8 LokSoundXL User Manual V2.1 05/2002

The RFI suppression inductor remains attached to the

collector terminal of the motor. Solder the other one

to terminal 1-4 of the decoder.

Connecting the speaker

The speaker must be installed in such a way that the

sound waves are not unduly blocked.

Please handle speakers with extreme care: don't

put pressure on or touch the membrane. The

speaker's magnets are very strong. Keep all metal

items away and secure the speaker firmly when

soldering. The soldering iron may pull the speaker

due the magnetic field and destroy it.

Connect the speaker to the two

terminals 1-8 and 1-9 of the

LokSoundXL module. Make

sure that you use a small

soldering iron (max. 20 W) and

only heat the marked spot as

shown in the figure (close to

the edge of the small contact

plate). Polarity is not

important. Make sure that no solder is dropped onto

the membrane.

An optimal sound effect is achieved by putting the

speaker into a sound chamber, which is supplied with

the speaker.

This will increase the sound

pressure and channel the

direction of the sound.

Without sound chamber the

sound effect may be

unsatisfactory. Feed

the speaker wires

through a small hole in

the sound chamber.

3.6 Function outputs

LokSoundXL decoder has 8 (!) function outputs. Two

are factory-set for directional headlights, the other

six (AUX1 to AUX6) can be used for auxiliary loads.

With LokSoundXL you may dim the lamps in 15 steps

to adjust the brightness optimally to your model. The

brightness of each output may be adjusted separately.

See chapter 4.2.4.2. Every function output can be

set to various blinking light effects. See chapter

4.2.4.3.

All function outputs can be individually loaded with

0,6A current but cannot exceed a total load of 2,0A.

Solder two inductors with at least 3,9 µH to the motor

terminals. You may order these as spare parts from

Märklin® under article number 516520.

For optimal operation the motor tact frequency has

to be reduced from 22kHz to 87Hz. To achieve this

set CV 9 to value 204.

Please note:

If a universal motor is connected, Back EMF

Control will be automatically deactivated. The

principle of Back EMF Control does not work

with universal motors.

3.5 Connecting the speaker

The LokSoundXL decoder may only be used with the

speakers offered by ESU electronic solutions ulm

GmbH or with speakers with the same data (1 Watt,

16 - 32 Ohms). The use of speakers by others may

cause considerable distortion and in extreme cases

even destroy the LokSoundXL decoder. We also

cannot recommend speakers that are actually designed

for use with our H0 decoder.

The correct position of the speaker is crucial to achieve

high quality sound. A speaker that is installed without

a resonance chamber will not generate good sound.

Therefore carefully select the location and sound

chamber for the speaker.
