How to choose a mixer in professional audio engineering

　　Professional audio engineering is a complex project with many items, and the mixer is the core equipment in professional audio engineering, which is related to the quality and stability of the entire project. So how should a mixer be selected in professional audio engineering?

　　The main function of the mixer is to amplify, route and distribute the multi-channel input signals, and then group and output them after sound effect modification. It is the core equipment in professional audio engineering. The mixer can be divided into digital mixer and analog mixer according to the signal output method, and the number of input channels can be divided into 6, 8, 12, 16, 24, etc., each input channel The channel performance and structure can be different. Each input channel can accept one level signal input. If it is a stereo signal, two channels are required.

　　The audio signal in the digital mixing console is digital and is fully automated with low total harmonic distortion and equivalent input noise. Often used in demanding audio systems. Analog mixers use traditional analog methods for signal processing, with mature technology and low cost, but analog mixers have stable performance and are not easily affected by external factors.

　　Digital mixing consoles and analog mixing consoles have their own characteristics. If it is a large-scale comprehensive sound reinforcement venue, digital mixing consoles are recommended, because digital mixing consoles have rich interfaces and audio processing functions, which can meet different scenarios. and specific functional requirements. If it is a small fixed meeting place, it is recommended to use an analog mixing console, which is low in cost, stable in the system and simple in operation, and is suitable for non-professional operations.
