The four channels are organized in two sections, A and B, each consisting of two inputs between which you can crossfade manually with the Blend controls. Each section has an own direct mix output: 1+2 and 3+4 which means you can use A and B sections as two individual 2-channel mixers.
Sections A and B are then sent into the voltage controlled X-Fade section. Using Output A/B you get a mix of both sections and i nfact a four-channel mixer with some voltage control.
Besides this the X-Fader features two sockets FADE A and FADE B which are used to inject external signals instead of the A or B section. This makes it posible to use the voltage controlled corssfader independently of the mixing possibilites of A and B sections. Pretty versatile.
A section: In 1, In 2, Out 1+2
B section: In 3, In 4, Out 3+4
X-Fade CV input, mix output A+B
external signal inputs Fade A and Fade B
