a-106-5 12db sem filter special edition price : $125.00

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

the function and operation of this module is very similar to the wasp filter module a-124. but the sound of both filters is very different! we will publish no separate user's manual for the a-106-5 but a combined manual for both a-106-5 and a-124. the only functional difference is the position of the sockets and controls, and the function of the controls cv2 (a-124: normal attenuator, a-106-5: polarizer)



this module has a maximum current draw of 30ma. it requires 8 hp/te worth of space to fit in a eurorack frame.
