The TSU-PNP8 is a universal factory board replacement sound decoder suitable for use in many manufacturer’s diesel models such as those made by Atlas, Athearn, and InterMountain Models. It is suitable for a wide variety of models from HO to S scale.

This decoder includes a connector to easily add a CurrentKeeper (P.N. 810140 or 810160) to maintain performance over dirty track and switches.

DYNAMIC DIGITAL EXHAUST

For added realism, you’ll love the 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.
