GB Sound module USM-RC Introduction The sound module USM-RC was developed for the RC model construction in order to equip models, with an as faithful as possible, speed-dependent driving sound (e.g. engine sound). To make the background noise perfect, in addition to the driving sound, up to 16 additional sounds can be played. Automatic turn on-, turn off, starting-, stopping-, idling-, braking- and driving noises can also be played. Also another 8 conveniently configurable random sounds are possible.

GB Sound module USM-RC Operating Modes: Digital- and analogue operation In order to make the sound module as universally usable as possible, 2 different operating modes are available. Since the operating mode is very decisive for the possible functions, and particularly for the connection of the sound module, it should be decided now at the beginning, which one of the two operating modes is better suitable for the respective model.

GB Sound module USM-RC Installation of the sound module In order to fix the sound module in the model, 2 mounted holes with Ø 2,1mm are available. Pay attention that no components or conducting paths of the board touch any metal parts during the installation of the module! This can induce to short-circuits which can destroy the sound module and connected devices.
GB Sound module USM-RC Connection of the outputs: The 7 outputs of the module are on 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. Per output there are always 2 pin's availably, at which the load (e.g. lamps, LEDs, small engines) can be connected. The pin at the board edge is the positive pole, next to the pin is the output (switched negative pole).
GB Sound module USM-RC Connection of an external audio amplifier (option): To the terminals X1/1 and X1/3 an additional audio amplifier can be connected. We recommend using our PV-20W as audio amplifier. This amplifier is optimally designed for the USM-RC sound module. Of course also other amplifiers can be connected, but a voltage divider which divides the audio-voltage, to the voltage of the audio-input, of the used amplifier is needed.
GB Sound module USM-RC Connection of the sound module in digital operation Connection of the proportional channels At connectors X1/1 - X1/4 up to 4 proportional outputs of an RC receiver can be connected. You use the 2 supplied servo patch cables for the connection. If more than 2 proportional channels should be connected, further servo patch cables are needed, which you can order in our shop. There is a labeling that characterizes where the 4 channels on the board are.
GB Sound module USM-RC Terminal X1/6 is the switching-input, with which the engine sound is turned on and off. For switching, simply the negative pole (e.g. by a switch module or switch) must be connected to this input. In the digital operation, the engine sound can also be switched directly with the proportional channel #4. 14 BEIER-Electronic 28.07.
GB Sound module USM-RC Connection of the sound operation in analogue mode Connection of the motors In the analogous operation, 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 occurs parallel to the existing connections of the speed controllers which powers the motors.
GB Sound module USM-RC 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, additional sounds 9-12) are not available. To occupy the proportional channels #2 - #4 with several functions, these channels are split into the 5 areas "A, B, N, C and D ".
GB Sound module USM-RC Assignment of channel #4: Position Function short (0,5-1,0s) in position long (>2,5s) in position A additional sound 5 (#18) volume control on B additional sound 7 (#20) C additional sound 8 (#21) D additional sound 6 (#19) engine sound on/off The functions which are here described, do not have to be used all of them. It is only supposed to be represented in this overview, what with the channels #2 - #4 can be done.
GB Sound module USM-RC Stick simulation with switches To use all functions of the proportional channels #2 - #4 conveniently, you can simulate the different potentiometer positions of a stick, through a simple keystroke. If you press the key S1, a stick position is simulated for position A. Often the available sticks are already reserved by other functions, but the remote control has still other free channels. This schematic can be used for the further channels to activate the additional sounds.
GB Sound module USM-RC Loudspeaker You can connect every loudspeaker to the sound module USM-RC, which has an impedance of 8 - 32 Ω and was designed for the respective maximal power. The maximum power and the volume of the sound module, is depending very much from the height of the supply voltage and the loudspeaker impedance. The following table shows which maximum sine-wave power at different voltages and loudspeaker impedances can be reached.
GB Sound module USM-RC Volume control A volume control is possible by an external potentiometer (100kΩ). You connect this potentiometer to connector X3 (see wiring diagram, page 7). If no potentiometer is connected, always the maximum volume is spent. If the sound module is used in the digital operation, the volume can be controlled also by the remote control. The proportional channel #4 is used for that. To activate the volume adjustment, the stick must be brought for at least 2,5s in position A.
GB Sound module USM-RC Sounds All sounds are stored in the sound module with our software USM-RC SoundTeacher, in so called „slots". Generally we can say, you don’t have to occupy every slot with a sound. If you don’t want e.g. any starting-noise, let the slot #3 simply free. Here an overview, which sounds in which slots, can be stored: Slot #1 #2 #3 #4 #5 #6 #7 #8 #9 #10 #11 #12 #13 #14 #15 #16 #17 #18 #19 #20 #21 #22 #23 #24 #25 #26 #27 #28 #29 #30 #31 #32 #33 #34 #35 #36 #37 28.07.
GB Sound module USM-RC Engine sound (Slot #1 - #9) The engine sound consists of several single noises. Normally there is a turn on noise, idling noise, driving noise and turn off noise. This sound module offers also the possibility to imitate a driving noise under partial load, a reverse driving noise, a brake noise, a starting noise and a stopping noise. All engine sounds (therefore also the reverse driving and brake noise) play only when the engine sound is switched on.
GB Sound module USM-RC Brake noise (#9) The brake noise is played when the driving speed is strongly reduced. In the folder „USM-RC Sounds”, on the supplied CD-ROM, you will find some exemplary sounds for different vehicle types. In order to store a new sound on the sound module, simply start the program „USM-RC Sound-Teacher", open an *.usm project file that is in the respective folder and upload the new sound with the USB cable to the sound module.
GB Sound module USM-RC Additional sounds 1 - 16 (Slot #10 - #29) With the proportional channels and the switching-inputs, according to operation mode (digital or analogue) and number of motors, up to 16 different additional sounds can be played. To play an additional sound, it must be started with a start pulse. This happens either, if you activate the corresponding switching-input shortly or, in the digital operation, putting the stick into the corresponding position (A, B, C or D).
GB Sound module USM-RC Random sounds (Slot #30 - #37) Up to 8 random sounds can be played with the sound module USM-RC. The point of time of the sound playback, is determined then by a random generator. The time spans (min. /max.) can, for every sound separately, programmed by 1 - 250 seconds. In the same way it can be programmed for each of the 8 random sounds, under which conditions (idling/drive - engine sound on/off) the sound should plays. So you can define, e.g.
GB Sound module USM-RC Switching outputs The sound module has 7 outputs, which them for example lamps, LED, relays… can be switched. These 7 outputs are assigned with: Output #1 and output #2 (Multifunction outputs) These two outputs can be programmed by the USM-RC Sound-Teacher with different functions. These outputs can be related to one (or several) sound slots and switches always on, when the related slot is just playing.
GB Sound module USM-RC Output #6 (Indicator left) To switch the indicator on or off, the stick of proportional channel #2 must be put very shortly in position A. In the analogous operation the indicator is switched by the switching-input X1/9. Output #7 (Indicator right) To switch the indicator on or off, the stick of proportional channel #2 must be put very shortly in position D. In the analogous operation the indicator is switched by the switching-input X1/10.

A new window is opened, in which different settings can be done.. “Soundmodul-Konfiguration” Here is defined, whether the module should works in the digital or analogous operation mode (see page 5). Here is also defined, whether the model has 1 or 2 driving motors.
GB Sound module USM-RC “Zufallssounds” If you want to play random sounds with your sound module (see page 25), you can configure here, in which temporally distances the random sounds are supposed to be played. Times between 1 and 255 seconds are possible. Here is also configured under which conditions the random sounds should be activated. For example, whether the random sounds only should playing when the model stands and/or moves or whether the driving sound is on and/or off.
GB Sound module USM-RC Uploading sounds into the sound module !!! ATTENTION !!! If the sound module is only powered via the connected USB-cable, the 7 switching outputs may not be connected and/or may be switched on. If attention is not paid to this, the needed current for the connected loads is pulled out directly from the USB port.
GB Sound module USM-RC Firmware update Also the firmware (the internal software) of the sound module can be updated by the USM-RC Sound-Teacher With the menu Datei Æ Firmware aus dem Internet laden can be checked whether a new firmware (e.g. with new functions) for the USM-RC sound module is available. You can download these from our internet page to your hard disk. The firmware update is uploaded to the sound module by the USB cable. Connect the sound module with the USB-cable to your PC.
GB Sound module USM-RC Converting sound files If the sound files aren’t in the necessary format, they must be converted before they are able to be transferred into the sound module. Every arbitrary sound converter which offers the necessary functions can be used for this. There is a demo version of the software „GoldWave” on the supplied CD. You find the software in the folder „Goldwave".
GB Sound module USM-RC Record and edit new sounds with the PC There are some sample sounds on the supplied CD-ROM, with which you can make first attempts with the sound module. But sometimes you want to use your own sounds on your sound module.
