The A-117-2 is a workhorse noise module – simple, reliable, and sounds great. It’s a fantastic starting point for anyone exploring noise generation in Eurorack, or a useful utility for experienced users needing a compact, flexible noise source. Its clean digital character is surprisingly versatile.
Product Description
- Doepfer A-117-2
- Eurorack Module
- Digital noise generator
- Produces a random sequence of rectangular pulses
- Frequency of the internal oscillator adjustable from 50 - 40
- 000 Hz
- Frequency CV input with attenuator
- Input for external clock signal
- Bipolar and unipolar output
- Power requirement: 20 mA (+12V) / 10 mA (-12V)
- Width: 4 HP
- Depth: 45 mm
PROS
- • Excellent noise quality, surprisingly rich and textured for a digital module.
- • Wide frequency range (50-40kHz) allows for subtle to harsh noise.
- • Compact 4HP footprint makes it ideal for dense modular setups.
- • CV input provides dynamic control over the noise sequence's rate.
CONS
- • Limited output options; bipolar/unipolar can restrict certain patching scenarios.
- • Relatively basic functionality compared to more complex noise generators.
- • 45mm depth might create issues in shallow Eurorack cases.

Frequently Asked Questions
The digital pulse sequence offers a more structured, rhythmic noise than typical analog white noise; it's less 'hiss' and more 'granular'.
While possible, it's not its primary strength; you’d need significant processing to achieve convincing sibilance, but the rate modulation makes experimentation worthwhile.
It's a linear attenuator, offering predictable and straightforward control over the noise rate based on incoming CV voltage.
