Before Proto-Sound 2 there was Proto-Sound 1. Here you will find descriptions and help files related to the systems that came before. MTH hasn't forgotten the inovations that lead to the amazing technology in model trains today.

Original Proto-Sound

Original Proto-Sound® is a complete CD-quality digital sound and train control system. Proto-Sound uses a computer system to program and activate sound packages and train control features, and it requires no additional equipment to a layout.

M.T.H.'s all-new Loco-Sound system brings realistic digital sound and basic train control to inexpensive train sets and engines. It is perfect for the beginning model railroader or people on a budget.
