M.T.H. Proto-Sound 3.0 Installation Manual page 29

STEP 1:
The Proto-Sound 3.0 upgrade kit utilizes a Proto-Sound 3.0 Diesel/Electric
board that uses Proto-Sound 3.0 sounds. To find a Proto-Sound 3.0 file, go to
www.mthtrains.com and select "Service". Then select "Proto-Sound Files" from
the available options.
Select "Service"
STEP 2:
Search using the general engine type,
such as SD70.
Refine the search by selecting the
Product Line, or the Road Name
desired. (Note: You may have to use
another road name or product line -
RailKing vs. Premier - for the
upgraded engine.) If you do not find
a sound set with the appropriate
product line or road name, select the
best sound for the locomotive.
Since most Diesel/Electric models
use a standard wheel diameter and
gear ratio, RailKing and Premier
sound files can be used
interchangeably without effecting the
speed. (Note: Premier engines
usually have more lighting options.)
