Description

Dive into the sonic wilderness with the Doepfer A-124 Wasp Filter, a quintessential module for enthusiasts of unique, raw sound. This isn't just another filter; it's a voyage back to the era of the iconic EDP Wasp synth, known for its distinctive, unapologetically gritty tone. The A-124 brings that character into the modern Eurorack format, offering a blend of nostalgia and innovation that can add an edge to any sound design.

At the heart of its design, the A-124 features a 12dB multimode filter that captures the essence of the original Wasp's filter circuitry. This module stands out by using digital inverters in a novel way, emulating analog operational amplifiers to produce distortion and the characteristically "dirty" effects that define its sound. With its mix control, you can navigate through low-pass, band-pass, and high-pass filtering, or find the sweet spot for a unique notch filter effect, pushing the boundaries of your sonic palette.

Whether you're crafting throbbing bass lines, piercing leads, or atmospheric sweeps, the A-124 Wasp Filter offers dual CV inputs for expressive control, and two distinct audio outputs for versatile signal routing. Its capacity for sonic exploration makes it an enticing choice for modular enthusiasts seeking to inject their setups with a dose of vintage flair and modern versatility.

Key Features:

  • 12dB multimode filter inspired by the legendary EDP Wasp synth
  • Unique sound character thanks to the innovative use of digital inverters
  • Mix control for blending low-pass, band-pass, and high-pass filters
  • Dual CV inputs for enhanced modulation possibilities
  • Separate outputs for band-pass and a combined low/notch/high-pass signal
  • Compatible with Eurorack modular systems (8 HP width)
