Studio Electronics – Boomstar Modular 3003 Filter
The 3003 filter is a voltage controlled, discrete analog 18 db/oct ladder low-pass filter, employing hand-matched transistors. Drop the FREQUENCY knob to 0 and things get pretty dull; swing it back up and those “Transistor Bass” highs come crashing through the gate. The 3003’s RESONANCE circuit at max will sing out more than the TB’s signature chirping in a fun, bubbly, if washy, poorer relation, Mini “clone-ish” way; use it tastefully, or throw moderation to the wind for overwhelming chirp force.
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.
Classic Minimoog FULL and HALF strength filter frequency keyboard/voltage tracking for rounder low end with brilliant highs.
Seven patch points: 1 V/O, FREQ CV 1, FREQ CV 2, RESO CV, INPUT and 2x OUTPUT direct the deepest manipulation.
FREQUENCY – Adjusts the frequency, or cut-off of the filter.
