Filters based on IR3109 had several drawbacks, including a volume drop when the resonance is increased so we added a volume drop compensation as well as a built-in VCA for more versatility in compact setups. Additionally, 1V\/oct tuning is implemented so you can use this module for perfect VCF keyboard tracking and also as a VCO.\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudio level\u003c\/td\u003e\n\u003ctd\u003e10Vptp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCutoff CV level (full span)\u003c\/td\u003e\n\u003ctd\u003e-5V - +5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVCA CV level\u003c\/td\u003e\n\u003ctd\u003e0 - +10V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax power consumption\u003c\/td\u003e\n\u003ctd\u003e25mA@+12V, 25mA@-12V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule width\u003c\/td\u003e\n\u003ctd\u003e10HP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule depth\u003c\/td\u003e\n\u003ctd\u003e35mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Photosynthesis","offers":[{"title":"Default Title","offer_id":47845116707003,"sku":null,"price":115.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2986\/3355\/files\/Erica3109VCFVCAhi.jpg?v=1778973946","url":"https:\/\/www.photosynthesisolympia.com\/products\/erica-3109-vcf-vca-eurorack-module-used","provider":"Photosynthesis","version":"1.0","type":"link"}
