A mixer console, also known as an audio mixer or soundboard, is a device used in professional audio engineering and music production that allows multiple audio signals to be mixed together into a single output. It contains various knobs, sliders, and buttons that control the level, timbre, and dynamics of each individual audio signal, as well as the overall balance of the mix.

The mixer console typically has multiple input channels, each with its own preamplifier, equalizer, and routing switches. These channels are then mixed together and summed to a main output, which can be recorded or sent to a PA system for live broadcast or performance. Some mixer consoles also have built-in effects processors, such as reverb, delay, and chorus, that can be applied to individual channels or the master output.
