Doepfer A-102 Diode Low pass Filter
- Order number: 120073
- Depth: 60
The A-102 Module from Doepfer offers a unique filtering experience with its classic diode filter design.
Doepfer’s A-102 Module revives the sound of a classic low pass filter with a unique twist. The A-102 is not just any filter; it's a careful reproduction of the historic diode-based design, known for its very distinct resonance behaviour and frequency response.
The interface of the A-102 draws inspiration from Doepfer's A-120 Moog low pass filter and the A-103 (18dB TB303 Filter), sharing the same operational controls, inputs, and outputs. However, what sets the A-102 apart is its sound. The filter's core, powered by diodes in the filter stage, offers a unique resonance that deviates from the norm, providing you with sounds ranging from the subtle to the verge of extreme.
Another tip - when the resonance of the filter is turned up near its highest level, it enters self-oscillation and mimics a sine wave. This allows you to use the filter as an extra oscillator.
Key Features:
- Diode-based low pass filter design with a unique resonance behavior and frequency response.
- Three CV inputs with attenuators for CV2 and CV3.
- Input level control.
- Resonance capable of self-oscillation.

A-102 @Doepfer
WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
