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.

Features

• -12dB/Octave multimode filter
• Low Pass, High Pass, Band Pass, and Notch Filter Types
• Fade knob between Low Pass and High Pas styles
• Resonance does not self oscillate but provides a very clean and creamy accentuation 
• Distortion occurs when the Level knob exceeds 50% for a dirtier and grittier tone.
