  • SoundTraxx 885606 BLU-2200 Blunami GE Bluetooth DCC sound decoder for model trains SoundTraxx 885606 BLU-2200 Blunami GE Bluetooth DCC sound decoder for model trains - package

    SoundTraxx SoundTraxx 885606 | BLU-2200 Blunami GE Diesel Sound Decoder | Multi Scale

    1 In Stock In Store

    The SoundTraxx 885606 is a BLU-2200 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 universal-style Blunami that fits most HO diesels, suited to HO and small S scale. 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 6 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 885606 Model: BLU-2200 Blunami Sound Set: GE Diesel Scale: HO and small S scale Decoder Size: 35 x 18 x 6mm Connection: NMRA 9-pin JST harness to hardwire Max. Motor Stall Current: 2A Function Outputs: 6 Audio Amplifier: 2 Watt, 8-Ohm Load DCC Track Voltage: 7V – 22V Sound Channels: 16 polyphonic Processor: 32-bit, 28 functions Control Modes: DC, DCC and Bluetooth wireless Shop the full SoundTraxx range, compare every DCC decoder we stock, or see the other GE sound profile decoders. A speaker is not included — browse DCC speakers rated 2 watt or better, and find install parts in DCC wiring. Add a SoundTraxx 810140 CurrentKeeper to keep sound alive over dirty track and turnouts. FAQ Do I need a DCC system to use this?No. That is the point of Blunami. It runs on a plain DC power pack with no command station at all — you control it from the free Blunami app over Bluetooth. It is also a fully NMRA-compliant DCC decoder if you already run DCC. Does the app work on Android?Yes. The free Blunami app is published for both iOS and Android. (Some older listings and dealer pages still say iOS only — that is out of date.) Is a speaker included?No. Pair it with an 8-ohm speaker rated 2 watt or better that fits your shell. Which prime movers do I get?All 8 listed above, selectable in the app or via CV 123. You are not locked to one engine sound — pick whichever matches your prototype. Will it fit my locomotive?This one measures 35 x 18 x 6mm and connects by nmra 9-pin jst harness to hardwire. Check the space in your shell against that footprint before ordering — other Blunami versions use different connectors and sizes.
