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. A tube with a speaker at each
end or a speaker in a doorway at each end of a body shell is an excellent approach. A four speaker
approach will yield the highest volume while still maintaining the 8 ohm minimum requirement.
Drawings for this are included in the speaker instructions.
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.
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.
NOTCH ADJUSTMENT: full clockwise will yield notch #8 on the diesel at approximately 8 volts to
the track / motor. Rotate the control CCW to increase the voltage required to reach notch #8.
Gauge 1 and other operators using higher motor voltages will probably want to set this control full
CCW.

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.

Diesel Sound systems .
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.
This is not covered under warranty!

This system features an optically coupled motor
input sensor. This means that any connection to
J3 pins 1, 2, and 3, do not electrically connect
to any other power to the board!
