What are the professional stage sound equipment?
2019-03-23
A wonderful performance not only requires the performers, but also has high requirements for the stage sound. Many people think that the stage sound is not a visible device such as a speaker or a mixer. In fact, the stage audio equipment in the professional audio system designer, you need to have 10 different devices to support the entire stage sound system, in order to maximize the stage sound effects.


1. Mixer
A sound mixing device having multiple channel inputs, each channel's sound can be processed separately, and having left, right channel, mix, monitor, etc. outputs. It is an important device for sound and sound creation by sound engineers, sound engineers and composers.



2, power amplifier

A device that converts an audio voltage signal into a calibrated power signal that is used to drive the speaker to sound. The matching condition of the power of the power amplifier is (1), and the output impedance of the power amplifier is equal to the load impedance of the speaker. (2) The output power of the power amplifier matches the nominal power of the speaker.



3, frequency divide

A circuit or device that implements frequency division is called a frequency divider. There are many types of frequency dividers, and there are two types of sinusoidal frequency division and pulse frequency division according to the waveform of the frequency division signal. Its basic function is to divide the full-band audio signal into different frequency bands according to the requirements of the combined speaker, so that the speaker unit obtains the excitation signal of the appropriate frequency band and works at the optimal state.



4, reverberator

In the dance hall sound system and the large stage lighting concert venue, a very important part is the reverberation of the human voice. After the reverberation of the human voice, it can produce an electronic sound, which makes the song have a unique charm. It can mask some of the flaws in the voices of some amateur singers, such as hoarseness, throat sounds and noisy vocal murmurs, so that the sound is not so ugly. In addition, the reverberation sound can also compensate for the phenomenon that the amateur singer is not rich in overtones due to the lack of special vocal training. This is very important for the effect of the stage lighting concert.



5, the shifter

Because people's voice conditions are different, the tone requirements for the accompaniment music are also inconsistent during the singing. Some people want to be lower, while others need to be higher. In this way, the tone of the accompaniment music should be adapted to the requirements of the singer, otherwise the singing and the accompaniment will be very discordant. If you use an accompaniment band, you will need to use a pitcher for transposition processing.



6, the effect
Provide sound field effects, including reverb, delay, echo, and audio equipment that specializes in sound processing.



7, the limiter
It is a general term for the combination of a compressor and a limiter. Its main role (1), protection amplifiers and speakers (speakers). (2) Create special sound effects.



8, equalizer
It is a device that boosts, attenuates, and adjusts the bass, midrange, and treble ratios of different frequencies. Its meaning has two aspects. 1. Make necessary compensation for the frequency response curve of the audio device or carrier so that the output sound is not distorted. 2. The sound signal is processed to meet the listening requirements for the purpose of creation. Under normal circumstances, the use of such devices is not many, so most people will choose to temporarily rent to the audio rental business.



9, speakers and speakers
A speaker is a device that converts an electrical signal into an acoustic signal. According to the principle, there are electric, electromagnetic, piezoelectric ceramic electrostatic and pneumatic. A speaker, also called a speaker box, is a device that puts a speaker unit into a box. It is not a sounding component, but a sound-assist component that displays and enriches the bass. Generally, it can be divided into three types: closed speakers, inverted speakers, and labyrinth speakers. The speaker device is quite concerned about the position factor of the stage when it is built.



10, microphone
A microphone is an electroacoustic transducer that converts sound into an electrical signal. It is the most diverse unit in the sound system. It can be divided into non-directional (circular), directional (heart-shaped, super-cardioid) and strong directivity according to its directivity. The non-directionality is specifically for the band. Used for pickup; directivity is used for sound pickup of voice, singing, etc.; strong directivity is to exclude the sound of the left and right sides and the back of the microphone pickup space in order to pick up the sound of a certain direction of sound. Specially using the principle of mutual interference of sound waves, a slender tubular microphone made using acoustic interference tubes, known as gun microphones, used in art stage and news interviews; dynamic microphones are distinguished by structure and application range. , aluminum ribbon microphone, condenser microphone, pressure zone microphone - PZM, electret microphone, MS stereo microphone, reverb microphone, pitch microphone and so on.



The sound system seen on the stage seems simple, but it is composed of 10 kinds of audio equipment. Therefore, it takes three minutes on stage and ten years of work. It is not only the performers, but also the staff behind the scenes. Especially the technicians of the stage sound system
