Doepfer A-102 Diode Low Pass Filter

Doepfer A-102 Diode Low Pass Filter Overview

The Doepfer A-102 Diode Low Pass Filter is a sonic recreation of a classic British-style low-pass filter in modular format for your Eurorack synthesizer. Designed with diodes over traditional transistors, the parameters for frequency cutoff and resonance are tied together, creating a unique resonant behaviour, unlike any other filter you've heard before. The diode construction means the A-102 is highly stable under high voltage signals, allowing you to create smooth and powerful high-cuts to add weight and excitement to your productions or live sets.

Jam-packed into an 8HP module, the Doepfer A-102 includes three CV inputs, with CV1 utilising 1V/Oct standard. Driving the resonance to the maximum into self-oscillation, this control allows you to patch pitch signals in and use the A-102 as its own dedicated sine wave generator.

Designed for analog enthusiasts, the Doepfer gives you the tools you need to take your sound design to the next level. Explore your creativity and cut instruments through dense mixes or create euphoric tension building before your track kicks in.

Full Description

Functional and powerful filter unit

Paying tribute to legendary British-style low-pass filters of the past, the A-102 is an authentic recreation of the classic Diode filter sound. Chosen for its specific interpolation between the frequency control and resonance dial, the A-102 can create unusual and interesting sounds because of this relationship. Tying the two functions together means that as you adjust one, the other is affected by the same change. Unique to only a few filters, the Doepfer A-102's aggressive 24dB/octave slope provides you with an exciting tonal palette to get creative with.

Packed into a small 8HP unit, the A-102 has been designed to offer maximum flexibility for portable Eurorack synths. The resonance dial has been perfected to offer self-oscillation when at maximum level. This combined with the CV1 input that uses 1v/Oct standardisation means that you can use the A-102 as a sine-wave oscillator by patching your pitch CV in. Ideal for VCO's, the Doepfer A-102 Diode can also offer standard filter tracking.

Featuring CV level controls for both CV2 and CV3, you can choose how much signal to let pass through, allowing you to work with most signal levels with enough headroom to avoid any unwanted distortion if you want a clean and powerful low-end.

Reshape your sound

An often overlooked aspect of Eurorack synth design is a low-pass filter. They provide you with a wealth of unique tonal shaping options from subtle and smooth to harsh and resonant. The A-102 Diode Low Pass Filter is no different. Offering a wide frequency sweep, you have complete control over your filtering, from adjusting the frequency to adding in a tremendous level of low-end resonance you can transform virtually any signal. Beef up kick drums, tame harsh sawtooth leads or use as a creative tool for euphoric build-ups, the A-102 Diode can do it all.

Featuring a sweepable resonance dial, you can now drive your signal even harder and into self-oscillation to add texture and grit to your tone. This is the perfect solution for transforming thin and anaemic lead lines to a weighty, full-bodied tone that can help add movement and energy to your music.
