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.
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.
CHUFF RATE control adjusts the rate of chuff when in auto-chuff mode. This adjusts the
maximum chuff speed for voltage variable automatic exhaust chuff. Rotate the control CCW to
increase the voltage required to reach maximum chuff speed. Adjust as desired for a chuff rate to
match your locomotive. With synchronized exhaust chuff, the CHUFF RATE control adjusts the
chuff pitch. This is more noticeable at higher track voltages and allows you to "tune" the chuff.
Another feature incorporated in this sound system is the ability to turn all sounds off, leaving only
the Whistle and Bell to operate. This can be done with the LocoMatic™ Controller by using the
ALT & F4 button and is a push on / push off function. Other operators can access this with using
function / switch inputs.

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.
This is not covered under warranty!
Common Whistle signals
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!
J3 connections:
1 - track RF input (RED)
2 - Motor 1 (BLACK)
3 - Motor 2 (WHITE)
J1 connections:
1 - DCC rail 1 ....... also AC input 1 ......... (RED)
2 - DCC rail 2 ....... also AC input 2 ......... (GRAY)
J2 connections:
1 - DC power "+" (RED)
2 - DC power "–" (GRAY)

Stationary use options:
1 - small DC power supply, item #689, to power the
sound system from 120VAC.
2 - large DC power supply, item #604, for use with
amplifier and sound system from 120VAC.
3 - Item #603, parts to make your own DC power
supply from a fixed AC transformer (item #690).
This includes components for power supply, a
push button switch for the Horn, two toggle switch
for the Bell operation (other switches are sold
seperatly). Two potentiometers with knobs and
parts to make all connections as on page 9.
