would like to introduce our newest LokSound decoder.
At first glance, it appears to be a normal
representative of its kind. However, the decoder´s
unique inner values make it a first choice for model
railway fans looking for maximum compatibility with
all common digital systems.
LokSound V4.0 M4 is the world´s first Quad-protocol
decoder! Aside from DCC, Motorola® and Selectrix®,
all incorporated into the LokSound V4.0, the
LokSound V4.0 M4 also speaks the M4 protocol! Thus
the decoder is a 100% compatible to all mfx®-capable
command stations on the market. It will be
automatically recognised and can be fully
programmed.. That´s why the decoder is “first
choice” for all Märklin fans who do not want to miss
out on mfx®.
ensure that almost all locomotives can be retrofit
with this multi-talented decoder, we offer the
LokSound V4.0 M4 with many different interfaces such
as 8-pin, 6-pin or PluX12 plug as well as wireless
21MTC or with a PluX16 interface as well as versions
with PluX22 Interface for the latest Fleischmann® or
LokSound V4.0 M4 is a real multi-talent. It speaks 4
data protocols and can thus be really used anywhere.
Except during DCC operation with RailComPlus®
recognition, the decoder will be automatically
recognised by Märklin® command stations via the M4
protocol. For owners of older layouts, the decoder
has additionally been equipped with the well-known
Motorola® and Selectrix® data format.
LokSound V4.0 M4 can be also used on analogue DC or
AC layouts. The built-in motor control will learn
the motor manners and synchronise the drive and
lighting functions with the sound functions. So,
model railroaders without a digital system can also
enjoy the LokSound decoders, of course, despite the
sounds triggered by function keys. No matter with
which command station you operate the decoder it
will always be perfectly integrated. Thanks to its
M4 recognition, it will be automatically detected by
Märklin Central Stations® and 16 functions will be
available. Of course you´ll be able to adjust all
parameters with your command stations as you are
used to do.
During DCC operation there will be up to 28
functions available. The decoder will be
automatically recognised in a matter of seconds by
an ESU ECoS with RailComPlus® detection and show all
functions as well.
Owners of the “older” Märklin® 6021 will be not
excluded for sure. 4 addresses per decoder enable to
switch up to 16 functions. A built-in programming
mode makes reprogramming ,even with this dignified
command station, possible. Last but not least it
should be remembered that the decoder can be
operated reliably with Selectrix® command stations.
of this sounds far too good to be true? It gets even
better: The LokSound V4.0 M4 decoder recognises all
common break systems, such as the Märklin® break
system, the Lenz® ABC break system (with slow drive
function!), Selectrix® diode break systems or ZIMO®
HLU® systems: the decoder will always recognise the
desired operational mode full-automatically. For us
being the creator of this function, it is a matter
of honour that during braking a constant distance
can be defined.
expect an excellent motor control from a LokSound
Decoder and deservedly so! LokSound V4.0 M4 is
equipped with the 5th generation of load control.
You can adjust the control frequency adaptively to
the speed. So many motors will run even better and
softer. You can determine a limitation of the load
control‘s influence with the Dynamic Drive Control (DDC)
to control very accurately in station or shunting
switch areas. Uphill running also appears very
natural with it.
most important element of the new LokSound V4.0
decoders is the sound chip. This is why we have
equipped the LokSound V4.0 M4 with an enormous
memory of 32 MBit to save up to 276 seconds of
original sounds. The LokSound V4.0 M4 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
we can provide a much better monitoring of the
original locomotive´s complex elements as it is
possible to combine several channels. You‘ll
recognise the difference at once! The sounds will be
transmitted to the loudspeaker using a new digital
„class D“ amplifier. Combined with the ESU high
performance speakers (with an impedance of 4-8 Ohms)
you will achieve an unprecedented sound quality!
Each individual sound can be mixed in volume
independently via CVs.
LokSound V4.0 M4 decoders have six (6) function
outputs, each with a constant current of 250mA. The
versions with 21MTC interface have two more
non-amplified outputs with logic level to meet the
NEM 660 standards. 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. These features will, of course, also work with
mfx® command stations (e.g. Märklin® Central Station
desired, it is possible to connect a PowerPack (ESU
54670, see page 62) to the LokSound V4.0 M4, as to
all other ESU V4.0 decoders. This energy storage
continues to supply the decoder with energy if the
power consumption is not optimal due to dirty
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!
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.
as the technologic and market leader takes your
requirements for sound very seriously. For the
LokSound V4.0 M4 decoders, all sounds created for
the 4th generation of LokSounds can be used - or
projects that have been created for a LokSound V3.0
M4 can be converted just by a few mouse clicks.
There are already more than 200 sound variations
available. ESU is extending the sound library all
the time and provides all sounds on our homepage for
