The Tsunami2 TSU-BH1
Get an easy upgrade for your Bachmann Sound Value diesel models with our newest Tsunami2 decoder! The TSU-BH1 offers 8 LED-friendly function outputs 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.

This decoder is available in 3 sound profiles EMD, GE, and ALCO. For an easy install, simply replace the Sound Value decoder and enjoy all of the Tsunami2 features you love!

This decoder is designed to replace the factory board in the following Bachmann Sound Value Diesel Models: FA-2, FB-2, S-4, E7-A, F-7, SD70ACe, ES44AC, GP30, GP38-2, GP40, GP7, RS-3, and SD40-2.

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 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.
