Several Points for Attention in Designing Digital Public Address System

(1) We should understand the needs of users and avoid wasting investment by using network digital broadcasting for digitalization.
(2) Understanding the design parameters of the network system to be built, judging whether the CobraNet network with high-quality guarantee is a convenient and low-cost TCP/IP network, and determining the multicast protocol to be opened, etc.
(3) According to the project situation, priority should be set according to the needs and flexible networking.

Digital public address system is mainly used in stadiums, stations, parks, art squares, music fountains and so on. Its characteristics are large service area and wide space. The background noise is large; the sound transmission is mainly direct sound; the required sound pressure level is high. If there are reflective objects such as high buildings around, the layout of loudspeakers is not reasonable, and the sound wave is reflected repeatedly to form a delay of more than 50 ms. It will cause double or multiple sound, digital public address system, and serious problems such as echo will occur, which will affect the clarity of sound and sound image positioning. The sound effect of outdoor system is also affected by climate conditions, wind direction and environmental interference.
