A public address system (PA system) is an electronic amplification system with a mixer, amplifier and loudspeakers, used to reinforce a sound source, e.g., a person giving a speech, a DJ playing prerecorded music, and distributing the sound throughout a venue or building. PA systems with a larger number of speakers are widely used in institutional and commercial buildings, to read announcements or declare states of emergency. Intercom systems, which are often used in schools, also have microphones in each room so that the occupants can reply to the central office. College campuses, schools, medical centers, office buildings, manufacturing plants, military bases and other facilities, can now easily add, replace or expand their existing Public Address system, by adding wireless speakers and call stations.

GITS offers a variety of wireless speakers for any type of indoor or outdoor application. The speakers can be programmed to be activated individually or as part of a group (zone).
