eMOTION S Sound Decoder
Universally applicable sound decoder for analog and digital operation; equipped with a SUSI interface and a 3 Watt output stage.

eMOTION S The tiny sound decoder.
The eMOTION S sound decoder has the same sound features as the XLS sound decoder.

All sound features are available at the lowest voltages possible. A stabilized analog operation is guaranteed at 5Volts.

The eMOTION S supports the full NMRA protocol. The eMOTION S features an automatic detection of LGB® MTS signals which makes this sound decoder ideal for all generations of the LGB® MTS system. The bus interface may be used with Massoth/LGB® OnBoard or SUSI protocol. Fits into all G-Scale locomotives like Bachmann, USA-Trains, Aristocraft, Accucraft, KISS

AUTHENTIC SOUND in digital quality

The eMOTION S sound decoder produces authentic locomotive sounds in digital high-level quality. Massoth uses only sound recordings of original locomotives adjusted to the sound decoder's technology. The eMOTION S may hold more than 2 minutes of sound. This enormous capacity is sufficient for a variety of additional high-quality sounds. The sound decoder features a 3-Watt high-performance output stage. The volumes of all 16 sounds may be adjusted separately.
Massoth utilizes top-of-the-shelve technology paired with state-of-the-art processing ensuring reprogramming via the programming track. This guarantees that all decoders may be updated at any given time as well as for all new decoder generations to come.
Note: A sound upgrade or firmware update may only be done with our PC-Module (8175001)!

Summary of features:

  • Digital sound module16 kHz sound processing Capacity of sound memory + 2 minutes Analog and digital operation, SUSI interface, LGB® OnBoard Analog operation starting with 5 Volts3 Watts output User-friendly terminals to connect
       external volume control and
       pulse generator Additional terminals for
       power buffer
       2 function outputs
       2 contact inputs Wide range of sounds available
  • Updatable via PC-module
  • Measurements: 35 x 20 x 12 mm (plus 2x 5mm extensions which may be cut off)

Special features for Mallet, Rack and Dual Power Locos:

  • Manual selection/activation using F Function Key control: Function key for steam rack rail loco and dual power locos (since version 2.5) use CV 170 to define function key which activates the rack noise on a steam rack rail engine or switches the sound from electric to Diesel on a dual power loco.
  • Automatic Synchronization using 2 separate wheel sensor inputs: The S Decoder, like the XLS, has 2 separate wheel sensor inputs for synchronizing the the chuffs to wheel rotation of locos with two pairs of steam pistons like on Mallets and Rack Locos. This provides automatic synchronization so a rack loco cadence changes with the speed of the rack steam pistons and Mallet double motor blocks.


The eMOTION S comes with an attached power cable and the SUSI interface cable.
In case your locomotive does not provide a loudspeaker you may choose one from our wide range of loudspeakers.
Here you can find the list of loudspeakers of each loco.

Any Loco sounds from the Massoth sound library can be installed with the Massoth PC-Module.
