SoundTraxx 886007 | Tsunami2 TSU-N18 Electric Digital Sound Decoder | Multi Scale

The SoundTraxx 886007 is a TSU-N18 Tsunami2 digital sound decoder with the Electric 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 the Next18 decoder for N and small HO models, rated 1A and suited to N and small HO models with a Next18 socket. Dynamic Digital Exhaust reads the load on the motor and notches the traction motor up and down on its own, so the locomotive sounds like it is working for its train.

• AC traction motor sound with pantograph up/down (interlocked so the loco will not move with the pantograph down), trolley bell, stop-request bell, pneumatic doors and cab chatter
• Dynamic Digital Exhaust (DDE) matches traction motor sound to the load on the motor automatically
• Independent and train brakes with adjustable rates
• 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

Shop the full SoundTraxx range, compare every DCC decoder we stock, or see the other Electric sound profile 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 25 x 9.5 x 4.1mm and connects by next18 (n18) socket. 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.

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.
