Comparing to traditional PA system, DSPPA IP network system is more flexible and can transmit farther. It is based on DSPPA protocol and compatible with TCP/IP protocol. It takes the advantage of the existing LAN/WAN ,which can help speed up the construction, save cable laying, and combine different networks together.
Different from the previous project, Shenzhen metro system adopted 75 pics of DSPPA phased array column speaker, which is a popular product both at home and abroad.
