The wireless public broadcasting system is a broadcasting system that transmits signals by wireless transmission. It uses the most advanced dual-lock screen subcarrier coding remote control technology, with accurate frequency, and can achieve point-to-point remote control. Because it does not require poles and wires, has a wide coverage range, unlimited expansion, easy installation and maintenance, low investment, and beautiful and clear sound quality, it is widely used in campuses, parks, scenic spots, factories, enterprises, and remote mountain villages. It has irreplaceable advantages in the transmission of audio signals in the last mile.
1. The signal is transmitted by wireless transmission, without wiring, avoiding the loss of high and low frequencies in the line, and the sound is beautiful, clear and full;
2. Support unlimited expansion. It can be expanded wirelessly within the coverage of wireless FM signal, which completely solves the problem of difficult expansion of wired broadcasting;
3. Use coding remote control to realize point-to-point remote control of host and terminal;
4. Microcomputer phase locking is adopted, the transmitting frequency does not drift, and the performance is stable and reliable;
5. The wireless signal has been strictly encrypted and decrypted, and external signals with the same frequency cannot open the device, making the system safe and reliable;
1. It adopts ARM control core, DSP radio chip, diversified integration, integrated timer, MP3 player, coordinator, monitoring, alarm and MIC microphone functions, with the characteristics of simplicity, practicality, stability, efficiency, energy saving and environmental protection;
2. 7-inch industrial-grade high-definition LED touch screen, supporting 1024*600 resolution;
3. Dual network ports with data and broadcast optoelectronic standards for management and data output;
4. Comes with 3W monitoring speaker;
5. The system supports USB playback and partition management, supports event recording, and retains operation logs and corresponding recording files;
6. It has frequency memory storage function and automatic recovery function when broadcast power is off;
7. Have fixed telephone, mobile phone and network receiving module;
8. With manual one-button alarm function;
9. Each controller has a unique address, which is more secure;
10. Automatically identify incoming call numbers from communication tools and only develop control over pre-set authorized calls;
11. You can remotely force the broadcast room equipment to open by phone (landline, mobile phone), issue warning voice messages and alarm messages, and automatically maximize the output of equipment strategies when issuing;
12. It has a timing function, which can manually preset the timing, location and program of daily broadcast programs to achieve unattended and automatic playback.
