can be totally destroyed). Damage resulting from loose wire or other metal making contact with
the circuit board or its components is also not covered under warranty. These sound systems are
thoroughly tested and inspected before packing to insure proper function. There is a minimum
charge of $50.00 (plus s/i, PA residents require sales tax) for non-warranty repair so please be
careful when making these power connections.
SOUND INFORMATION:
AIR PUMPS are needed to maintain air pressure in the train and locomotive braking systems.
These pumps must run periodically as pressure drops, due to brake applications or through
normal leakage. To simulate this action, AIR PUMP sounds are generated at random intervals
when the sound system is on and there is no power to the track / motor. AIR PUMP sounds will
also be heard when power is first applied to the sound system. This will give you an indication
that the system is in fact functioning.
BLOWERS are used on a steam locomotive to maintain fire box draft when the locomotive is not
in motion. BLOWER sound will be generated whenever the locomotive has stopped moving and
there is no power to the track / motor.
SAFETY VALVE will vent if steam pressure in the locomotive boiler becomes excessive. The
sound system will produce a SAFETY VALVE release at random intervals whenever the blowers
are on and steam is not otherwise being used.
CYLINDER BLOW DOWN is required to remove condensate that accumulates in the cylinders
when a locomotive has been at rest. This condensate must be exhausted from the cylinders prior
to the pistons being powered by steam or there can be damage to the cylinders. CYLINDER
BLOW DOWN sounds will be generated by the sound system when requested. With the
LocoMatic™ Controller you depress and release the ALT & F3 button to turn on the CYLINDER
BLOW DOWN and then again depress and release the button to turn the CYLINDER BLOW
DOWN off. A remote function control does not require the PUSH ON - PUSH OFF sequence. The
CYLINDER BLOW DOWN will automatically turn off after the locomotive starts running and an
appropriate number of exhaust chuffs have occurred with the ball cocks in the open position or
the engine starts moving too fast. During this motion, the Cylinder Blow Down can always be
turned off. After the engine is brought to rest, several seconds must elapse before this function
can be turned back on. After all, condensation takes a while to occur, so you wouldn't open the
ball cocks to blow the cylinder's out right after stopping.
WHISTLE sound is controlled by the WHISTLE button on the LocoMatic™ Controller or by
remote function, dependent upon the type of installation. The WHISTLE will sound as long you
are holding the control on. This will allow you to actually play the sound as on a real locomotive.
DCC and similar systems will have a sound delay equivalent to system response time.
BELL sound is controlled by the BELL button on the LocoMatic™ Controller or by remote
function, dependent upon the type of installation. When BELL sound is requested the sound
system will ring the BELL continuously. After a ring or two, the BELL can be turned off and will
stop at the end of a ring. With the LocoMatic™ Controller you depress and release the BELL
button to turn on the BELL and then again depress and release the button to turn the BELL off.
Remote function control does not require the PUSH ON - PUSH OFF sequence.
EXHAUST CHUFF is the most notable sound of a steam locomotive in motion. The sound is the
result of the used steam from the cylinders being vented through the stack. Each cylinder will
exhaust twice during each drive wheel revolution and since most steam locomotives have two
cylinders, the exhaust should chuff four times for each drive wheel revolution. EXHAUST CHUFF
sounds should vary from a very slow chuff rate to an almost continuous roar at high speed.
EXHAUST CHUFF should also vary as to the load on the locomotive with a heavy train making a
louder exhaust. This sound system will vary the EXHAUST CHUFF sound either by an OPTICAL
INPUT (Item #583 included) or optional switch contacts, with actual movement of the drive
wheels or other axles. Additionally, the EXHAUST CHUFF is dynamic and it's volume will
increase above normal during acceleration and will be lower when decelerating. Since the Y6A,
Y6B had both simple and compound operation, this is also included in this sound system. When

CAUTION-THIS DEVICE CAN BE DAMAGED BY STATIC DISCHARGE. PLEASE EXERCISE CARE DURING
INSTALLATION TO AVOID THIS POSSIBILITY. DISCHARGE YOURSELF TO AN ELECTRICAL GROUND (OUTLET
COVER SCREW) BEFORE REMOVING THIS DEVICE FROM ITS ANTI-STATIC BAG. PLEASE READ INSTRUCTION
SHEET COMPLETELY BEFORE ATTEMPTING TO INSTALL AND OPERATE THIS PRODUCT. Save the anti-static bag
for possible reuse of storing or shipping the sound unit!
OVERVIEW: This device is an electronic, self contained, polyphonic sound system for installation
in model steam locomotives that are designed to operate with conventional DC track power,
digital (DCC), other types of command control systems including radio with either track or battery
power. The sound system is limited to "O" scale and larger gauge models and may also require
the use of a trailing car. An on/off switch (Item #524, not included) must be used to turn the sound
unit on and off in some applications. If there is sufficient input power, the three audio amplifiers
can each produce 1.1 watts of audio power which is in excess of what most small speakers can
handle. The speaker impedance must be 8 ohms or higher. Sound volume, treble, and bass is
adjustable for each audio channel. Refer to our catalog for available speakers.
Sounds produced include user controlled steam whistle and bell, random air pumps, periodic
safety valve pressure release, cylinder blow down and steam exhaust chuff sound automatically
adjusted to speed and load conditions. Exhaust chuff must be synchronized to actual piston
movement, drive wheel or axle rotation.
This sound system, when used with conventional DC track power, requires the use of our
LocoMatic™ Controller (Item 755) to operate the whistle, bell, cylinder blow down, main sounds
on/off and other lighting features. DCC and other command control operators can use remote
functions on their systems to activate these functions. Radio control with fixed track power or on
board batteries would be similar to DCC installations.
INSTALLATION INSTRUCTIONS: The sound system consists of three printed circuit boards, and
multiple mating connectors with wires. A CHOKE (item 702 or 703 depending on motor power
requirements), not included, is required for DC track power installations.
Refer to the drawing on page 3 to familiarize yourself with the connections required to the sound
boards. These are required for all installations. Then refer to the specific instruction sheets for the
type of installation you intend to make. Before proceeding with the installation read the balance of
the instructions carefully so you will be completely familiar with what is required and what sounds
you should hear. The sound boards also have appropriate silk screen labeling to further clarify the
functions of controls and connections.
The circuit boards should be mounted in appropriate locations. The main board is usually in the
locomotive tender along with the volume/treble/bass board so that the volume and other controls
are accessible either through the frame or via a hatch or a hole in the tender body shell. Be
certain that the components on the circuit board do not come in contact with any metal objects as
such contact can destroy the sound system. The tender speaker, which contains all sounds,
should be mounted as per available space bearing in mind that sound reproduction is enhanced
when a speaker is properly enclosed and baffled (the tender will serve as a proper baffle if near
or fully enclosed).
If a DC locomotive is not moving, there is no track power, therefore to have sound it is necessary
to have a separate power supply for the sound system. For in locomotive use, this separate
supply is a battery. We suggest the use of 6 AA batteries in series (7.2 volts for rechargeable's or
9 volts for standard batteries) to maximize volume potential and battery life. Rechargeable
batteries can also be used. When connecting the battery (DC) power leads be absolutely certain
that wires connect to the proper DC input leads. IF THESE CONNECTIONS ARE REVERSED
YOU WILL DAMAGE THE SOUND SYSTEM.
 This is not covered under any warranty and will be
obvious to us when returned for repair (tracks are burned through on the circuit board and parts
