Description

The ACL VC Dual Amp holds two identical, fully discrete linear VCAs, built on an entirely new circuit derived from the precise measurement circuits of oscilloscopes and adapted for gain control by an external CV, so they amplify without colouration, distortion or bleed.

Key features

  • A GAIN knob for manual control and a CV attenuator scaling the CV input on each VCA
  • Audio and CV inputs of VCA 1 normalised to VCA 2, for easy voltage-controlled crossfades and stereo panning when both share the same signal
  • A MIX section with an AUX input and a SUM output
  • DC-coupled throughout, so it processes control voltages as well as audio
