Intoducing the WMD Triple Bipolar VCA! Featuring 3 bipolar VCAs, a MIX out, and more,this module provides dedicated inverting/polarizing/bipolar amplitude modulating inputs normaled to the Phase Modulation inputs on the PDO and can connect to it as an expander but is fully functional on it's own!
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 and can be used to great effect on VCOs and LFOs.
The Triple Bipolar VCA also has a special feature-dedicated inputs on each channel allow for replacing the inverted signal with a seperate input! When the VCA goes negative, rather than outputing the inverted +input it will alternate to the -input if patched, sort of like a crossfader only instead of the sum in the middle, it will be silence.
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
- Excellent for Bipolar modulation or AM synthesis
- Essential expander for the PDO mkII
- Linear Response VCAs
- Bipolar Attenuators for CV control
- Mix Output Sums All Three VCAs
- Bi-color Signal LEDs
- "-" Input for Mix Through Zero, converts a bipolar vca channel to a dual vca
- Skiffable PCB Design

Note: This is a used item, and while it is guaranteed to be fully functional it is almost sure to also contain "rack rash" on the mounting holes and have some minor scratches on the panel from use. It will include a ribbon cable, m3 screws, and a box, but not the original box.
