The module is the \u003cstrong\u003elogarithmic form of the Doepfer A-130 module\u003c\/strong\u003e. For audio applications, an exponential VCA (A-130) is normally used, for control applications a logarithmic VCA (A-131). However, this is not a mandatory requirement. Each VCA has \u003cstrong\u003etwo audio inputs \u003c\/strong\u003ewith pre-amplifiers whose summed mix is amplified depending on the control voltages and the position of the gain control. The gain of the VCA determines the control voltages at the CV inputs and the position of the gain control, which is used to adjust the basic gain of the VCA. The module \u003cstrong\u003eis also suitable for processing slowly varying control signals \u003c\/strong\u003e(DC coupled inputs\/outputs).\u003c\/p\u003eDoepfer A-131 VCA log at a glance:\u003cul\u003e\n\u003cli\u003eLogarithmic VCA\u003c\/li\u003e\n\u003cli\u003eTwo inputs with attenuators\u003c\/li\u003e\n\u003cli\u003eCan be controlled via CV and manually\u003c\/li\u003e\n\u003cli\u003eAlso for slowly varying control signals\u003c\/li\u003e\n\u003c\/ul\u003eAdvantages:\u003cul\u003e\n\u003cli\u003eManufacturer:Doepfer\u003c\/li\u003e\n\u003cli\u003eTE \/ HP:8\u003c\/li\u003e\n\u003cli\u003eDepth (mm):45\u003c\/li\u003e\n\u003cli\u003e+ 12 V (mA):20\u003c\/li\u003e\n\u003cli\u003e- 12 V (mA):10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Doepfer","offers":[{"title":"Default Title","offer_id":58445763969356,"sku":"43842","price":75.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0769\/9854\/1644\/files\/doepfer-a-131-voltage-controlled-amp-vca-log_1_SYN0003042-000_f023c931-cb1a-4233-8a68-c10b2716699f.jpg?v=1786986701","url":"https:\/\/noiseroom.lt\/lt\/products\/doepfer-a-131-vca-exponential","provider":"Noise Room","version":"1.0","type":"link"}
