EM-302 | Four-Quadrant Multiplier / Balanced Modulator
RINGO is a compact, fully analog four-quadrant multiplier designed for balanced modulation, complex spectral transformation, and continuous voltage-domain computation.
At its core, RINGO performs true analog multiplication between Program and Carrier signals, generating sum-and-difference frequencies, metallic sidebands, and evolving harmonic structures. Independent bipolar attenuverters provide precise control over signal amplitude and polarity, while the G-Variable introduces an adjustable bias for shifting the multiplier's operating point.
Selectable AC/DC coupling extends its functionality beyond conventional ring modulation. In AC mode, RINGO produces classic balanced modulation effects, from subtle tremolo-like interactions to dense, inharmonic textures. In DC mode, it operates as an analog computation processor, enabling bipolar VCA operation, voltage-controlled inversion, and signal multiplication across the audio and control-voltage domains.
Illuminated Σ / Δ indicators reference the sum-and-difference relationships fundamental to balanced modulation.
