The term is also used for systems which may additionally have a mixing console, and amplifiers and loudspeakers suitable for music as well as speech that can be used to reinforce a sound source, such as recorded music or a person giving a speech or distributing the sound throughout a venue or building.

Public address systems are ideal for evacuating the general public in a safe and orderly manner in case of emergencies or alerts. Clear transmission of messages can also be broadcast for live announcements and even background music to either the whole building or pre-determined areas (zones).
