ESU LokSound V4.0 Micro Decoder - 8 Pin



ESU V4.0 Sound decoder programmed with the DCC Solutions Custom Sound Project to suit your locomotive.

Decoders Available:  Loksound V4.0 Micro 8 Pin Plug

LokSound V4.0 decoders help many H0 model railroaders to operate their locos with realistic sounds, something that friends of the smaller N and TT gauges don´t need to do without. We even once more reduced the new LokSound micro V4.0 decoder´s dimensions compared to its forerunner. With a size of only 25mm x 10.6mm x 3.8mm it is the world´s smallest LokSound decoder!

Since there are also no more mechanical obstacles in the way, it is a pleasure to enjoy all the decoder´s features: the LokSound micro V4.0 incorporates a complete digital decoder, which, besides DCC and Motorola®, also understands Selectrix®. Beside the two light outputs we were even able to integrate a sound-section, equal to that of its bigger brothers and two user selectable function outputs.

The most robust and reliable decoder on the market that offers the user trouble free operations with all function outputs and the motor current output overload protected. ESU wants you to have fun with your decoder for as long as possible! A fully programmable decoder allowing you to create, modify and add your own sounds to the sound file. 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.

The LokSound V4.0 recognizes DCC, Selectrix® and the Motorola® protocol. It can be operated with 14, 28 or 128 drive steps or on analogue DC layouts in DCC mode. LokSound V4.0 decoders are also able to operate on analogue DC and AC layouts. You can assign the decoders to 2-digit, 3-digit (1-127) or 4-digit (1-9999) addresses as well as a consist address.

You expect an excellent motor control from a LokSound Decoder and deservedly so! It would have to have the best motor control of any decoder. Here at DCC Solutions we have tweaked and programmed the decoder to provide super slow speeds perfect for those who like their locos to move off slowly or like to operate shunting. So many motors will run even better and softer with the LokSound V4.0.

The most important element of the new LokSound V4.0 decoders is the sound chip. with an enormous memory of 32 MBit to save up to 276 seconds of original sounds.

The LokSound V4.0 works with 8 polyphonic channels, allowing the decoder is able to play up to 8 different sounds simultaneously, using the 16-Bit mixer and the nearly noiseless D/A convertor.

And of course, let’s no forget the 4 function outputs with the possibility of using constant current of a 150mA. These outputs can be assigned and controlled individually for the use of lights,they provide full support for all lighting functions and brightness.


The LokSound V4.0 is blank decoder that requires the sound file to be programmed onto the decoder. So lets us know what locomotive the decoder is intended for and we will provide you with the correct version of the V4.0 to fit inside the loco and load the sound project.

We have a large selection of Custom Sound Projects designed to suit the sounds of Australian locomotives as well as all the sound files available from ESU for American and European Locomotives. :D
