Why is M.T.H. offering the Proto-Sound 2.0 Conversion when in the past the company claimed that an upgrade program wasn feasible?
As with all electronic goods, circuit boards are typically refined and improved throughout the lifespan of the product. The maturation of Proto-Sound 2.0 is no exception and a more capable design was created in late 2002 for our RailKing One-Gauge locomotives that allowed for use on both AC or DC current. More importantly, the new design provided a standard memory system so that all variations of M.T.H. Proto-Sound 2.0 equipped locomotives could function. Proto-Sound 2.0 has three different types of processor software configurations for standard steam or diesel locomotives, trolley/street car/subway units and articulated steam engines. The multiple processor memory configurations required in the past for the different Proto-Sound 2.0 locomotive types would have made the Proto-Sound 2.0 conversion much more difficult. In addition, the board now utilizes an advanced two-part design which reduces the amount of heat dissipation required in the earlier circuit. Such a configuration greatly
