LokSound 5 Fx DCC Blank Decoder & Speaker 21MTC NEM660

Details:

The ESU LokSound 5 Fx is a specialist function-only sound decoder designed for vehicles that do not require motor control, such as control cars, cab cars, coaches, multiple units, and auxiliary power cars. By omitting motor output entirely, it delivers full LokSound 5 audio performance and lighting control in a more compact and highly focused design.

Despite being a function-only decoder, the LokSound 5 Fx retains all the advanced sound technology found in the LokSound 5 family. It is capable of producing high-fidelity multi-channel audio with realistic prototypical sound behaviour, making it ideal for synchronised sound effects in non-powered rolling stock within a complete train consist.

The decoder is available with common interfaces such as 8-pin NEM652 and 21MTC, ensuring compatibility with a wide range of HO and OO scale models. Each version includes a compact 11 × 15 mm “sugar cube” speaker and enclosure, allowing immediate installation and high-quality sound reproduction straight out of the box.

A key feature of the LokSound 5 Fx is its ability to synchronise perfectly with motorised locomotives fitted with full LokSound decoders. This allows consistent sound behaviour across an entire train, including lighting changes, braking sounds and operational effects that match the powered unit.

The LokSound 5 Fx enables highly realistic train compositions where sound is distributed throughout the consist rather than originating solely from the locomotive. This allows for advanced operational effects such as door sounds, announcement systems, lighting transitions and brake squeal synchronisation across multiple vehicles.

In addition to sound functionality, the decoder provides multiple function outputs for lighting control, making it suitable for interior lighting, marker lights, tail lamps and other auxiliary effects commonly found in passenger and control cars.
