Ringshifter<br />
The Ringshifter effect combines a ring modulator with a frequ<strong>en</strong>cy shifter effect. Both<br />
effects were popular during the 1970s, and are curr<strong>en</strong>tly experi<strong>en</strong>cing something of a<br />
r<strong>en</strong>aissance.<br />
The ring modulator modulates the amplitude of the input signal using either the internal<br />
oscillator or a side-chain signal. The frequ<strong>en</strong>cy spectrum of the resulting effect signal<br />
equals the sum and differ<strong>en</strong>ce of the frequ<strong>en</strong>cy cont<strong>en</strong>t in the two original signals. Its<br />
sound is oft<strong>en</strong> described as metallic or clangorous. The ring modulator was used ext<strong>en</strong>sively<br />
on jazz rock and fusion records in the early 1970s.<br />
The frequ<strong>en</strong>cy shifter moves the frequ<strong>en</strong>cy cont<strong>en</strong>t of the input signal by a fixed amount<br />
and, in doing so, alters the frequ<strong>en</strong>cy relationship of the original harmonics. The resulting<br />
sounds range from sweet and spacious phasing effects to strange robotic timbres.<br />
Note: Frequ<strong>en</strong>cy shifting should not be confused with pitch shifting. Pitch shifting<br />
transposes the original signal, leaving its harmonic frequ<strong>en</strong>cy relationship intact.<br />
Getting to Know the Ringshifter Interface<br />

• Mode buttons: Determine whether the Ringshifter operates as a frequ<strong>en</strong>cy shifter or as<br />
a ring modulator. See Setting the Ringshifter Mode.<br />
• Oscillator parameters: Use these to configure the internal sine wave oscillator, which<br />
modulates the amplitude of the input signal—in both frequ<strong>en</strong>cy shifter modes and<br />
the ring modulator OSC mode. See Using the Ringshifter’s Oscillator.
