Now you can have the best Digital Sound in those hard-to-fit HO diesels! Tsunami provides waves of pure 16-bit digital sound that will delight your senses; with effects so amazing you won't believe your ears. These Digital Sound Decoders are designed to replace the light board that comes in Atlas HO Diesel engines and many other popular diesel models. Since Tsunami comes with airhorns appropriate to the prototype, no special software or programmer is necessary to achieve the absolute best sound available.

Tsunami integrates a full-featured sound system, Hyperlight lighting effects, a motor controller and a DCC decoder into a single, integrated package and is compatible with the NMRA DCC standards and Recommended Practices. Unlike the DSD-150, the Tsunami sound system can also be used on ‘Analog’ layouts and controlled with a conventional power pack, though it really shines on DCC controlled layouts.

At Tsunami’s core is a true 16-bit Digital Signal Processor, or DSP, capable of executing over 120 million instructions per second. With this new level of performance, SoundTraxx was able to give Tsunami 14 functions, over 22 individual sounds, and 4 special effects including the ability to alter the exhaust sound automatically in response to changes in the engine load. The motor controller received numerous enhancements as well, including the use of high frequency PWM and load compensation. To keep the size down, only components available in highly miniaturized packages were selected for use in the Tsunami resulting in a form factor that measures almost 30% shorter and 50% thinner than the DSD-150.

The SoundTraxx Tsunami Digital Sound Decoders are compatible with the NMRA Standards and Recommended Practices.
