IP PA system

IP intelligent digital pa system is pure digital network audio pa system based on WAN and LAN. its a pa system different from analog audio, frequency modulation, address and digital control pa. IP intelligent digital pa system completely covers the nowaday WAN/LAN, applying TCP/IP agreement, and using the existing school network or internal LAN, no need to dispose line again. inlaidhardwareterminal, could set unique IP address code, by multi-layer permutation, could arbitrary control the program setting and playing of each terminal by mainframe. even could select the program in need by terminal. as this system adopt the computer tech, it almost support all the audio file format. and adopt IP tech, the playing program with no any limite, each terminal could play the program in need arbitary. so this system could completely replace the traditinal intelligent pa system based on analog and digital and realize the IP audio broadcast based on WAN/LAN. this system is easy to install and expand, and the later repairing costs little.
