later in this manual. The sound itself is a stored record on the
ProtoSounds® software chip and will always play the same brake sound for
the same three second length each time the voltage is reduced from high to
low. Some practice may be required to synchronize the playing of the brake
sounds with the movement of the engine. It is not uncommon for the engine
to stop before the brake sound is completed. Operators will find that by
coordinating the movement of the throttle setting from 8 volts to off will
allow the engine to maintain its movement while the brake sounds play.
Note: The brake sounds will not be heard if the transformer throttle is not
set above 14 volts and/or not reduced below 8 volts.
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 determine how quickly to throttle down and at 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® squeaking 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 squeaking sound plays, but you don’t need to reduce the
transformer throttle to activate the squeaking sounds. To play the squeaking
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) quickly
“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.
