The current CS 8 ol series determines generally products which are realized in a so called open loop design These are electronic circuits working without high amplification amplifiers and then stabilizing and linearizing feedback loops In earlier times 1970s years these technique were widely used Typical sound properties are featured by warmth and creaminess In this manual the first two products will be described namely the voltage controlled filters HDH6 and VDL6 HDH6 stands for Horizontal Diode High pass with 6 poles in the transfer function which means a maximum slope of 36 db octave Accordingly to this VDL6 stands for Vertical Diode Low pass with also a slope of 36 db octave Each of these filters is contructed as a true dual filter containing two identical and independent filters A and B Each filter A and B provides 4 simultaneous outputs with different slopes which are clearly different in sound By mixing and or subtracting and or sharing of the overall 8 outputs one obtain mighty musical creative possibilities The module is designed with a width of 19 PU part units 1 PU 5 08mm for installation into a 3 HU height units modular rack with a built in 12 V power supply Furthermore the module is equipped with CV Control Voltage inputs for cutoff frequency FREQ and resonance RESO separately for each channel that true and independent dual stereo audio operating is possible Design and implementation me
