This ESU LokSound 5 DCC Sound decoder is supplied blank and contains NO SOUND FILE. An ESU LokProgrammer is required to program a sound file onto this blank decoder, 

We can load an ESU sound file of your choosing onto this decoder at no extra charge. Please have a look at the available ESU sound files Click Here to go to the ESU Sound Library!


Changing the decoder CV’s can be facilitated by using your existing DCC Control System or even easier using the graphic interface of the ESU LokProgrammer which is available separately. 


NOTE : This decoder does NOT include a speaker.

Please visit our Speaker Section for a speaker suitable for all decoder brands that will best fit your installation.


ESU is proud to present the brand-new LokSound 5 sound decoder, and it is the most important member of the LokSound family. Due to the combination of the digital decoder and the sound module on one circuit board, we achieve the smallest possible dimensions of 30 mm x 15.5 mm. Therefore, it fits into almost any HO or O gauge locomotive.


The LokSound 5 DCC decoder has a DCC & DC “Dual Mode” Operation, 2 or 4 Digit DCC Addressing, 14-28-128 Speed Steps, Locomotive Consisting and up to 32 Functions. It supports all DCC programming modes including POM (Programming on the Main) and also supports RailComPlus® that allows the decoders to register themselves automatically on suitable command stations. It also allows updating the internal firmware, making it future-proof. This means, the internal software on the decoder’s memory can be replaced by new versions supplied by ESU when new features, improvements, or bug fixes are released.


You would expect excellent motor control from a LokSound Decoder, and deservedly so! It would have to have the best motor control of any decoder, as the motor control of the LokSound 5 has been further improved. A variable PWM pulse frequency ranging from 10 kHz to 50 kHz assures perfect silent operation, particularly for coreless motors. Thus, the typical hum is a thing of the past. Load control can now be adjusted with up to 10 separate CVs, and thus will manage even the most difficult cases. The unique “Auto Tune” function facilitates the automatic calibration of the decoder to perfectly match the motor. The LokSound 5 decoder supplies up to 1.5A motor current, which is sufficient even for older motor types.


The LokSound 5 decoder can reproduce up to 10 channels simultaneously. Each channel offers up to 16 Bit / 31250 kHz, and thus we have finally achieved hi-fi sound quality on your layout. A class D audio power amplifier with up to 3W output power feeds the speakers with a permitted impedance of 4 – 32 Ohms. The huge 128 MBit sound memory assures sufficient storage capacity.


Subject to the type of interface, every LokSound 5 has at least 10 amplified outputs. The decoders with PluX22 or 21MTC interface have an additional 4 outputs for controlling servos or as logic outputs. Of course, all important lighting functions are supported. The brightness of each output may be adjusted separately.
