Doepfer A-106-5 12dB Filter (SEM)
- Order number: 120078
- Depth: 55
Another filter that uses the circuitry of a classic. This time it´s the Oberheim SEM (Synthesizer Expander Module), that was used in the Four-Voice and Eight-Voice for instance. 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 potentiometer.
There are two CV inputs for setting 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.

A-106-5 @Doepfer
WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
