In the “off” position, the Highpass and Lowpass Filters are disconnected from the 904C and may be used independently. When switched to the “Brandpass” mode, Highpass and Lowpass Filters are coupled in parallel to process a central band of frequencies – deleting both bottom and top. The bandreject mode presents the inverse relationship, rejecting a central frequency band, and passing only the lowest and highest frequency components. Voltage controlled bandwidth and center frequency controls are included on the coupler. Bandwidth can be etended to three octaves with manual settings or control voltage. Center Frequency ranges from 5Hz to 20kHz, via manual or voltage controlled settings.\u003c\/p\u003e \u003cp\u003eWhen using the 904C for Bandpass or Bandreject filtering, the following standard settings should be obeserved:\u003cbr\u003e \u003c\/p\u003e \u003ctable align=\"left\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003e904A Fixed Control Voltage\u003c\/td\u003e \u003ctd\u003e \u003c\/td\u003e \u003ctd\u003e=\u003c\/td\u003e \u003ctd\u003e \u003c\/td\u003e \u003ctd\u003e+6\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e904A Frequency range\u003c\/td\u003e \u003ctd\u003e \u003c\/td\u003e \u003ctd\u003e=\u003c\/td\u003e \u003ctd\u003e \u003c\/td\u003e \u003ctd\u003e2\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e904B Fixed Control Voltage\u003c\/td\u003e \u003ctd\u003e \u003c\/td\u003e \u003ctd\u003e=\u003c\/td\u003e \u003ctd\u003e \u003c\/td\u003e \u003ctd\u003e-1\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e904B Frequency Range\u003c\/td\u003e \u003ctd\u003e \u003c\/td\u003e \u003ctd\u003e=\u003c\/td\u003e \u003ctd\u003e \u003c\/td\u003e \u003ctd\u003elow\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003cp\u003e\u003cbr\u003e \u003c\/p\u003e \u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003cbr\u003ePassband settings = Bandwidth knob plus control voltage.\u003cbr\u003eNotchwidth = Minus bandwidth knob minus control voltage.\u003c\/p\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"Synth-Werk","offers":[{"title":"Default Title","offer_id":54725876187477,"sku":null,"price":228.75,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1071\/1872\/3413\/files\/904CVCFCOUPLER.jpg?v=1787441760","url":"https:\/\/climivor.myshopify.com\/products\/synth-werk-sw904c-filter-coupler","provider":"CLIMIVOR","version":"1.0","type":"link"}
