Description
The SoundTraxx 885613 Blunami BLU-PNP8 brings Bluetooth wireless control and the full Tsunami2 EMD diesel sound library to locomotives in a plug-and-play board format with 8 function outputs. Drop the board into a compatible locomotive in place of the factory board, pair with the free Blunami smartphone app, and you are running with sound — no command station, no soldering.
Because Blunami is also a complete NMRA-compliant DCC decoder, the same locomotive runs perfectly on any DCC layout. The EMD library includes the classic 567/645/710 prime movers plus a deep selection of air horns and bells, with Hyperdrive2 motor control for smooth switching-speed performance. Eight function outputs support ditch lights, beacons, Mars lights, and other lighting effects.
Compatibility
- Plug-and-play (PNP) board format for locomotives that accept standard motherboard-style replacement decoders
- Controls via the Blunami app (iOS/Android), any NMRA DCC system, or DC
- Best suited to EMD-powered diesels — GP, SD, and F-units
How to Use
- Swap the factory board for the Blunami PNP board
- Confirm speaker and lighting connections, then test on the bench
- Pair with the Blunami app to select prime mover, horn, and lighting effects
