Initial Operation
7.2.3. Selectrix® Mode
LokSound V4.0
LokSound micro V4.0
You may operate the LokSound with any Selectrix® compatible
command station with access to the functions „lights" and F1.
For programming any parameters, you must use the DCC pro-
gramming mode. It is not possible to program it with a „pure" Se-
lectrix® system. Any changes programmed in DCC are also valid
for operation with Selectrix® command stations.
As soon as a decoder receives commands in Motorola® or DCC
format (whenever it receives a signal packet with information ad-
dressed to it), the Selectrix® receiver switches off automatically.
This allows trouble-free mixed operation with Selectrix® / DCC /
Motorola®. The Selectrix® receiver turns on again as soon as the
decoder detects a power interruption.

7.3. Analogue Mode

All LokSound decoders are set ex factory to operate in analogue
mode as well.
Please take note of the remarks in chapter 10.4 if the decoder
should move repeatedly from analogue into digital sectors and
back.

7.3.1. Analogue DC operation

LokSound V4.0
LokSound micro V4.0
LokSound decoders work on conventional DC layouts. From the
factory, load compensation is active. This provides smooth con-
trol of your locomotives even at low speeds (in DC mode as well).
Since load compensation requires about 3 – 4 Volts as „base volt-
age" you must turn the throttle further than normal (=locomo-
tives without decoder) before the locomotive starts moving.

7.3.2. Analogue AC Operation

LokSound V4.0
Other LokSound decoders than the ones mentioned above are
not suitable for analogue AC mode. AC will definitely lead to
the destruction of the decoder!
Where intended, LokSound decoders support operation with AC
transformers. Therefore, the LokSound decoder can simply replace
the old directional relay. Load compensation is active (similar to DC
mode) and provides smooth control and slow-speed-performance
you have never seen before. The LokSound V4.0 recognised the
pulse for changing direction as usual. Just wait until the locomo-
tive has stopped prior to changing direction.
Never issue the „Change of Direction" command to a moving
locomotive! This could lead to damaged gears!
We cannot recommend the use of the old (blue) Märklin®
transformers that where originally designed for 220 Volt. De-
pending on their age and their tolerance range, the pulse for
changing direction could be too high in case of increased mains
voltage and therefore destroy the LokSound decoder.
Do yourself and your locomotives a favour and purchase a suitable
Märklin® transformer No. 6647 – your locomotives and decoders
will thank you with longer product life!
