Security Innovation is a company that specializes in public address and Evacuation systems. Public address system is an electronic system that includes microphones, amplifiers, amplifiers and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, other sound source, or a recorded sound or music. In any public place, the broadcaster, performer, etc. must be heard enough over a distance or over a large area. Typical applications include sports fields, vehicles, public transportation facilities, and live or recorded music venues and events. The system may include multiple microphones or other audio sources, a merge controller and multiple source editing, multiple speakers and amplifiers of a higher size or wider distribution.
These simple systems are often used in small places such as school halls, churches, and small bars. It is also widely used for speakers to issue advertisements on buildings, public, institutional, and commercial sites-such as schools, stadiums, passenger ships, and aircraft. Intercom systems , installed in many buildings, have amplifiers throughout the building, and microphones in many rooms so that passengers can respond to ads. These systems are commonly used as part of the emergency communications system.
