"Moog Vocoder (Bode) 16-chan 327A 100% Restored / PERFECT CONDITION

These amazing pieces of history are listed once every couple of years, they are simply IMPOSSIBLE to find.

Just completely rebuilt and serviced by Phil at CMS/Discrete Synthesizers in December of 2018. Due to a rent increase at my studio, Tiny Telephone in San Francisco, I am forced to sell some prized gear.

Rare Moog Vocoder Model 327A/MBVO (16-channel), co-designed by Dr. Harald Bode & Dr. Bob Moog. The Moog Vocoder was used by artists including Wendy Carlos, Moog Cookbook, Devo, Saga, Yellow Magic Orchestra, and filmmaker/composer John Carpenter, among others.

In 1979, Moog Music released its vocoder, although its design and architecture are almost identical to the Bode 7702 model. It's a 16-band analog vocoder, which separates voice/synthesizer sounds (carrier signal) into frequency-bands ranging from 50 to 5080 cycles-per-second. It does not have any internal oscillators, so it is designed to be used as a signal processor for external carrier & modulator wave sources. The modulator is typically a vocal or drum beat used to modulate the carrier/synth sound being processed. It has microphone & line inputs, as well as 16 synthesizer inputs (1 for each frequency-band), and 16 outputs. This 16-channel cross-matrix patching system provides incredible flexibility, allowing for full external patching between synth & vocoder sections. Other features include a high-frequency bypass, a short 6ms response time for capturing fast percussive sounds, sample-and-hold, and a global bypass switch to turn off the vocoding effect (it has no built-in output mixer, MIDI or CV/Gate).

Sounds amazing! Recent service included replacement of parts, recapping, cleaning, self-noise improvement and alignment. Includes power cord, and 10 patch cords. The handles/rack-mounts are reversible. 115v/220v switchable. In great physical condition but has some surface scratches, etc. Message Seller with any questions. Moog Vocoders have sold for more than US$10,000 on eBay and Reverb."
