TSU-GN1000 Digital Sound Decoder

Plug and Play Digital Sound Decoder for Athearn Genesis HO Diesels

The TSU-GN1000 Digital Sound Decoder provides the best digital sound for your coveted Athearn Genesis HO diesel models. These Tsunami Digital Sound Decoders are designed to replace the light board that comes in recent production Athearn Genesis HO diesel engines. 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 32-bit dgital signal processor provides the necessary horsepower Tsunami needs to support a multitude of functions, sound effects, and advanced motor control features.

Big Sound Features

The TSU-GN1000 is available in a variety of prime movers to suit your Athearn Genesis diesel model. 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 our Hyperlight lighting effects to reproduce the most popular warning beacons. A special added feature -- hardware is already on the circuit board to accommodate the use of 1.5 volt bulbs without the need for external resistors.

Advanced Motor Control

We 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 activate lighting effects. The more functions your controller has, the more fun you'll have!
