WMD Triple Bipolar VCA: Flexible Signal Manipulation and Ring Modulation

The WMD Triple Bipolar VCA provides three independent channels of high-quality, DC-coupled amplification within a compact 8HP module. Unlike a standard VCA, a bipolar VCA (also known as a four-quadrant multiplier) can both amplify and invert the incoming signal based on the polarity of the control voltage. This makes the module exceptionally well-suited for ring modulation effects, complex AM synthesis, and precise scaling of control voltages. Built to WMD’s exacting standards, this module is an essential utility for any modular system. Please note: This item is available in limited supply only.
