Soundtraxx Econami

Now the biggest name is sound is also biggest name in value! Econami is a full-featured line of digital sound decoders designed with value in mind.

Now available in five formats to suit a variety of steam, diesel and electric 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 21-pin ECO-21P mates nicely to any model with the NMRA-supported 21-pin socket.

The new ECO-200 offer high amp motor circuit suitable for use in older HO models as well as many S and O gauge models. The new ECO-PNP presents all of the great features of the Econami line of decoders in the ever-popular HO Scale drop-in style board used in many Athearn, Atlas, and similar models.

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. And finally, for the first time ever, each format is available in an electric version that includes a trolley bell, air whistles, generator, pantograph, pneumatic doors, and more!

The Econami Digital Sound Decoders are not only a fully capable line of decoders, but in many ways surpass our recently discontinued Tsunami sound decoders. They can do everything the Tsunami could do, minus only two features - reverb and Fireman Fred.

Econami has 16-bit sound and uses some new recordings in addition to some re-mastered classics. With some impressive volume and new features such as Hyperdrive2, which provides much improved slow speed control, this product is by no means a little brother to Tsunami!

The line is also packed with new Hyperlight effects and Flex-Map Function Mapping technology, which allows 28-function support - any button can control any sound, light or logic effect!

Use this handy portable tool to keep your servos centered while you mount them under the layout.

The tool consists of a battery box connected to a small circuit board that continuously puts out a centering signal for the servo (1.5 ms pulse).

Keeping your servos properly centered while mounting is the key to making the servos work best.

The battery box has an on/off switch to save your batteries when not in use.

Everyone using servos for turnouts needs one of these.

Requires 3 AA batteries.
