Modes
The four mode buttons determine whether the Ringshifter operates as a frequency
shifter or as a ring modulator.
 Single (Frequency Shifter) button: The frequency shifter generates a single, shifted
effect signal. The oscillator Frequency control determines whether the signal is
shifted up (positive value) or down (negative value).
 Dual (Frequency Shifter) button: The frequency shifting process produces one shifted
effect signal for each stereo channel—one is shifted up, the other is shifted down.
The oscillator Frequency control determines the shift direction in the left versus the
right channel.
 OSC (Ring Modulator) button: The ring modulator uses the internal sine wave
oscillator to modulate the input signal.
 Side Chain (Ring Modulator) button: The ring modulator modulates the amplitude of
the input signal with the audio signal assigned via the side chain input. The sine
wave oscillator is switched off, and the Frequency controls are not accessible when
Side Chain mode is active.
The Oscillator
In both frequency shifter modes, and the ring modulator OSC mode, the internal sine
wave oscillator is used to modulate the amplitude of the input signal. The Frequency
control sets the frequency of the sine wave oscillator.
 In the frequency shifter modes, this parameter controls the amount of frequency
shifting (up and/or down) applied to the input signal.
 In the ring modulator OSC mode, this parameter controls the frequency content
(timbre) of the resulting effect. This timbre can range from subtle tremolo effects to
clangorous metallic sounds.
