Why choose a digital wireless microphone system?


The digital age has been integrated into our personal and professional lives. Audio is no exception, and digital wireless microphones are increasingly demanding the market through their own capabilities. Why are more and more people choosing digital wireless microphones?

What is a digital wireless microphone?

Digital wireless microphones, as the name implies, are microphone electro-acoustic devices that directly output digital pulse signals. The digital wireless microphone system uses computer, digital and network technologies to network each system. The digital signals transmitted on the lines are not only greatly improved the sound quality, but also improve the system reliability.

Moreover, the defects such as interference, distortion, crosstalk and system instability existing in the general wireless microphone system are fundamentally eliminated. Make digital wireless microphone reception more stable and sound more pure.

How digital wireless microphones work?

The principle of a digital wireless microphone is generally formed by "transmitting" and "receiving".

The transmission is mainly converted into digital by simulation signal, and then encoded, converted into an simulation signal, and then modulated, and finally transmitted through power amplification.

The receiving session is a bit more complicated than it is.
Mainly through the antenna, then zoom in on low noise. Propose an simulation audio signal by mixing, then the simulation signal is converted to a digital signal to emphasize the signal. After the high-frequency noise is filtered out, the digital signal is decoded and the digital signal is re-converted into an simulation audio signal, and finally output.

Therefore, compared with the traditional wireless microphone, the digital wireless microphone will have a higher signal to noise ratio, the audio frequency response will be wider, the fidelity is higher, and the confidentiality is also strong.


What are the advantages of digital wireless microphones?

1.Outstanding sound quality


The digital wireless microphone system delivers high quality, clear and bright audio. This is largely because traditional wireless microphones do not have a "compression expander", a circuit that reduces noise and maximizes dynamic range for all simulation wireless microphone systems. The audio signal is first compressed by the transmitter to accommodate the limited dynamic range of the FM transmission and then spread in the receiver.

The process of compression and expansion, although relatively small in most good simulation systems, there are some artificially audible sounds that would make the sound of a wireless microphone slightly different from that of a wired microphone. With digital wireless microphones, the transmission of audio signals no longer requires compression and expansion, and the received signals restore the precise characteristics of the original audio.

The process of compression and expansion, even if the impact in some high-quality simulation systems is very small, there will be some artificial, audible sound, which makes the difference between the sound of the wireless microphone and the sound of the wired microphone.With digital wireless microphones, the transmission of audio signals no longer requires compression and expansion, and the received signals restore the precise characteristics of the original audio.

2. Longer battery life


In general, digital wireless microphone systems have a 30%-40% longer battery life than the same simulation system.

3.Compressor (variable)

A digital wireless microphone system that achieves the entire audio range with a flat frequency response curve.
The digital wireless microphone converts the simulation audio into a digital signal by modulating the radio carrier in several steps. The digital audio signal arrives at the receiver without being affected by electromagnetic noise. Any RF noise below the threshold will not affect the audio quality. The receiver simply ignores anything that is not 1 or 0. All others are ignored. Only digital signals can be identified.

4.Excellent spectral efficiency

By allowing tighter channel spacing, digital wireless microphone systems can use more effective compatible frequencies simultaneously in a certain frequency band. This feature is especially important. Typically, a digital wireless microphone system can deliver twice the frequency of use compared to the same simulation system wireless system.

The advantage of a digital wireless microphone is the reason we choose it. Digital wireless microphones have changed the traditional wireless microphone and brought profound changes. It is believed that with the further development and integration of modern communication technology and computer technology, it will penetrate into various fields of social life and play an increasingly important role.
