Matrix

A facility found mostly in live-sound mixing consoles used to create separate mixes which can be sent to many different output destinations. Essentially, a Matrix creates 'a mix of mixes' since derived from pre-mixed output signals such as subgroups, auxes or main outputs. This is in contrast to the normal console mixing facilities which are derived from input channel signals. A matrix can be any size, and is usually described in terms of numbers of inputs and outputs, such as 2x2 or 8x8, or 8x6 etc with a level control at each junction of the matrix so that the desired amount of any source can be sent to any output - and it is this feature that makes a Matrix more versatile than a conventional subgrouping system. Matrix sends might be used to create appropriate feeds for disparate destinations like PA front fills, green-room foldback, camera recorders, and so on.
