DoepferA-133 Dual Voltage Controlled Polarizer

Doepfer A-133

The A-133 from Doepfer allows for two channels of voltage-controlled attenuation over an input signal. This can be interesting when used with CV signals such as envelopes and LFOs, but can also be used to achieve waveshaping and ring-modulation-like effects when used with audio signals. Each channel features an attenuator for the modulation CV as well as a manual attenuator for the "carrier" signal.

A-133 Features

• Dual voltage-controlled polarizer module
• Attenuverter for control CV with LED indicator per channel
• Manual attenuverter for input signal
