Welcome to the SoundTraxx Decoder Selector! This section will
assist you in selecting the correct decoder and bill of materials
for installing a SoundTraxx Tsunami Digital Sound Decoder in your locomotive.
Simply click on the scale of your locomotive, then the manufacturer, and finally your specific model. Please note:
Models with the initials "NA" listed under the speaker/baffle
column come with a factory-installed speaker and baffle. Models that have "Not Available"
listed under the speaker/baffle column require a speaker or
baffle that we don't currently offer.
We have also added Application Notes with some of our decoder recommendations. These are ranked by difficulty level and provide step-by-step instructions for installation, as well as a comprehensive bill of materials. Model descriptions highlighted in blue indicate a link to an Application Note. This is an ongoing improvement, so if you don’t see an Application Note for a particular model, please check back from time to time.
