The Kommander does not ships with a 9V PSU.
The Kommander is a handheld dual infrared X-Y motion controller that makes controlling your electronic instruments intuitive and fun. The device measures the distance to other objects and sends out corresponding CV signals between 0 and 8 volts and a trigger with adjustable threshold. This will allow you to create complex synth sounds, trigger a drum machine, control your KOMA Field Kits or any other instrument that is capable of receiving CV / Gate signals.
The attenuators on the back panel allow you to attenuate the maximum voltage output, so you can e.g. set the range from 0V to 5V. Just plug the Kommander into your synthesizer and create!
