Need Help Choosing a Sound Profile?
We have tons of sounds to match a wide range of locomotives. So many, in fact, we cannot fit them all on one decoder. Therefore, they are broken up into sound profiles of like sounds (Steam, EMD, GE, Electric, etc.). If you don’t know which sound profile you need, the best place to start is the Sound Selection References. These will list all the prime movers or exhaust chuffs available on each sound profile. If you need further assistance explore these links:

• Decoder Selector: Tells you which board format and part number you need for specific models.
• Sound Samples: Hear our sounds in action!
• Choosing the Right Sound System: If you are new to SoundTraxx, model railroading, or are unfamiliar with our products.
• Sound Selection References: There are several for each decoder and they can be found below or in the Manuals section of our website.
