Other meanings of Mixing console
Audio Engineering
A mixing console (also called a mixing desk, mixer, or soundboard) is an electronic device for combining, routing, and processing multiple audio signals. It allows an engineer to adjust the level, tone, and spatial placement of each input, blend them into a coherent mix, and send the result to outputs such as loudspeakers, recording devices, or broadcast transmitters. Mixing consoles are central to live sound reinforcement, recording studios, broadcasting, and post-production, and range from small portable units with a few channels to large-format desks with hundreds of inputs and extensive automation.
A mixing console's primary job is to accept multiple audio inputs, adjust their levels, and combine them into one or more output buses. Each input channel typically includes a gain stage, equalization (EQ), auxiliary sends for effects or monitor mixes, and a pan control for stereo placement. The channel strip feeds a summing bus, where all signals are mixed together; the master section then routes the summed signal to main outputs, group buses, and auxiliary outputs.
Consoles also provide routing flexibility: signals can be sent to subgroups for collective control, to effects processors via sends, or to multitrack recorders via direct outputs. Modern digital consoles add extensive routing matrices, allowing any input to be assigned to any output or processing chain. The architecture of a console—whether analog or digital—determines its signal flow, noise performance, and operational workflow.
Analog consoles process audio using continuous electrical signals, with each channel's circuitry dedicated to that input. They are prized for their tactile immediacy, simplicity, and the subtle coloration of their preamps and equalizers. Classic analog desks, such as the Neve 8078 or SSL 4000 series, are still used in many studios for their sonic character.
Digital consoles convert audio to digital data and process it with DSP chips, offering recall of settings, automation, and powerful routing. They can store and retrieve complete mix snapshots, making them ideal for touring and broadcast. Digital consoles also include effects, dynamics, and EQ on every channel, and can be controlled remotely via software. Hybrid systems combine analog front ends with digital processing, and many modern consoles use digital control of analog circuits to retain analog warmth with digital convenience.
Mixing consoles are used in a wide range of settings. In live sound, they mix microphones and instruments for concerts, theaters, and houses of worship, often with extensive monitor mixing for performers. In recording studios, consoles route signals to multitrack recorders and provide monitoring and mixing for playback. Broadcast consoles are designed for radio and television, with features like fader starts, talkback, and redundancy.
Post-production facilities use consoles to mix dialogue, music, and sound effects for film and television, often with surround sound capabilities. Smaller mixers are used in podcasting, streaming, and home studios, while large-format digital consoles dominate major tours and broadcast trucks. The choice of console depends on the number of inputs, required features, and the operator's preference for analog or digital workflow.
Beyond the familiar channel strips, mixing consoles have many niche features and historical quirks. Some early consoles used vacuum tubes and had no EQ; equalization was added later as a separate outboard unit. The first transistor consoles appeared in the 1960s, and the first digitally controlled analog consoles emerged in the 1980s, such as the Neve 8100 series.
Some consoles include unique features like VCA (voltage-controlled amplifier) grouping, which allows faders to control multiple channels without affecting the audio path, and MIDI control for automation. The SSL 4000 series introduced 'Total Recall' in 1979, a system that stored knob positions as voltage values for later recall. In broadcast, consoles often have 'mix-minus' buses to prevent feedback when sending audio to remote guests. Some high-end consoles use 'summing' topologies that intentionally add harmonic distortion for a 'vintage' sound, while others strive for transparency.
The term 'mixing console' is sometimes used interchangeably with 'mixing desk' or 'mixer,' but in professional audio it specifically refers to the large-format device used for live and studio mixing, as opposed to a simple DJ mixer or a software mixer.
