Overview of Fanvil PA3
The Fanvil PA3 is a SIP public announcement gateway designed to fit inside any installation, especially for public broadcasting. Using standard IP/RTP/RTSP protocols, it delivers HD audio for real-time and scheduled MP3 broadcasting and one-touch intercom when connected to external buttons, microphones and speakers. A mono amplifier up to 30W drives passive speakers directly, while line-out expands to active speakers, and the USB 2.0 port and TF card slot enable local storage and offline broadcasting. With 2 SIP lines, PoE Class 4 and web management, the PA3 is ideal for building custom broadcasting solutions for campuses, shopping malls, railway stations and buildings.
