SHMIX is a 6 channel DC mono mixer with separate input attenuator knobs for each channel. The mix output has a separate master level knob. The mix can also be levelshifted by the shift knob and sent to a separate shift output.
All knobs are linear.
On the backside there are pin strips for all inputs and outputs. These pins are connected when no cables are attached to the jacks. If you insert a cable in a jack, then the connection to the pin on the backside is broken. This can be used to have the normal functions connected on the backside and hide some cables in the front. You can also chain multiple SHMIXes together with the pins on the backside.
