It has been described as a filter, a waveshaper, a mangler, a crusher, and – my favorite – as an “FSU module”.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eI think calling it a filter may be a bit misleading, but I have no idea what else to call it. It is a filter, but it does more (all at the same time, really) excessive phase shifting, waveforming, ringing, formant generation, and so on. I guess it could be called a waveform modifier or enhancer, but those don’t sound good either. I nameed it the Plague Bearer for a reason.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eIf you are looking for technical synthophile specs you are out of luck here. All f(h) devices are designed in accordance with how they sound, not to achieve mathematical perfection. The most common question I receive is, “what is the filter slope?”\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eHonestly, I never measured that. I specifically avoided the conventional approach while I was designing this circuit, so it’s very problematic to try to describe this filter in the normal terms. The slope is directly tied to the gain of the circuit, making it variable, and the Q is affected by all three filter controls. The setup is actually a combined High- and Low-pass. The corner frequencies are adjusted by the controls and can be overlapped completely, which gives a comb-filtering effect.\u003cbr data-mce-fragment=\"1\"\u003eMost changes in the r4 were for ease of assembly purposes, but two new features were added:\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli class=\"first-child\" data-mce-fragment=\"1\"\u003eInput Attenuator: Earlier versions often required use of an external VCA to reduce input signal levels and prevent overdriving the input. This is now handled by the input attenuator.\u003c\/li\u003e\n\u003cli class=\"last-child\" data-mce-fragment=\"1\"\u003eOutput limiting: The output levels of earlier versions could spike well beyond ±5Vp-p, so an output limiter was added. The limiter has a soft to medium curve and can be disabled by moving the two jumpers as shown on the PCB.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003ctable class=\"specs\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage (min –\u0026gt; max)\u003c\/td\u003e\n\u003ctd colspan='2\"'\u003e±9V –\u0026gt; ±15V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"235\"\u003eSupply Current (max draw @ ±12V)\u003c\/td\u003e\n\u003ctd width=\"95\"\u003e+12V: 6.5mA\u003c\/td\u003e\n\u003ctd width=\"95\"\u003e–12V: 4.0mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage (@ ±12V)\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e0Vpp —\u0026gt; 10Vpp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e±5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput \u0026amp; Ouput (I\/O) coupling\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003eCapacitive (AC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Impedance\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e2.2µF in series with 1kΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl Voltage (CV) inputs\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e0V –\u0026gt; V+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOffset range\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e±5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCV input coupling\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003eDirect (DC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCV input impedance\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e100kΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"FLIGHT OF HARMONY","offers":[{"title":"Default Title","offer_id":42022542868653,"sku":"flight_of_harmony_plague_bearer_v4","price":119.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/3449\/7197\/products\/PBr4_front_500px.png?v=1670363927","url":"https:\/\/www.detroitmodular.live\/products\/flight-of-harmony-plague-bearer-1","provider":"Detroit Modular","version":"1.0","type":"link"}
