Post-fade

Definition

Post-fade auxiliary sends are used to send signals to effects processors.

The fact that the amount of signal going through a post-fade send is determined by the fader position gives the engineer greater control over the positioning of the sound. More fader level and less aux send will make the sound closer, while less fader level and more aux (auxiliary) send makes it sound further away.

This gives the mix engineer control over the front-to-back dimension of the music.
