IF YOU ARE LOOKING FOR A UNIQUE AND POWERFUL PALETTE OF TONE COLORS, OR LOOKING TO GET A MORE ORGANIC SOUND, WE AT C.M.S. BELIEVE A RESONANT FIXED FILTER BANK IS A CRUCIAL NECESSITY. THE NEW 9012 FIXED FILTER BANK MODULE FROM C.M.S. IS A HIGH PERFORMANCE CIRCUIT MAINLY USED FOR WAVESHAPING, FORMANT MANIPULATION, COMB FILTERING AS WELL AS EQUALIZATION. MANY UNIQUE AND POWERFUL TEXTURES CAN BE OBTAINED BY PLACING THE 9012D AT VARIOUS POINTS IN A SIGNAL FLOW.
ENHANCING THE SIGNAL HARMONICALLY BEFORE VOLTAGE CONTROLLED FILTERING CAN PRODUCE SOME AMAZINGLY RICH AND VARIED TONE COLORS. CONVERSELY, HARMONIC ENHANCEMENT AFTER FILTERING ALSO HAS NUMEROUS TONAL POSSIBILITIES. THE SAME CAN BE SAID FOR RING MODULATORS, PHASE SHIFTERS ETC. MAKING THE POSSIBILITIES ENDLESS. THE 9012 IS ALSO USEFUL AS AN OUTPUT SIGNAL CONDITIONER OR GRAPHIC EQ. THE SEPARATE OUTPUTS ARE USEFUL FOR SELECTIVE FILTERING OR SPLITTING DIFFERENT BANDS INTO SEPARATE STEREO FIELDS. THE C.M.S. 9015 10 INPUT STEREO MIXER IS DESIGNED WITH THIS PURPOSE IN MIND (SEE NEXT PAGE). THE 9012 HAS 2 MODES. WHEN IN FIXED FILTER MODE THE UNIT OPERATION IS SIMILAR TO A GRAPHIC EQUALIZER. ALL 10 BANDS HAVING THE SAME PHASE RELATIONSHIP. WHEN THE MODE SWITCH IS SET TO "COMB FILTER" EVERY OTHER FREQUENCY BAND IS INVERTED. THIS CONFIGURATION PRODUCES EVENLY SPACED, NOTCHES IN THE FREQUENCY SPECTRUM, HENCE THE NAME - COMB FILTER. THIS EFFECT PRODUCES SOME VERY UNIQUE TONES. IN ADDITION, THERE IS A MIX CONTROL PROVIDED THAT VARIES THE OUTPUT FROM "DRY TO "WET" ENABLING EVEN MORE PHASE COMBINATIONS DUE TO THE INTERACTION BETWEEN THE ORIGINAL SIGNAL AND THE FILTERED SIGNAL. PLEASE NOTE: DUE TO THE COMPLEX NATURE OF THIS MODULE, IT IS NOT PURELY DISCRETE. IT IS A HYBRID MEANING IT USES A COMBINATION OF MATCHED TRANSISTORS AND HIGH SLEW RATE, LOW NOISE INTEGRATED CIRCUITS.
