Public Address System solution

Public Address System

The Public Address (PA) systems consist of a microphone, a modestly-powered mixer-amplifier (which incorporates a mixer and an amplifier in a single cabinet) and one or more loudspeakers. PA systems of this type, often providing 60 to 240 watts of power, are often used in small venues such as school auditoriums, churches, hotel, restaurants and bars. Public Address systems typically consist of input sources, pre-amplifiers and/or signal routers, amplifiers, control and monitoring equipment, and loudspeakers. Input sources refer to the microphones and CD Players that provide a sound input for the system. These input sources are fed into the pre-amplifiers and signal routers that determine the zones that the 'audio signal' is fed to. The pre-amplified signals are then passed into the amplifiers. Control equipment monitors the amplifiers and speaker lines for faults before it reaches the loudspeakers.
