PIKO Sound module with loudspeaker for "BR 103"
1. Characteristics
• Intelligent Sound control with 480 second Sound
buffer
• High-resolution Sound: 22050Hz Samplerate, 12bit
• Efficient output final stage for 8 Ohm loud speaker
• Generates the operating sounds of the locomotive,
brake squeal and random noises while stationary
e.g. auxiliary aggregates
• Sound is specially adjusted to the body of the
locomotive for best resonance
• Simultaneous rendition of 8 independent sound
channels
• Additional adjustable sounds like e.g. whistle, bell,
uncoupling sound, door warning signal, or own
custom sounds
• Function Mapping up to f 28
• Switchable random sounds
• With smart start function: The Sound module stops
the locomotive decoder, when starting until the
vehicle's engine synchronize with the sound.
• Separate adjustable volume for almost all sound
events (only DS4)
• Muting with fade in and out function
• Analogue operation with start-up and shut-down
noises, when used with a suitable decoder
2. Description
The PIKO BR 103 sound modules deliver faithful
sounds like those in the original locomotives. With the
intelligent Sound control the reproduced sounds are
matched to particular operating situation.
The PIKO Sound Module plugs into the SUSI interface
of the locomotive decoder.
The intelligent sound control adapts the reproduced
sounds to the respective driving situation.
If the locomotive is to start, the sound module stops
the motor via locomotive decoder until the vehicle
starts synchronously to the sound. If the locomotive
is stopped, the squealing of the train brake sounds.
When the locomotive is at a standstill, various
operating sounds of the locomotive are played
randomly, such as fans or the like. These random
sounds are also switchable by special function key.
Due to the 4-channel technology, the driving noise of
The Sound module with loudspeaker for all loco decoders with SUSI Interface
the locomotive and 3 other locomotive-specific noises
can be switched on simultaneously via special function
key. Depending on the type of locomotive, these
can be whistles, horns, bells, door warning sounds,
or sounds recorded by the locomotive itself. The
additional sounds can also be varied in tone length -
e.g. a short switch-on pulse results in a short whistle,
a longer switch-on pulse results in a longer whistling
tone. These additional sounds can be called up via the
function keys f0 - f28. If the locomotive moves out of
the visible area of a model railway layout, e.g. into the
staging yard, the entire locomotive sound can be softly
faded out with the function "Sound off" via special
function key and slowly faded in again when the
locomotive reappears, adapted to the current driving
situation. Almost all sounds are separately adjustable
in volume by CV programming.
In conjunction with suitable locomotive decoders, the
PIKO sound modules can be used in analog operation
with motor sound.
3. Installing a Sound Module
SUSI interface
Insert the SUSI plug into the SUSI socket of your
decoder. The sound module is supplied with power
and data from the decoder.
Loudspeaker
Install the speaker in the intended opening at the
bottom of the locomotive.
Fastening the Sound module into the Vehicle
Using the double sided adhesive pad provided, affix
the decoder to the desired location in the locomotive.
The adhesive pad protects the decoder from coming
in contact with conducting surfaces and holds it in
place. Please note that according to the EMV laws the
component may only be operated in vehicles that carry
the CE symbol.
Start-up
Double check the correct installation with a
continuity tester or an Ohmmeter.
When placing the device make sure it does not come
into contact with any conducting surfaces in the
vehicle. Also ensure that a shot circuit cannot occur
when the locomotive is close, and that the wire is
not cinched.
A short circuit can destroy the component and
eventually the locomotive electronics!
4. Switching the Sound on and off
Individual sounds can be turned on and off with
special function keys on the digital center. Assignment
of sounds to the function key is done with CVs 900 -
931 of the SUSI bank 8 (CV1021 = 8). When delivered
the sounds are assigned as shown in the Table.*
Volume
The total volume of the PIKO G sound module can
be changed in the SUSI bank 2 (CV 1021 = 2) via CV
900. Therefore, first the CV 1021 is programmed to
the value 2 and then the CV 900 to the value of the
desired volume.
The individual sounds of the sound decoder are stored
in so-called slots, of which up to 32 are available
depending on the type of locomotive. The volume of
the individual sounds can be adjusted via the CVs 900
- 931 in the SUSI bank 4 (CV 1021 = 4). Therefore,
first the CV 1021 is programmed to the value 4 and
then the CV belonging to the respective sound (900 -
931) to the value of the desired volume.
All settings are factory pre-set for PIKO locomotive
decoders and for this locomotive model, but can be
easily adapted to other vehicles.
Further information can be found in the detailed
operating instructions.

5. Programming
In the factory default state all decoder options are
changed using configuration variables (CVs) according
to the DCC Stopard. The sound module can be
programmed with SUSIkomm software and Sound
Loading Adapter, or via the locomotive decoder. The
decoders can be programmed by an Intellibox, DCC
Centre and Motorola Centre. With other makes of
locomotive decoder follow the instructions for that
decoder.
Programming with DCC devices
Use the programming menu of your DCC command
station to read and program the sound module,
if it is connected to a PIKO decoder, by CV direct
programming. If programming of these high CVs is not
possible with your command station, please use the
main track programming (POM) of your DCC command
station. For the exact procedure please refer to the
manual of the used command station.
