| ====Auxiliary==== | ====Auxiliary==== | ||
| - | Aux for short, an additional output on a sound desk into which any channel can be sent in addition to the main output. A "post fade" aux for a particular channel means the level at which the channel is sent to the aux depends on the level of the fader (usually the level at which it is also sent to the main output), and a "pre fade" aux allows the level sent to the aux to be independent from the level of the fader. Pre fade aux's are usually used for foldback and additional speakers, and pre fade is usually used to send to effects processors. | + | Aux for short, an additional output on a sound desk into which any channel can be sent in addition to the main output.
