Blunami Diesel GE 8-Function Digital Sound Decoder (TUC885610)

The Blunami 8-Function Diesel Digital Sound Decoder for 21-pin NEM locomotives is a compact, plug-in sound module that adds authentic diesel engine sounds and control features to compatible model trains. It delivers 1 amp of power and eight function outputs, enabling realistic sound and accessory control in one space-saving package.

Designed for easy installation with a 21-pin NEM connector, it offers Reactive Dynamic Digital Exhaust for sounds that respond to throttle and grade, plus functions like brakes, injectors, power reverse, and firebox flicker. The decoder also provides a broad library of sounds—exhaust chuffs, multiple prime movers, bells, whistles, air horns, and more—so modelers can tailor the audio to GE diesel locomotives and the era, without complicated setup.
