The Benidub DS71 Dub Siren is a compact tabletop synthesizer designed for quick and creative sound effects. It combines a fully analog oscillator, filter, and VCA with a digital LFO to create a wide range of siren tones.
Four trigger buttons recall different preset sounds, with a total of eight available across two banks. The DS71 can be activated directly or via external triggers such as piezo pads, sequencers, or audio signals. With intuitive controls, it’s an ideal tool for live performance and studio use.
