PA is the acronym of Public Address, that is, sound amplification and diffusion systems intended for the public, but also of Public Announcement, which also includes all the activities and professions directly connected to the production and diffusion of sound, always for the public. Installation PA systems include loudspeakers, built-in speakers (ceiling or wall), PA amplifiers, installation mixers, gooseneck paging microphones for conference use, boardrooms, etc. and also in the safety sector (evacuation systems - EN54-16 regulation).
In most cases, 70/100 V amplifiers and loudspeakers are used, which are easier to manage and install and commonly used in airports, shopping centers, schools, churches, clubs, offices, car parks, sports fields and wherever many speakers are needed to music or voice spread.
