Doppler Loop
This feature allows you to set the Doppler effect to play every time the programmed engine
passes a certain point on your layout. M.T.H. sound engineers measured this for a scientifically
accurate Doppler pitch change: the growing and fading of the sounds are exactly what a scale
person would hear as a scale train passed by.
1. Place the engine at the location on the layout where you want the sound to peak during Dop-
pler sound. Tap the Doppler Menu under the Sound settings screen and tap Doppler Loop Start
to tell the engine to begin measuring its Doppler loop. Run the engine around the loop.
2. Stop the engine at the exact same location on the layout where you started. Tap the Doppler
Menu icon under the Sound Settings screen, then tap Doppler Loop Stop to stop measuring the
loop.
3. To operate your Doppler Loop, make sure the engine is where it was when you started, tap
Doppler Repeat, and run the engine like normal. The sound effects will fade out as you pull
away from the peak spot on your layout and will swell as you round the circle and return to
the peak spot. The locomotive will continue to operate in consecutive Doppler cycles until you
select Exit Doppler Loop from the Doppler Menu.
NOTE:
Because there is no Global Positioning for model trains, the Doppler system measures
distance, not location on a layout. You must begin and end your setting and begin operation
at the exact same point on the layout, or the mis-measurement will cause the Doppler peak
location to move over time. For instance, if you stop programming the loop 5 inches short of
where you started, the loop will be five inches short of your layout’s full route, and the Dop
-
pler peak will move by five inches on every trip around the layout.
