Doepfer A-118 Noise/Random

60

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
guybblue 15.05.2013
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.

Can't live without this little box!

I just love the A-118... so much so that I now have three of them (and my Eurorack isn't that big, either). Of course there's noise: mixable Red and Blue, for a wide range of noise colours, plus pure White on a separate output. This is handy but also pretty standard.

For me, the killer feature here is the "random output" jack – which is a SMOOTHED, rather than stepped, random waveform generated from the noise source. I've started to realise that smoothed random waveforms are rare on synths: when there's a "random" LFO option, for example, it's almost always stepped – which isn't usually what I want. It's the same effect you get with a slew limiter or the "output lag" control on old Roland sample-and-hold circuits – so, a random but smoothly wobbly waveform whose depth and rate you can control. It's very neat indeed for adding low-level, almost subliminal pitch variation to oscillators for a really gnarly vintage vibe, and I like to feed random CVs out to my more well-behaved monosynths to liven them up a bit :-D

A solid little module with a really neat trick up its sleeve: highly recommended.

Fantastic module! Excellent value for money, the noise output can give a mixable Blue/Red output or just straight white noise.

The random voltage output is really fun to have in a patch to add a bit of spontaneity.

Build quality is excellent, and the features make this module very good value for money.

Good One!

Nice module. You can shape the noise to get the sound you prefer. Even the random function works well.
