The SoundTraxx Tsunami2 Electric TSU-886803 is a premium 21-pin (NEM660) DCC sound decoder built specifically for electric locomotives such as electrics, interurbans, and other overhead-wire prototypes. It combines SoundTraxx Tsunami2 sound quality, smooth motor control, and 8 function outputs for flexible lighting and onboard effects.
Realistic Tsunami2 Electric Sound
This decoder is part of the Tsunami2 Electric series and is designed to reproduce the distinct audio you expect from electric power, including appropriate electric locomotive sound effects and operating behaviors. If you are modeling electric prototypes and want sound that matches the equipment, the TSU-886803 is the right fit.
21-Pin Plug-and-Play Installation
The TSU-886803 uses a 21-pin NEM660 interface for direct installation into compatible locomotives equipped with a factory 21-pin socket. This makes it a clean upgrade path for many modern DCC-ready models without hard-wiring.
8-Function Lighting & Effects Control
With 8 function outputs, you can control headlight and rear light functions plus additional lighting effects such as cab lights, marker lights, number boards, beacon effects, and other custom lighting behaviors (depending on your locomotive and motherboard support). Functions are fully configurable using CV programming.
