The FM input is typically connected to the output of the associated envelope generator (e.g. A-141-4). The envelope amount for all four filters is controlled by the FM knob and the CVFM input by means of four built-in VCAs, which are controlled by the FM control and CVFM input. This allows also voltage control of the envelope amounts.\u003c\/p\u003e\n\u003cp\u003eIn addition common frequency modulation for all filters is possible (e.g. by an LFO). For this the CVF input with attenuator can be used.\u003c\/p\u003e\n\u003cp\u003eThe range of the audio input level control (L) allows also clipping\/distortion with typical A-100 audio levels (e.g. from A-111-4) at the filter inputs. Even this parameter is voltage controllable as well as the resonance (Q).\u003c\/p\u003e\n\u003cp\u003eApplication: polyphonic patches (four VCFs with same parameters)\u003c\/p\u003e\n\u003cp\u003ePower consumption: 70mA at +12V and 70mA at -12V\u003c\/p\u003e\n\u003cp\u003eDepth: 50mm\u003c\/p\u003e\n\u003cp\u003e8 HP\u003c\/p\u003e\n\u003cp\u003eCondition: New\u003cbr\u003e\u003cbr\u003eInfo from Alex4\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Doepfer","offers":[{"title":"Default Title","offer_id":48340762591402,"sku":null,"price":305.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0517\/4699\/6394\/files\/image_ea179e37-eca4-49b5-89d7-1f1857354195.png?v=1779480760","url":"https:\/\/www.missionsynths.com\/products\/doepfer-a-105-4-quad-poly-vcf-special-order","provider":"Mission Synths","version":"1.0","type":"link"}
