The Kobolt is a 16-channel mixer, with each channel having its own volume and panning controls. A single Kobolt mixer could be used in your track to input all of your devices or many could be used. You could apply effects to your devices before they are plugged into the Kobolt or an effect could be applied to the kobolt itself, meaning that any device plugged into the Kobolt would go through the effect pedal and have the effect applied to it. If you would be using a Kobolt as your main mixer its output would be plugged into the input for the master output.
