OVERVIEW: This device is an electronic, self contained, sound system for installation in model

diesel locomotives that are designed to operate with conventional DC track power, digital (DCC) or other types of command control systems including radio with either track or battery power, also as a stationary sound unit. Because of its dimensions (2.7" x 0.9" x approx. 0.5" high) the sound system may be limited to installations in some powered units making the need for use of a "dummy" unit or a trailing car. An alternative installation under the layout is also possible including the use of our TRAK-DT devices to switch the sound through multiple speakers so as to follow the movement of the train. A drawing for this application is in our Model Railroaders Wiring Guide.

An on/off switch (not included) must be used to power the sound unit on and off in some applications. The audio amplifier can produce one watt of power which is in excess of wh at most small speakers can handle. The speaker impedance must be 8 ohms or higher. Sound volume is adjustable. Refer to our catalog for available speakers. If space per mits, the optio nal ova l speake rs (Items 662, 664, 665), which are higher wattage speakers, are the best choice.

Sounds produced include user controlled horn, bell force notch 8 and main sou nds on/off (leaves the main sounds off while allowing for horn and bell operation). Non-user controllable sounds include periodic air system pressure release, brake release and diesel prime mover sound automatically adjusted to speed and load conditions.

This sound system, when used with conventional DC track power, requires the use of our LocoMatic™ Controller (Item 755) to operate the horn, be ll, force notch 8, and main sounds o n/off. DCC and other command control operators can use remote functions on their systems to activate the same functions. For stationary installations, these functions can be accessed by switches. Radio control with fixed track power or on board batteries would be similar to DCC installations and large gauge (where you ride the locomotive) would be similar to a stationary installation.

INSTALLATION INSTRUCTIONS:

speaker, five 2-pin connectors with wires and two 3-pin connectors with wires. A CHOKE (item 70 or 703 depending on motor power requirements), not include d, is required for DC track power installations.

Refer to the drawing on page 2 to familiarize yourself with the connectors and controls on the sound board. Then refer to the specific instruction sheets for the type of in stallation you intend to make. Before proceeding with the installation read the bala nce of the instructions carefully so you will be completely familiar with what is required and what sounds you should hear.

The circuit board should be mounted so that at min imum, the volume control is accessible either through the frame or via a hatch or a hole in the locomotive 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 speaker should be mounted as per available space bearing in mind that sound reproduction is enhanced when a speaker is properly enclosed and baffled.

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 sup ply is a battery. We suggest the use of one 9 volt or 6 AA or 6 AAA batteries in series to maximize volume potential and battery life. Rechargeable batteries can be used. When connecting the battery (DC) power leads be absolutely certain that wires connect to the proper DC input leads.

If any connections are not done properly, especially the power connections, you will damage the sound system. This type of damage is not covered under any warranty. The sound system is

SOUND INFORMATION: PRIME MOVER (DIESEL):

sounds range from idle to full RPM with eight notches. With no power to the track / motor the sound system will produce engine idle sounds. As a throttle is advanced to put the locomotive in motion, a brake release will sound (see below) and the diesel will initially accelerate to notch #4, and then seek the correct notch setting for locomotive speed. There will be a distinct volume increase during acceleration. W ith our LocoMatic™ Controller (#755), activating the ALT and F3 buttons simultaneously (and then releasing) will direct the sound system to accelerate to full RPM regardless of track / motor voltage. Activating both buttons again will release the sound system to return to the correct notch setting. This feature allows the simulation of a heavy load with very slow locomotive speed or "pumping air" in a standing train. This full RPM feature is available to other users either by a switch or with a remote fun ction. The prime mover, air pops, and brake release sounds can be turned off without turning off the sound system. This way you can still activate the Horn and Bell. With our LocoMatic™ Contr oller, use ALT F4 as a press on, press off. For other receivers or stationary, a function or single pole switch will suffice.

AIR RELEASE (POPS): Air is pumped continuously in a diesel locomotive to mainta in pressure in

the brake system and for other purposes. Periodically the pressure will increase and the excess will be released through the safety valve. These AIR RELEASE sound (pops) are generated at random intervals during idle and at all notch settings.

BRAKE RELEASE:

sound is produced when the throttle is advanced from the idle position. This brake release should always precede locomotive movement but will only occur if the diesel sound is actually at idle. This BRAKE RELEASE has been factory preset but is user a djustable. For DC operators, this requires approximatly 1.5 to 2 volts of input voltage to sense a running mode.

HORN: sound is controlled by the HORN button on the LocoMatic™ Controller, by a momentary

push button or by remote function, dependent upon the type of installation. The HORN 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, by a toggle switch or

by remote function, dependent upon the type of installation. The sound system includes a routine which ignores intermittent BELL requests, resulting in a delay when activating or deactivating the BELL. When BELL sound is requested the sound system will first adjust the diesel sound to the RPM required for simultaneous play. When deactivating, the BELL will stop at the end of a ring and the diesel sound will return to the correct notch setting. The BELL CANNOT BE ACTIVATED if the diesel sound is above notch #5. 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. Toggle switch or remote function control does not require the PUSH ON - PUSH OFF sequence.

SPEAKER MOUNTING:

The speaker generally should be mounted so that the so und can a ctually "get out" of the locomotive. A hole in the floor or fuel tank is acceptable but open grills or a doorway may be a better choice as the sound can exit u pward rather than down toward the track. In some cases, particularly with plastic body shells, just mounting the speaker against the shell will be adequate as the vibrations of the shell can enhance the sound. Enclosing the speaker in a chamber will also enhance sound reproduction. A very simple enclosure can be made with a tube. The longer the tube the better the speaker will reproduce low frequency soun d which is inherent in diesel prime movers. It is usually best to seal the end of the tube, so there are no air passages to the rear of the speaker, thus creating a sound chamber. By carefully sealing all openings it may be possible to use the entire 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 b ottles 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. 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 experim entation is definitely in order f or your installation so as t o gain the maximum benefit of the superb sound quality available in this sound system.

GENERAL OPERATING INFORMATION: VOLUME ADJUSTMENT :

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 lo uder 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.

This diagram allows for the use of rechargeable batteries. When track voltage

exceeds battery voltage, the sound system will operate from track voltage and the battery will start to charge (when in the forward direction). If you need to charge the battery fully without the sound system on, place the locomotive on the track (with the motor not powered if present) and leave full track voltage on for 14 hours. The batteries will charge whenever the locomotive track power is set for the forward condition regardless of the sound system being on or off. They will not charge when the polarity on the track is set in reverse. When running in reverse, the sound system will only operate from the battery. A bridge rectifier could be used instead of a single diode alleviating this potential problem.

ATTENTION

ALL FUNCTION CONNECTIONS are for OPEN COLLECTOR type FUNCTIONS such as those found on DIGITRAX, LENZ, NCE, and WANGRO receivers. Although there should not be any

problem with any other type, we have not verified it. The sound unit has been designed and operated with WANGRO, DIGITRAX, and LENZ systems to verify DCC operation and compatability.

ADDITIONAL NOTES:

If you feel that you need longer running time when an intermittent track power input occurs simply attach a larger filter capacitor across the DC power leads (J2). Observe proper polarity. The plus connects to pin 1 (red), minus to pin 2 (gray) - the polarity is very important since some capacitors when connected in reverse can actually blow up like a fire cracker! The larger the capacitor the longer operating time without track power. A capacitor of 470 mfd @ 25vDC should be sufficient, too large of a value will require a very large surge current when track power is applied. Some transmitters cannot take the large surge current on startup and will show an overload condition when powering up.

This is possible when both the receiver and sound system are operating

from a common supply. The common supply can be either fixed track voltage or fixed battery voltage. Since both the sound system and the

receiver are operating on the same supply, the common "—" power

DC power output.

This is the rectified power from the sound system. When operating on DC track power, since the polarity is unknown, the input power must be connected to J1 (AC) input power. If nothing else is connected to the RED lead, make sure it is properly insulated to prevent a short.

The "+" power is not intended to operate equipment, rather it is an input for the sound system. In this configuration however, it is possible to use this as an output providing the item connected does not draw very much power. A few 100 milliampere's max.

If DC power is required for other, higher current items, use a separate bridge rectifier to obtain the DC necessary.

In an Aristocraft locomotive ready-equipped for radio installation, wires have to be

connected from the sound card to the motor leads as shown. The receiver will be already

connected to the motor brushes by plugging the reciever board into the engine.

Connect to receiver motor lead power. Then connect the motor leads to pins 2 (black) and

3 (white) of J3. If using higher than 12 volts track power, connect the optional resistor as

shown for better notch control.

More than one power amplifier can be used. To do so connect the input wires (gray) in parrallel from the amplifier to the sound systems gray speaker wire or use one amplifier for each sound system.

Input voltage of 12 to 24 volts DC.

Connect to the same power that is powering the sound system.

If this is a DCC system, one of the sound

units needs to have J1 connected to the track power and no battery power or an on/off switch would be connected. Switch inputs s1 - s4 would be functions.

using dual systems with LocoMatic™ Controller

To strap off the Horn and Bell in a diesel unit, connect the SYNC white wire to the black wire. This will allow only the prime mover sounds to operate. Cut the white wire off or remove from the connector.

Refer to page 9 for using two sound units. The top sound unit would be

connected as shown on page 9 without switches S1 and S2. The lower sound unit, producing the prime mover sounds, would be connected as shown to the left with nothing connected to J4 or J5.

Track power inputs, as shown on page 3 and 4, will be the same except they

will go to both sound systems J3 connectors.

Battery connections will go to both units DC power input connector, J2.

If you do not care to use an amplifier, you must use two seperate spea kers. In

that case, each sound system will have their own speaker. The speaker connected to the lower sound unit would then produce the prime mover sounds with air and brake release sounds, and the other speaker, connected to the upper sound unit, will produce the Horn and Bell sounds.

With single sound systems, connect the gray wire from the speaker output to input "I". Connect the rest as shown.

If using two sound system as shown on page 9, connect the junction of the two sound systems

to the capacitor as shown on page 9, then merely add the potentiometer as shown. This will only work properly if the amplifier has an industry standard auxillary input.

matching transformers can be found in many audio shops. They are used for power amplifiers found in car systems.

Sometimes it is necessary to make a small

baffle inside an open shell. Again, make sure

all areas that encase the backside of the speaker are closed.

Using the fuel tank as a speaker baffle

is quite easy. In this case the speaker eminates sound into the body.

Sample Speaker Installations

For open body shells it is necessary to

make a speaker baffle instead of using the body for a baffle. In both cases, the backside of the speaker is closed off.

Mounting a speaker facing out from

inside of the body. You have to seal all edges of the speaker for a proper baffle.

Aristocraft SD45 or other

similar installations. This locomotive and

others do not have a proper speaker installation. It is necessary to make a baffle to mount the speaker with. The baffle prevents air from circulating from the front of the speaker to the rear of the speaker. Circulating air prevents the sound

from proper reproduction

and significantly reduces

the volume!

Mount the speaker and

seal all edges with either "hot melt" or silicone seal. Make sure that all edges

are properly made air

tight! In this engine, the sound is

projected through the fans.
