wireless microphone

　　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 receiving antenna of the Wireless microphone is one of the most misunderstood. Antenna selection, layout, and cabling errors can result in short distances in the performance coverage area and low signal strength, resulting in frequent dropped calls. Modern diversity receivers deliver far better performance than individual antenna types, but to optimize system performance and reliability, the antenna selection and placement must be correct. 　　If the receiver is to be located far away from the performance area (such as in a device closet or enclosed rack), install a half-wave antenna or a directional antenna remotely, preferably over the viewer, so that there is a clear Line of sight. Do not install ¼ shortwave antennas remotely because they use the receiver chassis as a ground antenna. 　　 BY-WHM8 UHF Wireless Handheld Transmitter 　　The BOYA BY-WHM8 is a Wireless handheld transmitter with a dynamic, cardioid capsule, suitable for BOYA BY-WM6 and BY-WM8 wireless rec

　　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

　　 Wireless microphone from the sound into electrical signals, and then become high-frequency radio waves withered emission, and then receive back demodulation, amplification, reduction into sound this entire process, there are many aspects, one did not notice the link may It can work, but its stability, scope of work will be reduced a little, did not notice another link, will be reduced a little, the use of narrowing the point, so cumulative, multiple links at the same time loopholes, wireless microphone is not being Interference, is "running frequency", even if the distance can not be used normally. On the contrary, all aspects have noticed that the capability of wireless microphone to resist interference will be greatly enhanced, the stability will be greatly improved, and the normal use can be made even if the use distance is far beyond the use range specified by the manufacturer. The following is the wireless microphone in the selection, operation and use

　　With the popularization and widespread use of wireless microphone, how can we better play their superior role in the operation should pay attention to the following issues: 　　First, how to buy Wireless microphone transmitter battery 　　In order to ensure the normal use of the system does not appear signal distortion and frequency interference, you must use the battery can be sufficient, if the conditions are optional, choose alkaline 9V battery. 　　Second, how can we know as soon as possible whether the transmitter battery energy is sufficient 　　Third, how to replace the battery halfway in the show 　　During the performance of the battery replacement should be convenient, fast and easy. It is a good idea to turn on the "dumb" switch of the console channel and leave the Wireless microphone in a mute state. For example, a mixer without this function can turn off the output of the wireless microphone receiver and turn it off If the receiver does not output the vol

　　 Wireless microphone , also known as wireless microphone, consists of two parts, transmitter and receiver, commonly referred to as a wireless microphone system. The transmitter is battery powered and the microphone transforms the sound into an audio electrical signal that, after being processed by internal circuitry, emits radio waves containing audio information into the surrounding space. The receiver is generally powered by the mains. The receiving antenna receives the radio waves from the transmitter. After being processed by the internal circuit, the receiver extracts the audio signal and sends it to the sound reinforcement system through the output signal line to complete the wireless transmission of the audio signal. A receiver usually can contain 1 set, 2 sets or 4 sets of receiving circuits, respectively, to receive 1, 2 or 4 Wireless microphone signal, of which two are the most common. 　　After years of development, UHF wireless microphone technology has been

　　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

　　 Shotgun microphone 　　The purpose of using these devices is mainly to enhance the pickup capability in the axial direction, while attenuating side interference noise. In other words, let the microphone play its directivity as much as possible, in order to avoid unwanted noise and ambient sounds. 　　To do this, the system must block signals in unwanted directions and postpone the input of these signals. So its operating principle is based on the phase offset effect. First of all, the system has series interference tubes of different sizes, allowing the signals in the axial direction to arrive at the same time, and forcing the signal in the non-axial direction to reach the delay. The idea comes from Harry Olson, who has many inventions and also joined the current gun-type Mike's R & D team. 　　 BY-VM01 Condenser Mini Microphone 　　The BOYA BY-VM01 mini Microphone is designed for recording audio while making videos, along with this mic your camera can create highe

　　Opportunities for people to use microphones are frequent, but not many people are really good at using microphones. The so-called "good" is nothing more than a good pickup, long life and harmless to health. Here are some of the big mistakes I often see and are taboo we use. 　　1. Try not to beat the microphone when the sound and the microphone inflatable 　　As the microphone part of the pickup more sophisticated, and the parts are very delicate, beat the microphone or blow to the microphone can easily cause damage or parts shift, the final impact on sound quality. 　　2 avoid microphone away from the source too far too close 　　Microphone pickup the best distance of about 10 cm. Some "leadership" speech is far away from the microphone, and some singers close to the microphone, resulting in excessive pickup sound too small, then push the volume fader up to easily lead to howling; too close to the speech Sound of air also picked up, issued a "puff pu
