SoundTraxx brings new dimensions in digital sound technology to your model railroad. Regardless of your scale or prototype, they have a sound system for you! They manufacture all of their Digital Sound Decoders in the USA, right here in Durango, Colorado. Their professional sound engineers record and edit their sound files and test their decoders multiple times before they ship to ensure top quality.
Easily adapt any SoundTraxx 21PNEM decoder to an NMRA 9-Pin DCC “quick plug” equipped model. This adapter can also be used with SoundTraxx 9-Pin JST power harness (STX810069) to create a universal-style decoder. Dimensions: 22.5 x 16 x 7.5mm Support for up to 8 functions Solder Pads for CurrentKeeper, speaker connections and extra lights More Information Browse all DCC speakers and DCC wiring, shop the full SoundTraxx range, or pick a decoder from our DCC decoders.

FAQ Will this fit my locomotive?It measures 30.5 x 15.5 x 6.5mm and connects by 21-pin nem (21mtc) plug. Check that against the space in your shell before ordering — other Tsunami2 versions use different connectors and sizes. Is a speaker included?No. Pair it with an 8-ohm speaker rated 2 watt or better that fits your shell. Which prime movers do I get?All 9 listed above, selectable via CV 123. You are not locked to one engine sound — pick whichever matches your prototype. Does it run on DC?Yes. Tsunami2 runs on a standard DC power pack as well as DCC, though sound and lighting options are limited on DC. Full function control needs a DCC system.
