音响工程是一个品目众多的复杂性工程，调音台又是音响工程中的核心设备，关系到整工程的质量及稳定性，那么在音响工程中调音台应该怎么选?
Sound engineering is a complex project with many items. The mixer is the core equipment of sound engineering, which is related to the quality and stability of the whole project. So how should we choose the mixer in sound engineering?
调音台的主要作用是将多路输入信号进行信号放大、路由分配、音效修饰后进行编组输出，是音响工程中的核心设备。调音台按信号输出方式可分为数字调音台及模拟调音台，输入通道数量的多少又可以分成6、8、12、16、24&尘颈诲诲辞迟;&尘颈诲诲辞迟;&尘颈诲诲辞迟;&尘颈诲诲辞迟;&尘颈诲诲辞迟;&尘颈诲诲辞迟;等多种，每个输入通道性能、结构可以各不相同，每个输入通道可接受一路电平信号输入，如果是立体声信号则需要两个通道。
The main function of the mixer is to amplify the multi-channel input signal, distribute the route, modify the sound effect, and then output it. It is the core equipment in the sound engineering. According to the signal output mode, the mixer can be divided into digital mixer and analog mixer. The number of input channels can be divided into 6, 8, 12, 16, 24, etc. each input channel has different performance and structure. Each input channel can accept one level signal input. If it is a stereo signal, it needs two channels.
数字调音台内的音频信号是数字信号，是全自动化处理，总谐波失真和等效输入噪声都很低。常被用于要求高的音响系统。模拟调音台都是采用传统的模拟方式进行信号处理，技术成熟，成本低，但是模拟调音台性能稳定，不易受外界因素影响。
The audio signal in the digital mixer is digital signal, which is fully automatic processing. The total harmonic distortion and equivalent input noise are very low. It is often used in demanding sound system. Analog mixer adopts the traditional analog way for signal processing with mature technology and low cost, but the performance of analog mixer is stable and not easy to be affected by external factors.
数字调音台跟模拟调音台都有各自的特点，如果是大型综合性的扩声场所，使用数字调音台，因为数字调音台有丰富的接口及音频处理功能，可以满足不同场景及特定功能需求。如果是小型固定会议场所，建议使用模拟调音台，成本低，系统稳定，操作简单，适用于非操作人士的操作。
Digital mixer and analog mixer have their own characteristics. If it is a large comprehensive sound reinforcement place, it is recommended to use digital mixer, because digital mixer has rich interface and audio processing functions, which can meet the needs of different scenes and specific functions. If it is a small fixed meeting place, it is recommended to use analog mixer, which has low cost, stable system, simple operation and is suitable for non operators.
