Doepfer A-106-5 12dB SEM Filter Special Edition

Temporarily a special edition of the Doepfer A-106-5 12dB SEM Filter is available. It is equipped with a stylish Oberheim-style cream-coloured anodized front panel and black knobs.

A-106-5 SEM
Filter
Special Edition
Module A-106-5 is a 12dB multimode filter that is based on the filter circuit of the Oberheim SEM
module.
The filter is equipped with a band pass output and a combined low/notch/high pass output. 
For this output a control knob defines the relation between low and high pass signal. 
If both signals appear at the same level (i.e. middle position of the Mix knob) one obtains a notch filter. Otherwise the low or high pass signal predominates. 
The module does not feature self oscillation in contrast to most of the other filters of the A-100 system. 
The module generates a distorted audio signal if the level control is set to about 50% (i.e. center position) or more with A-100 standard signals like VCOs.

Inputs: Audio In, CV1 In without attenuator, CV2 In with Polarizer
Outputs: Bandpass Out, Low/Highpass Mix-Out
Controls: Audio Attenuator, CV2 Polarizer, Frequency, Resonance, LP/HP Mix
