SoundCar Digital Sound Decoder

Your train is no longer limited to locomotive sounds! The 16-bit, universal-style Tsunami SoundCar Digital Sound Decoder is the only DCC decoder to replicate railcar sounds and lighting effects. It also includes a selection of user-adjustable horns, bells and whistles for cab cars and cabooses. For even more realism, the decoder has four Hyperlight lighting outputs for interior and exterior lights.

These decoders are easy to install in N to G scales. They work with any 8-ohm speaker.  For the optimal experience, use a SoundCar decoder in every third or fourth car in a consist.

The SoundCar also includes a 2-pin plug for optionally using the SoundTraxx CurrentKeeper™ to maintain sounds and lights during momentary power losses due to finicky wheel pickups and not-so-perfect track.


It is important to choose a capable speaker to use with these decoders. Below you will find a list of speakers that are compatible with the Tsunami SoundCar Digital Sound Decoder.
