Think of it as a reverse mult - whereas a mult will take a single input and duplicate it n times, this mixer takes n inputs and sums them together at a single output. The inputs and output are resistively coupled, so it'll handle both audio signals and control voltages.
As supplied, the mixer is set up to have unity gain (ie. what goes in, comes out) by default - if you want to alter the overall gain, there's a trimmer resistor on the rear of the board which will allow you to do this.
2HP wide - supplied with Euro-to-JST power connector
