Studio Electronics Boomstar Modular 5089 Filter

The 5089 filter is a voltage controlled, discrete analog, 24 db/oct transistor ladder and low-pass filter that features hand-matched transistors. In its lowest FREQUENCY setting, the ladder low-pass filter removes, or cuts off higher frequency harmonics; its RESONANCE or Q circuit emphasizes those harmonics to the point of giddy self-oscillation, tracking the keyboard in its full setting if seeking an alternative sine wave. The 5089 has the roundest, slickest tone of all the Boomstar's filters. Go easy on it, and round, creamy buttery flavors wrap the oscillators in an earthy warmth; smash it and a meaty, satisfying overdrive of vintage 1960s and 1970s second‑order harmonic distortion emerges. Every setting is balanced and bountiful. Looking for traditional R ’n B baselines and leads? Focus here on the rich saturation of this benchmark filter and its symmetrical cascades of generation-stretching timbres. Potentiometer Potential Three attenuverter and four attenuation pots control the FREQUENCY, RESONANCE, FREQ CV 1, RESO CV, FREQ CV 2, INPUT and OUTPUT. Switch it Up Classic Minimoog FULL and HALF strength filter frequency keyboard/voltage tracking for rounder low end with brilliant highs. Patch it Up 1 V/O, FREQ CV 1, FREQ CV 2, RESO CV, INPUT and 2x OUTPUT.
