Dynamic Digital Exhaust Configuration

Dynamic Digital Exhaust (DDE) is an amazing new feature in Tsunami2 Digital Sound Decoders that will make your railroad more realistic than ever. DDE varies the prime mover notch and volume up and down based on how hard your locomotive is working. The feature can be automatically calibrated in your Diesel, Steam, and Electric decoders. Watch as George shows you the process of configuring this great new feature in a SoundTraxx Tsunami2 equipped model.
