The RK3 Ringer / Shaper comes equipped with an audio input plus level potentiometer. Hot signals lead to fierce distortion. The Pulser’s behavior can be adjusted via the tune knob. Its results depend strongly on the incoming audio material, ranging from the sporadic addition of sound elements to a strange, rough sounding “resonance”. A CV / carrier input with attenuator sends signals to the screen grid of the 14B11 pentode. By applying an audio signal instead of control voltages, the user is able to generate primitive ring modulator effects. The audio output features another level potentiometer.
