openings it may be possible to use the entire tender body shell as a sound chamber. A simple
wall behind the speaker may be all that is possible or perhaps all that is needed.
Speakers can be attached with double sided tape, with glue, or with "hot melt". Enclosures can
be made with plastic, wood, card stock, or even metal. Film cans or medicine bottles make
excellent sound chamber enclosures for small diameter speakers. Attachment with "hot melt" is
advantageous as the "hot melt" can be used as a gap filler when creating an enclosure.
A second speaker, wired in series with the main speaker, can also enhance sound quality and will
permit a higher volume without damage to the individual speakers.
Speaker enclosure is an art and experimentation is definitely in order for your installation so as to
gain the maximum benefit of the superb sound quality available in this sound system. Sometimes
a cluster of four smaller speakers will fit better and produce very acceptable sound versus a
larger speaker that may not fit very well.
GENERAL OPERATING INFORMATION:
VOLUME ADJUSTMENT: should be set as desired for your application. Please remember that
the amplifier can produce more power than a small speaker can handle and that the sound will be
louder if the speaker is properly enclosed and baffled. If you are using batteries, the louder the
volume the shorter the battery life.
SPEED SET control adjusts the sensitivity for run/stop operation of the sound system. Rotate the
control CCW to increase the voltage sensitivity. Use the unit in this mode, full CCW, for all 12 volt
DC systems. For higher voltage systems, turn the control more CW. For 20 volt and higher DC
and ALL AC systems, turn the control full CW.
SOUND FEATURES: Another feature incorporated in this sound system is the ability to turn all
sounds off, leaving only the Whistle and Bell to operate on the main unit and no exhaust chuff
from this unit. This can be done with the LocoMatic™ Controller by using the ALT & SF4 button
and is a push on / push off function. Other operators can access this with using function / switch
inputs.
DUAL SYSTEMS: This system can be used with another DC, LocoMatic™, or other AC type
sound systems. Wiring for each type of system must be followed to avoid any premature damage.
If one speaker is desired, an auxillary amplifier must be used such as item #671 or #672. Wiring
for use with one of these amplifiers is contained with the amplifier instructions.
NOTE: The speaker impedance should be kept near or above 8
ohms, therefore four 8 ohm speakers in a series/parallel
configuration is acceptable since it yields 8 ohms total
impedance. If you care to use two 8 ohm speakers you must
place them in SERIES.

When connecting DC power to the sound unit be absoloutly
sure that the "+" and "–" are connect correctly! If not, you
will either burn out the sound unit or the supply feeding it.
