Six-way mixer in 6HP. Cannot get much simpler than this.
The first output is normalled into the second stage, so when nothing is patched into this jack the module behaves as a 6x1 mixer. Using both outputs simultaneously will give separate 3x2 mixers - this can be used as a little performance effect on its own.
When linear taper potentiometers are used, the additional placeholder resistors can be used to turn the taper log-like (if desired).
