Socket CVT can be normalled to an internal fixed voltage (i.e. the switching contact is then connected to an internal fixed voltage). That way it's possible to change e.g. all time parameters simultaneously by means of the CVT control.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eAnother jumper is used to set output 2 to normal or inverted envelope.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eIn the factory CVT is assigned to all time parameters (A,D,R) zugeordnet, socket CVT is normalled to a fixed voltage and output 2 is not inverted.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eChanging the positions of the mentioned jumpers allows to modify the factory settings. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eAdditional technical information:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe voltage level of the used gate signal has to be at least +5V and the rising\/falling slopes has to be fast enough. Otherwise the envelope will not work in the right way. We discovered that some modules from other manufacturers do not meet these specifications. In this case the level shifter module A-183-4 may help by connecting one unit of the the module between the gate source and the gate input of the A-140-2.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cb\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eWidth: 4 HP \/ 20.0 mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eDepth: 40 mm measured from the rear side of the front panel\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eCurrent: +30 mA (+12V) \/ -20 mA (-12V)\u003c\/span\u003e\u003c\/p\u003e","brand":"Doepfer","offers":[{"title":"Black [Vintage]","offer_id":67586101477546,"sku":null,"price":127.0,"currency_code":"USD","in_stock":true},{"title":"Silver [Original]","offer_id":67586101510314,"sku":null,"price":115.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0020\/5199\/7743\/files\/140-3.jpg?v=1778883873","url":"https:\/\/www.noisebug.live\/products\/doepfer-a-140-3-micro-adsr","provider":"Noisebug","version":"1.0","type":"link"}
