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

The Micro-Tsunami TSU-750 sound system is SoundTraxx's new high-performance, onboard locomotive sound system. Like the TSU-1000, the Micro-Tsunami integrates a full-featured sound system, two 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. The Micro-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. This "micro" decoder will fit into most HO and many N scale locomotives, and is rated for a stall current 0.75 Amps. 

At the Micro-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 the Micro-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. Only components available in highly miniaturized packages were selected for use in the Micro-Tsunami resulting in a form factor that measures 1.00"L x 0.50"W x 0.22"H.
