Doepfer A-118 Noise and Random Voltage Generator
A-118 Noise/Random · Doepfer
12 for sale on Reverb2 finishes at Thomann
The A-118 is a workhorse noise module, pure and simple. It’s fantastic for creating evolving textures, subtle rhythmic modulation, and adding a bit of unpredictable character to your patches. Perfect for experimental sound designers and those wanting a reliable, budget-friendly noise source in their Eurorack.
Pros
- Classic Doepfer build quality: robust, reliable, and feels very solid.
- Versatile noise generation: white, coloured, and genuinely useful random voltage.
- Low-frequency random voltage ideal for subtle modulation and rhythmic patterns.
Cons
- Limited control compared to more advanced noise modules.
- Power draw could be a factor in systems with limited power supplies.
-
The A-118-2 is a surprisingly capable noise generator for the price. It’s a great starting point for anyone dipping their toes into modular synthesis or needing a compact, reliable source of random elements – perfect for generative patches, percussive textures, or subtle modulation. The random voltage output is particularly useful for adding unpredictable movement.
Pros
- Excellent noise quality, surprisingly clean and usable.
- Versatile random voltage output with useful level control.
- Track/Hold and Sample/Hold modes offer creative modulation.
Cons
- Limited noise color shaping compared to more expensive modules.
- The level control can be a bit fiddly with fast changes.

How to choose the best noise modules
Heritage & Design Philosophy
Doepfer's a foundational name in Eurorack. Their modules are built around a utilitarian, no-nonsense design - they're not trying to be something they're not. This results in a predictable, reliable character that's a welcome contrast to some of the more 'creative' (read: sometimes flaky) designs out there.
Tone Character - That Gritty Edge
Forget pristine, clinical noise. Doepfer noise modules often have a characteristic grit and a subtle harmonic complexity. It's not always pleasant, but it's interesting, especially when you're layering it under drones or using it for percussive textures. It's got a certain 'analog fatigue' that adds realism.
Build Quality & Reliability
These are tank-like. Seriously. The metal casework is thick, the jacks are robust, and the pots feel solid. You're not going to be worrying about these failing mid-gig, which is a huge deal when you're relying on them to build a soundscape.
Simplicity of Controls
Doepfer modules generally keep things straightforward. No endless menus or obscure parameters - what you see is what you get. This makes them incredibly easy to integrate into any system, regardless of your experience level. It's about getting sounds, not fighting interfaces.
Voltage Stability & Tracking
Doepfer modules are known for their excellent voltage stability. This means the noise output will remain consistent as you modulate it with other modules, which is critical for predictable and usable results. Poor voltage tracking can make noise modules sound erratic and unusable - Doepfer avoids that.
Buying guide
Alright, so you're diving into the wonderful world of Eurorack noise? Good choice - it's the sonic spice rack of synthesis. Doepfer noise modules have a long and respected history, and for good reason. They're not flashy, but they're rock-solid, reliable, and offer a unique character you won't find everywhere else - especially if you're after that gritty, vintage vibe.
If you're new to modular, a Doepfer noise module is a safe bet - you're getting a classic design built to last. Don't expect groundbreaking innovation, but do expect a reliable, characterful sound. Used Doepfers are often a great value, but inspect the pots for wear - they can sometimes get scratchy over time.
If you're chasing pristine, sterile noise, these aren't for you; they're best suited for adding texture and grit.
How the AudioFu Index works
Five measured signals and nothing else — no stars from strangers, no “tested by experts” we didn’t do. The weights are fixed and public. We don’t play these instruments; we measure the market around them.

Questions
Are Doepfer modules still being made?
Production slowed significantly after Dave Simmons' passing, but Doepfer continues to offer a selection of modules, including some noise modules. Availability can be spotty and prices can be higher due to their vintage status.
How do Doepfer noise modules compare to Mutable Instruments' offerings?
Mutable Instruments tends to be cleaner and more precise, often with a wider range of tonal possibilities. Doepfer's are grittier, more vintage-sounding, and generally more straightforward in their operation.
Can I use a Doepfer noise module in a live performance?
Absolutely. Their rugged build and predictable behavior make them ideal for gigging. Just be mindful of the slightly darker, less bright tone - it might need a little EQ boost to cut through the mix.
What's the difference between the A-110-5 and the A-110-7 noise modules?
The A-110-5 is a basic, classic noise source. The A-110-7 adds a sample-and-hold function, allowing you to create stepped noise patterns - a useful addition for rhythmic textures and sequencing.
Are Doepfer modules difficult to repair?
They're relatively simple internally, which means repairs are often straightforward. Parts are generally available, although some components might be harder to source than for more modern modules.
