A-133-2 Dual VC Polarizer

Doepfer A-133-2

Doepfer's A-133-2 is a two-channel voltage controllable polarizer, acting as a VCA, ring mod, or attenuverter for your system. Each channel features a manual level control (from -1x to 1x gain), a CV input with dedicated attenuator, and two identical signal outputs. A-133-2 can act as a simple voltage scaling utility, a ring modulator, or a VCA—or two of these at once. If you're looking to add an enormous amount of utility in a small space, the A-133-2 is a great way of adding nuance and vast new sonic options to your Eurorack modular synthesizer.
