An output from a mixering console that is connected to the input of an effects device. The effects send outputs usually have volume controls to set the effect send level, and the overall level of all the effects send outputs may be controlled by an effects master control operating from the effects bus. Effects sends (usually referred to in this case as aux sends) are typically used to feed effects processors such as reverbs, or are used to feed monitor systems, either speakers on stage or headphones in the studio. Whereas the main outputs of a mixer have a mix of everything that has a main fader turned up, the effects sends, with their own mix controls, have an independent mix. Effects sends are also used to feed the house mix to the PA system, when they are usually called post-fader sends. Also called an post-fader send, or aux (auxiliary) send. See insert send.
