Doepfer A-106-6 XP Filter
NoiseBug Price : $227.00
module a-106-6 is a multimode filter that is based on the filter circuit of the oberheim xpander. the module features 15 different filter types (those filters of the a-107 that were available in the xpander) with 8 filters available simultaneously. the toggle switch filter group is used to switch between 2 filter groups.
threse filter types are available:
1l (6 db low pass)
2l (12 db low pass)
3l (18 db low pass)
4l (24 db low pass)
1h (6 db high pass)
2h (12 db high pass)
3h (18 db high pass)
2b (6 db band pass)
4b (12 db bandpass)
2h1l (asymmetrical band pass made of a 12 db high pass and a 6 db low pass)
3h1l (asymmetrical band pass made of a 18 db high pass and a 6 db low pass)
2n1l (combination of notch and 6 db low pass)
3a1l (combination of allpass and 6 db low pass)
the module features voltage controlled resonance. for filter group 2 (2l, 4l, 2b ...) even self oscillation is possible.
all standard vcf controls are available: manual filter frequency control frq, one control voltage input with attenuator (fcv2)and one without attenuator (fcv1, ~ 1 v/octave). in addition voltage controlled resonance with manual control (q) and a cv input with attenuator (qcv) are available.
this module has a maximum current draw of 50ma. it requires 12 hp/te worth of space to fit in a eurorack frame.
