    Blunami will change the way you enjoy the model railroading hobby! The Blunami BLU-4408The BLU-4408 is designed to wirelessly operate models with higher stall currents such as some S, O, and large scale locomotives; this decoder features easy-to-use terminal blocks for no-fault wiring and a higher audio amplifier for awesome volume, indoors or out. Blunami decoders can be operated in three different ways: DC, DCC and Wireless mode. Using the Blunami app (iOS versions 8 or later), you can operate your locomotive with incredible ease of use. You will feel like you are in the cab with the amazing new features that Tsunami2 has to offer including: Reactive Dynamic Digital Exhaust, Functioning locomotive and train brakes, injectors, power reverse, and firebox flicker. We also offer a large selection of selectable sound effects including: exhaust chuffs(10), prime movers (up to 12), bells (12), Whistles (90), airhorns (40+), couplers, dynamos and more! DYNAMIC DIGITAL EXHAUST For added realism, you’ll love our reactive Dynamic Digital Exhaust (DDE) feature. When your locomotive is traveling across flat terrain and simply maintaining speed, you will hear your locomotive chugging along. But, when the locomotive encounters a grade and the engineer applies more throttle to get the train up the hill, the engine sounds will automatically react and reflect the increase of power needed to crest the hill. DDE accomplishes this by calculating the changes in strain or load on the motor and adjusting the exhaust to appropriately simulate the work the engineer would be doing to the throttle of the engine. This gives Tsunami2 the ability to create the most realistic experience possible.HIGH QUALITY SOUND LIBRARYOur large selection of high quality sound effects include:  10 Exhaust Chuffs Up to 12 Prime Movers in each sound profile  Up to 12 Bells  90 Whistles 40+ Airhorns Additional couplers, dynamos, cab chatter and more! ADDED REALISMAdditional realism can be simulated by adding functioning locomotive and train brakes, injectors, power reverse, firebox flicker and more. EASY INSTALLATIONNo soldering required!
