With the passage of time, brands such as Audio-Technica, Sennheiser and Shure gradually entered the domestic high-end sound system.
　　With the development of electronic technology and the growing use of wireless microphone technology, market, applications have made great strides, the price is gradually approachable, all kinds of brands, various types of wireless microphone after another. Especially in recent years, domestic wireless microphone emergently in the middle and low-end market occupy half of the country. Enping Guangdong even appeared in the production of wireless microphone (microphone) distribution center.

　　BY-WM5 Wireless Microphone
　　BOYA BY-WM5 wireless microphone is for use with DSLR cameras, camcorders. The 2.4 GHz GFSK system result in strong anti-interference, good security and stability.
Wireless microphone

　　Relatively speaking, wireless microphone are more expensive than wired microphones, which are more technically complicated and more delicate in use. Therefore, how to select and use a wireless microphone for this article is introduced.
　　The Wireless microphone has gone through about three stages from the very first simpler wireless FM transmitter and wireless FM receiver to the current dedicated PLL (frequency-locked loop) technology.
　　Simple FM transmitter and receiver

　　At that time, in order to get rid of the fetters of the microphone cable, people came up with the principle of transmitting and receiving similar to FM radio. Through the microphone's transduction principle and audio → modulation → amplification → transmitting process, and then through the FM radio or dedicated receiver (special frequency ) Receive, playback. Can be imagined, its sound quality, stability, anti-interference ability, etc. can not meet the actual needs.

　　Stage audio equipment in many different types of audio, microphone (or wireless microphone ) + mixer + amplifier + speakers can be. In addition to the microphone source, sometimes also need DVD, computer music, etc., can also be used computer. But if it is to be a professional stage sound effects, in addition to the professional stage staff, plus effects, timing, equalizer, voltage limiter and other audio equipment. 　　A sound mixing device with multiple channel inputs, the sound of each channel can be processed separately and with left and right channels, mix, monitor, etc. output. Is the sound engineer, sound engineer and composer for music, sound important equipment. 　　The audio voltage signal is converted to a fixed power signal used to drive the speaker sound equipment. Power amplifier matching conditions. 　　 BY-LM400 Dual-Lavalier Microphone 　　The BOYA BY-LM400 is a dual-lavalier microphone is designed for recording interviews. With 3.5mm(1/8") TRRS connector

　　Many people think that choosing a good quality wireless microphone can avoid all kinds of interference. In fact the anti-jamming microphone and the quality of the microphone itself is not much direct contact. Only the correct use of wireless microphone can effectively extend the life of the microphone, to avoid errors caused by: microphone whistling, interference, sound quality distortion and damage to the microphone components. 　　When using a handheld wireless microphone , the distance between the microphone and the mouth is generally maintained at 5-10cm is better, too close to have a near talk effect, too far off the sound, will undermine the sound quality; in the use of lavalier microphone, to prevent Microphone too far away from the mouth, as close as possible to the mouth; use the headband microphone is to avoid the mouth is facing the microphone head, to avoid the impact of vocal airflow should be moved to both sides. 　　With the popularization and widespread use

　　The performance of Wireless Microphone is often affected by various factors such as frequency interference, user error handling, and so on. This article will teach you how to avoid and prevent the most common wireless microphone problems. 　　When using Wireless microphone , there is always interference between the system itself. Although each system has frequencies or intervals of several megahertz, Intermodulation Distortion (IMD) can still cause interference between microphones. If there is not enough space between the intermodulation signal and the device's operating frequency, it is difficult for the receiver to pick up the signal from the transmitter. Typical phenomena are crosstalk between systems, frequent signal loss or excessive noise and distortion. 　　The minimum separation between frequencies depends on the design of the system receiver, which may require an interval of 1 MHz from the nearest neighbor. The more expensive receivers usually have narrower adj
