WE'RE TAKING THINGS UP ONE MORE NOTCH, HERE AT C.M.S. WITH THE INTRODUCTION OF OUR NEW LINE OF PURELY DISCRETE SYNTHESIZER MODULES.

C.M.S. MODULE 9007 CONTAINS TWO PROFESSIONAL VOLTAGE CONTROLLED AMPLIFIERS DESIGNED FOR USE IN THE C.M.S. MODULAR SYSTEM. THESE UNITS EXHIBIT LOW DISTORTION AND FULL FREQUENCY RESPONSE FROM DC CONTROL VOLTAGES TO 40KHz. THE 9007'S VOLTAGE CONTROLLED AMPLIFIERS UTILIZE C.M.S.'S NEW 4088 DISCRETE HIGH FIDELITY SUBMODULES RESULTING IN AN EXTREMELY QUIET, RESPONSIVE AND TRANSPARENT VCA. OUR EXTENSIVE RESEARCH INTO DISCRETE AMPLIFIER DESIGNS SUCH AS API, NEVE, MOOG AND JENSEN RESULTED IN A NEW LINE OF AURALLY DISTINCTIVE DISCRETE SUBMODULES.

EACH VCA HAS TWO ATTENUATED INPUTS, INVERTING AND NON INVERTING, THAT WILL ACCEPT BOTH AUDIO AND CONTROL VOLTAGES FOR AMPLITUDE PROCESSING. THE VCA ALSO HAS SEPARATE, VARIABLE LINEAR AND EXPONENTIAL CONTROL INPUTS AVAILABLE SIMULTANEOUSLY. A LED CONTROL MONITOR PROVIDES VISUAL FEEDBACK ON EACH CONTROL LEVEL THIS ENABLES THE PRECISE MIXING OF 2 ENVELOPES AND IS ESPECIALLY USEFUL FOR PERCUSSIVE, PUNCHY ENVELOPES. AN "INITIAL GAIN" CONTROL ADJUSTS THE AMPLITUDE DIRECTLY FROM THE FRONT PANEL. THE UPPER VCA HAS AN INTEGRATED INVERTER SWITCH THAT INVERTS THE LINEAR CONTROL. EACH VCA IS SUPPLIED WITH TWO 1/8TH INCH HIGH LEVEL OUTS AND ONE 1/4 INCH LINE LEVEL OUT.
