IP Network PA Overiew
- Functionality: terminals work independently from another (e.g. 300 terminals on the LAN play 300 different programs). It covers all of the functions provided by legacy systems, carries out advances functions such as AOD, communication between terminals, etc.
- Transmission: unlimited transmission distance, as far as the network reaches. It scales in size as the network grows, from the local network to wide area network covers a great distance. The signal can be sent from the central campus/office to every branch campus.
- Quality: the system supports up to CD quality playback. The quality is sufficient for listening comprehension exercises in language examination like university entrance test, CET 4,6, etc. Students can take great advantage of the crystal-clear sound.
- Reliability: redundancy between the audio server (Windows OS) and IP console (embedded OS); should anyone fail, the other one will automatically take over all of the terminals, ensuring the zero downtime and seamless switchover.
