Special features include automatic gain correction and a beefy distortion circuit. The module can self-oscillate. While doing so, it is possible to play it like an oscillator. Furthermore, there are individual outputs for audio material filtered with an edge steepness of -6 dB, -12 dB, -18 dB and -24 dB per octave. A fifth output can be switched between the slopes mentioned. One of two inputs is adjustable in level. Cutoff frequency and resonance parameters come equipped with CV inputs plus attenuators.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003eTransistor Ladder Filter w 1-4 poles LP and SELECT aux out Two audio in (one adj) and two CV In (one adj)\u003cbr\u003eCutoff, Res, w Automatic Gain Change and ext CV in Distortion, Amt Res CV In\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003ePanel Width: 10 HP +12V = 90mA -12V = 60mA\u003cbr\u003e+5V = 0mA\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003eCONTROLS\u003cbr\u003eFREQUENCY\u003c\/span\u003e\u003cspan\u003e: Cutoff Frequency of the Filter\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eRESONANCE\u003c\/span\u003e\u003cspan\u003e: Resonance\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eAGC\u003c\/span\u003e\u003cspan\u003e: Automatic Gain Compensation On\/Off.
