SITA Public Address System | SITA



SITA Public Address System is a public address system (PA) and media management solution, designed specifically for the air transport industry (ATI). It combines audio communications with real-time visual updates. So, whenever an announcement is made over the PA, a corresponding message automatically appears on video screens across the airport.

By employing the very latest audiovisual technology, SITA Public Address System ensures passengers are kept informed at every stage of their journey through the airport. It can help you improve operational efficiencies, make better use of staff resources and enhance the passenger experience.

It can also help you grow ancillary revenue through targeted audiovisual advertising.
