Tsunami2 Digital Sound Decoders integrate a full-featured sound system, Hyperlight™ lighting effects, Hyperdrive2™ advanced motor control, and a DCC decoder into a single package. Tsunami2 Digital Sound Decoders offer over 50 individual sounds and over 20 lighting effects in each model! We have added a host of new recordings including: whistles, horns, bells, compressors – and remastered favorites from years past. These new recordings provide nearly limitless choices to the user! Multiple prototypes in every model means no time spent on a computer downloading files or purchasing special programs. In addition, more powerful audio output, two volume mixers and our ever-popular Equalizer make the digitized recordings of real engines loud, clear and ultra-flexible. In 1996, SoundTraxx first introduced Dynamic Digital Exhaust to modelers. Now, we’ve taken this cool feature to new levels of prototypical realism. Tsunami2 is equipped with our newly designed Dynamic Digital Exhaust (DDE), which automatically adjusts the volume and engine RPM schedule to simulate the locomotive producing a range of power during operation. Engine RPM increases as the DDE processor detects greater amounts of demand on the motor, and it reduces as the demand is lifted. In 2005, SoundTraxx introduced the first “F11” Braking Feature. Tsunami2 takes this even further with three different types of braking – Independent, Train and Dynamic Braking – allowing you to truly be in the engineer’s seat! Add HEP mode (Head End Power) in diesel versions and the first truly adjustable steam cut-off, and you’ll discover a whole new way to have fun with your trains! Hyperdrive2 provides incredible low-speed operation and smooth, lurch-free running with a switching mode that will reduce the speed by half – at the press of a key! Tsunami2 provides full 28-function support and includes our newly developed Flex-Map technology. This makes assigning any functionor sound effect to any key easy and intuitive. Tsunami2 Digital Sound Decoders are designed for installation insideyour locomotive and are available in steam, diesel or electric versions each featuring a full spectrum of prototype-specific soundeffects. It is compatible with the NMRA DCC Standards and Recommended Practices.
