TIPS ON USING THE SQUEAKING BRAKE FEATURE
Because the squeaking brake feature always plays for approximately 3
seconds, it is possible that the brake sounds will play longer or shorter than
what visually seems prototypical. You will find that by practicing with the
brake feature, you can quickly determine how quickly to throttle down and
what speeds and voltage settings give you the most prototypical braking effect.
Typical users will find the feature to be a very realistic way to simulate the
sound of an engine slowing down for curves, crossings or coming to a stop at a
station, side track or switch yard. As mentioned above, you will find that
initially your engine may continue to play the brake sounds once your engine
comes to a stop or that the sounds stop prematurely before the engine comes to
a complete halt. For example, if you simply run the engine and turn the
throttle off quickly, the brake sounds will likely continue playing even though
the engine has come to a complete stop. This annoying effect can be
eliminated by simply practicing with the brake feature. In no time, you will
quickly learn how to “feather" the throttle to keep the engine moving while the
brake sounds play and then turning the throttle off just as the sounds stop.
Remember that once you stop the engine, you should turn the throttle to the off
position if you don’t want to activate the Passenger Sounds feature described
later in this manual.
The ProtoSound squealing brake feature also has the ability to simulate the
squeal of wheel flanges when your train enters a curve at high speeds. The
same brake squealing sound plays, but you don’t need to reduce the
transformer throttle to activate the squealing sounds. To play the squealing
sounds as wheel flange sounds, trigger the brake feature using either method 1
or 2 above. Once triggered set the transformer throttle setting at 14 volts or
higher. As your engine enters a curve (or anywhere on the layout) quicky
“flick" your transformer whistle button about half way. This “flicking" action
causes the transformer to release a short DC signal that ProtoSounds reads as
an indicator to activate the brake sounds. The engine won’t slow down even
though the sounds play. This simulates the wheel flange squeal of a train
traveling through a turn too quickly.
Note: Consistent activation of the wheel flange squealing is determined by the
condition of your transformer’s whistle button rectifier disc. Older rectifier
discs may need to be replaced in order to play squealing sounds.
