Sopot from XAOC Devices is a compact unity-gain mixer with twelve inputs and three outputs. In the main, Sopot consists of three similar mixer units, each with four inputs and one output. The middle mixer can be mixed to the other two units Mix L/R in a 50%/off/100% level ratio via a toggle switch. With three jumpers on the back the attenuation can be defined between Unity Gain (1:1) and -12dB (1:4). Since the module is equipped without its own controls for level control, it is primarily suitable for mixing drum and synthvoice modules, which often have their own volume control.
