An analog mixer is an audio signal processing device, and its main functions include amplification, mixing, distribution, sound quality modification, and acoustic effects processing of multiple input signals, and then output them through the bus. In the audio industry, analog mixers are an important equipment, often used in broadcasting, stage amplification, audio program production and other systems for broadcasting and recording programs.
The core components of an analog mixer include input channels, output channels, busbars, aux sends, and aux returns. Each input channel has a gain control knob (gain) for adjusting the amplitude of the input signalA balance control knob to adjust the balance of the input signal between the left and right channelsand a volume fader to control the volume of the input signal in the output channel.
In addition, the analog mixer has a monitoring function that allows you to hear the input or output signals directly through the headphone jack. Operators can assign audio signals from different lines to different speakers according to the needs of the site. Common types of speakers include main amplifiers, monitors, monitors, and more.
However, compared to digital mixers, analog mixers have fewer inputs and outputs, for example, a typical analog mixer may only have 16 outputs, while a digital mixer for a large performance may have 32 inputs and outputs of 16 outputs. Still, the basic features of analog mixers meet most needs while being relatively low, so analog mixers are still preferred for smaller occasions and projects with limited budgets.
