Today, with the rapid development of science and technology and society, people have more and more information in their daily life and work. Therefore, information exchange and communication between people become more and more frequent and important. The digital age has been integrated into our personal and professional lives. Audio is no exception, all this will not go backwards. As mentioned above, the market demand for digital wireless microphone is beyond doubt.
After 20 years of dedicated research and development of wireless microphone, Diesp has developed a series of digital wireless microphone products in recent years, including digital wireless microphone module, digital wireless instrument microphone, digital wireless conference microphone, and so on. Our products have attracted the attention of our peers and won the favor of many customers!
1. What is a digital wireless microphone?
Digital wireless microphone, as its name implies, is a microphone and electro-acoustic device that directly outputs digital pulse signals. Digital wireless microphone system is composed of computer, digital and network technology. The transmission of digital signals on the line not only greatly improves the sound quality and reliability of the system, but also fundamentally eliminates the defects of interference, distortion, serial frequency and system instability in general wireless microphone system. It makes the receiving of digital wireless microphone more stable and the sound purer.
2. Principle of Digital Wireless Microphone
The principle of digital wireless microphone is basically formed by "transmitting" and "receiving".
Transmitted mainly through analog signal to digital, and then after encoding processing, then to analog signal, then through modulation, and finally through power amplification to send out.
And the receiving link is slightly more complicated than that. It mainly receives through antenna, then amplifies the low noise, and proposes analog audio signal through mixing. Then it transforms analog signal into digital signal to increase the signal. After filtering the high frequency noise, it converts the digital signal into analog audio signal after decoding, and finally outputs it.
Therefore, compared with traditional wireless microphones, digital wireless microphones will have higher signal-to-noise ratio, wider audio frequency response, higher fidelity and strong confidentiality.
