The Filtare SEIII is a multimode, state-variable voltage-controlled filter that gives you low-pass, band-pass and high-pass outputs which are all simultaneously available. It also includes a notch output which allows you to change the balance between low-pass and high-pass. The SEIII uses discrete components but is based on SSM2040 architecture, giving you a very musical sounding filter. There are CV inputs for frequency, resonance and notch balance. The 1 V/O CV input for frequency can be used to have the filter follow what you're playing on the keyboard or just crank up the resonance and use it to play sine-waves. Specifications: Modes: LP, BP, HP All modes are 4-Pole (24dB/Octave) Notch: Change balance between LP and HP (total drop with balance at center is 3.4dB) Power supply: +/- 12 VDC (reverse-polarity protected!) Width: 8HP Inputs: CV (for frequency control): 1V/O fixed CV (for frequency control): Adjustable CV (for resonance) CV (for notch balance) Audio Outputs: Low-Pass Band-Pass High-Pass Notch Controls: Frequency Resonance CV Level (frequency) Notch Balance Volts / Octave Adjust for 1 V/O input (trim pot on back) Includes: Filtare SEIII Module Doepfer-style Power Cable (4) M3 x 6mm Rack Screws w/ Nylon Washers Sound Samples LP Frequency Sweep BP Frequency Sweep HP Frequency Sweep Notch Bal.
