要配备化的音响设备。音响设备是保证舞台音响效果的重要基础，它直接关系到舞台艺术呈现的成功与失败。舞台音响系统是由信号源设备、信号处理设备、功率放大器和扬声器等设备连接而成，舞台演出对音响调试和音箱布置的位置及系统安装有很多具体的技术要求，这就要求调音师除了掌握音响设备的使用外，还要掌握一定的调音技巧，通过自己的听觉和对声源的理解，调整音响设备以及对音频信号的加工处理，达到真实音响的再现。可以说，音响设备配置与调试是舞台艺术绽放的重要基础。
Professional audio equipment should be equipped. Sound equipment is an important foundation for ensuring stage sound effects, which directly affects the success or failure of stage art presentation. The stage sound system is composed of signal source equipment, signal processing equipment, power amplifiers, speakers, and other equipment connected. Stage performances have many specific technical requirements for sound debugging, speaker placement, and system installation. This requires the tuner to not only master the use of sound equipment, but also master certain tuning skills, through their own hearing and understanding of the sound source, Adjust audio equipment and process audio signals to achieve true audio reproduction. It can be said that the configuration and debugging of audio equipment are important foundations for the blooming of stage art.
在对人声的美化、修饰上，可以通过调音台上面的输入通道中的四段均衡器，对音色进行频率处理来提高音色的艺术表现力。根据德车柏林音乐研究所资料介绍，调音台中的四段均衡器分为四个频段：
In terms of beautifying and embellishing the voice, we can use the four section equalizer in the input channel above the Mixing console to process the voice frequency to improve the artistic expression of the voice. According to the introduction of the German Music Research Institute, the four band equalizer in the mixer is divided into four frequency bands:
6~16千赫兹。影响音色的表现力、解析力;第二，MID高音。600~6000赫兹，影响音色的明亮度、清晰度;第三，MID高音。200~600赫兹，影响音色和力冲和结实度;第四，低音。20~200赫兹，影响音色的混厚度和丰满度。
6-16 kHz. Affects the expressive and analytical power of timbre; Secondly, MID treble. 600-6000 Hz, affecting the brightness and clarity of the sound; Thirdly, MID treble. 200-600 Hz, affecting timbre, impact, and firmness; Fourth, bass. 20-200 Hz, affecting the mixed thickness and fullness of the timbre.
如果高频段频率过弱，其音色就变得富有色彩、韵味;如果高频段频率过强，音色就会变得尖噪、嘶哑、刺耳。如果中频段的频率过弱，音色就变得暗淡、朦胧;如果中频段的频率过强，其音色就会变得呆板。如果中低频段的频率过弱，音色会变得空虚、无力;如果中低频段的频率过强，音色会变得生硬，失去活力。如果低频段的频率过弱，音色会变得单薄、苍白;如果低频段的过强，音色会变得浑浊不清。
If the high-frequency frequency is too weak, its timbre becomes rich in color and charm; If the high-frequency frequency is too strong, the sound will become sharp, hoarse, and harsh. If the frequency in the middle frequency band is too weak, the sound will become dim and hazy; If the frequency in the mid range is too strong, its tone will become dull. If the frequency in the mid to low frequency range is too weak, the timbre will become empty and powerless; If the frequency in the mid to low frequency range is too strong, the tone will become stiff and lose vitality. If the frequency in the low frequency range is too weak, the sound will become thin and pale; If the low-frequency band is too strong, the sound will become cloudy and unclear.
要使音色有美感，就要泛音丰富、有层次，使歌声有音响美，听众听起来才会悦耳动听。低音过量，声音会浑浊不清;高音过量，声音会尖噪刺耳。提升某一频段后，还应考虑其他频段的影响，要从总体上考虑歌声的清晰度和丰满度。
To make the sound beautiful, it is necessary to have rich and layered overtones, and make the song sound beautiful, so that the audience can hear it pleasantly. Excessive bass can make the sound cloudy and unclear; Excessive treble can cause sharp and harsh sounds. After upgrading a certain frequency band, the impact of other frequency bands should also be considered, and the overall clarity and fullness of the song should be considered.
论人声、歌声，还是乐器的声音，它们都不是一个单音，而是一个复合音，也就是由声音的基音和一系列的泛音所构成。这些泛音都是基音频率的位数，物理学中称其为分音，电声学中称其为谐波，音乐中称泛音。它对音色的特性有非常重要的影响。这些泛音的数量和泛音幅茺的不同构成音色的频率特性曲线。这条曲线就体现了音色的表现力。例如，钢琴的低音频率是 27.5赫兹，高音频率是4186赫兹，而钢琴有10多个泛音，它的高频可达 10~20千赫兹，一般可测到 16 个泛音或 24 个泛音。这些泛音可分为低频泛音、中频泛音和高频泛音。如果低频泛音的幅度较强，音色就表现得混厚;中频泛音的幅度比较强，音色就表现得圆润、自然、和谐;高频泛音的幅度比较强，音色就表现得明亮、清透、解析力强。
In terms of human voice, singing voice, or musical instrument sound, they are not a single tone, but a composite tone, which is composed of the fundamental tone of the sound and a series of overtones. These overtones are the digits of the fundamental frequency, referred to as partials in physics, harmonics in electroacoustics, and overtones in music. It has a very important impact on the characteristics of timbre. The number and amplitude of these overtones form the frequency characteristic curve of the timbre. This curve reflects the expressive power of timbre. For example, the bass frequency of a piano is 27.5 Hz, the treble frequency is 4186 Hz, and the piano has more than 10 overtones, with a high frequency of 10-20 kHz. Generally, 16 overtones or 24 overtones can be measured. These overtones can be divided into low-frequency overtones, intermediate overtones, and high-frequency overtones. If the amplitude of low-frequency overtones is strong, the timbre will appear mixed and thick; The amplitude of mid frequency overtones is relatively strong, resulting in a rounded, natural, and harmonious tone; The amplitude of high-frequency overtones is relatively strong, resulting in a bright, clear, and analytical tone.
噪音指的是从音箱发出的与演出无关、观众并不希望听到的而又听到声音。噪声出现在演出当中将会极大地影响演出的质量，严重时也会妨碍演出的正常进行。
Noise refers to the sound emitted from the speaker that is unrelated to the performance and the audience does not want to hear. The appearance of noise during a performance will greatly affect the quality of the performance, and in severe cases, it can also hinder the normal progress of the performance.
一般而言，交流声是因为扩声系统中的音频设备滤波电容元件老化或是失效电容量减少而产生的。同时，连接音频设备的插件损坏或接触不良都可能产生低频噪声。为了避免这种噪音的产生，应该定期对设备进行检查和维护，以便能及时排除故障。目前还不能排除的是扩声系统中的音频设备固有的本底噪声，只能想办法减弱。这就需要在选用音频设备时考虑信噪较高的设备，另外，还可以在扩声系统中使用噪声门。调光设备中的可控硅也会对音频设备产生干扰，特别是在调光后压光时可控硅会生产高次谐波干扰音频设备。解决这一干扰，可将灯光设备和音响设备用不同的变压器分别供电，割离通过变压器内阻的偶合，将硅柜灯具的供电线路进行屏蔽、减弱供电线路通过空中的电磁干扰。
Generally speaking, communication sound is generated due to the aging or reduced capacitance of the filtering capacitor components of audio equipment in the sound reinforcement system. At the same time, damage or poor contact of the plug-in connecting the audio device may cause low-frequency noise. In order to avoid the generation of such noise, the equipment should be regularly inspected and maintained in order to promptly troubleshoot. What cannot be ruled out at present is the inherent background noise of audio devices in the sound reinforcement system, and we can only find ways to reduce it. This requires considering devices with higher signal-to-noise when selecting audio devices, and noise gates can also be used in sound reinforcement systems. The controllable silicon in the dimming device can also cause interference to the audio device, especially when the dimming is pressed, the controllable silicon will produce high-order harmonic interference to the audio device. To solve this interference, different transformers can be used to power the lighting equipment and audio equipment separately. The coupling through the internal resistance of the transformer can be cut off, and the power supply line from the silicon cabinet to the lighting fixtures can be shielded to reduce electromagnetic interference from the power supply line through the air.
音响效果是舞台艺术的重要表现手段，观众在剧院里除了用眼睛观看，还要用耳朵去倾听。音响效果是听觉上的点染，是辅助演出的另一种艺术手段，从这种意义上来说，音响效果是艺术中的另一种语言手段。 音响效果的综合作用，就是把舞台上具有音响性质的各个部分综合起来，树立一个完整的音响形象，在纳入到舞台气氛的整体形象之中，使观众能获得一个可感的立体形象。
Sound effects are an important means of expression in stage art, and audiences in theaters not only watch with their eyes, but also listen with their ears. Sound effects are auditory embellishments and another artistic means of assisting performance. In this sense, sound effects are another language means in art. The comprehensive effect of sound effects is to integrate various parts of the stage with sound properties, establish a complete sound image, and incorporate it into the overall image of the stage atmosphere, so that the audience can obtain a perceptible three-dimensional image.
