Live Sound & Stage
Live sounds are mostly played to an audience in a closed or open-air venue, and controlled by a mixing console on stage. It is enhanced and amplified through a combination of amplifiers, loudspeakers and signal processors.
Sound Reinforcement Systems (SR Systems) are used and operated by audio engineers at large events and stadiums which involve hundreds of microphones, amplifiers and loud speakers.
Public Address Systems (PA Systems) usually involves one or two microphones and a loud speaker for a smaller audience.
