Cwejman NS-4 Noise-SampleHold-Lag


The NS-4 features two modules in one. On the one hand a noise generator with different colors and on the other hand a sample & hold generator with an internal lag (= slew limiter) and internal LFO.



The analog noise generator delivers white, pink an red noise at three separate outputs. The S&H generator is always triggered by the internal LFO which rate ranges from 0.1Hz to 500Hz and is controlled manually or with a 1V/octave control voltage. The LFO can be re-triggered by any (!) external signal.

The S&H uses the internal noise signal for sampling but also accepts an external signal which level can be adjusted by a potentiometer. Afterwards the S&H signal passes a slew limiter stage. It's slew time ranges from 0.1Hz to 1kHz and can be set with a control or a CV. Both CV inputs have attenuators so you can set the modulation intensity manually.

Trimmers on the backside allow you for adjusting the LFO rate.


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!
