Studio Electronics 3003 Filter

The 3003 filter is a voltage controlled, discrete analog 18 db/oct ladder low-pass filter, employing hand-matched transistors.

The 3003 filter has the most gentle sonic touch of its partners in the Boomstar fold, but nevertheless is quite capable of shaping precise, very dynamic tone.

• 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.

All Controls and Patch Points:
 

• FREQUENCY – Adjusts the frequency, or cut-off of the filter.
• RESONANCE – Adjusts the resonance of the filter.
• FULL HALF TRACK – Switch between full and half keyboard/voltage tracking
• FREQ CV 1 – Frequency control voltage 1 input attenuverter
• RESO CV – Resonance control voltage input attenuverter
• FREQ CV 2 – Frequency control voltage 2 input attenuverter
• INPUT – Adjusts the audio input
• OUTPUT – Adjusts the audio output
• 1 V/O – One volt per octave control voltage input
• FREQ CV 1 – Frequency control voltage 1 input
• FREQ CV 2 – Frequency control voltage 2 input
• RESO CV – Resonance control voltage input
• INPUT – Audio input
• OUTPUT x2 – Audio outputs.
