This module provides dedicated inverting\/polarizing\/bipolar amplitude modulating inputs normaled to the Phase Modulation inputs on the PDO.\u003c\/p\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cp\u003eThe Triple Bipolar VCA is also designed to be used as a standalone module, it does not require the PDO to operate.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThree Bipolar VCAs\u003c\/li\u003e\n\u003cli\u003eNormaling to PDO\u003c\/li\u003e\n\u003cli\u003eLinear Response\u003c\/li\u003e\n\u003cli\u003eBipolar Attenuator for CV\u003c\/li\u003e\n\u003cli\u003eMix Output Sums All Three VCAs\u003c\/li\u003e\n\u003cli\u003eBi-color Signal LEDs\u003c\/li\u003e\n\u003cli\u003e\"-\" Input for Mix Through Zero\u003c\/li\u003e\n\u003cli\u003eSkiffable PCB Design\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca title=\"tbvca triple bipolar vca expansion guide pdo mkii mk2 phase displacement oscillator vco\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0977\/3366\/files\/PDOMK2ConnectionsGuide.pdf?1442570493784805961\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003ePDO EXPANSION CONNECTION GUIDE\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cdiv class=\"video-wrapper\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/Bd-AlzqI7Z8\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\" data-mce-fragment=\"1\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003ccenter\u003e\u003cstrong\u003eControls and I\/O\u003c\/strong\u003e\u003c\/center\u003e\n\u003ccenter\u003e\u003c\/center\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"boldgrey\"\u003e+ In\u003c\/span\u003e\u003c\/strong\u003e\u003cspan class=\"boldgrey\"\u003e \u003c\/span\u003e- This is the normal input for each VCA channel.

Normaled through this jack is the inverted signal from the + Input. Plugging in here converts the channel from a Bipolar VCA to a dual VCA. Negative control voltages will open the - side, and positive control voltages will open the + side. This allows you to use two modulation sources and alternate between them, while still retaining control over amplitude.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"boldgrey\"\u003eCV\u003c\/span\u003e\u003c\/strong\u003e - This input jack drives the CV knob.
