Blunami will change the way you enjoy the model railroading hobby! The BLU-2200 is a universal-style sound decoder that can be operated in three different ways: DC, DCC, and Wireless mode. Using the Blunami App, you can operate your locomotive incredibly easily. This decoder is suitable for use in both HO and small S-scale models.

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.
For added realism, you’ll love our 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. 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 create the most realistic experience possible.

Our large selection of sound effects includes:

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!
Additional realism can be simulated by adding functioning locomotive and train brakes, injectors, power reverse, firebox flicker, and more.

The BLU-2200 can simply plug into models equipped with a DCC quick plug. Our 9-Pin JST to NMRA 8-Pin Wiring Harness (P.N. 810135) can also be used to plug the BLU-2200 into models equipped with an NMRA 8-Pin plug. The BLU-2200 can also be wired into a large variety of models.

This 2-amp, universal-style format includes a connector to easily add a Current Keeper (P.N. 810140 or 810160) to maintain performance over dirty track and switches.
