A matrix mixer is an audio electronic device that directs multiple audio input signals to multiple outputs. It typically uses a level control such as a potentiometer to determine how much of each input will each output, and it can combine a simple on/off task switch. The number of individual controls is at least the number of inputs multiplied by the number of outputs.
Matrix mixers can be incorporated into larger devices such as mixing consoles or they may be standalone products. They always have routing and level control and may also include other features. Matrix mixers are often used in complex listening rooms to send audio signals to different loudspeaker zones. They can be used to give different mixed producers or directors of mixing projects to television, movies or recording studios.

Basics
In professional audio, the matrix mixer is used to direct audio signals from multiple sources to different destinations. These may be stand-alone devices or embedded in other larger products such as mixing consoles, digital audio workstations or digital signal processors.
The analog matrix mixer contains a number of simple electronic mixer circuits, the quantity is the number of inputs multiplied by the number of outputs. Each electronic mixer controls the gain level from one input to an output. Level control is usually a rotating potentiometer (called a "pot"). Each line of the electronic stirrer circuit, one of each input, feeds the sum or combines the amp at the output. A fader (a linear potentiometer) can be used to control the level of each output signal. Other controls may include the mute button for each input/output junction, the mute button for each input, the mute button for each output, and a button that reverses the polarity of the input signal. The output signal from the matrix mixer may be digital, or they may be analog balanced or unbalanced. It is possible in a matrix mixer to combine an all-analog signal path with a digital level control.
Any audio console that does not have a matrix section can be connected to an external matrix mixer. Many audio manufacturers have produced matrices that incorporate digital signal processing (DSP) that offer additional tools such as compression, equalization, evasion, gating, and loudspeaker system management. DSP-based matrix systems can be optimized by audio engineers who are then made inaccessible by inexperienced voice board operators.

In direct sound mixing, the home mixing console often includes a matrix mixer section to optimize the sound mix to various locations in the show room. Subgroups, additional mixtures, submixes or even main output are routed through the matrix mixer to different loudspeaker zones, making the matrix essentially "mixed mix". A front-of-house matrix can be used in concert to switch between mixing console from headliner and opening act. Matrix mixer features can be included on analog or digital console. For example, console console console Midas Console XL4 has 8 8 sub-groups of 8 matrices to add subgroups to 8 matrix outputs; the same basic module is available separately as Midas XL88 (see photo). Yamaha M7CL digital mixing console is another product; it has a matrix section of 19ÃÆ'-8 sum of 16 mixes as well as the left/right/main mono output (see screenshot). In a classical analogue analog mixer without a fader, the console is set as a large matrix mixer with the addition of an equivalent filter and other controls for each input.
The matrix mixer is useful for performance spaces with multiple loudspeaker zones such as the left and right main loudspeaker arrays, cluster or array loudspeaker centers, under-balcony speakers for the rear seating area, front seat lips loudspeakers, overflow spaces, green spaces, foyer , and live broadcast or stream to a distant audience. If there is no separate mixer monitor with its own operator, the matrix mixer can be used to send a different mix to a stage monitor or sidefill loudspeaker. However, the use of such a matrix is ​​limited by the possibility that the musicians on stage will be distracted by any changes made at the channel level by the front-of-house operator. It is usually better to provide a stage monitor with signals obtained from the pre-fader auxiliary send. Listeners outside of the main performance space will not hear reinforced instruments such as electric guitars or those inside them, so the output matrix that leads to their location will usually contain more reinforced instruments. Also, matrices can be used to send different mixes to any recording device, especially blends that are optimized for stereo playback while direct sound for performance space can be presented in mono. The matrix mixer can be used to combine the main mix with the audience atmosphere microphone to get a more "live" mixture for the mixed recording.

In the mixing process for a film or television, the matrix mixer can be used to give a film director, television director or producer a mixture of work from a project while a mixed engineer puts it together. In the recording studio, the same method can be used to give the producer a different mix of recording during the mixing process. In addition, the matrix mixer may have been used to route various audio input channels to a specific recording channel.
