Blunami Diesel EMD Digital Sound Decoder 1-Amp 8-Function 21-Pin (TUC885609)

Blunami Diesel EMD Digital Sound Decoder is a plug-in sound module designed for diesels that use a 21-pin NEM connector. It provides 1 amp of power and eight function outputs, enabling authentic engine sounds and operating effects with straightforward plug-in installation.

Designed for easy fitment in compatible 21-pin locomotives, it offers a rich sound library and dynamic features to bring a diesel model to life. The Reactive Dynamic Digital Exhaust adjusts exhaust volume and tone as throttle and load change, delivering a lifelike ride whether the train is cruising on flat track or climbing a grade. The library includes exhaust chuffs (10), prime movers (up to 12), bells (12), whistles (90), and air horns (40+), plus controllable effects for brakes, injectors, power reverse, and firebox flicker. This combination helps recreate realistic diesel operation on any layout.
