RM&S

Ring Modulator & Sub-Octave Generator

RM&S is a 4HP Ring Modulator and Sub-Octave generator. The Ring Modulator is an active, CMOS-based circuit adapted from the ARP Odyssey. Ring Mod is typically generated from inserting square wave VCOs to Input 1 & 2. But that shouldn't stop you from sending sawtooth, wavetables and noise sources through this. The Sub-Octave Generator circuit is derived from the SH-101 and provides -1 and -2 octaves from a square wave plugged into Input 1. Many VCOs put out varying degrees of signal amplitude, a trim pot is provided to attenuate aggressive input signals for the Sub-Octave Generator circuit. Output jacks include: Ring Mod, summed Ring Mod + Sub-1, Sub-1, and Sub-2. RM&S is an active-mode module that uses extremely low current.
