DSPPA IP network PA system applied in Shenzhen subway transportation system, covering the metro depot of line 9, line 11 and parking lot, which are going to be opened on June , November of the year 2016 respectively. This project contains 4 sets of IP network PA systems and more than 70 phased array column speaker.
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.
