The Digitrax SDXN147A0 puts motor control, lighting and SoundFX into one N scale board decoder, and it ships with the oval speaker already matched to it. It is a drop-in for many Atlas N locomotives, which means no harness to route and no hunting for a speaker that fits - the hardest part of an N scale sound install is already solved.

Will it fit my N scale locomotive?
It is designed as a drop-in for many Atlas N models. Board decoders are shape-specific, so pull the shell and compare the factory board footprint and light positions before ordering. If it does not match, a wired N decoder is the fallback.
Do I need to buy a speaker separately?
No. The matched 8 ohm oval speaker is in the box. You will still get noticeably better sound if you fit it against a baffle or a sealed pocket in the shell rather than leaving it loose.
Can I change the sound scheme?
Yes. SoundFX schemes and volumes are set through CVs, so you can adjust horn, bell and prime mover to suit the prototype you are modelling.
Do I need a Digitrax command station?
Not for running - it works on any NMRA DCC system. Loading new sound files does require a Digitrax programmer.
