音響工程是一個(gè)品目眾多的復(fù)雜性工程，調(diào)音臺(tái)又是音響工程中的核心設(shè)備，關(guān)系到整工程的質(zhì)量及穩(wěn)定性，那么在音響工程中調(diào)音臺(tái)應(yīng)該怎么選?
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?
調(diào)音臺(tái)的主要作用是將多路輸入信號(hào)進(jìn)行信號(hào)放大、路由分配、音效修飾后進(jìn)行編組輸出，是音響工程中的核心設(shè)備。調(diào)音臺(tái)按信號(hào)輸出方式可分為數(shù)字調(diào)音臺(tái)及模擬調(diào)音臺(tái)，輸入通道數(shù)量的多少又可以分成6、8、12、16、24······等多種，每個(gè)輸入通道性能、結(jié)構(gòu)可以各不相同，每個(gè)輸入通道可接受一路電平信號(hào)輸入，如果是立體聲信號(hào)則需要兩個(gè)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.
數(shù)字調(diào)音臺(tái)內(nèi)的音頻信號(hào)是數(shù)字信號(hào)，是全自動(dòng)化處理，總諧波失真和等效輸入噪聲都很低。常被用于要求高的音響系統(tǒng)。模擬調(diào)音臺(tái)都是采用傳統(tǒng)的模擬方式進(jìn)行信號(hào)處理，技術(shù)成熟，成本低，但是模擬調(diào)音臺(tái)性能穩(wěn)定，不易受外界因素影響。
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.
數(shù)字調(diào)音臺(tái)跟模擬調(diào)音臺(tái)都有各自的特點(diǎn)，如果是大型綜合性的擴(kuò)聲場(chǎng)所，使用數(shù)字調(diào)音臺(tái)，因?yàn)閿?shù)字調(diào)音臺(tái)有豐富的接口及音頻處理功能，可以滿足不同場(chǎng)景及特定功能需求。如果是小型固定會(huì)議場(chǎng)所，建議使用模擬調(diào)音臺(tái)，成本低，系統(tǒng)穩(wěn)定，操作簡(jiǎn)單，適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.
