Types of performance stage audio equipment!Car stereo Vendor

　　The speaker, also known as the speaker box, is a device that puts the speaker unit into the cabinet. It is not a sounding component, but a sound-assisting component that displays and enriches the bass. It can be roughly divided into three types: enclosed speakers, inverted speakers, and labyrinth speakers. The speaker equipment is quite concerned about the location factor given to it when the stage is set up.

　　There are many types of professional stage audio equipment. In general, the performance stage audio equipment is composed of microphone + mixer + audio amplifier + speaker. In addition to microphones, audio sources sometimes require DVDs, computers to play music, etc. Computers can also be used. But if you want professional stage sound effects, in addition to professional stage construction staff, you also need to add sound equipment such as effectors, timing devices, equalizers, and voltage limiters.

　　Below we introduce in detail what are the main performance stage audio equipment:

　　1. Mixing console: a sound mixing device with multiple channel inputs, each channel's sound can be processed separately, and with left and right channels, mixing, monitoring, etc. output. It is an important equipment for sound engineers, sound engineers and composers for music and sound creation.

　　2. Power amplifier: A device that converts audio voltage signals into rated power signals for driving speakers to produce sound. The matching condition of the power amplifier power is that the output impedance of the power amplifier is equal to the load impedance of the speaker, and the output power of the power amplifier matches the nominal power of the speaker.

　　3. Reverberator: In the performance stage sound system and large-scale stage lighting concert venue, a very important part is the reverberation processing of the human voice. After human singing is processed by reverberation, it can produce a kind of beauty of electronic sound, which makes the singing voice unique. It can conceal some defects in the voice of amateur singers, such as hoarseness, throat noise, and noisy vocal cord noise through reverb processing, so that the voice is not so unpleasant. In addition, the reverberation sound can also make up for the lack of overtones in the timbre structure of amateur singers who have not undergone special vocal training. This is very important for the effect of stage lighting concerts.

　　4. Frequency divider: A circuit or device that realizes frequency division is called a frequency divider. There are many types of frequency dividers. According to the different waveforms of their frequency division signals, there are two types: sine frequency division and pulse frequency division. Its basic function is to divide the full-band audio signal into different frequency bands according to the requirements of the combined loudspeaker, so that the loudspeaker unit can obtain the excitation signal of the appropriate frequency band and work in the state.

　　5. Pitch shifter: As people's voice conditions are different, the pitch requirements of the accompaniment music when singing are also different. Some people want to be lower, and some need to be higher. In this way, it is required that the tone of the accompaniment music should be adapted to the requirements of the singer, otherwise the singing voice and the accompaniment will feel very inharmonious. If you use an accompaniment tape, you need to use a pitch shifter for pitch shifting.
