for DC and DCC Operation
PLEASE READ FIRST
When carefully installed, this module will provide all the pleasures of high quality, digital onboard sound and the benefits of today’s DCC (Digital Command Control) technology. Please
note that while each module is tested thoroughly before it is shipped, Bachmann cannot control the correctness of the installation.
It is imperative that you read and follow the
information and steps below for a successful installation.
IMPORTANT FOR A SUCCESSFUL INSTALLATION
Before you install your sound module, there are some simple precautions you should take:
The electronics should be handled carefully in a static-free environment. To discharge static electricity,
touch a grounded water pipe or bare sheet metal surface before handling the module.
•
Work in a clean, well-lit area on a non-conductive surface. Stray metal scraps and dirt can get onto the circuitry and cause shorts.
• NEVER INSTALL THE MODULE WHILE IT IS POWERED.
•
Do not exceed the track output ratings for which the module is designed.
•
Do not install the module into a model that it was not designed for.

These instruction assume that you have some understanding of, or experience with DCC. It covers the differences you may need to know between this decoder and any you may have
previously used.
Your Bachmann Sound Decoder is both a DCC Sound Decoder and a DC Sound System. The sound decoder performs numerous functions on both Analog (DC) and Digital (DCC or Digital
Command Control). The operation of some of these functions will be different depending on which you are using:
Motor control
– the decoder controls the motor in both DC and DCC, enabling proper coordination of the locomotive’s movement with other operating features and sound effects.
Sound
– Customer-installed speaker required. The authentic sounds of your favorite characters are digitally reproduced through the powerful 3-watt audio amplifier. All sounds are
polyphonic; one sound will never interrupt another.
Lights
– Headlights and/or backup lights are NOT factory installed - however, should you wish to add LEDs, the sound decoder has the ability to turn them on or off in DCC mode using F0
(or F10 on the Bachmann E-Z Command
®
DCC system).
Troubleshooting Checklist
1. If there is no sound, be sure the volume control knob has not been turned all the
way off.
2. If operating in DCC mode, follow the “Starting Over” instructions to reset the
locomotive to factory default settings.
Adjusting the Master Volume in DC
If your locomotive has a volume control potentiometer, turn the knob clockwise to turn on the
audio portion of the sound decoder. This will not affect the operation of the motor, but allows
you to increase or decrease the overall volume of all the sound effects simultaneously. Turn
the knob all the way counter-clockwise to turn the audio off.
Use of the “Polarity” Switch
Due to varying standards, if you are running in analog mode with a DC power pack, you may
set the locomotive’s default direction of travel with the “polarity” switch under the model if
your locomotive is equipped with a polarity switch. Set to “Large Scale” or “NMRA” according
to your preference. When running in DCC, changing this switch has no effect.
is stopped. When operating in analog mode, be careful not to exceed the decoder’s input
voltage rating of 26 Volts. When your track voltage exceeds 28 Volts, the decoder will
automatically shut off the sound and motor: back down on the throttle immediately.
Power Supply
Important: Your sound decoder will work best in analog mode when using a high quality,
electronically regulated power pack, preferably one that supplies smooth, filtered DC power.
Older rheostat style power packs and pulse power packs will result in erratic and unreliable
operation and should NOT be used with this sound decoder.
Operating the Model
Once the throttle has achieved sufficient voltage, if the throttle is set to move the locomotive
forward, two blasts of the whistle (except Toby) will sound as the throttle is increased.
Increasing the throttle further will set the locomotive in motion, increasing speed as the
throttle is increased. The exhaust chuff is synchronized to the speed of the locomotive.
Once the locomotive has reached and maintained a constant speed, the whistle will sound
approximately every 20 seconds.
If the throttle is decreased slowly to stop, you will
also hear a steam release effect just before stopping.
