The A-123-2 is an analog high-pass filter with four outputs for slopes ranging from -6 dB to -24 dB per octave. It is based on the special IC CEM3320/AS3320 and delivers both clean and distorted sounds. Cutoff frequency and resonance are voltage controllable.
The A-123-2 from Doepfer is a versatile and good sounding high-pass filter. The module is based on the special IC CEM3320/AS3320.
It features four different slope outputs:
The sound of this filter is very clean. However, if the input is overdriven, a hard high-pass filtering may occur. So it offers different flavors depending on the application.
The cut-off frequency can be controlled manually and by means of control voltage. There are two CV inputs, one of which is equipped with an attenuator.
The resonance (Q) is also manual and CV-controllable, which allows for interesting sound experiments.

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.
