The Tsunami2 TSU-BigSteamThe TSU-Big Steam is a limited edition decoder available in 3 board formats. This decoder features a true UP Big Boy recording! Previously this sound file was only offered in Athearn factory installed decoders, but now you can get it on our web store. This decoder is available in 3 board formats: TSU-1100, TSU-2200, and TSU-21PNEM8. You will also get all of the features that you know and love from our Tsunami2 decoder line 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: bells (12), Whistles (90+), 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 INSTALLATIONThe TSU-2200 can simply plug into models equipped with a DCC quick plug. Our 9-Pin JST to NMRA 8-Pin Wiring Harness (P.N. 810135) can also be use to plug the TSU-2200 into models equipped with an NMRA 8-Pin plug. The TSU-2200 can also be wired into a large variety of models. The TSU-21PNEM8 simply plugs into models equipped with a 21-pin NEM socket. These decoders include an optional capacitor or can be wired to a CurrentKeeper (P.N. 810140 or 810160) to maintain performance over dirty track and switches.
