Decoder - Sound

Digital Sound Decoders are designed to be installed onboard your model with a speaker to provide sound that comes from the locomotive itself. A sound decoder is a computer on a chip that receives and interprets signals sent from the DCC base station and puts out an analog signal that makes an attached speaker produce the sound desired. Many top sound decoder manufacturers and brands include Soundtraxx Tsunami2, ESU LokSound, TCS Wow Sound, and Digitrax sound decoders. DCC sound decoders have a wide variety of uses that offers model railroaders the ability to enhance their locomotives, rolling stock, and layouts with a range of sounds, deepening the realism and impact of their layouts.
