MSRP: $119.00  Our Price:  $101.99

The Tsunami TSU-1000 is SoundTraxx’s high-performance, onboard locomotive sound system. It's a versatile 1 amp decoder integrating a full-featured sound system, four outputs for using special lighting effects, motor control, and a DCC decoder, all in an integrated package. Complies with NMRA DCC Standards and Recommended Practices.

The TSU-1000 is designed as a one-size-fits-all to fit a large variety of steam and diesel models. The TSU-1000 measures 43mm x 17mm x 7mm (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.

Tsunami's sound features have superior motor control and lighting effects.  It's unsurpassed in its technological capabilities. A 32-bit digital signal processor provides  a multitude of functions, sound effects, and motor control.

Because of the design and placement of the lights in these models, each decoder is manufactured to suit a particular model rather than prototype.
