Tsunami2 Sound Decoders TSU-1100
Tsunami2 Sound Decoders – TSU-1100 from SoundTraxx are hard-wire, universal-style digital sound decoders designed for modelers who need maximum installation flexibility in locomotives with limited internal space. As one of the smallest Tsunami2 sound decoders available, the TSU-1100 delivers premium sound, advanced motor control, and extensive function capability in a compact 1-amp format.
Hard-Wire Universal Decoder Format
The TSU-1100 is a true hard-wire decoder. Unlike board-replacement or socket-based decoders, it installs using individual wires that are soldered directly to the locomotive’s motor, track pickups, lighting, and speaker connections. This universal format makes the TSU-1100 ideal for custom installs, older models, brass locomotives, and projects where no factory decoder socket is present.
Advanced Tsunami2 Sound & Operating Features
Built on the Tsunami2 Digital Sound Decoder platform, the TSU-1100 delivers an immersive cab-experience with advanced features such as Reactive Dynamic Digital Exhaust, functioning locomotive and train brakes, injectors, power reverse, and firebox flicker effects. Sound behavior responds dynamically to throttle and load for realistic operation.
Extensive Selectable Sound Library
The TSU-1100 includes a large selection of selectable sound effects, allowing modelers to tailor the decoder to a wide range of prototypes. Available sounds include multiple exhaust chuffs, prime movers, bells, whistles, airhorns, couplers, dynamos, and other auxiliary effects—making this decoder suitable for steam, diesel, and electric applications depending on the selected sound profile.
Micro 1-Amp Design for Small Locomotives
With its compact size and 1-amp motor rating, the TSU-1100 is well suited for smaller locomotives and tight installations where space is at a premium. This makes it a popular choice for HO scale switchers, smaller road locomotives, narrow-gauge models, and custom projects that cannot accommodate larger decoders.
Energy Storage & Reliable Operation
The TSU-1100 supports the use of an optional onboard capacitor or can be wired to a CurrentKeeper-style energy storage device to help maintain sound and motor operation over dirty track, turnouts, and brief power interruptions.
Speaker, Wiring & Installation Accessories
A compatible speaker is required for sound operation and is sold separately. For best results, pair the TSU-1100 with a properly sized SoundTraxx speaker and use speaker baffles and gaskets to improve sound quality. Clean, reliable installs can be achieved using installation accessories, wiring aids, and decoder wire.
Compare Other Tsunami2 Decoder Formats
If your locomotive supports a board-replacement or socket-based install, you may also want to explore Tsunami2 options such as TSU-2200, Bachmann Sound Value replacements like TSU-BH1 or TSU-BH2, or plug-style formats such as TSU-21PNEM8 and TSU-N18.
Frequently Asked Questions (FAQ)
