post fader Sends in analog mixers are positioned either before (pre) or after (post) the
fader. Post fader means positioned after the fader in the signal flow, with the level of a
signal going to the Send changing along with the fader movements.
pre fader Sends in analog mixers are positioned either before (pre) or after (post) the
fader. Pre fader means positioned before the fader in the signal flow, so the level of a
signal routed pre fader to a Send remains constant, regardless of any fader movements.
