LokSound 5 L DCC/MM/SX/M4 “Blank decoder”, PInheader with adapter, Retail, Gauge: 0 – #397-58315 – SPECIAL ORDER


Brand: ESU


LokSound 5 L is intended for use in all applications where the required power exceeds the limits of LokSound 5.  Ideally these are 0 gauge vehicles and also smaller 1 gauge locomotives. Despite its compact dimensions of only 50.8 mm x 25.4 mm x 14 mm it is equipped with a dual speaker output and integral PowerPack.

The LokSound 5 is equipped with a multi-pin connector and is supplied ex works with an adapter board featuring solder pads. 

Operating modes

Like all products of the LokSound family the LokSound 5 L is a true multi protocol decoder. It supports DCC as well as Motorola®, Selectrix® and M4. Of course it supports 14 through to 128 speed steps as well as 2 and 4 digit addresses in DCC format and up to 32 functions. Thanks to RailComPlus® the decoders register themselves fully automatically on suitable command stations.

This decoder supports all DCC programming modes and thanks to RailCom® you may read out the CV values on the main, provided you have a command station supporting RailCom®. There are utility registers for command stations that only facilitate programming of CVs ranging from 1 to 255.

Motorola® users benefit from up to 28 speed steps and 255 addresses. Three additional Motorola® addresses facilitate triggering of 16 functions. An integral programming mode even allows programming with the good old Control Unit 6021.

The M4 protocol supports the automatic registration on mfx® compatible central units.

The LokSound 5 L decoder supports Märklin® braking sections just as well as the ZIMO® HLU braking commands or the Lenz® ABC system. Braking with DCC brake generators or with DC is also possible. Furthermore the locomotive with a LokSound 5 L will come to a halt when a Selectrix® braking diode is switched into the circuit. The ABC push-pull feature enables automatic commuting between two stations.

The LokSound 5 L decoder is also suitable for analogue DC and AC layouts.


The LokSound 5 L decoder can reproduce up to 10 channels simultaneously. Each channel offers up to 16 Bit / 31250 kHz and thus we have finally achieved hi-fi sound quality on your layout. For all practical purposes one cannot detect any difference to the original. A dual class D audio power amplifier with up to 2-times 3W output power feeds the speakers with a permitted impedance of 4 – 32 Ohms. The huge 128 MBit sound memory assures sufficient storage capacity.

The volume of all individual sound fragments may be adjusted separately. The outstandingly flexible sound engine without a rigid flow chart facilitates a prototypical simulation of all conceivable rail vehicles. Three separately adjustable braking functions and two alternative load scenarios provide you with maximum control of your vehicles.


Every LokSound 5 L decoder has 11 amplified function outputs. On top of that there are another 6 logic outputs, which can, if so desired, control two RC servos or SUSI extension modules. Of course, all important lighting functions are supported. The brightness of each output may be adjusted separately. The decoder supports the automatic push and pull movements – known as the coupler waltz – required for the reliable function of digital couplers such as the ones by ROCO® and Krois® as well as Telex® couplers. 4 sensor inputs may be employed in order to trigger functions.

Motor control

Motor control of the LokSound 5 L has been further improved. A variable PWM pulse frequency ranging from 10 kHz to 50 kHz assures perfect silent operation, particularly for coreless motors. Thus the typical hum is a thing of the past. Load control can now be adjusted with up to 10 separate CVs and thus will manage even the most difficult cases. The unique “Auto Tune” function facilitates the automatic calibration of the decoder to perfectly match the motor. The LokSound 5 L decoder supplies ample current for the motor, namely up to 3.0 A.

LokSound 5 L DCC

The LokSound 5 L DCC is made for the North American and Australian markets. It is a pure DCC Decoder, which supports RailComPlus and can also be used on DC layouts.
