TSU-AT1000 Digital Sound Decoder™

Plug and Play Digital Sound Decoder for HO Diesels

Now you can have the best digital sound in those hard-to-fit HO diesels! Tsunami provides waves of pure 16-bit digital sound that will delight your senses; with effects so amazing you won't believe your ears. These Digital Sound Decoders are designed to replace the light board that comes in Atlas HO diesel engines and many other popular diesel models. Since Tsunami comes with 16 airhorns appropriate to the prototype, no special software or programmer is necessary to achieve the absolute best sound available!

Tsunami's sound features are matched only by its superior motor control and brilliant lighting effects, making it unsurpassed in its technological capabilities. A 16-bit Digital Signal Processor provides the necessary horsepower Tsunami needs to support more functions, sound effects and advanced motor control than ever before!

BIG Sound Features

The TSU-AT1000 is available in a variety of prime movers to suit nearly every diesel prototype. Tsunami Diesel decoders can produce over 14 sound effects, including engine startup and shutdown, engine prime mover through all eight notches, bell, airhorn, air compressor, dynamic brakes, radiator fans, brake squeal, and more.

Tsunami goes several steps beyond ordinary sound generators. Tsunami is so powerful that it comes with its own special effects processors - the Equalizer, Sound Mixer, and Reverb. It's like having a complete sound studio at your fingertips.

Brilliant Lighting Effects

Tsunami includes four outputs for SoundTraxx's Hyperlight lighting effects to reproduce the most popular warning beacons. A special added feature - hardware is already on the circuit board to accommodate the easy use of 1.5 volt bulbs without the need for external resistors.

Advanced Motor Control

SoundTraxx has designed Hyperdrive™ technology into the decoder, resulting in smooth and precise locomotive operation. Hyperdrive includes many features, such as high-resolution speed steps, high-frequency PWM drive, and torque control, all designed to improve the running characteristics of your locomotive.

Prototypical Operation

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