5089 Filter Module
Description
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, and a maximum harvest of vintage 1960s and
1970s organic

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!
