The Soundtraxx Tsunami Medium Steam (Micro TSU-750 Version)


The Micro-Tsunami TSU-750 sound system is SoundTraxx’s new high-performance, onboard locomotive sound system.
Like the Larger scale version (the TSU-1000), the Micro-Tsunami integrates a fully-featured sound system, two Hyperlight lighting effects, a motor controller and a DCC decoder into a single, integrated package which 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 of course, 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 of 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:

25mm L x 13mm W x 5.6mm thick
(1.00"L x 0.50"W x 0.22" thick)


More information:

Multiple Whistles- Each Tsunami includes several horn and whistle selections within each model making it easier to select the right sound of your favourite model. For example, the Southern Pacific 4449 will have an air horn too!

Short Whistle (or Horn) - To supplement the primary whistle, a short whistle control has been added to produce a short, snappy toot needed for many common whistle signals.

Dynamo (steam) - The dynamo sound effect has been improved to include the sound of the turbine windup when it is first turned on.

Brake Squeal - This effect has been added to both steam and diesel models and may be activated manually using a function key or automatically when the engine is slowed to a stop.

Water Stop (steam) - 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, cylinder cocks, snifter valves, brake release, side rod clank, Johnson bar/power reverse, blower, injector, pop valve and Fireman Fred. Diesel versions include engine startup, engine shutdown, dynamic brakes, poppet valve, aircompressor, radiator fans, bell and more.
