Public Address Systems

VSI offers advice to the Public Address System, which comprising microphones, amplifiers, loudspeakers, and related equipment. It is mainly being used in any public venue that requires that an announcer, performer, etc. be sufficiently audible at a distance or over a large area. Typical applications include sports stadiums, public transportation vehicles and facilities, and live or recorded music venues and events. A PA system may include multiple microphones or other sound sources, a mixing console to combine and modify multiple sources, and multiple amplifiers and loudspeakers for louder volume or wider distribution.

Analog and Digital IP based PA Systems are available , for venues such as airport, control room, station, and school auditoriums etc. PA systems with many speakers are widely used to make announcements in public, institutional and commercial buildings and locations – such as schools, stadiums, and passenger vessels and aircraft. Intercom systems, installed in many buildings, have both speakers throughout a building, and microphones in many rooms so occupants can respond to announcements. PA and Intercom systems are commonly used as part of an emergency communication system.
