Important Safety Notes
You have acquired a Soundswitch 2 which can be installed as part of a fully working RC
model when fitted out with suitable accessories. However, we as manufacturers have no
control over the way you build and operate your RC model, nor how you install, operate and
maintain the associated components, and for this reason we are obliged to deny all liability
for loss, damage or costs which are incurred due to the incorrect use of our products or due
to incompetent behaviour on the part of the user, or which are connected with such operation
in any way. Unless otherwise prescribed by binding law, the obligation of the GRAUPNER
Company to pay compensation, regardless of the legal argument employed, is excluded.
This includes personal injury, death, damage to buildings, damages due to loss of business
or turnover, interruption of business or other direct or indirect consequent damage whose
root cause was the operation of the model.
The total liability in all cases and under all circumstances is limited to the amount of money
which you actually paid for the product.
This Soundswitch 2 is installed and operated at the sole and express responsibility of
the operator. The only way to avoid injury to persons and damage to property is to
handle and operate the unit with the greatest care and consideration at all times.
Before you use the Soundswitch 2 for the first time please check that your private third-party
insurance policy covers you for the risks involved in operating models of this kind. If you are
not sure about this, it is best to take out a special policy to cover modelling risks.
These safety notes must be kept in a safe place. If you ever dispose of the Soundswitch 2,
be sure to pass them on to the new owner.
The following points are important, and must be observed at all times:
•The Soundswitch 2 is not suitable for young persons under fourteen yeas of age.
•Check that the radio control system components and all other plugged connections are
firmly seated and secure before you run the model for the first time.
•Ensure that the channel you wish to use is not already in use. Never switch your model
on if you are not certain that your channel is free.
•Please bear in mind that radio apparatus and transmitting systems can have a serious
adverse effect on your model’s proper function. As far as possible, ensure that no
equipment of this type is operating in the vicinity while you are running your model.
•Do not exceed the recommended operating voltage. Higher voltages may ruin the
Soundswitch 2.
•Do not subject the Soundswitch 2 to high levels of humidity, heat, cold or dirt.
•Always take great care to keep your model watertight. Allow the model to dry out
thoroughly after each run.
Care and maintenance
•Any water which enters the model should be allowed to drain out by opening the hatch
cover. If water gets inside the Soundswitch 2, dry it out carefully then send it to your

Introduction
The Sound module SOUNDSWITCH 2 was developed for the RC model construction in
order to equip models, with an as realistic as possible, speed-dependent engine sound (e.g.
engine sound). To make the background noise perfect, in addition to the engine sound, up to
16 additional sounds can be played. Moreover automatic turn on-, turn off-, starting-,
stopping-, idling-, braking- and engine noises can be played. In addition 8 easy configurable
random sounds are possible as well.
The sound output occurs on this module with 4 channels, which means in addition to the
engine sound, 3 further additional-/random sounds can be played simultaneously.
Information of the driving speed (up to 255 steps!) can either be taken from 1 to 2 motors
(analogue and mix mode), or 1 to 2 proportional channels (digital mode) of the receiver are
used for the speed information.
Each sound can be changed at any time on the Sound module. For this purpose, just a
Windows PC with an USB port and our software "USM-RC Sound-Teacher" is necessary.
You can use this Sound module for a variety of models.
An efficient audio amplifier is already available on the board. Therefore only a loudspeaker is
needed to be connected for the sound output.
In addition there are 7 switching outputs for the connection of LEDs, lamps, relays for
example. Furthermore different light effects (light, stop light, indicators, hazard warning light,
MG fire, flickering-light and so forth) can be implemented at these outputs.
Safety notes
•Please read this operating manual carefully and keep it for future use!
•The integrated circuits on the Sound module are sensitive to electrostatic charge.
Therefore it is important that you don’t touch these components, before you do have
discharged yourself (e.g. through a grip onto a grounded device).
•In order to guarantee an interference-proof operation, the Sound module should be
built in a suitable case.
•The Sound module should be only used with supply voltages, which are given in the
technical data.
•Always switch off power first before connecting the module!
•The Sound module is not suitable for children under 14 years.

Operating Modes: Digital, analogue and mix mode
In order to make the Sound module universal usable, 3 different operating modes are
available. The operating mode is very important for the possible functions and especially for
the connection of the Sound module. Therefore it should be decided at the beginning which
one of the two operating modes is better suitable for the used model. The selected operating
mode of the Sound module is set in the USM-RC Sound-Teacher (see page 37).
If possible, please use the digital or mix mode, owing to their extended selection of functions.
Digital mode:
The digital mode is always applied if you use standard RC remote control radios and
receivers with PPM-signals. In this case the Sound module is connected directly to the RC-
receiver, and it recognizes the driving speed directly from 1 or 2 proportional channels
(parallel to the speed controller). Via 2 more proportional channels up to 12 additional
sounds can be played. In addition the engine sound can be switched on and off, the volume
can be adjusted as well as light and indicators can be operated. Furthermore 4 more
additional sounds can be played via digital switching inputs.
Analogue mode:
The analogue mode is used, if you don’t have „standard” RC equipment.
In the analogue mode the driving speed is determined by a voltage measurement at 1 or 2
motors. In order to activate additional sounds or to turn on and switch off the engine sound
the digital switching inputs of the Sound module must be connected (e.g. with switching
modules).
Unfortunately due to the missing proportional channels, a few functions are not possible in
the analogue mode. For instance you can activate just 6 additional sounds with 6 switching
inputs. In addition the light and the volume cannot be switched or controlled in this mode by
the remote control.
Mix mode:
The mix mode is a combination of digital and analogue mode. Like in the analogue mode the
driving speed is determined directly by the motor voltage. However, the proportional
channels #2 - #4 still working in digital mode and can interpret straight signals of the RC
receiver.

Installation of the Sound module
In order to fix the Sound module in the model, 2 mounted holes with Ø 2,1mm are available.
Please pay attention that no components or conducting paths of the board touch any metal
parts during the installation of the module! This can cause short-circuits which can destroy
the Sound module and connected devices.
Connection of the Sound module
The connection of the supply voltage, the loudspeaker and the outputs are always identical,
independent on the used mode (digital, analogue or mix mode).
By contrast the remaining wiring is dependent on the operating mode.
Always switch off power before connecting the module!
The terminal X1 is a spring cage terminal which allows a fast and simple connection of the
Sound module. To put a wire in or out, you simply push from above onto the actuating lever
of the terminal with a small screwdriver. The wires should be approximately 7-8mm stripped
and should ideally be tin-plated prior the connection.
Connection of the supply voltage (battery):
The Sound module is designed for a DC voltage from 5V to 14V. Just connect terminal X1/4
with the positive pole and terminal X1/5 with the negative pole of the supply voltage. If the
supply voltage is connected correctly, the green LED at the Sound module is glowing.
We recommend switching a fuse (3,15A) to the power line as well, in order to avoid serious
damages at your model or the Sound module in case of a wrong wiring or another defect.
As a further option you can also connect a switch into the power supply of the Sound module
to make it powerless. In particular the switch offers an advantage with battery used models, if
you don’t need sound effects for a long period.
Connection of the loudspeaker:
The positive pole of the loudspeaker should be connected with the terminal X1/1 the negative
pole with the terminal X1/2.

13
Connection of the outputs:
The 7 outputs of the module are located at the pin connector X3. We recommend using the
supplied attachable ribbon cable. Of course you can also connect other wire/plugs to the pin
connector. For every output 2 pins are available, at which the load (e.g. lamps, LEDs, small
engines) can be connected.
The positive pole is located at the pin of the board edge; the output (switched negative pole)
is located next to the pin.
Output Ribbon cable
#1 brown (-) red (+)
#2 orange (-) yellow (+)
#3 green (-) blue (+)
#4 purple (-) grey (+)
#5 white (-) black (+)
#6 brown (-) red (+)
#7 orange (-) yellow (+)
In order to receive the right cable colors, the ribbon cable must be put on correctly to the
connector. Theoretically it could be put on rotated by 180°; however, the configuration would
be changed in this case. To put the cable on correctly the brown wire must face upwards
(board middle), the yellow wire downwards (board edge).
The switched voltage at the outputs is always as high, as the supply voltage of the Sound
module. For example if the Sound module is supplied with 12V, only lamps with 12V should
be connected. If you want to connect LEDs, series resistors are always required. In addition
attention must be paid at LEDs to the correct polarity. The series resistors for the LED’s are
depended on the supply voltage, the LED-color and the LED-current. Modellers familiar with
electronics will certainly be able to calculate the ideal value for the models’ LEDs, but
everyone else should refer to the table below, which shows the resistance values required for
standard LEDs (approx. 15mA rating):
Supply voltage Series resistor
6V 270 Ohm
7,2V 330 Ohm
8,4V 470 Ohm
9,6V 510 Ohm
12V 680 Ohm
If multiple LEDs are connected to one output (e.g. front and rear direction indicators), it is
always better to use separate dropping resistors than to wire the LEDs in series.

14
Connection of an external audio amplifier (optional):
To the terminals X1/1 and X1/3 an additional audio amplifier can be connected. We
recommend using our audio amplifier Order No. 2383. This amplifier is optimally
designed for the SOUNDSWITCH 2 Sound module. Of course other amplifiers can
be connected as well; however, this requires an additional voltage divider to break
the audio-voltage to the amplifier required audio-input voltage.
General references to the wiring in the model:
Unfortunately the speed controllers and motors in the model are often strong
interference sources, which could disturb the electronic of the Sound module or the
sound output (whistles, humming in the loudspeaker). Therefore all motors should
be absolutely interference-suppressed!
It is also important to pay attention, to best possible „clean" wire routing. You
should use always short wires and avoid any unnecessary loops. The wires for the
supply voltage of the Sound module, should be connected to the driving-battery as
direct as possible, and not connected over the same wires with other devices or
speed controllers.

15
Connection of the Sound module in digital mode
Connection of the proportional channels
Up to 4 proportional outputs of an RC receiver can be attached to connectors X2/1 - X2/4.
Just use the 2 supplied servo patch cables for the connection. If more than 2 proportional
channels should be connected, further servo patch cables are required. For your
convenience the cables can be purchased in our online shop.
A special label on the board indicates the locations of the 4 channels. The channels #1 and
#2 are labeled twice, so as to transmit the proportional signal straight to the speed controller
or servo. Y-cables are needed if further speed controllers or servos should be connected to
the channels #3 and #4.
Please attach the servo patch cables to the Sound module with the brown wire face the
board edge (to the right) and the orange wire to the board middle (to the left).
Following functions can be triggered with the 4 proportional channels on the Sound module:
Channel Model with 1 motor Model with 2 drive motor
#1 speed-dependent
engine noise

If you have a model with 2 motors (e.g. chain vehicle) and use the proportional channel #2
for the driving speed identification, unfortunately it is not possible to activate the additional
sounds 9-12 with this proportional channel. Also no outputs for light, indicators and hazard
warning light can be used.

16
Connection of the switching-inputs
At the terminals X1/7 - X1/10, the additional sounds 13-16 can be triggered. To activate a
sound, the negative pole of the supply voltage must be connected to the respective input.
Generally switch modules are used for this (as our RC-SM-2 or other standard multi-switch-
modules). If the switch modules are negative switched (usually they are) they can be directly
connected to the inputs of the Sound module.
Terminal X1/6 is the switching-input, to turn on and off the engine sound. For switching,
simply the negative pole (e.g. by a switch module or switch) must be connected to this input.
In the digital mode, the engine sound can be directly switched with the proportional channel
#4, the one-channel multifunction selection or the nautic mode.
The engine sound is always switched off, if neither the terminal X1/6 nor the proportional
channels #3 or #4 are connected and switched on for the engine sound.

17
Connection of the sound operation in analogue mode
Connection of the motors
In the analogue mode, the driving speed is determined by the motor voltage. 1 or 2 DC
motors can be connected to the terminals X1/7 / X1/8 and X1/9 / X1/10. The connection to
the Sound module is implemented parallel to the existing connections of the speed
controllers which powers the motors.
Only if you want to use the output for the reverse driving light you have to pay attention to the
polarity of the motor connections. If the reverse driving light shines at the forward drive, the
connections must simply be changed.
If only 1 motor is connected, the terminals X1/9 and X1/10 can be used as switching-inputs,
for 2 more additional sounds and indicators.
Connection of the switching-inputs
At the connectors X2/1 - X2/4, the additional sounds 13-16 can be triggered. The input pin is
the left pin (direction board middle). The other two pins have no function.
To activate a sound, the negative pole of the supply voltage must be switched to the
respective input. Usually switch modules are used for this (as our RC-SM-2 or other standard
multi-switch-modules). These switch modules are all negativ-switched, therefore the outputs
of the switch module can be connected to the inputs of the Sound module.
Terminal X1/6 is the switching-input, to turn on and off the engine sound. For activation, the
negative pole (e.g. by a switch module or switch) must be connected to this input.
If this switching-input is not connected, the engine sound is always switched off!

18
Connection of the sound operation in mix mode
Connection of the motors
In the mix mode, the driving speed is determined by the motor voltage like in the analogue
mode. 1 or 2 DC motors can be connected to the terminals X1/7 / X1/8 and X1/9 / X1/10. The
connection to the Sound module is implemented parallel to the existing connections of the
speed controllers which powers the motors.
Only if you want to use the output for the reverse driving light you have to pay attention to the
polarity of the motor connections. If the reverse driving light shines at the forward drive, the
connections must simply be changed.
If only 1 motor is connected, the terminals X1/9 and X1/10 can be used as switching-inputs,
for 2 more additional sounds and indicators.
Connection of the switching-inputs
Up to 3 proportional outputs of an RC receiver can be attached to connectors X2/2 – X2/4.
Just use the 2 supplied servo patch cables for the connection. If more than 2 proportional
channels should be connected, further servo patch cables are required. For your
convenience the cables can be purchased in our online shop.
A special label on the board indicates the locations of the 4 channels.
Please attach the servo patch cables to the Sound module with the brown wire face the
board edge (to the right) and the orange wire to the board middle (to the left).
Following functions can be triggered with the 3 proportional channels on the Sound module:
Channel Function
#2 additional sounds 9-12
light, indicator, hazard warning
#3 additional sounds 1-4
one-channel multifunction selection

Functional assignment at proportional channels #1- #4
The proportional channel #1 is responsible only for the speed recognition. The other 3
channels have several functions. If channel #2 is used also for the speed determination, the
other functions (light, indicators and additional sounds 9-12) are not available.
To occupy the proportional channels
#2 - #4 with several functions, these
channels are split into 5 areas "A, B,
N, C and D". These areas represent
the possible positions of a joy-stick.
The area N is the neutral position that
is the center position of the joy-stick.
The same principle is also valid for a
horizontal joy-stick. The area A is in
this case to the left and area D to the
right.
The areas can also adjusted/
optimized to your remote control, by
setting the 4 thresholds in the USM-
RC Sound-Teacher.

Of course, you do not have to use all the functions listed here. This overview should just
show all the possibilities of the channels #2 - #4.
In order to activate the additional sound 5 for example, the joy-stick of proportional channel
#4 must be brought from center position N to position A. This movement should be done
quite fast (< 0, 5s), because during this movement the joy-stick passes also the area B. If
you move the joy-stick too slow, the additional sound 7 would be played as well.
Neutral position of channel #1
In order to play the right driving sound, the neutral position of channel #1 must be correctly
set at the Sound-Teacher. On page 48 you can see how the setting can be used.
Neutral position of channel #2 - #4
In general, remote control manufacturer do not define a standard neutral position, due to this
lack you can configure several neutral positions for the channels #2 - #4 (if you use two
engines it is #3 - #4) with the Sound-Teacher by your own, varied from 1.3 to 1.7ms.
In addition it is possible to recognize the neutral position automatically at the turn-on
procedure. It is important to ensure that the remote control position is at the neutral position
otherwise wrong data are used. Please check the right position before switching on the
Sound module.
Tips:
You can check the data your Sound module receives from your remote control when you
connect the Sound module to your PC and start the Sound-Teacher over the menu “Help”
and “Diagnosis”. This can be helpful to find a malfunction as well. Furthermore it is a good
practice to learn how to control the 5 areas A, B, C and D over the remote control.
