24DB ARP 2500 Ladder Filter

THE CMS 1066 IS AN EXACT REPRODUCTION OF THE FILTER SECTION OF THE ARP 1006 FILT-AMP MODULE WITHOUT THE VCA. IT IS ARPs VERSION OF THE TRANSISTOR LADDER. THE CIRCUIT FEATURES AN ALL BIPOLAR SIGNAL PATH PRODUCING A WARMER SOUNDING FREQUENCY CURVE COMPARED TO THE ARP 2600 FILTER. THE FACT THAT ARP CHOSE TO PERMANENTLY PATCH THE VCF TO THE VCA IN THE ORIGINAL 1006 MODULES WAS "DIFFERENT" BUT LIMITING IN OUR OPINION, SO WE CHOSE TO SEPARATE THE 2 FUNCTIONS IN KEEPING WITH THE DEFINITION OF A TRUE MODULAR SYSTEM.

THE UPDATED CMS 1066 MODULE FEATURES A 5 INPUT PRECISION AUDIO MIXER. 4 OF THE INPUTS HAVE ATTENUATORS AND THE 5TH INPUT IS AT FULL STRENGTH SO YOU CAN PATCH ADDITIONAL MIXERS ETC. INTO THE AUDIO INPUT.

THE 1066 ALSO HAS THE CMS RESONANCE MODE SWITCH. THIS FEATURE CHANGES THE RESONANCE FUNCTION SO THAT AS THE RESONANCE IS INCREASED THE OVERALL VOLUME DOES NOT DECREASE LIKE MOST LADDER FILTERS. THIS PRODUCES A MORE POWERFUL RESONANCE RESPONSE. IT ALSO INCREASES THE SIGNAL TO NOISE RATIO FOR SETTINGS WITH HIGH RESONANCE.
