The SoundTraxx 885610 is a BLU-21PNEM8 Blunami digital sound decoder with the GE sound set. Blunami is a Tsunami2 with a Bluetooth radio added, so it runs three ways: as a normal DCC decoder on any NMRA-compliant system, on plain DC, or in wireless mode straight from your phone or tablet. Wireless mode needs no command station and no programming track — an old DC power pack and the free Blunami app are enough, and CVs can be read and changed over Bluetooth while the locomotive is running. The app is free for iOS and Android. This version is the 21-pin MTC plug-in Blunami, suited to HO scale and larger. Features 8 GE prime movers: GE FDL-12, GE FDL-16, GE 7FDL-16, GE Dual FDL-16, GE GEVO G12, GE 44-Ton Center Cab Dual Caterpillar, GE Cummins Switcher, GEVO G12 Tier 4 Over 40 air horns and 13 bells, plus air compressors, couplers and dynamos Bluetooth control from the free Blunami app (iOS and Android) — over 300 settings without editing a single CV by hand Dynamic Digital Exhaust (DDE) automatically matches exhaust volume and RPM to the load on the motor, and the app calibrates it for you Three braking types: independent, train and dynamic braking Hyperdrive2 motor control for smooth, creep-speed switching Over 20 Hyperlight lighting effects across 8 function outputs 16 polyphonic sound channels on a 32-bit processor, with a 7-band equalizer and adjustable reverb CurrentKeeper ready — works with the SoundTraxx 810140 CurrentKeeper More Information Item Number: SoundTraxx 885610 Model: BLU-21PNEM8 Blunami Sound Set: GE Diesel Scale: HO scale and larger Decoder Size: 30.5 x 15.5 x 6.5mm Connection: NEM660 21MTC integral connector Max.
