{"product_id":"tangible-waves-2vca","title":"Tangible Waves - 2VCA R2","description":"\u003cp\u003e2VCA contains two separate VCA (voltage controlled amplifiers); the classic module to shape the volume of a sound that is fed to IN by a control voltage, e.g. from an ENV to the CV input. If zero voltage is provided, the VCA stays closed and the IN signal doesn't go through. As the CV rises so does the signal strength going through to the output.\u003c\/p\u003e\n\u003cp\u003eA switch determines the operation mode (DC\/CV or audio), choosing the right position can reduce\/avoid pop's with short attack envelopes.\u003c\/p\u003e\n\u003cp\u003eAn additional knob for each VCA attenuates the level, if necessary.\u003c\/p\u003e\n\u003cp\u003eModule power consumption: 5 mA\u003c\/p\u003e\n\u003cp\u003eThere is also a 4VCA module available.\u003c\/p\u003e\n\u003cp\u003eInputs\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003e\u003cstrong\u003eIN1\u003c\/strong\u003e\u003c\/b\u003e - accept audio or control signal to be amplified or attenuated\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e\u003cstrong\u003eCV1\u003c\/strong\u003e\u003c\/b\u003e - accept CV for amplitude modulation of IN1 signal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e\u003cstrong\u003eIN2\u003c\/strong\u003e\u003c\/b\u003e - accept audio or control signal to be amplified or attenuated\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e\u003cstrong\u003eCV2\u003c\/strong\u003e\u003c\/b\u003e - accept CV for amplitude modulation of IN2 signal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOutputs\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003e\u003cstrong\u003eOUT 1\u003c\/strong\u003e\u003c\/b\u003e (2) - amplified or attenuated signal from IN1\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e\u003cstrong\u003eOUT 2\u003c\/strong\u003e\u003c\/b\u003e (2) - amplified or attenuated signal from IN2\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e\u003cstrong\u003eBUS CV\u003c\/strong\u003e\u003c\/b\u003e - CV signal from MIDI\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e\u003cstrong\u003eBUS CTRL\u003c\/strong\u003e\u003c\/b\u003e - CTRL signal from MIDI (CH1 - CC20)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e\u003cstrong\u003eMULT\u003c\/strong\u003e\u003c\/b\u003e - Passive signal multiplier, all sockets are bi-directional\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eControls\u003c\/p\u003e\n\u003cp\u003eThe controls are grouped into 2 identical groups marked with the number 1 and 2 for each of the individual VCA.

They can be used to modulate any signal's amplitude, be it control or audio rate. Here are some ideas:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePatching an audio signal both into the IN and the CV inputs results in AM synthesis.\u003c\/li\u003e\n\u003cli\u003ePatching separate audio signals to VCAs\/CV through a mixer you get a wave shaper.\u003c\/li\u003e\n\u003cli\u003ePatch an LFO to IN1 and another LFO to CV1. The second LFO then modulates the amplitude of the first one, providing some variety to it.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eVCAs are simple and absolutely versatile. That's why \"you can never have too many VCAs\".\u003c\/p\u003e","brand":"Tangible Waves","offers":[{"title":"Default Title","offer_id":37640343290026,"sku":"","price":43.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0020\/5199\/7743\/files\/2vca_0020a62c-ad48-4a58-91fd-6ceb5ed9faed.jpg?v=1768679882","url":"https:\/\/www.noisebug.live\/products\/tangible-waves-2vca","provider":"Noisebug","version":"1.0","type":"link"}
