This is probably the most well-designed Nexus product I’ve come across since the eye-catching Nexus Multifunc! The product looks sharp, and everything is user friendly to the max! Let me familiarize you with the product. It is meant to control three fans via three-pin connections, and two cathodes via an onboard inverter. The two cathodes are coupled to one control knob with three settings; off, on, and sound activated.
