The u3A is a three channel attenuverter – useful for scaling, adding offset, inverting or summing signals. Each input is normalled to +5V, so with nothing plugged into the input jacks, each knob will control a voltage range from -5V to +5V. Each output is also summed to the adjacent channel on the right when no cable is connected.
