Description

Doepfer's second frequency shifter in 8 HP: it shifts every partial of a sound by the same amount in hertz, up and down at once, with a mix between the two.

Key features

  • Coarse and fine frequency controls, with a frequency CV input and attenuator
  • Mix control and CV input to blend the downward and upward shifted signals
  • Built-in squelch, driven by an envelope follower or left open, and an overload LED
  • Quadrature VCO outputs (sine and cosine), and inputs for an external quadrature VCO
  • Built-in VCA with external CV input
