Digital Sound Decoders

Now the biggest name in sound is also the biggest name in value! Starting at $79.95 MSRP, Econami is a full-featured line of digital sound decoders designed with value in mind.

Available in five formats to suit a variety of steam and diesel locomotives, Econami provides high-quality, 16-bit sound, Hyperlight lighting effects, and Hyperdrive2 advanced motor control for enhanced realism. New features include Flex-Map technology, an easy-to-use method for assigning any function to any function key.

The Econami line includes our smallest sound decoder, the ECO-100, measuring just 27mm x 10.5mm x 5mm, as well as the ECO-400 4-amp version for models requiring a little more “beef.”

The 2-amp ECO-200 and the ECO-PNP decoders are our two new additions to the Econami line. The ECO-200 is a new universal-format Econami suited for a variety of scales, HO to S. The ECO-PNP will easily replace the manufacturer-installed light board for a variety of models and is well suited to large steam tenders. Rounding out the line, the 21-pin ECO-21PNEM mates nicely to any model with the NEM-supported 21-pin socket.

Steam and diesel versions include a selection of exhaust chuffs or prime movers, along with 16 whistles or airhorns to suit the most popular models. In addition, each decoder features multiple options for airpumps or compressors, bells, and couplers for even more customization.
