Overview
Congratulations on the purchase of your Tsunami2 or Econami Digital Sound Decoder! Properly installed, this decoder will provide high-quality sound, realistic lighting effects, and superior motor control. This installation guide will give you step-by-step instructions to successfully install the following Tsunami2 and Econami formats for steam, diesel, or electric locomotives:
Though each decoder is tested thoroughly before shipping, we cannot control the correctness or quality of a given installation. It is imperative that you follow the directions, and never remove the protective heat-shrink from the decoder; there are no adjustments that can be made to the hardware and this will void your warranty.
The difficulty of an installation depends principally on the modeler, and may be more or less challenging according to any given circumstance. However, an installer should generally have basic modeling skills, be comfortable disassembling a model, and be able to identify wires, such as power pickups and motor leads.
Note: In the event that you damage the decoder during installation, our warranty policy is outlined in the User’s Guide and on our website. It includes information about returning the decoder to SoundTraxx for repair or replacement.
Further documentation regarding steam, diesel, or electric versions of your decoder:
If you’re new to DCC and sound, refer to the Quick Start Guides for default operation and
programming highlights.
Refer to the User’s Guides for in-depth instructions regarding operating and programming
your digital sound decoder.
Refer to the Technical References for details regarding each CV included in your Digital
Sound Decoder.
Refer to the Sound Selection References for a quick guide of CV values to adjust sound
effects in each version.
Refer to the SoundTraxx Guide to Successful Soldering for soldering tips and
recommendations.

Pre-Installation Considerations
Carefully read the instructions that are printed on the decoder’s packaging. Then, finish reading this installation guide. While installing the decoder, keep these precautions in mind:
Handle the decoder carefully in a
static-free environment. To discharge static electricity before handling the decoder, touch a water pipe or another grounded metal surface.
Never remove the decoder’s protective
shrink tubing; this voids your warranty.
Never make connections to the decoder
while it is receiving power.
Make sure all electrical connections are
insulated. Avoid using electrical tape; it tends to unwrap over time. We recommend using heat-shrink tubing instead.
Never allow the decoder leads to come
in contact with any DCC track wiring not specifically designed for that purpose.
Never allow speaker or motor outputs to
be shorted together.
Do not exceed the output ratings for
which the decoder is designed.
Do not choose a locomotive with a stall
current exceeding the decoder’s rating; always test the stall current of your locomotive before installing the decoder.
If possible, mount the decoder in an
area with some airflow to provide ventilation for the decoder.
Mount the decoder away from other
heat sources (such as the motor or lamps) to avoid overheating.
Always use a proper speaker enclosure
(baffle) and select the largest speaker
possible. Choose an appropriately rated speaker. Take your time and have fun!
Testing the Decoder Prior to Installation
In rare cases, damage received during shipping or improper handling can cause a decoder to fail prematurely. We recommend that you test all Digital Sound Decoders and accessories within the item’s warranty period prior to beginning the installation. Proper bench testing of decoders can save countless hours of headache and frustration if problems are discovered after the installation process has begun
Testing the decoder on your workbench can be accomplished by connecting the wires/pads from the DSD to a surplus motor, 8 ohm speaker and 12 volt lamps. Refer to the appropriate wiring diagram for your decoder when making these connections. Also ensure that the wire connections are mechanically sound and well insulated to prevent damage to the decoder or accessories during testing.
When the appropriate connections have been made, test the motor by running it in both forward and reverse directions. Test each lighting output by turning on the corresponding function key. Lastly, check the audio output of the DSD by blowing the horn or whistle, ringing the bell and listening for changes in prime mover notch, exhaust chuff or traction motor whine.
If you should discover any issues during this test, please contact our Customer Support department for assistance.
Note: Neither Tsunami2 nor Econami require a programming track booster.

Miniature Speakers, Baffles, and Gaskets:
We have a variety of miniature speakers, baffles, and gasket kits for use with our digital sound decoders; choose the largest speaker the installation will allow.
Wiring Aids
Micro-connectors can be used to facilitate easy separation of components. NMRA-Compatible Connectors are used for converting universal-style decoders to a “plug-and-play” format. DBX-9000 Wiring Kit facilitates easy separation of the locomotive and tender. Super-flexible wire is ideal for working in tight spaces.
DCC Accessories
The CurrentKeeper helps maintain decoder performance during momentary power losses. Microbulbs and LEDs let you take advantage of our Hyperlight lighting effects.
Tools and Materials You Will Need
In addition to the common hand tools found on most modeler’s workbenches, you should have the following at your disposal:
Low-wattage soldering iron Rosin-core solder and electronics
safe flux Hobby knife Miniature screwdriver set Diagonal wire cutters
We have a variety of accessories to aid your installation. For more information about our full line of installation accessories, visit www.soundtraxx.com/access/index.php.

Step 1. Test the Motor Stall Current
Test the locomotive’s stall current to ensure that it is compatible with the decoder that you have chosen:
1. Place the locomotive on a section of track powered by a conventional DC powerpack set to the same track voltage as your command station (typically 12-14 volts).
2. Referring to Figure 1, connect a DC ammeter in series with one of the track feeders. If your powerpack has built-in meters, you may use them for this purpose.

3. Immobilize the locomotive by holding it to the track, and turn on the powerpack.
4. Firmly press down on the locomotive or hold the motor’s flywheel to stop it from spinning.
5. Ensure the powerpack voltage remains the same to receive an accurate measurement.
6. Measure the current the locomotive is drawing while the motor is stalled; this is the stall
current.
7. Ensure the motor stall current is less than the decoder’s rated capacity.

Step 2. Plan the Installation
The sound quality you will receive from your Digital Sound Decoder depends upon your speaker selection, the way you install the speaker, and the location of the decoder within the model. Consider the following as you plan your sound installation:
Provide ventilation for the decoder if
possible.
Mount the decoder away from other
heat sources (such as the motor or lamps) to reduce the chance of overheating.
Always provide a proper enclosure
(baffle) for the speaker. Lack of a speaker baffle will cause poor sound quality.
Speaker Considerations
Select the largest speaker that your model permits to achieve higher volume and better quality low-frequency response for a more realistic sounds. We offer a range of speakers that you can use with your model.
Note: Be sure that your speaker is rated to match the audio amplifier of your decoder; failure to do so could cause damage to your speaker. Check the packaging and our website for ratings for each decoder format.
Note: If a single large speaker isn’t an option, you may be able to use two or three smaller speakers to improve the frequency response. For details, refer to “Wiring
Multiple Speakers” within Step 6. Install and Wire the Decoder (Pg. 13).
Speaker Enclosures
A speaker enclosure (baffle) should be used to allow air pressure to build up and amplify sound.
The enclosure should fit the speaker. The pressure building within an enclosure that is too small for the speaker will compromise certain frequencies and muffle the sound response. As a guideline, enclosures for speakers measuring less than 3” in diameter should be built using the cubic relationship between height, length and width. For example, a 1” speaker should be paired with a 1” x 1” x 1” enclosure.
Note: Employing a proper speaker enclosure cannot be emphasized enough; the absence of an effective enclosure is almost always the cause of poor sound quality.
Speaker enclosures should also be:
Fixed with stiff walls to prevent
vibrations and buzzing
Installed flush with the speaker
dimensions to create an airtight space for the speaker cone to build pressure and produce a strong sound response
We offer various snap-together baffle kits like the one shown below.
