1. Coordinate multiple microphones

 - Radius wine is a very important factor to determine the distance from the microphone to the sound source (that is, how to put the microphone to pronounce how far objects). In addition, there are other equally important factors such as: big sound intensity in the near vuec microphone, microphone will use numbers and especially music played through a microphone that

- In the field of pop and musical entertainment, people use stereo microphone with high intensity by using a combination of separate microphones. Meanwhile, it is used mainly oriented and given microphone signal from the microphone signal through the audio mixer (mixer). The coordination duty mixer audio signals from the individual microphones together, they tend to have PAN functionality to create the effect Stereo. For this method to be effective, the individual microphones to be placed far apart so that the sound from a sound source does not transmit simultaneously to multiple microphone beside that only through a microphone dedicated to it. Especially on stage, when the sound level is too large, only a single separating sound is set separately for each group micro instruments, and a special microphone, away from other microphones, for the solo instrument.When audio compression (tone pressure) of two individual microphones greater than 15 dB, it is necessary to place them far apart to separate sounds

- People often use the impetus for the solo instrument or sing a solo, because this kind of microphone signals obtained in the region near the microphone sound without catching the distant sound. The microphone sound momentum of high-compression, high activity and safety. These are important points in the technical collection and pop music entertainment. To reduce the abnormally high sound level of unwanted, they transfer the sound from the microphone via sound reduction device, called a "limiter" (device limit)

- The result of this technique is going to be recording clear sounds of each instrument with a high-intensity sound without having to increase the level of pronunciation.

- However, the said recording techniques can not be applied to the field of classical music (or music scholar). Here, the elements: space (the studio, or where performed, if the receiver directly), motivation, and the sound mix is ​​very important. Especially when placing microphones too direct (close, straight on) until the instrument, we can not mix the sounds of the different instruments (orchestra) into a common chord. Therefore, when recording classical music one must resort to micro-oriented type. This is very important but often never given any thought. The use of a microphone for the whole orchestra and pop music is an unfortunate omission. Especially, in the orchestra's strings, because they can not put the microphone closer to the user so as to orient the microphone type. The only exception is when the herd contrebasse while recording pop music performances, a new one microphone placed close to the board. The collection of classical music should sound requires clear and bright, with no virtual sound. When collecting electronic music, to get the desired sound, people use the microphone to the microphone support.

2. Techniques used in combination with the main microphone microphone support

- Contrary to how to coordinate multiple microphones, this technique has the advantage that the application can test gianvaf. Just a little experience can also be a good record, because we can make a resounding (the studio). However, when using the microphone support we can incur expensive and a little more difficult. In fact, we must place the main microphones that sound we hear more prominent through the sound through the microphone support. Ideal place to put a microphone (ie the distance to the sound source) depends on the radius of wines and surroundings of the studio. Actually, there is no common pattern, which was mainly due to practical experience.

- Often people should use as little as possible microphone support, and with a suitable low intensity (usually less than 20 dB compared to the main microphone). However, the main method of coordination with microphone microphone support slightly more expensive and costly. Techniques used in the micro we should use many different solutions.
