The Doepfer A-124 Wasp Filter is an 8HP multi-mode filter module that utilizes the circuitry of the classic EDP Wasp synthesizer. The A-124 Wasp Filter incorporates digital inverters as analog op-amps to achieve the Wasp’s signature dirty and distorted tonality. It features a bandpass output and a combined low/notch/high-pass output that can be controlled using a Mix knob. The A-124 Wasp Filter has various controls including Lev. (Audio Level), Frq. (Cutoff Frequency Control), CV 2 (Attenuator for CV 2 Input), Res. (Resonance Control), and Mix (Control for Low/High-Pass Signal Amounts). The module has inputs for Audio In, Cutoff Freq. CV Input (CV 1 and CV 2), and outputs for Band-Pass Out and Mixed LP/HP Filter Out. The A-124 Wasp Filter is perfect for modular systems and provides a unique and distinctive filter sound.
