A power amplifier(53) amplifies sound source necessary for broadcasting which is outputted from the system controller. A sound player(52) conducts data communication with the communications unit. The sound player generates sound source necessary for broadcasting. A control computer(51) configures, manages and monitors the entire public address system.
