Like the DSD-150 it replaces, Tsunami integrates a full-featured sound system, four 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 32-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.
