Description

Doepfer's dual voltage controlled crossfader in 4 HP: two identical units, each fading between two inputs.

Key features

  • Two crossfaders, each made of two VCAs with opposite control, mixed to one output
  • Symmetrical mode (about -2.5 V to +2.5 V, 50/50 at 0 V) or asymmetrical mode (0 to +5 V), chosen by an internal jumper
  • CV1 normalled to CV2, and In1B normalled to In2A (the arrows on the panel)
  • DC coupled: audio and control voltages alike
  • Can be modified to mix both outputs at Out 2
