WMD Triple Bipolar VCA Eurorack Module (Silver)

WMD Triple Bipolar VCA Eurorack Module (Silver)

Sorry, this item is out of stock.

Intoducing the WMD Triple Bipolar VCA, the input side expansion for our Phase Displacement Oscillator. This module provides dedicated inverting/polarizing/bipolar amplitude modulating inputs normaled to the Phase Modulation inputs on the PDO.

A bipolar VCA is like a normal VCA when operated with positive control voltage. But when using a negative control voltage, the output will swing back through zero amplitude and the output will be inverted. This produces deeper modulation than a normal VCA.

The Triple Bipolar VCA is also designed to be used as a standalone module, it does not require the PDO to operate.
