Another filter that uses the circuitry of a classic.
This time it´s the Oberheim SEM (Synthesizer Expander Module), that was used e.g in the Four-Voice and Eight-Voice.
The filter has a saturated fat sound and especially in lowpass mode it growls in the bass range, very mighty and powerful.
The very sensitive audio input allows distortion of the audio signal which forms the sound even more.
The filter works with a slope of -12dB per octave and provides voltage controllable resonance without self-oscillation. It features a separate bandpass output and a combinated output that can be blended between lowpass, notch to highpass with a control. There are two CV inputs for controlling the cutoff frequency and the second input has a polarizer, a control with inverting/attenuating function. There´s a volume control at the audio input, potentiometers for setting the cutoff frequency and resonance.
Connectors: CV input 1, CV input 2, audio input, bandpass output, lowpass / notch / highpass output. All jacks are 3.5mm (1/8“) mono jack.
Dimensions: 3U Eurorack module / module width 8 HP / depth (from back of faceplate): 55mm / power consumption 30mA / weight: ca. 100g
