　　There are three types of microphones: dynamic microphones, condenser microphones, and ribbon microphones. How to select a microphone is not simply to see which high price represents good quality, only the most suitable microphone is the best microphone. Most know what kind of microphone is best, first look at the occasion, then look at the demand, let's take a look at their respective advantages and disadvantages of the three microphones. 　　The sensitivity of the dynamic microphone is not high enough. Compared with the Condenser microphone , it cannot pick up more details, but it is also not easy to pick up the ambient noise. It is very suitable for use on the stage and it is not easy to produce feedback and howling. Another advantage of insensitivity is that the sound pressure level is large, that is, it can tolerate very loud sounds without sonic booming. For example, picking up snare drums at close range on the stage, the sound of excellent drummers is very loud. ...

　　The way the sound decays in the room is an important factor that affects the sound recording. Reverb on the role of sound is two-sided, can be better can be worse, reverberation time is one of the important conditions. Reverberation time refers to the time from when the sound source stops sound until the sound disappears completely. In a more technical language description is: the sound attenuation 60dB time required. Reverb time must be very short for voice and vocal recordings ("silent" room). Control room reverberation time is relatively short. The reverberation time between the sound and music usually depends on the type of music. The impulse response of a room (sound taken from an exploding balloon) shows all the independent reflections. 　　In the PA system, feedback over-performance is howling, which is the performance of  microphone  gain gain limit, the result of the peak superimposed.

　　Everyone's voice is unique, which creates the artistic and fun sound. Each voice has its own unique sound wave characteristics, making their own voice and others are different. 　　From men to women, ranging from rough to smooth, from darkness to lightness, the different indicators of looking at the voice are almost endless and none of them are the same. So this also means that no single microphone can completely capture these differences. 　　Microphone own frequency attribute 　　It should be noted that each microphone has its own unique frequency attributes, aware of this is very important. This frequency attribute mainly refers to the frequency response, but fundamentally speaking, each microphone will still apply its own frequency attribute to the sound of its reception, no matter how straightforward the frequency curve described on the microphone's instruction sheet is. 　　Microphone for the broadcaster is a very important item, in the selection often have to co...

　　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 ...

　　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...

　　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...

　　When using a Wireless Microphone , there is always the problem of interference between the systems themselves. 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 spacing between frequencies, depending on the design of the system receiver, may require an interval of 1 MHz from the nearest neighbor to the entry level receiver. The more expensive receivers usually have narrower adjustment "windows" that allow for a smaller intermodulation frequency separation between each system. 　　In order to avoid intermodulation distortion, choose the calculated frequency of mut...
