MYLOCOSOUND
UNIVERSAL SOUND FOR LARGE SCALE, DC, STEAM LOCOMOTIVES
1.OVERVIEW
 Easy installation using screw terminals with no soldering.
 Uses a TV remote control to adjust the volume and sounds to match the prototype loco.
 Provides a chuff sound which matches the loco speed and load.
 Sixteen pre-selected whistles, each with adjustable tone to suit the loco.
 Selectable sounds include whistle, bell, safety valve, "All aboard", brake pump, injector, guard's whistle
and brake squeal.
For track powered DC or battery powered radio controlled railways
2. CONTENTS
The soundcard generates synthesised sound which is adjustable to reproduce the sounds of
most steam locos and railmotors. The terminal connections on the right are necessary for
the soundcard to generate a chuff which varies with the loco speed and load. The terminal
connections on the left trigger the various sounds where the locomotive controller has the
appropriate outputs available. The trigger terminals are labelled F1 to F7 and are referred
to by these labels in these instructions. For example, "Triggering F1" means to close a
contact between the F1 terminal and the Battery negative terminal.
Sounds can also be triggered by the infra-red TV remote control which comes with the
soundcard. Although it can be used when running in the garden, the remote control is
intended mainly for the adjustment and testing of sounds due to its short range.
The remote control communicates with the soundcard via two infra-red receivers. One is
located on the soundcard and the other is on a flying lead which allows it to be fixed to any external
surface of the loco.
Adjustments to the sounds can then be made without taking the loco apart to access the soundcard.

  • Page 2 3. SPEAKERS AND SOUND QUALITY The soundcard requires an 8 ohm loudspeaker which is not included. A 4 ohm speaker can also be used but you may cause the soundcard to overheat and temporarily shut down if the volume is very high and the soundcard is in a confined space.. Your choice of speaker is highly important because it determines the quality of the sound produced.
  • Page 3 4. INSTALLING THE SOUNDCARD IN A TRACK POWERED LOCOMOTIVE, DC OR DCC The soundcard is suitable for use on analogue DC track powered railways on which the following wiring diagram should be used: The wiring diagram below shows the connections for the DC jumper board in a Bachmann locomotive. When the motor voltage is below seven volts it is insufficient to power the soundcard.
  • Page 4 On analogue DC layouts which have pure DC controllers (as opposed to PWM controllers) you may need to give the throttle a bit of a tweak to start the sound. On those layouts, the sound will automatically turn off after one minute of inactivity and another tweak will turn it back on. With the more common PWM controllers and with DCC the sound will turn on automatically and stay on.

    However, in the interests of domestic harmony, in which stealing your partner’s TV remote is probably a bad idea, MyLocoSound supplies a suitable remote control and that is the BrightStar illustrated here. Please ensure that your remote control has batteries installed and follow the instructions which come with it to set the coding.
  • Page 7 Note that the buttons on the MyLocoSound remote control auto-repeat if held down. If you want a single event to occur, like turning on the safety valve, then press the safety valve and release it immediately. If you want to make a large change in volume or tone then you can hold the button down to avoid the need to press the button repeatedly.
  • Page 8 Button 1 – Whistle. This is used to select the style of whistle which suits your locomotive. Every one of these whistles has an adjustable pitch and volume. Each time you press the 1 button the number of beeps will increase to indicate that the whistle listed below has been selected. If you wish to hear that whistle, press the Mute button on the remote control to reactivate the sound then press the 1 button to start the whistle and then again to stop it.
  • Page 9 When you are satisfied then restore the other sounds. A customer, Rik Bennett, has made an excellent video of setting the chuff which can be seen by going to YouTube and searching for “MyLocoSound steam setting”. It can also be accessed through the steam page at www.mylocosound.com.
  • Page 10 Button 9 – The Operating Mode. There are three operating modes available: One beep – Indicates manual mode. In this mode all sounds are triggered according to the above settings. With battery radio control, the whistle will sound for as long as the function 1 button is pressed.

    11. OPERATING THE SOUNDCARD When the loco is running, the engine sounds should operate automatically, getting louder when accelerating and softer when slowing down or idle. Where your controller has function buttons then you can use them as follows to trigger terminals F1 to F6 as follows: ...
  • Page 12 THE SOUNDCARD MAKES A CLICKING NOISE OR SHUTS DOWN This most often occurs when the whistle is sounded. It is caused by the soundcard restarting because there is insufficient voltage in the track or battery to sustain the volume setting. Recharge the battery. WHEN INSTALLED IN A LOCO, THE SOUND STOPS INTERMITTENTLY AND I HAVE TO RESET THE CONTROLLER TO GET IT GOING AGAIN The soundcard maximum output is 1.5 amps.
