STUDIO ELECTRONICS 5089 MODEL D-TONED VOLT CTR FILTER
The 5089 filter is a voltage controlled, discrete analog, 24 db/oct
transistor ladder, low-pass filter, employing hand-matched transistors.
Our ladder low-pass filter—a subtractive analog sound synthesis
foundation—in its lowest FREQUENCY setting removes, or cuts off higher
frequency harmonics; its RESONANCE or Q circuit emphasizes those
harmonics to the point of “squealy,” giddy self-oscillation, tracking
the keyboard in its FULL setting quite nicely if seeking an alternative
sine wave.
Our 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 earthy warmth; smash it and a meaty, satisfying
overdrive—a maximum harvest of vintage 1960s and 1970s organic?sounding,
second?order harmonic distortion fill the plate. 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. All Boomstar
Modular filters are hand-built in the U. S. Pick-and-Place all the way!
Potentiometer Potential
Three attenuverter and four attenuation
pots control the FREQUENCY, RESONANCE, FREQ CV 1, RESO CV, FREQ CV 2,
INPUT and OUTPUT, delivering smooth, detailed, and complex expression.
Switch it Up
Classic Minimoog FULL and HALF strength filter frequency keyboard/voltage tracking for rounder low end with brilliant highs.
Patch it Up
Seven patch points: 1 V/O, FREQ CV 1, FREQ CV 2, RESO CV, INPUT and 2x OUTPUT direct the deepest manipulation.

* From 7:00 (0) to 9:00 our “Negative Resonance Saturation” adds
beefiness, boosting the waveform amplitude and taming waveform
transients; set to 9:00 to achieve the cleanest tone possible
