　　Today's microphones have become an integral part of our daily lives. The so-called science has its own strengths and specializes in surgery. The same is true for microphones. Different types of microphones are also used for different purposes. Microphones are not only varied but also function-specific, So whether you use the microphone or optional microphone have to choose. Microphone selection is usually based on the use of the occasion, the purpose and the performance of the microphone and sound quality and sound as the principle of selection. 　　According to the microphone transduction principle of different, can be divided into electric (moving coil, with), capacitive, electromagnetic, semiconductor, voltage type. Electric microphones have a long history and are widely used. The real Condenser microphone is excellent performance by the majority of recording workers of all ages, has now become the mainstream. 　　According to the different directivity of the microph

　　For those who have just come in contact with the condenser microphone , you may neglect the moisture-proofing problem of the condenser microphone or do not know the condenser microphone needs to be moisture-proof. When the noise becomes small and dull, the problem of puffing noise is damp or oxidized, importance. 　　How to protect the condenser microphone ? 　　1. Avoid using the microphone in humid environment. If the environment can not be changed, wipe the microphone with a soft cloth after use to prevent the internal circuit wires from short-circuiting. 　　2. Use the bracket when using the microphone in summer or indoor temperature is very high, to prevent the sweat from corrosion caused by holding the microphone for a long time, which will affect the microphone. 　　3. Some people used to stick to the microphone on the mouth, saliva or Kazakhstan gas can affect performance, you can use the spray-proof net / spray cover, spray is not only to prevent the jet sound Oh. 　　

About volume. The volume control is the key to the use of the microphone . Generally speaking, the volume should be slightly controlled, that is, the singer should have a smaller volume than singing without a microphone . This control volume to maintain high, middle and low harmony of the three voice zone, because accompaniment music is always transferred to a volume intensity, if the volume of the three voices are not uniform, it will appear in the treble or bass or strong Or weak sound effects, affecting the integrity of the song. Some singers or treble poor, or weaker bass, according to their own situation, the use of microphone from the mouth to adjust the distance. This adjustment depends on the sensitivity of the sound. In addition, the song of the AAC singing, the microphone must be close to the mouth, in order to better show the characteristics of this singing. About breathing. Breathing in the microphone on the performance is very sensitive. Especially for the high sensit

　　 Wireless Microphone , Microphone Usage Precautions We all know? Talk to everyone today Wireless microphone, Microphone Notes, I hope we can provide some help, let alone know that we come to understand. 　　1, impedance matching 　　The best match between the output impedance of the wireless microphone and the input impedance of the amplifier when using a wireless microphone is the best match, with a mismatch ratio of more than 3: 1 that can affect the transmission. For example, the 50Ωwireless microphone connected to the input impedance of 150Ω amplifier, although the output can increase nearly 7Db, but the high and low frequency sound will be a significant loss. 　　2, working distance and near effect 　　Usually, the working distance between the wireless microphone and the mouth is between 750px and 1000px. If the distance is too long, the echo will increase and the noise will increase relatively. Working distance is too close, because of the signal is too strong and distort

　　Microphone for the broadcaster is a very important item, in the selection often have to consider a variety of factors. In a wide range of microphones, there is no such thing as "a microphone is the best." There are many different types of microphones on the market, each of which has its own unique properties and uses, and produces a different sound texture. 　　Such as moving coil, capacitor, aluminum band, sound pressure (boundary), dual stereo, MS, etc .; each type has a different pickup pattern, the diaphragm of different sizes, the frequency response changes, the sensitivity , Own noise, and the degree of noise, wind or blast sound handling, different combinations will affect the microphone delivery, each project should not be underestimated 　　It is really hard for the dynamic microphone to pick up the very high frequency part of the eraser. However, the dynamic microphone can perform satisfactorily when picking up a strong kick drum or snare sound. Dynamic

　　It is not easy to choose a suitable microphone, especially if you do not know the difference between omnidirectional microphones and supercardioid microphones, that is, the various microphone pickup patterns. In the video below, Stephen Harrod, who has spent years of audio work, will share with you some of his thoughts on what pickup patterns are and how different projects work best for them. 　　Microphone pickup mode refers to the microphone relative to the sound from different directions or angles of sensitivity, simply, that is, the microphone "to listen to the same direction of the voice of the ability. 　　Omnidirectional microphones have a spherical pickup pattern that, from the point of view of the microphone, picks up the sound evenly from all directions around it, that is it has the same sensitivity at 360 degrees so you will hear the surroundings All sounds. 　　What scenario does it work for? An omnidirectional microphone is the best choice if you need to r

　　Whether it is commercial, wedding or movie audio recording, different microphones will give people a different video perception. So there are many things to note when recording audio, from the microphone placement to the microphone itself. Which one is suitable for you? 　　For most productions, it is important to get the right audio for the first time, rather than revising later techniques such as audio editing, which can be time-consuming and expensive (although mixing is required in certain contexts, Dubbing and other special treatment). Then we start from understanding the microphone! 　　Handheld microphones are perfect for interviewers or moderators, whether wired or wireless, and are often used in noisy environments where you need to pan and run, providing a very rich and complete sound. It can also be used on a stand to capture the audio of a subject that will not move. If you do not want the microphone to appear in the lens, a lavalier or shotgun microphone would b

　　Live live concert, is very concerned about the radio quality. A singer on the stage to use the microphone to reproduce the wonderful voice of the song, you must first learn to take the right microphone position. Although the stage to take the microphone strange, some do not have to sing on the mouth, take the microphone position do not have to pay attention to, but to incorrect use of posture, will greatly affect the sound effects of the microphone. 　　To celebrity singer Fei Yuqing use Wireless microphone singing can be described as classic, see him make good use of the microphone. He took the microphone for decades the same standard to take the law, the microphone is like his own body, take the law carefully take the law can feel his passion for music. 　　1. Maintain an appropriate distance of 10 to 15 cm (good microphone to punch wide; poor from the three fingers wide) 　　Mouth and microphone to maintain proper is necessary, if the distance is too close to the mouth wi

　　In theatrical performances, big party or TV show, I often find that many users feel sorry for the wrong posture and improper use of the wireless microphone . Because of the mistakes on the use of a valuable microphone not only can not play the original factory has Of the superior features, and buried the original sound quality, the result than using a cheap microphone show the sound even worse. - 　　Many sound controllers will only pick the microphone itself sound quality, but do not know how to guide the user how to use the microphone to the best sound quality. Do not think that as long as you have a valuable microphone, you can get a satisfactory sound, in fact, the microphone is only part of the sound system, if the user of the microphone with other audio equipment, adjustment and use of improper operation, even with the world's most expensive Of the microphone, it is difficult to show the satisfactory sound quality! Just like the car people do not understand the c
