The SoundTraxx 885603 is a BLU-1100 Blunami digital sound decoder with the ALCO 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 most compact decoder in the Blunami line — small enough for N scale, suited to N, HO and small S scale.

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 (Some older listings and dealer pages still say iOS only — that is out of date.)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 1 watt or better that fits your shell.
Which prime movers do I get?All 9 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 31 x 10.5 x 5mm and connects by hardwire (single wires). Check the space in your shell against that footprint before ordering — other Blunami versions use different connectors and sizes.
