Application effect:
1. The control center of public broadcasting is set up in the fire control room/broadcasting room, and the IP network broadcasting system server is set up in the control center. The system server is the core equipment, which mainly controls the broadcasting paging and background music playing of the whole system. Provide high-quality background music, including CD player, tuner, PC player, etc, through the control software for file playback, temporary broadcast, set up timing broadcast, the establishment of music library, set up daily background music playback and other functions, the software uses a password login to ensure system security.
2. Auxiliary equipment of the control center: the computer room is equipped with a network broadcast addressing wall-mounted sound box, which is used as the monitoring sound box of the computer room. 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.
