How do wireless microphones work?

　　The performance of the Wireless microphone is often affected by the interference of the frequency of peripheral equipment, improper operation by users and other factors and a variety of failures, the next, Xiaobian will teach you how to avoid and prevent the most common Wireless microphone problem.
　　There is a different degree of compatibility between frequencies, and if you are well aware of your system's condition, you can use more systems more aggressively, but the point is how to weigh the compatibility of your entire system.
　　Most frequency-compatible software have an important assumption at design time that all receivers are always on or not mute (even if some transmitters are turned off occasionally) so that all receivers do not pick up To the possible noise intermodulation signal.
　　When the transmitter is located very close to the receiving antenna, or high-power transmitter is running, the interference will be more serious. That's why it is far more difficult to have 40 wireless Microphone systems in a movie theater than to work in schools (many transmitters are very close to the receiver), and there is a system in every classroom in the school, complete with transmitters Independent, but close to their own receiver.

　　BY-WM8 Dual Channel UHF Wireless Microphone System
　　The BOYA BY-WM8 Dual-Channel UHF wireless system is a portable, camera-mountable wireless system for capturing audio with dual subjects. It can be used in several environments for video, field recording, interview, broadcast TV, and ENG applications.

　　It features an easy to read LCD display, a wide switching RF bandwidth, a Mic/Line switchable input, and digital circuitry, rugged lightweight plastic housing.

Workaround: To balance the larger number of system devices with high performance, make sure that the compatibility level between frequencies is appropriate for the intended system. Keep the transmitter to receive antenna at least 10 feet away from each other and use a lower transmit power to cover the expected distance between transmitter and receiver if the transmitter's RF output power is adjustable.
　　When using wireless microphone systems, 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.

Using a Shotgun Microphone for Video Interviewing

　　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

What are the best budget wireless microphones for Smartphone ？

　　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 Best Wireless Microphone and System in 2018

　　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
