Adjust and monitor volume across multiple audio zones and send live audio announcements - all through a fast and intuitive interface. You can also play your own tones and sounds from a tap-to-play sound board, and even record your own tones and messages right in the app. Designed for schools, businesses, and other places that use network audio, paging, or public address (PA) systems.
