U-012 Dual Attenuverter + DC (4HP)


U-012 Dual Attenuverter module for Eurorack/Doepfer A100 system.

From top:
input jack
attenuation/inversion knob
DC shift knob
output jack + 2 polarity LEDs
and same for second channel

U-012 allows manipulation with input signal, red knobs sets signal attenuation and/or inversion, white knobs sets DC offset (transposition). Red knob “under” 12 o´clock (ccw) inverts signal, over 12 o´clock (cw) lefts signal in same polarity, max. attenuation is in the mid (12 o´clock = “0”). Attenuation at knob max. position can be trimmed to exactly “1” (=no attenuation) using internal trimmers (to pass CV signal unchanged if an tuning CV is used as input to preserve tracking. DC knob then makes transposition). Second channel is normalled to first channel so you can create counterbalanced CV waveshapes with different DC shift (say for auto-panning signal with an envelope or LFO as modulation source and two VCAs for panning audio, inversion of one channel makes amplification conversely between channels. Or crossfades between two inputs). U-012 can convert CV signals between different level schemes, say input signal range +-5V can be converted to 0-5V, gates can be inverted and their level changed and much more… (as fixed CV source without input connected, deeper closing VCAs or VCFs if CV is moved slightly negative…)

Width: 4TE/ 4HP/ 20mm
Depth: 46mm /1,8″ max.
Current: 15mA max.
Power cable included

Double check power connection before powering your system please.
„Red strip“ means -12V connector side in Eurorack standards.
In some power distribution systems connector key can be reverted.
In this case cut connector key and plug power connector right way (with respect to red strip) or use different power cable appropriate to your power system
