Types of PAS

There are typically two complete PA systems: the "main" system and the "monitor" system. Each system consists of microphones, a mixing board, sound processing equipment, amplifiers, and speakers.

The "main" system provides the amplified sound for the audience, will typically use a number of powerful amplifiers(1000-2000 watts), heavy-duty loudspeakers including low-frequency speaker cabinets called subwoofers.

The "monitor" system amplifies (500-1000 watts) the sounds of the performance and directs them towards the stage performers typically using wedge-shaped monitor speaker cabinets, to help them to hear the instruments and vocals.
