Tsunami2 TSU-N18 Digital Sound Decoders combine high-quality, digital sound and the benefits of today’s Digital Command Station (DCC) technology with a convenient N18 socket connection. SoundTraxx has made the footprint of the TSU-N18 even smaller giving it the ability to fit into an even greater range of N-Scale narrow body locomotives. The small size of our TSU-N18 decoder makes it ideal for both N and small HO models that come equipped with a NEXT18 socket. Installations can’t get any easier. Simply plug this decoder in and enjoy all of the Tsunami2 features you know and love!


Coupled with the new SoundTraxx JST-Next18 Adapter kit (P.N. 810163), the TSU-N18 becomes a smaller, universal-style option than the TSU-1100 and allows you to easily install into non-N18 equipped models.


Installs can't get any easier, the TSU-N18 simply plugs into models equipped with a NEXT18 socket. The TSU-N18 can be wired to a CurrentKeeper (P.N. 810140 or 810160) to maintain performance over dirty track and switches.
