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 LokSound micro V4.0 will be either shipped as 6-pin NEM651 or 8-pin NEM652 plug version. For the first time we also offer the new wireless Next18 interface version. Every LokSound micro V4.0 decoder comes with a new 16mmx25mm loudspeaker (0.6 x 1.0 inch) plus sound chamber.
Operational mode
The LokSound micro V4.0 recognises 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. You can assign the decoders to 2-digit, 3-digit (1-127) or 4-digit (1-9999) addresses as well as a consist address.
The Motorola®-protocol provides the operation of the LokSound micro V4.0 decoders with Märklin® control stations 6020®, 6021®, delta®, mobile station® and central station®.
The decoders can be used with the addresses 01 – 255 on this mode. A second address provides the possibility to use the function keys F5 to F8.
The Selectrix® protocol provides the possibility to use LokSound V4.0 decoders with this also established system.
All established DCC brake systems like the well-known Lenz® LG100, but also the new Lenz® ABC brake units with asymmetrical DCC signal are recognised as well as the braking on DC (with switched polarity) or on Selectrix® diode brake systems.
Of course, our top decoder is able to determine a constant braking distance, so that your locos stop in front of the red signal, no matter what speed your loco is at.
The decoders can switch automatically between all modes (Motorola®, DC, DCC, Selectrix®) during operation. This is important if some parts of your layout work with analogue control (e.g. fiddle yards).
Motor management
From a LokPilot decoder, you rightly expect an excellent motor management. With the LokPilot micro V4.0, ESU introduces the once more improved fifth generation of load control.
The standard frequency is adjusted adaptively to the speed with a basic frequency of 40 kHz. The result is an even better slow driving performance. Your locos will crawl super slowly - thanks to the 10 Bit A/D convertor.
With Dynamic Drive Control (DDC) you can limit the influence of back EMF and glide smoothly around the depot area and over turnouts; while on the main, when going uphill, the engine slows down prototypically.
The load control is well-prepared for all customary motor types, such as ROCO®, Fleischmann®, Brawa®, Mehano®, Bemo®, Märklin®, Faulhaber® or Maxon® motors. 0.75A steady load is more than the above-mentioned motos need and offers enough energy reserves, even for longer block trains.
Sound
The most important element of the new LokSound micro V4.0 decoder is the sound chip. This is why we have equipped the decoder with an enormous memory of 32 MBit to save up to 276 seconds of original sounds. The LokSound micro V4.0 works with 8 polyphonic channels, i.e. that the decoder is able to play up to 8 different sounds simultaneously, using the 16-Bit mixer and the nearly noiseless D/A convertor.
So we can provide a much better monitoring of the original locomotive´s complex elements as it is possible to combine several channels. You will notice the difference immediatly! The sounds will be amplified up to three times louder than before by using a new digital „class D“ amplifier. The speakers haven´t been left unchanged, too.
We also changed from the old type of speakers to speakers with an impedance of 4 Ohms. Use our provided stock of new developed speakers!
All single sounds of the LokSound micro V4.0 can be mixed in volume individually on nearly every digital control station.
The new super flexible sound engine without static schedule provides a very prototypical simulation of all railroad vehicles.
Analogue mode
LokSound micro V4.0 decoders can be used on DC ayouts as well. The motor and the synchronisation of all driving-, sound- and light functions will be controlled in analogue mode, too!
So, model railroaders without digital systems can enjoy the LokSounds, despite the sounds on function keys.
Functions
LokSound micro V4.0 decoders have 4 function outputs with the possibility of using constant current of 150mA. These outputs can be assigned individually. Apart from that, there are two more non-amplified outputs with logic level. All important light functions like Flash, Gyrolight, Mars light, fire box and so on are provided including the individual adjustment of brightness for each function.
Of course, the decoders provide automatic coupling and decoupling for couplers by Roco®, Krois® and Telex® and from now on even a full beaming head light function.
The LED mode controls the right light effects when using LEDs.
Safe operation
If desired it is possible to connect a PowerPack (ESU Art.No. 54670) to the LokSound micro V4.0, as to all other ESU decoders of the 4th generation. This energy storage continues to supply the decoder with energy if the power consumption is not optimal due to dirty tracks.
RailComPlus®
A very important function of the LokSound micro V4.0 decoder is the integrated RailComPlus® function. Your locos will be recognised automatically by an appropriate digital command station fast as lightning and will receive, if needed, a new address. Forget about the cumbersome typing and programming!
Protection
Of course, all function outputs and the motor current output are overload protected. We want you to have fun with your decoder as long as possible!
Future built-in
You can update the firmware of the LokSound decoders. This means, the internal software on the decoder‘s memory can be replaced by new versions if necessary. You‘ll simply need the ESU LokProgrammer and a PC.
Sound variations
ESU, as the technologic and market leader takes your requirements for sound very seriously. There are already more than 200 sound variations available for the LokSound micro V4.0.
ESU is extending the sound library all the time and provides all sounds on our homepage for free download.
