How to test condenser microphone ?

　　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.

BOYA BY-WM5 wireless microphone is for use with DSLR cameras, camcorders. The 2.4 GHz GFSK system result in strong anti-interference, good security and stability.

　　In view of this phenomenon, people put forward a variety of methods to improve the microphone sound gain such as reasonable arrangement of sound field,  increase the sound absorption material, change the sound reflection characteristics and so on physical means, so as to avoid such phenomena as possible, To meet the sound pressure requirements of normal sound reinforcement purposes, not repeat them here.
　　In general, through the compensation of electro-acoustic equipment to achieve the purpose of improving microphone gain, which is commonly used means. Among them, the electroacoustic device compensation means are also divided into two kinds of active mode and passive mode.
　　The equalizer used for feedback control is to find out the high bump of the frequency response curve. By controlling the points, the frequency response curve is balanced, so that the maximum gain gain space (2-6db) of the sound reinforcement system is obtained.

How to install a wireless microphone

　　 Wireless Microphone , also called wireless microphone, can restore and amplify the sound. Compared with wired microphone, it is more convenient and more and more popular with consumers. It is widely used in KTV, audio-visual room and conference room. Perhaps so many people still think so: as long as the equipment, you can talk on it. In actual fact, if you do not understand its working principle and the use of precautions, it would not be able to really use the Wireless Microphone. Below, Wo sound engineering to share with you this knowledge. 　　How Wireless Microphone works: 　　 Wireless Microphone is mainly composed of transmitting part and receiving part. The transmitter part is powered by a battery. The microphone converts the sound into an audio signal. After being processed by an internal circuit, a radio wave containing audio information is transmitted to the surrounding space. The receiving part is generally powered by the mains. The receiving antenna receives

When are condenser microphones used

　　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.

What is the range of a wireless microphone

　　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
