3.1.3.1 Connecting DC motors
• Connect the orange wire with the motor termi-
nal, that was originally wired to the right wheel
pick-up (center pick-up in AC models).
• The gray wire goes to the terminal, that was
originally connected to the left wheel pick-up
(common rails for AC models).
• Exchanging the wires changes direction of travel.
• Some engines with the Märklin® 5-pole high
performance drive may have 3 RFI suppressors
soldered to the motor shield.
• The two suppressors that connect the motor
terminals with the motor chassis must be
removed (see figure 4).

3.1.3.2 Connecting universal motors
Figure 5 shows how a universal motor (e.g. AC motor
by Märklin®) is connected to a LokSound decoder:
• Connect the orange wire with the motor terminal
that was originally connected with the center
pick-up.
• Connect the gray wire to the motor terminal that
was originally connected to the common / wheel
pick-up.
• Exchanging the wires will change direction of
travel.
• Solder an inductor (choke) with at least 3.9 mH to
each motor terminal. They are available as spare
parts from Märklin® under article number 516520.
• The RFI suppression inductor remains attached to
the collector terminal of the motor and has to be
soldered to the blue wire.
Please note: If a universal motor is connected
LokSound will automatically deactivate Back
EMF Control. The principle of Back EMF
Control does not work with universal motors.
3.1.4 Connecting the speaker
speaker
chamber
LokSound decoders may only be used with the
speakers supplied by ESU GmbH & Co. KG . They
have an impedance of 100 Ohm. The use of speakers
from others manufactures may cause considerable
distortion and in extreme cases, may even destroy
the LokSound decoder.
The correct position of the speaker is crucial to
achieve high quality sound. A speaker that is installed
without a sound chamber will not generate good
sound. Therefore carefully select the location and
sound chamber for the speaker.
The speaker must be installed in such a way that the
sound waves are not unduly blocked.
