Blunami Steam-2 Digital Sound Decoder with 8 Function Outputs (TUC884608)

The Blunami Steam-2 Digital Sound Decoder with 8 Function Outputs is a 1-amp digital sound module designed for easy plug-in operation with a 21-pin NEM locomotive connector. It brings authentic steam locomotive sounds and a cab-like feel to model trains, letting you enjoy realistic operation right out of the box.

Eight function outputs drive features such as braking, injectors, power reverse, and firebox flicker, while a broad library of sounds covers exhaust chuffs (10 variants), prime movers (up to 12), bells (12), whistles (over 90), air horns (40+), couplers, dynamos, and more. Dynamic Digital Exhaust (DDE) responds to throttle and grade by adjusting the exhaust to reflect the engine’s load, creating a convincing, locomotive-at-work soundscape.
