Cwejman RM-2S Stereo-Ringmodulator


Module is not in production anymore

High-end stereo ring modulator with integrated phase shifted carrier oscillators. You can use it as a stereo device or as two mono ring modulators.



Two separately usable ringmodulators are connected to each other in an intelligent way over the "quadrature" carrier generator in this module.
Switchable from LFO to audio range the Oscillator generates a Sine as carrier signal for the ringmodulator A (CG A) that is used in the ringmod B with 90 degrees delay (CG B), what is offering diverse complex effects in addition.
The frequency is controlled over knobs coarse and fine and over CV in addition as also the level of both ringmod units. The left input is routed to the right one as long as there is nothing patched.

Frequency range from 0,01Hz bis 20 kHz, Sinewave with 0,1% THD and second take with 90 degrees delay. Maximum input/output 12V p-p.


Audio In: 4 x 3,5mm jack
Audio Out: 4 x 3,5mm jack (2 for oscillator out)
CV-In: 3 x 3,5mm jack
