Back in 1979, this vocoder brought Harald Bode's groundbreaking design to Moog's lineup, turning human voices into robotic symphonies on tracks like Giorgio Moroder's E=MC2—pure analog magic from the golden era of synth processing.
It's a 16-band analog signal processor that splits your modulator (like a voice or drum) into precise frequency bands from 50 to 5080 Hz, then imposes those timbres onto an external carrier synth for incredibly articulate results. No built-in oscillators means it's all about pairing with your rig: mic and line inputs for the modulator, 16 dedicated synth inputs and outputs for each band, plus a cross-matrix patching system with included cords for wild custom routing. Housed in a rugged 6U rackmount chassis with reversible handles, it packs illuminated switches, precision pots, a 6ms response for snappy percussion, sample-and-hold for frozen phrases (footswitchable), high-frequency bypass, and controls for hiss, buzz, and balance. One envelope shapes the action, with stereo out and balanced connections ready for pro setups.
Vintage players and collectors chase these rarities, praising the natural speech clarity and timbral depth that still crush modern digital imitators, though pristine serviced units command top dollar due to their scarcity.
