Noise/Random Voltage Generator

Module A-118 is a noise and random voltage generator. It produces the following signals: white noise, coloured noise, and random voltage. White and coloured noise can be used as audio signals, and also (in conjunction with an S&H module) as a control voltage. The resulting random voltage is mainly used as a control voltage, especially because of its low frequency content.

There are knobs to control the rate of change and amplitude of the random voltage, and two LEDs indicate the state of the voltage.

  • Width: 8HP / 40.3 mm
  • Depth: 40 mm (measured from the back side of the front panel)
  • Power requirements: +20 mA (+ 12V) / -10 mA (-12V)

Excellent random signal and noise generator

I love this little unit -- so much so that I've bought two of them. As far as I can tell, it's the simplest and most cost-effective way of getting a random signal generator (instead of buying a noise generator and a Sample & Hold unit separately) and you also get two flavours of noise thrown in.

The unit generates White noise from its top socket, and Coloured noise from the one below it -- the colour being determined by a mix of the Blue and Red noise knobs. These also control the source for the random signal generator, which can be further adjusted for rate and depth (level) and which pipes its output to the bottom socket. A pair of little red LEDs wink in time with the random signal, giving you immediate feedback on whether you've got a slowly-varying random wave or some kind of insane high-speed chaos going on.

Link this thing to the CV input of pretty much any module and you can get some craziness going -- everything from subtle fluctuations to utter madness. I honestly think this is the most fun you can get for the least money in Eurorack format! Build quality is standard Doepfer -- ie, solid but aesthetically uninspired. Still, it's the guts of the thing that count, and they're top notch.

Very fine noise module, has most of the basic stuff a noise module would need to have. white noise, coloured noise and a random output with rate and level controls. Things can get very interesting when controlling other modules with for example the random output and then tweaking the rate and level knobs.
