Soundtraxx Tsunami® Diesel 827115  – TSU-1000 EMD 710G3C-T2 (SD70ACe)

The Tsunami TSU-1000 is SoundTraxx’s high-performance, onboard locomotive sound system. The TSU-1000 is a versatile 1 amp decoder integrating a full-featured sound system, four outputs for using Hyperlight™ lighting effects, motor control, and a DCC decoder into a single, integrated package. It is compatible with the NMRA DCC Standards and Recommended Practices.

The TSU-1000 is designed in a one-size-fits-all format to fit a large variety of steam and diesel models. To keep the size down, only components available in highly miniaturized packages were selected for use in the Tsunami. The TSU-1000 measures 33mm x 17mm x 6.5mm (1.68” x 0.68” x 0.25”). Two removable wire harnesses provide connections for power, lights, and speaker(s). The TSU-1000 is especially flexible for installation in older brass and pre-DCC-ready models. An 8-pin NMRA connector can be wired to the power harness to make it a ‘plug and play’ decoder.

Tsunami TSU-1000 can also be used on ‘analog’ layouts and controlled with a conventional power pack, though it really shines on DCC-controlled layouts.

Unlike other manufacturers who hide behind words like ‘CD quality’ or ‘Co-processor technology’, Tsunami is truly a 16-bit digital sound system – the best available on the market. 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.

Tsunami goes several steps beyond ordinary sound generators. Tsunami is so powerful that it comes with four special effects processors – the Equalizer, Sound Mixer, Dynamic Digital Exhaust, and Reverb. It’s like having a complete sound studio at your fingertips!

Tsunami steam decoders can produce over 22 sound effects, including the bell, whistle, airpump, dynamo, snifter valve, injectors, firebox blower, side rod clank, brake squeal, exhaust chuff and more. Pull up to the water tank and activate the Water Stop effect – a steam engine won’t get far without water! Fireman Fred has a few new things up his sleeve as well, as he works to keep the locomotive in prime operating condition.

Use the Auto-Exhaust™ feature to adjust the exhaust cadence to correspond to a 2-cylinder, articulated or geared locomotive, or use a cam if you prefer.

Tsunami desel decoders can produce over 14 sound effects, including the engine startup and shutdown, engine prime mover through all eight notches, bell, airhorn, air compressor, dynamic brakes, radiator fans, brake squeal and more.

Advanced Motor Control

SoundTraxx has designed Hyperdrive™ technology into the Tsunami TSU-1000, resulting in smooth and precise locomotive operation. The motor controller compromises nothing, and includes the use of high-frequency PWM and load compensation. In addition to these features, Hyperdrive includes high-resolution speed steps and torque control, all designed to improve the running characteristics of your locomotive.

Brilliant Lighting Effects

Tsunami TSU-1000 decoders include four outputs for SoundTraxx’s Hyperlight lighting effects, which reproduce the light patterns of many popular warning beacons in exacting detail. All Tsunami decoders provide “Rule 17” lighting control. Now you can independently turn on the headlight and backup light, as well as dim the lights for oncoming trains.

Prototypical Operation

With the press of a key on your DCC controller, you can blow horns and whistles, ring the bell, and watch the headlight sputter to life as the power builds up. The more functions your controller has, the more fun you’ll have!
