THE C.M.S. 9010 VOLTAGE CONTROLLED PHASE SHIFTER UTILIZES A DISCRETE 14 STAGE VOLTAGE CONTROLLED ALL PASS PHASE SHIFT NETWORK TO ACHIEVE DRAMATIC RESONANT PHASING EFFECTS, COMB FILTERING, HASS EFFECTS, TUNED NOISE AND CHORUSING.

MULTIPLE MODULATION INPUTS ARE AVAILABLE WITH THEIR RESPECTIVE ATTENUATORS INCLUDING AN ACCURATE 1V PER OCTAVE INPUT NORMALLED TO THE KEYBOARD BUSS. STARTLING TEXTURES ARE OBTAINED WHEN THE 9010 IS USED AS A RESONATOR THAT TRACKS THE KEYBOARD. THIS IS ALSO VERY EFFECTIVE FOR TUNED NOISE ETC. THERE IS ONE AUDIO INPUT JACK WITH ATTENUATOR. THE 3 MULTIPLE OUTPUTS COUPLED WITH THE PHASE SWITCH YIELDS NUMEROUS TONAL VARIATIONS. THE 9010 HAS A RESONANCE CONTROL AND WILL SELF OSCILLATE WHEN SET TO MAXIMUM. A SPECIAL INTEGRATED SERVO EXPANDER / COMPRESSOR CIRCUIT KEEPS NOISE AT A MINIMUM WHILE MAINTAINING DYNAMIC RANGE.

THE INTEGRATED VOLTAGE CONTROLLED LFO HAS DUAL SINE OUTPUTS 180 DEGREES OUT OF PHASE, ONE OF WHICH IS NORMALLED TO ONE OF THE MODULATION INPUTS OF THE PHASE SHIFT NETWORK. THE LFO ALSO HAS AN EXTERNAL VOLTAGE CONTROL INPUT JACK WITH IT'S RESPECTIVE ATTENUATOR. THE VOLTAGE CONTROLLED LFO IS ALSO EQUIPPED WITH A FREQUENCY RANGE SWITCH.
