The digital multi-address public broadcasting system is an addressable broadcasting system with multiple background music channels and one emergency channel as the sound source input, dual network cable digital transmission, and centralized control. The system adopts an open architecture, replacing the traditional analog signal transmission method, with a compact structure and flexible combination, strong scalability, stability, reliability, energy saving and environmental protection.
1. The system uses a bus-type wiring structure, which is simple and convenient and not limited by the wiring structure;
2. Each host can control 1,000 partitions and can be expanded to more partitions;
3. Different programs can be provided for different partitions, and the partition planning and challenges do not require line adjustment;
4. It can provide arbitrary timed playback function for partitions, and the user can arbitrarily set the selected program time and the required broadcast partition;
5. Each broadcast partition can order programs and adjust the volume at will;
6. The broadcast room can monitor the broadcast status of all partitions;
7. Fire alarm, telephone conference and other functions can be composed through external interfaces and equipment;
8. It can promptly remind the decoding terminal of real-time increase and decrease;
9. The data of all system equipment is transmitted by Category 5 cables.
1. It can be used online with digital multi-address control amplifier to synchronously control up to 1,000 partitions, and the partitions can be named and grouped as needed;
2. It is equipped with a touch screen and touchpad, and can be connected to an external mouse and keyboard;
3. The program playback mode is redundant and flexibly allocated;
4. Real-time partition audio detection is visual and audible, and the operating status of the system terminal is monitored in real time;
5. It can be controlled manually, programmed, PC remotely, and in multiple modes;
6. It has a built-in large-capacity program library and high-quality recording sampling;
7. Partition opening and closing/external power on and off, partition program allocation, external audio source playback and other functions;
8. The timing control plan can be edited, and multiple plans can be preset to call, so that manual instructions have priority;
9. It has intelligent linkage alarm and telephone remote paging function;
10. It can realize Internet control through the local area network, synchronize with the remote PC, and has a work diary record library function.
