Description

Doepfer's two voltage-controlled polarizers in 4 HP: each amplifies a signal by anything from -1 to +1, as a VCA, an attenuverter, an inverter or a DC-coupled ring modulator.

Key features

  • Two channels, each with a manual gain control from -1 (inverted) through 0 to +1
  • A CV input per channel with its own attenuator
  • A Mod input per channel modulates the CV itself; it is normalled to +5 V
  • A two-colour LED per channel shows the gain: yellow positive, red negative
  • DC coupled, for audio and control voltages alike
