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 usually 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 Roland 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 adjust input impedance of VCOs for the Sub-Octave Generator circuit.
Output jacks include: Ring Mod, summed Ring Mod + Sub-1, Sub-1, and Sub-2. The RM&S is hand-crafted in the USA.
Measured Current Draw: 2mA on -12V, 5mA on +12V, 5V not used
