The Tsunami2 TSU-BigSteam
The TSU-Big Steam is available in multiple board formats and 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 in aftermarket Tsunami2 as well. 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.
