The Tsunami2 TSU-21PNEM8

The TSU-21PNEM8 is a 1-amp Digital Sound Decoder with 8 function outputs. It is designed for easy plug-in operation when mated to a 21-pin NEM connector. You will feel like you are in the cab with the amazing new features that Tsunami2 has to offer 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: exhaust chuffs(10), prime movers (up to 12), bells (12), Whistles (90), airhorns (40+), couplers, dynamos and more!

Need Help Choosing a Sound Profile?

We have tons of sounds to match a wide range of locomotives. So many, in fact, we cannot fit them all on one decoder. Therefore, they are broken up into sound profiles of like sounds (Steam, EMD, GE, Electric, etc.). If you don't know which sound profile you need, the best place to start is the Sound Selection References. These will list all the prime movers or exhaust chuffs available on each sound profile. If you need further assistance explore these links:

• Decoder Selector: Tells you which board format and part number you need for specific models.
• Sound Samples: Hear our sounds in action!
• Choosing the Right Sound System: If you are new to SoundTraxx, model railroading, or are unfamiliar with our products.
• Sound Selection References: There are several for each decoder and they can be found below or in the Manuals section of our website.

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.

HIGH QUALITY SOUND LIBRARY

Our large selection of high quality sound effects include:

• 10 Exhaust Chuffs
• Up to 12 Prime Movers in each sound profile
• Up to 12 Bells
• 90 Whistles
• 40+ Airhorns
• Additional couplers, dynamos, cab chatter and more!
• ADDED REALISM
• Additional realism can be simulated by adding functioning locomotive and train brakes, injectors, power reverse, firebox flicker and more.

EASY INSTALLATION

The TSU-21PNEM8 simply plugs into models equipped with a 21-pin NEM connector.

The TSU-21PNEM8 can be wired to a CurrentKeeper (P.N. 810140 or 810160) to maintain performance over dirty track and switches.
