channel. As the knob is turned counterclockwise (left), the amount of Mix A
increases, and the amount of Mix B decreases. As the knob is turned clockwise
(right), the amount of Mix A decreases, and the amount of Mix B increases. With
the Mix knob in the “12 o’clock position,” an equal amount of Mix A and Mix B is
sent to the channel’s headphones.

This is most commonly used as a type of “Solo” for the external stereo input.
