1. The system selection is based on the needs of the stadium, and we use the IP network broadcasting system. The imitation stone sound is installed in the lawn area outside the stadium, and the high-power waterproof sound column is installed on the four walls inside the stadium. In addition, wall mounted and ceiling mounted audio systems shall be installed in the office area. The whole venue is divided into six divisions. Each partition is used for music processing by independent terminal decoding power amplifier. Set up three sub-control points at the venue and install wireless microphones to call the whole area. The power amplifier is connected by the way of decoding terminal. There are generally two types of wall-mounted decoding terminal and rack-type decoding terminal. According to the characteristics of the mall, the rack-type decoding terminal is selected. Connect the audio cable with the power amplifier, and then connect the power amplifier with the background music speaker through the RVV cable. The speakers are arranged according to the scope of the project site. If the power is large, the preamplifier+pure post-stage power amplifier mode is used. If the power is small, the combined power amplifier mode is used to complete the peripheral configuration of the whole project.

3. The functions that the stadium can achieve 1) The all-weather background music playing in the public lawn leisure area of the stadium and the regular broadcasting in the parking lot. Playback has multiple playback modes. 2) The fire control system inputs the alarm signal, and the intelligent linkage broadcast server processes the broadcast fire alarm broadcast. 3) Emergency broadcasting is the broadcasting of personnel evacuation in case of emergency. The system can select the broadcast function in the programmed combination area of the microphone, and combine the area to be broadcast at will. 4) Four sub-control points are set up, and the software is installed on any computer. Through the software, the functions such as timing program editing, song setting and storage are performed.
