DOEPFER A-121-3

• voltage-controlled multi-mode filter with a cut-off slope of -12 dB / octave
• four simultaneous outputs are available, each with different characteristics: low-pass (LP), high-pass (HP), band-pass (BP) and notch (N)
• manual control Frequ. for the cut-off frequency of the filter (the cut-off frequency determines the point at which the respective filter effect appears)
• two inputs for frequency control by means of external control voltages (frequency modulation, e.g. by ADSR or LFO):
• control voltage input CV1 without attenuator, about 1V/octave sensitivity
• control voltage input CV2 with attenuator FCV2 for the adjustment of the modulation depth of input CV2
• frequency range about 10Hz ... 20kHz
• manual control Q for the resonance of the filter
• control voltage input CQ without attenuator for voltage control of the resonance
• resonance up to self-oscillation, in which case the module will behave like a sine wave oscillator even without audio input signal
• audio input In with attenuator Level for the adjustment of the filter input level (beyond about pos. 5 clipping/distortion occurs with typical A-100 audio levels)
