Frequency, resonance and level are controlled for each filter separately (no voltage control). The frequency range for the filters is about 50Hz...5kHz. The filter audio inputs are very sensitive so that distortion may intentionally be used to create new sounds - if desired. The A-104 is a versatile module for sound modification.\u003c\/p\u003e\n\u003cp\u003eIn the first place it is used for reproduction of resonances (e.g. the vocal-like effects known from the Trautonium). In combination with the subharmonic generator A-113, the Trautonium Manual A-198 and some other A-100 modules one obtains a Trautonium replica.\u003c\/p\u003e\n\u003cp\u003ePower consumption: 30mA at +12V and 10mA at -12V\u003c\/p\u003e\n\u003cp\u003eDepth: 45mm\u003c\/p\u003e\n\u003cp\u003e20 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":48340759609514,"sku":null,"price":190.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0517\/4699\/6394\/files\/image_f3c8b64c-9fc0-4cfe-ab4d-a82d7dcfb399.png?v=1779480325","url":"https:\/\/www.missionsynths.com\/products\/doepfer-a-104-quad-resonance-filter-special-order","provider":"Mission Synths","version":"1.0","type":"link"}
