The kHs Ring Mod uses either an internal sine/noise generator or a secondary input as the second signal in the modulation, and allows for versatile transformation of the modulating signal.

Bias knob - Amount of positive bias to add to the secondary input.
Rectify knob - Amount of positive or negative rectification to apply to the secondary input.
Frequency knob - The base frequency of the internal oscillator or filter cutoff for the internal noise generator.
Spread knob - Shifts the frequency of the internal generator slightly for left and right channels to achieve a stereo effect.
Modulator - Selects the secondary input.
Mix knob - The dry/wet mix of this effect. A lower value will let some of the unmodified signal through.
