New Frequency Shifter

The Serge New Frequency Shifter is another astonishing (re)design by Serge, much improved over his original 1979 version. Actually it is a combination of two new Quadrature Oscillators plus two(!) Frequency Shifters, offering 5 different modes from separate use to true Stereo Processing.

New Quad Oscillator(s)

• 4 sinewave outputs
• Extremely wide frequency range: deep sub audio up to >16kHz
• Exceptional tracking over 6+ octaves (typically <1ct deviation)
• Temperature compensated
• Designed by Serge Tcherepnin in 2024

New Frequency Shifter(s)

• 2 independent Frequency Shifters
• External Mode: Right side modulates left
• True Stereo processing possible
• Designed by Serge Tcherepnin in 2024

The FREQUENCY SHIFTER does not transpose. Rather it shifts each harmonic of the signal by a fixed value equal to the shifting frequency. Thus, as the shifting frequency becomes larger, the relationships between overtones are altered, and timbres change dramatically.
