A compact module full of character. The Doepfer A-133-2 VCA/Polarizer/Inverter/Ring Modulator slims down the popular A-133 module whilst adding new features and improvements.
Thanks to the range of features offered by the A-133-2, the module can be used in a variety of applications. Operate the module as a simple VCA, a voltage-controlled polarizer/attuverter, or a voltage-controlled inverter up to a DC coupled ring modulator. To provide this, the module contains two VCAs that allow both positive and negative amplification.
Overall amplification is defined by the sum of the voltage generated by the 'Man' control, the external control voltage CV and the position of the CV control which works as an attenuator for the external control voltage. The CV signal can also be modulated via the modulation control input ‘Mod’ with another control voltage.
