LED Friendly Functions
The 8 function outputs are LED-friendly so resistors are not required for LEDs! (See the wiring diagrams under product documentation for more information). Light effects are fully remappable and offer full access to our 20+ HyperLight effects.
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.
