Soundtraxx Tsunami2 Bachmann Sound Decoders TSU-BH1
Tsunami2 Sound Decoders – TSU-BH1 from SoundTraxx are premium board-replacement digital sound decoders designed specifically to upgrade Bachmann Sound Value HO scale diesel locomotives. Built on the advanced Tsunami2 Digital Sound Decoder platform, the TSU-BH1 delivers dramatically improved diesel sound quality, refined motor control, and expanded lighting and function capability.
Bachmann Sound Value Diesel Board Replacement
The TSU-BH1 is engineered as a direct replacement for the factory Sound Value decoder used in many Bachmann diesel models. Installation is straightforward for users familiar with board-replacement installs—simply remove the original Sound Value board and install the TSU-BH1 to unlock the full Tsunami2 feature set.
This decoder is designed to replace the factory board in the following Bachmann Sound Value diesel models:
- FA-2, FB-2
- S-4
- E7-A, F-7
- GP7, GP30, GP38-2, GP40
- RS-3
- SD40-2, SD70ACe
- ES44AC
Advanced Tsunami2 Diesel Sound Profiles
The TSU-BH1 is available with multiple diesel sound profiles, including EMD, GE, and ALCO. Tsunami2 sound technology provides rich, dynamic audio with realistic prime mover behavior, throttle-responsive sound transitions, and a wide range of auxiliary effects that bring diesel locomotives to life.
8 LED-Friendly Function Outputs & HyperLight Effects
This decoder includes eight LED-friendly function outputs, allowing LEDs to be connected directly without external resistors. Lighting effects are fully remappable and provide access to more than 20 HyperLight lighting effects, supporting headlights, ditch lights, number boards, beacons, cab lighting, and other prototype-specific effects.
Refined Motor Control & Reliable Operation
Tsunami2 TSU-BH1 decoders deliver smooth starts, excellent low-speed performance, and consistent motor response. The decoder includes a dedicated connector for adding a CurrentKeeper-style energy storage device to help maintain sound and motor operation over dirty track, turnouts, and brief power interruptions.
Speaker & Installation Accessories
A compatible speaker is required for sound operation and is sold separately. For best results, pair the TSU-BH1 with a properly sized SoundTraxx speaker and use speaker baffles and gaskets to improve enclosure performance. Additional installation accessories and wiring aids are available to assist with clean board-replacement installs.
Compare Other Tsunami2 Decoder Formats
If your locomotive does not use a Bachmann Sound Value diesel board, you may want to explore other Tsunami2 formats such as TSU-1100, TSU-2200, socket-based options like TSU-21PNEM8 or TSU-N18, or high-output solutions such as Big Steam.
