2. Characteristics of the LokSound
decoders
The LokSound decoder is a universal electronic module
for installation in model engines of most common
scales. We recommend LokSound for all engines in
TT, HO gauge as well as smaller engines in O gauge.
LokSoundXL is best suited for larger scales such as O,
I, II and G gauge. ESU LokSound decoders revolutionize
any model train layout. They intelligently combine a
sophisticated digital decoder and a digital sound
module. With LokSound you can run your engine with
load control and many auxiliary functions while
enjoying the original sound of the prototype. Its unique
features provide flexibility and safety in operation
that you have come to expect from a state of the art
decoder. Even future standards are no problem for
LokSound: its flash technology allows adaptation to
the latest developments.
Multi-protocol operation: LokSound decoders und-
erstand both, the commonly used Märklin® /
Motorola® – format and the NMRA / DCC - system.
Thus LokSound may be used with almost all currently
available digital command control systems. Amongst
others LokSound was tested with:
• Digitrax® systems
• Lenz Digital Plus®
• ROCO® digital is cool®
• Atlas® commander
• Bachmann® E-Z command®
• Märklin® 6021
• Uhlenbrock® Intellibox (DCC+Motorola® System)
• ZIMO MX-1 (DCC-Operation)
• Fleischmann® Twin-Center
• LGB® MTS® control
Automatic change between all four operating modes
during operation (AC , DC , DCC digital, Märklin®
digital)
Universal motor connection: All types of motors
commonly used for model trains may be connected
to LokSound:
• DC motors (e.g. Bühler, Mabuchi, etc)
• Coreless motors (e.g. Faulhaber, Maxxon, Hitachi)
• Alternating current motors (AC motors)
High motor pulse frequency: The pulse frequency
of 32 kHz (!) assures absolutely smooth running. Thus
the motor runs silently and without any whine, heat
generation is minimized and lifetime is prolonged.
Even coreless motors may be operated with LokSound
decoders without any problem.
Motor control: LokSound offers fourth generation
load control. It may be adapted to suit each individual
motor and can be switched off. Suitable for DC motors
and coreless motors. Therefore your engine will always
travel at the selected speed, no matter how large the
load is or whether the engine is traveling up or down
gradients.
Dynamic Drive Control (DDC): back EMF active at
low speeds for smooth slow running with reduced
influence at high speeds.
Back EMF for conventional operation: Back EMF
is also active in conventional AC or DC mode. The
user has full control of motor and acceleration.
4 function outputs: In addition to the two lighting
outputs, two more function outputs are available:
switch on a smoke generator or the interior lighting
or activate a digital coupler by pressing a button!
Lighting effects and individually dimmable lamps help
to make your models even more prototypical you
will have lots of fun.
Revolutionary function mapping: All functions can
be allocated to any of 20 function buttons. Multiple
allocations are possible allowing for the combination
of sound and functions, e.g. the sound of shoveling
coal and light flickering in the firebox. Also, we have
integrated the latest NMRA DCC standards covering
the use of F13 - F20
Helper mode for consisting: With the Helper
Function the user can select whether the engine runs
standalone, head-of-consist, mid-of-consist or end-
of-consist.
Consist mode CVs: influence the behavior of the
function keys with the added CV 21 and 22.
Brake sections: LokSound decoders recognize (and
respond to) the most common brake systems: besides
the Lenz brake generator, the Märklin® brake track
is also supported.
Circuit protection: the motor output and all function
outputs are short circuit protected .
