Description

Edit description

Dive into the world of sound exploration with the Doepfer A-118-2 Noise module, a compact yet powerful addition to your Eurorack setup. This 4HP noise and random-voltage generator is designed to enrich your sonic palette with its versatile noise shaping capabilities. The module allows you to finely tune between two colored noise outputs: blue, which enhances high-frequency content, and red, which boosts the low-end frequencies. Additionally, a dedicated white noise output provides even more textural possibilities.

What sets the A-118-2 apart is its integrated sample-and-hold (S&H) and track-and-hold (T&H) circuitry. These features, typically found in more complex modules, allow you to manipulate random voltage signals with precision. Adjust the rate of change and amplitude using intuitive knobs, or switch between S&H and T&H modes for dynamic, clock-synchronized modulation. Whether you're crafting ambient drones or adding unpredictable elements to your music, this module has you covered.

Ideal for both seasoned synth enthusiasts and newcomers, the Doepfer A-118-2 provides a straightforward interface with maximum flexibility, making it a staple in any modular rig.

Key Features:

4HP noise/random-voltage generator Eurorack module
Adjustable blue and red noise levels for tailored sound
Independent outputs for colored and white noise
Rate and level controls for fine-tuning random voltage signals
Selectable sample-and-hold and track-and-hold modes
External clock input for T&H mode compatibility

PROS

Most natural sounding white noise in Eurorack
Combines noise and sample/hold functions, saving space
Excellent for drums and weather modulation sounds
Good sound quality for all noise applications

CONS

Difficult to dial in settings without an oscilloscope
Small interface, hard to read labels
Initial drift upon power-up, stabilizes after a few minutes
Cable spacing is very tight, making full use difficult

Features and functionality

0 0

Using T&H with audio-rate clocking creates a unique down sampling effect, converting continuous waveforms into stepped voltage approximations.
Source
0 0

Stepped random voltage output can creatively control voltage-controlled switches, introducing randomness into melodic sequences.
Source
0 0

The red knob significantly influences the random and S&H outputs, causing voltage clipping even with slight adjustments, particularly when interacting with the level knob.
Source
0 0

Adjusting the red and blue knobs alters clipping points when the level is adjusted, a behavior confirmed as normal by Doepfer.
