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!
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 thoroughly tested and inspected before packing to insure proper function. There is a minimum charge of $35.00 plus s/h for repair.
SOUND INFORMATION: Cooling Fans (Electric): sounds range from idle (silent - no fans operate when not running) to full fan rpm. With no power to the track / motor the sound system will produce no sounds. As a throttle is advanced to put the locomotive in motion, a brake release will sound (see below) and the electric fans will accelerate to full rpm. With our LocoMaticTM Controller (#755), activating the ALT and F3 buttons simultaneously (and then releasing) will direct the sound system to ramp the fans to full RPM regardless of track / motor voltage. Activating both buttons again will release the sound system to return to the correct fan setting. This feature allows the simulation of more cooling when sitting after a heavy load run or "pumping air" in a standing train. This full fan RPM feature is available to other users either by a switch or with a remote function. The cooling fans, 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 LocoMaticTM Controller, use ALT F4 as a push on, push off. For other receivers or stationary, a function or single pole switch will suffice. BRAKE RELEASE: sound is produced when the throttle is advanced from the idle position. This brake release should always precede locomotive movement. For DC operators, this requires approximatly 1.5 to 2 volts of input voltage to sense a running mode for the brake release to sound. HORN: sound is controlled by the HORN button on the LocoMaticTM 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 LocoMaticTM 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. With the LocoMaticTM 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.
OVERVIEW: This device is an electronic, self contained, sound system for installation in model electric 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 what 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 permits, the optional oval speakers (Items 662, 664, 665), which are higher wattage speakers, are the best choice. Sounds produced include user controlled horn, bell force cooling fans and main sounds on/off (leaves the main sounds off while allowing for horn and bell operation). Non-user controllable sounds brake release and electric cooling fans sound. These automatically operate. The cooling fans can be manually controlled. This sound system, when used with conventional DC track power, requires the use of our LocoMaticTM Controller (Item 755) to operate the horn, bell, force cooling fans, and main sounds on/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: The sound system consists of a printed circuit board, a 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 included, 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 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 circuit board should be mounted so that at minimum, 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 supply 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. 1
SPEAKER MOUNTING: The speaker generally should be mounted so that the sound can actually "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 upward 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 sound which is inherent in electric cooling fanss. 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 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. 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 for standard 12 volts to the track / motor. Rotate the control CCW for all other operators using higher motor voltages. This control will have no real effect in this system but must be set correctly for higher motor voltages.

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 "Â" are connect correctly! If not, you will either burn out the sound unit or the supply feeding it. This is not covered under warranty!
