SoundTraxx brings more FUN to your model railroad through the magic of sound! Regardless of your scale or prototype, we have a sound system for you! We manufacture all of our digital sound decoders in the USA, right here in Durango, Colorado. Our professional sound engineers record and edit our sound files and test our decoders multiple times before we ship to ensure top quality.

You asked and now it is here! Our newest Blunami board format is the BLU-PNP8. This is a universal factory board replacement sound decoder suitable for use in many manufacturer’s HO diesel models. It offers an easy installation procedure, 8 function outputs, and a 2-watt audio amplifier.

Large scalers rejoice! The BLU-4408 opens the door to onboard battery power for large-scale models with SoundTraxx decoders. It also boasts 8 function outputs and a 4-watt audio amplifier. The Blunami App eliminates the need for a command station or CVs when running your trains.
