DYNAMIC DIGITAL EXHAUSTĀ For added realism, youā€™ll love SoundTraxx's reactive Dynamic Digital Exhaust (DDE) feature that automatically notches your model's engine up or down depending on the load on the motor. With the Blunami App, DDE calibration has never been easier.Ā 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 Blunami the ability to createĀ the most realistic experience possible.
