The SoundTraxx 885001 is a TSU-1100 Tsunami2 digital sound decoder with the EMD sound set. Tsunami2 combines a 16-bit sound system, Hyperdrive2 motor control, Hyperlight lighting effects and a full NMRA-compliant DCC decoder on one board, driven by a 32-bit processor with 16 polyphonic sound channels.
This version is a compact universal-style decoder for tight installs, rated 1A and suited to small models with minimal space. Dynamic Digital Exhaust reads the load on the motor and notches the engine up and down on its own, so the locomotive sounds like it is working for its train.

Shop the full SoundTraxx range, compare every DCC decoder we stock, or see the other EMD / EMD-2 Diesel decoders. A speaker is not included — browse DCC speakers rated 1 watt or better, and find install parts in DCC wiring. Add a SoundTraxx 810140 CurrentKeeper to keep sound alive over dirty track and turnouts.
Will this fit my locomotive?
It measures 27 x 10.5 x 5mm and connects by universal-style hardwire. Check that against the space in your shell before ordering — other Tsunami2 versions use different connectors and sizes.
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 via CV 123. You are not locked to one engine sound — pick whichever matches your prototype.
EMD or EMD-2 — which do I want?
This is the EMD set: the common 567, 645 and 710 prime movers. The separate EMD-2 set carries a second group of less-common variants called out by cylinder count. Match the list above to your prototype.
Does it run on DC?
Yes. Tsunami2 runs on a standard DC power pack as well as DCC, though sound and lighting options are limited on DC. Full function control needs a DCC system.
