Cwejman ATT-4 Attenuator


The ATT-4 is a fourfold attenuator with switchable offset. Its primary task is the attenuation of modulations in case CV inputs don't have their own attenuators. If set to to bipolar mode audio signals can also be attenuated.



The module consists of four identical units which feature one inupt, one output and a level potentiometer. The offset- or BIAS-switch converts bi-polar signals like audio signals or LFO signals which reach from -2.5V to +2.5V (5V amplitude) in unipolar signals from 0-5V.


Generally all Cwejman modules are screened against interferences, protected against reverse polarity and contain calibration options on the backside, see big photo.

attention: Unlike other manufacturers, the red stripe of Cwejman's flat ribbon cable indicates the positive +12V rail, not the negative one!
