The LokSound 5 Fx is a special feature of the LokSound family: it has no output and is specially designed for use in control cars or drive heads, which require a sound but do not have a model drive themselves. By omitting the engine part, it can still offer all the sound features of the other LokSound 5 members on a size of only 21.5mm x 15.5mm.

LokSound 5 Fx decoders are offered with an 8-pole interface according to NEM652 or a 21MTC cutting point and always come with an 11 x 15 mm 'sugar cube' loudspeaker and sound capsule kit.


Like all family members, the LokSound 5 Fx is a true multi-protocol decoder. It masters the DCC data format as well as Motorola, Selectrix and M4. In DCC format, 14 to 128 driving steps are as self-evident as 2- and 4-digit addresses and up to 32 functions. With the help of RailComPlus technology, the decoders register fully automatically at a suitable digital center.

It masters all DCC programming modes and can be both driven and programmed with compatible digital centers: Thanks to RailCom, it is possible to read out the CV values on the main track with suitable control panels. Auxiliary registers exist for control panels that can only program the CVs from 1-255.

Motorola users benefit from up to 28 driving steps at 255 addresses. Three additional Motorola addresses enable the triggering of 16 functions. A built-in programming mode also makes reprogramming possible with the venerable Control Unit 6021.The M4 protocol allows automatic login to mfx-compatible control panels.

The LokSound 5 Fx Decoder detects the Märklin brake distances as well as ZIMO HLU brake commands or the Lenz ABC system. Also the ‘brakes’ with DCC brake blocks or with DC voltageis possible. It also stops with a Selectrix brake diode. An ABC commuter train system allows automatic commuting between two stations.

The LokSound 5 decoder can be used on analog DC and AC webs.

The decoder switches ‘on-the-fly’ fully automatically between operating modes. Most of the time, nothing needs to be adjusted.


The LokSound 5 Fx decoder can play up to 12 channels simultaneously. Each channel can be resolved with up to 16 bits / 31250 kHz and offers hi-fi quality on your system. There is virtually no difference to the original audible anymore. A Class-D audio output stage with up to 3W output controls the speakers, which may have between 4 ohms and 32 ohms impedance. A 128 Mbit sound memory provides enough capacity.

All individual noises can be adjusted individually in the volume. The super-flexible sound gine without a rigid schedule allows the exemplary simulation of all conceivable rail vehicles.


There are also some lights to turn on in the control car or drive head. That's why we have equipped the LokSound 5 Fx with 6 reinforced function outputs. In the version with 21MTC interface, 6 outputs are added for controlling servos or logic level outputs. All important lighting functions are available. The brightness of each output can be set separately.


Although the LokSound 5 Fx itself does not have an engine output, it still ‘simulates’ one. This is used for synchronization with the motor car, where ideally a ‘full-fledged’ LokSound 5 decoder performs its service. In the train bandage, this ensures that the brake squeak takes place at the same time or that the lamps also switch the direction of travel at the same time.

Operational reliability

A PowerPack can be connected to the LokSound 5 micro DCC Direct Kato USA on request to bridge dirty rail sections.


Of course, the outputs are protected against overload. We want you to enjoy your decoder for as long as possible

Designed with future developments in mind

The LokSound 5 is update capable and can get its new firmware with the aid of an ESU LokProgrammer to do so.
