Studio Electronics SEM Modulāra sistēma

The Studio Electronics Boomstar Modular SEM Filter is a voltage controlled state variable filter providing simultaneous high pass, low pass, and band pass outputs, with a 12 dB/oct slope. The SEM is known as a 'Voltage Controlled State Variable Filter' because it provides simultaneous high pass, low pass, and band pass outputs, all with a 12 dB/oct slope. This version is a combination of the original SEM filter and the newer design from the OBX, along with improvements by Studio Electronics. It has a modest current draw, which it pulls evenly from the plus and minus rails. Three attenuverter and four attenuation pots control the FREQUENCY, RESONANCE, FREQ CV 1, RESO CV, LP HP, INPUT and OUTPUT, delivering smooth, detailed, and complex expression.
