audio – public address system
A basic public address (PA) audio system is made up of 3 parts:
input sources – where the acoustic sound is transformed into an electrical audio signal
processing devices – where the electrical audio signal is manipulated, mixed, recorded and amplified
output devices – where the electrical audio signal is converted back into acoustic sound waves and transmitted to be heard by humans.
