The Doepfer A-133-2 VCA/Polarizer/Inverter/Ring Modulator is a compact module that offers a range of features for a variety of applications. With two VCAs, the module allows for positive and negative amplification, and can be used as a simple VCA, a voltage-controlled polarizer/attenuverter, or a voltage-controlled inverter. The module also includes a DC-coupled ring modulator with an offset feature, and the overall amplification is defined by the Man control, external control voltage CV, and the position of the CV control. The CV signal can be modulated via the modulation control input Mod with another control voltage. This streamlined version of the A-133 module has added features and specifications including a width of 4HP and product code A-133-2.
Doepfer A-133-2 VCA/Polarizer/Inverter/Ring Modulator
- Multi-functional module: The A-133-2 is a compact module that offers a range of features, making it suitable for a variety of applications. It can be used as a VCA, a voltage-controlled polarizer/attuverter, a voltage-controlled inverter, and a DC-coupled ring modulator with an offset feature.
- Two VCAs: The module contains two voltage-controlled amplifiers (VCAs) that allow for both positive and negative amplification. This provides a greater range of control over the output signal.
- Voltage-controlled polarizer/attenuator: The A-133-2 can be used as a voltage-controlled polarizer/attenuator, allowing the user to attenuate or invert the input signal. The 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.
- DC-coupled ring modulator: The module features a DC-coupled ring modulator with an offset feature, allowing the user to create complex and interesting sounds by mixing two input signals.
- Streamlined design: The A-133-2 is a streamlined version of the popular A-133 module, featuring added features and improvements while maintaining a compact form factor of only 4 HP.
