Through the control of the server software, the monitoring sound box can be used to monitor the program playing content and playing volume of each area in the front end. As the auxiliary audio source equipment of the system, the preamplifier integrates the audio sources of digital players and digital radios, and can play to each partition or all broadcasting areas through the acquisition and broadcasting of broadcasting software. In addition, a broadcasting microphone is configured for emergency broadcasting and broadcasting speech in emergency situations. In addition, a fire-fighting interface unit is installed to facilitate the access of fire-fighting signals and can be forced to switch to the fire-fighting emergency broadcasting state in emergency situations, the fire alarm of any area can be set at will to realize the fire linkage. As a power supply sequencer for system auxiliary equipment, the power supply can be turned on or off sequentially to protect the equipment.
3. Install a color screen touch broadcasting system paging microphone in the control center, which can page and broadcast each area. The broadcasting mode can be broadcast in a single area or multiple areas.
4. Set up a broadcasting system cabinet-type decoding terminal and a power amplifier in each area to be responsible for the broadcasting of programs in the area. The broadcasting system cabinet-type decoding terminal in each area mainly decodes and plays the control signal and audio signal from the main control server in real time, converts the digital audio signal into an analog audio signal, transmits it to the power amplifier, and finally transmits it to the front-end speaker for playback by the speaker; at the same time, it has the power amplifier power management function and local broadcasting function, which can ensure that when the power amplifier does not work, it can automatically stop power supply and prolong the service life of the power amplifier. The cabinet-type decoding terminal of the broadcasting system itself does not have a power amplifier and needs to be connected to the power amplifier.
5. According to different functional requirements, the design of each floor is divided into different areas, mainly divided into room area, corridor public area and lobby area. Each area is equipped with a certain number of ceiling loudspeakers to be responsible for the background music broadcasting system of the area.
