一场精彩的演出，不仅对表演者有要求，对舞台灯光音响设备也是有严格的控制和要求。很多人认为舞台音响就是音箱和调音台。实际上，舞台音响设备，需要有10个不同的设备来支撑整个舞台音响系统，这才能将舞台音响效果发挥到，下面来看看具体有什么设备：
A wonderful performance not only requires performers, but also strict control and requirements for stage lighting and sound equipment. Many people think that stage sound is a speaker and a mixer. In fact, professional stage sound equipment requires 10 different equipment to support the whole stage sound system, which can bring the stage sound effect to the extreme. Let's take a look at the specific equipment:
1、调音台：具有多个信道输入，每个信道的声音可以进行单独的加工处理，并且拥有左、右声道、混合、监听等的输出的一种声音混合设备。是音响师、录音师和作曲家进行音乐、声音创作的重要设备。
1. Mixer: a sound mixing device with multiple channel inputs, each channel of sound can be processed separately, and has the output of left and right channels, mixing, monitoring, etc. It is an important equipment for sound engineers, recording engineers and composers to create music and sound.
2、功放器：将音频电压信号转换成定额功率信号用于驱动扬声器发声的设备。
2. Power amplifier: a device that converts audio voltage signal into rated power signal to drive loudspeaker to produce sound.
3、分频器：实现分频的电路或装置称为分频器。分频器的种类有很多，根据其分频信号的波形不同，有正弦分频和脉冲分频两种。它的基本作用是，根据组合音箱的要求，将全频带声频信号分成不同的频段，使扬声器单元得到合适频带的激励信号，工作在状态。
3. Frequency divider: the circuit or device to realize frequency division is called frequency divider. There are many kinds of frequency divider. According to the different waveforms of the frequency divider signal, there are two kinds of frequency divider: sinusoidal frequency divider and pulse frequency divider. Its basic function is to divide the whole frequency band audio signal into different frequency bands according to the requirements of the combination speaker, so that the speaker unit can get the excitation signal of the appropriate frequency band and work in the state of the sound.
4、混响器：在歌舞厅音响系统和大型舞台灯光演唱会场里，非常重要的一个部分就是对人声的混响处理。人的歌声经过混响处理后，可以产生一种电子音响的美感，使歌声别具一番韵味。
4. Reverberator: in the sound system of song and dance hall and large stage lighting concert venue, a very important part is the reverberation processing of human voice. After reverberation processing, people's singing can produce a kind of aesthetic feeling of electronic sound, which makes the singing unique.
它可以对一些业余歌手嗓音中存在的某些缺陷，如沙哑、喉音和尖噪的声带杂音经过混响处理进行掩饰，使声音不那么难听。另外，混响声还可以弥补业余歌手由于未经过专门的发声训练而产生的音色结构中泛音不丰富的现象。这对舞台灯光演唱会举办的效果非常重要。
It can cover up some defects in the voice of some amateur singers, such as hoarseness, throat and sharp vocal cord noise, so that the voice is not so bad. In addition, reverberation can make up for the lack of overtones in the timbre structure of amateur singers who have not received special vocal training. This is very important for the effect of stage lighting concert.
5、变调器：由于人们的嗓音条件各不相同，在演唱时对伴奏音乐的音调要求也各不一致，有的人希望低些，有的则需要高些。这样，就要求伴奏音乐的音调应适应演唱者的要求，否则将会感到歌声与伴奏很不和谐。如果使用伴奏带则要求使用变调器进行变调处理。
5. Tone changer: because people's voice conditions are different, they have different requirements for the tone of accompaniment music when singing. Some people want to be lower, while others need to be higher. In this way, the tone of accompaniment music should be adapted to the requirements of the singer, otherwise the singing and accompaniment will feel very discordant. If the accompaniment tape is used, it is required to use the tone changer to change the tone.
6、效果器：提供声场效果，包括混响、延时、回声和对声音进行特殊处理的音响设备。
6. Effector: sound equipment that provides sound field effects, including reverberation, delay, echo and special processing of sound.
7、压限器：是压缩器与限制器合并的统称。
7. Pressure limiter: it is a general term for the combination of compressor and limiter.
8、均衡器：是对不同频率进行提升、衰减,调整低音、中音、高音比例的设备。
8. Equalizer: it is a device to enhance and attenuate different frequencies and adjust the proportion of bass, midrange and treble.
9、扬声器和音箱：扬声器是将电信号转换成声信号的器件。按原理区分有电动式、电磁式、压电陶瓷式静电式和气动式。
9. Loudspeakers and speakers: loudspeakers are devices that convert electrical signals into acoustic signals. According to the principle, there are electric type, electromagnetic type, piezoelectric ceramic type, electrostatic type and pneumatic type.
音箱又称扬声器箱，是把扬声器单元装入箱体中的装置，它不是发音部件，而是显示和丰富低音的助声部件。大体上可以分为叁种：封闭式音箱、倒相式音箱、迷宫式音箱。
Speaker box, also known as speaker box, is a device to put the speaker unit into the box. It is not a sound component, but a sound aid component to display and enrich the bass. Generally speaking, it can be divided into three types: closed speaker, inverted speaker and labyrinth speaker.
两路音箱
Two way speakers
10、话筒：话筒是将声音转换成电信号的一种电声换能器件。是音响系统中种类多的一个单元，按其指向性来区分可分为无指向性(圆形)、指向性(心型、超心型)和强指向性，其中无指向性是专门为乐队拾音使用的。指向性是用于语音、歌声等音源拾音的。
10. Microphone: a microphone is an electroacoustic transducer that converts sound into electrical signals. According to its directivity, it can be divided into non directivity (circle), directivity (heart, super heart) and strong directivity. Non directivity is specially used for band pickup. Directivity is used to pick up voice, song and other sound sources.
