It is a full NMRA-compliant DCC decoder rated 1A, connecting by 21-pin dual-row bottom-entry nem connector.

How is Econami different from Tsunami2?
Both are 16-bit with Hyperdrive2 motor control, 28 functions and 20+ lighting effects. Econami has a smaller sound library (4 chuffs, 16 whistles and 6 bells against Tsunami2’s 10, 90 and 12), 12 sound channels instead of 16, and no reverb. If your prototype is covered by the list above, Econami saves you real money.

Is a speaker included?
No. Pair it with any 8-ohm speaker rated 2 watt or better that fits your shell.

Does it have Dynamic Digital Exhaust?
Yes. The Econami steam decoders include DDE, which notches the exhaust automatically with the load on the motor.

Will it fit my locomotive?
It measures 30.5 x 15.5mm and connects by 21-pin dual-row bottom-entry nem connector. Check that against the space in your shell before ordering.
