|With a postfade
aux send, the signal is sent to the aux
send master in proportion to the level of
the input fader.
This is the most common way to send a signal to an external processor such
as a reverb. As the signal is sent to the master output, it also
appears in the reverb field. As the signal fades, it will also fade in
the reverb. Although not as flexible as prefade
sends, postfade sends allow the user to maintain a consistent relationship
between dry (original) and wet (processed) signals and it is ideal for
mixing: no aux send knobs to fade up and down as well.
