Tsunami Sound System is a SoundTraxx high-performance, Digital
Sound Decoder. Tsunami
integrates a full-featured sound system, lighting, a motor controller
and a DCC decoder into a single, integrated package and is compatible
with the NMRA DCC standards and Recommended Practices. Although the
Tsunami sound system can also be used on ‘Analog’ layouts and
controlled with a conventional power pack, 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 2 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.
Sounds
Some of the many
sound effects in the Tsunami repertoire include:
Multiple Whistles- Each steam Tsunami will offers several whistle
selections making it easier to select a sound you like.
Short Whistle - To
supplement the primary whistle, the short whistle control produces a
short, snappy toot needed for many common whistle signals.
Dynamo - The dynamo sound effect includes the sound of the
turbine windup when it is first turned on.
Brake Squeal - This
effect may be activated manually using a function key or automatically
when the engine is slowed to a stop.
Water Stop - The water stop effect can be activated with a
function key whenever the engine is stopped and begins with the sound of
the tender hatch being opened followed by the sound of water filling the
tender.
In all, there are over 22
steam sound effects including the bell, air pump, exhaust chuff,
coupler, steam release, snifter valves, brake release, side rod clank,
Johnson bar/power reverse, blower, injector, pop valve and Fireman Fred.
More Functions = More Fun!
To help control all these sounds, Tsunami will
respond to up to 14 function keys. Tsunami’s function mapping feature
can always be used to change the control configuration to suit one’s
personal taste.
Sound Effect Processor
Tsunami has four built-in sound effects that allow
the individual sounds (i.e., whistle, bell, etc.) to be modified in a
particular manner. Each effect is fully adjustable using the decoder’s
CV settings and each effect can be turned on or off as desired.
Mixer
Tsunami’s mixer design incorporates several new
innovations. To begin with, there are 24 individual volume settings
allowing each sound effect level to be independently adjusted. A master
volume control has also been added so that the overall audio level can
be easily changed with a single CV. Finally, the mute function has been
improved to provide a more pleasing fade-off/fade-on effect
Dynamic Digital Exhaust Processor (DDE)
The DDE
processor senses changes in the throttle setting, and automatically
adjusts the timbre, volume and other parameters of the exhaust sound to
simulate what would be heard from a prototype locomotive under similar
conditions.
Reverb
A digital reverb has been included in the Tsunami
system to add “spatial presence” to selected sound effects. By
adjusting the reverb level and delay time, the user can simulate
multiple prime movers for example, or the effect of operating in hilly
terrain.
Multi-Band Equalizer
Each Tsunami sound system incorporates a multi-band
equalizer similar to the “graphic” equalizer found on many of
today’s home and automotive stereo systems. Tsunami’s equalizer
allows the user to cut and boost sound levels by +/- 12dB over seven
selected frequency ranges (62Hz, 125Hz, 250Hz, 500Hz, 1KHz, 2KHz and
4KHz) and provides the “ultimate” tone control.
Hyperdrive
Motion Control System
Tsunami’s motion controller incorporates all of
the most advanced motor control features found in the DCC marketplace
today plus a few new ones:
High Resolution Speed
Steps
While most decoders today can support 127 speed
steps, Tsunami has 2048 speed steps! Admittedly, there are no DCC
systems on the market as yet supporting this many speed steps; however,
Tsunami interpolates between speed steps during acceleration and braking
and as part of its load compensation algorithm. The result is micro-fine
speed control regardless of the speed step mode selected on the DCC
system.
High Frequency PWM Drive
Virtually all DCC decoders used a form of PWM
(Pulse-Width-Modulation) to control motor speed, At low frequencies, the
PWM signal used to control the motor speed can result in an audible hum
or buzz. To mitigate this problem, Tsunami uses an ultra-sonic PWM
frequency adjustable to 39KHz, well beyond the range of human hearing
and safe for coreless motors as well.
Speed Curves
Like all other SoundTraxx decoders, Tsunami provides a
user-customizable speed table and an adjustment for starting voltage as
well as 14 preset speed curves.
Adjustable Momentum
The acceleration and braking rates are independently adjustable and can
be used to simulate the momentum of a heavy train. Additionally, in the
event of a sudden direction change, Tsunami will first slow the motor to
a full stop before changing directions and then accelerate back to the
original speed.

Hyperlight
Lighting System
In addition to
headlight and backup light, Tsunami also has an effect for steam
locomotives called the “Dyno-Light” which synchronizes the lamp
brightness to the “output” of the dynamo such that the lamp
brightness gradually increases as the dynamo builds up speed.
