cwejman ns-4 price : $485.00

the ns-4 is a true analogue noise generator with four noise/random signal outputs; sample and hold (s/h), white, pink and red.

s&h:
the s&h generates a random signal controlled by two voltage controlled parameters; rate and lag (slew rate). the rate controls the period for every sample point from 10 seconds (0.1 hz) to 2 millisecond (500hz). the lag controls the slew rate of the incoming s/h signal from 0.1 hz to 1000 hz. the outgoing signal is, in other words, filtered by a voltage controlled low pass filter with 12 db/octave slope. the s&h rate and the s&h lag can be controlled manually by knobs and by external signals (rate cv and lag cv). rate generator can be sync-ed by an external signal and with any shape (s&h trig input). the s&h can be also used for an external signal (ext s&h) and the level of incomming signal is controlled manually (ext s&h level).

white noise:
white noise is a full audio bandwidth noise generator.

pink noise:
pink noise is a filtered white noise generator by 3db/octave across the whole audio frequency range.

red noise:
red noise is hard filtered and contains essentially only frequencies up to 200 hz.

performances:
s/h rate: 0.1 second to 2milliseconds
rate cv: from 0 to 1volt/octave
s/h lag: from 0.1 hz to 1 khz
s/h lag cv: 0 to 1 volt/octave

current consumption: 20ma
dimensions128.4mm (h), 30.5mm (b) 3 he, 6te
