Used Moog Spectravox: semi-modular analog spectral processor and vocoder

This Moog Spectravox is a used unit that has been thoroughly tested and is in perfect working order. Joining the family of Moog semi-modular synthesizers alongside the Matriarch, Grandmother, Mother-32, DFAM, and Subharmonicon, the Spectravox combines a sophisticated 10-band analog filter bank with a powerful vocoder, offering virtually unlimited creative possibilities for sound design, music production, and sound experimentation.

10-band analog filter bank

At the heart of the Spectravox is a spectral processor based on ten voltage-controlled resonant filters: one low-pass filter, eight band-pass filters, and one high-pass filter. This architecture allows you to sculpt the harmonic content of any sound source, creating complex sweeps, evolving drones, and textures rich in movement.

Professional analog vocoder

By connecting a microphone to the XLR/Jack input with built-in preamp, the Spectravox transforms into a true 10-band analog vocoder. Vocal articulations can be processed and combined with the internal oscillator or external sources to produce classic robotic voices or completely original effects.

Semi-modular synthesis and Eurorack integration

Thanks to its 36 patch points (19 inputs and 17 outputs), Spectravox can be easily integrated into any Eurorack system or semi-modular setup. The extensive patchbay allows you to individually control the filters, modulate the vocoder’s behavior, and create extremely sophisticated processing paths.

Built-in Analog Oscillator and White Noise

The module features an analog VCO and a white noise generator that can be used as internal sources for the vocoder or as independent sound elements, further expanding the possibilities for experimentation.

A Creative Tool for Studio and Performance

From electronic music production to film sound design, from ambient textures to the classic vocal processing made famous by artists such as Kraftwerk, Stevie Wonder, and Daft Punk, Spectravox offers a modern approach to spectral synthesis while maintaining the warm, musical character typical of Moog instruments.
