Digital K Song Scheme-Microphone And The Professional Match Between The Projector

Microphone: Energy converter of sound signals, equipment for electrical signal conversion

The microphone, the scientific name is the energy conversion device that converts the sound signal into a electrical signal, also known as a microphone or microphone.It mainly includes pickup noodles and signal amplifier circuits.This electric energy replacement made of micro -machine processing technology has the characteristics of small volume, good frequency response characteristics, low noise, high integration, and suitable for large -scale production.

Microphone module: an excellent choice to improve performance and convenience

The microphone module is composed of microphone and microphone circuits. Among them, the microphone circuit can add electrical connection power modules, filter modules, signal processing modules and signal output modules according to customer requirements.With the development of science and technology, wireless microphones have been widely used in various scenarios, such as activities, conference scenes, KTV rooms, home theater, live broadcast, interviews, etc.

Optimize system performance and improve the performance of microphone modules

In order to reduce the difference in performance generated by microphone units to the system and reduce the performance requirements for microphone units, the microphone module solution provided by Gongci.com has great advantages in terms of system volume, cost, power consumption, and anti -interference.

Advanced Technology: Intelligent noise reduction and dynamic gain algorithm

The solution uses intelligent noise reduction and dynamic gain algorithms.When a microphone is used, the noise reduction mode of the two microphones can be automatically aligned. The three modes of high -end, strong noise reduction, and weak noise reduction can be freely switched.In addition, it also has a full digital IIS output audio format with a low -delay stable transmission and high -fidelity sampling rate.Whether it is indoor or outdoor, it can achieve clear pickup.
