A-133 Dual VC Polarizer

61,2 €


Two voltage controllable amplifiers which can amplify positively or inverted. As this module is a somewhat different VCA you can use it for AM sounds or even as a ring modulator!


  • Module A-133 is a special dual voltage controlled amplifier that enables both positive and negative amplifications.
  • The main application of the module is the processing of control voltages, e.g. ADSR or LFO. The amplification range is about -2.5....0....+2.5.
  • Amplification can be adjusted manually (Man control) and by an external control voltage with attenuator (CV).
  • The present amplification is displayed with two LEDs: one for positive and one for negative amplifications.
