WMD Triple Bipolar VCA

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.

Features:

• Three Bipolar VCAs
• Normaling to PDO
• Linear Response
• Bipolar Attenuator for CV
• Mix Output Sums All Three VCAs
• Bi-color Signal LEDs
• “-” Input for Mix Through Zero
• Skiffable PCB Design
• 8 HP
• +80mA/-75mA Current Consumption

Other Notable Things

The Triple Bipolar VCA is 8HP.

Current consumption is 80mA for the +12 rail; 75mA for the -12 rail.

The depth from the back of the panel is roughly 25mm.
