What do I need to equip my RC model with sound?

Sound Module
Of course, a sound module is required. We recommend the USM-RC-3.

If you have a "standard" RC remote control system (eg, a receiver in which you can plug in speed controller and servos), it is easy to connect the sound module. Here it does not matter whether the system is operating with 27 MHz, 40 MHz or 2.4 GHz.

The USM-RC-3 has 8 proportional inputs which are connected to the receiver.

The 1st prop channel (throttle channel) is used for the detection of speed, so that the sound module can play the engine sound at the correct speed. For a model with two drive motors, even the second prop channel of the sound module is required.

With the remaining 6 or 7 prop channels of the sound module, additional functions (eg, additional sounds, driving sound on / off, output for lights, servos, etc.) are controlled (see page 36 of the manual).

Speaker
To play the sound, a speaker is needed. At the USM-RC-3 a speaker with an impedance of 4 or 8 ohm can be connected.

The speaker which is used depends primarily on the space available in the model. Basically it can be said that the greater the speaker, the better the sound will be.

With a sound module and speakers you have the minimum requirement for a model with sound.
All other items are optional and are not necessarily required.

For great light effects, the USM-RC-3 has an extensive light unit. There are different option how to apply lights:
  • Ready to use lightning boards: For many models, different manufacturers already have suitable, fully assembled lighting boards that can be easily installed in the model. The matching series resistors are usually already on these boards. In this case only the cables have to be connected to the switching outputs of the USM-RC-3. To simplify the connection, we offer the AKL-8 terminal clamp. The USM-RC-3 has two slots, each with 8 outputs. We recommend to use two AKL-8, the first clamp for the front lights and the second for the rear lights.
  • Kraftwerk EasyBus light unit: The light connection becomes even easier if you use the EasyBus lighting boards from Kraftwerk. Via a bus system, the lighting boards are only connected to the EasyBus adapter, which then is plugged into slot X5/1 of the USM-RC-3.
  • Individual LEDs: You can also build the lighting yourself (with a bit more work, of course) with individual LEDs. It is important to mention, that the LEDs require suitable series resistors! These can be soldered to the LEDs, or you can use our terminal clamp AKL-8-W, which has plug-in resistors.
Additional useful accessories:
  • Data cable: Using the K-USB-2 data cable, settings and sounds can be changed without the annoying plugging in and out of the SD card (between the USM-RC-3 and the card reader on your PC). Also a live diagnosis e.g. for troubleshooting is possible with the data cable. The data cable is not absolutely necessary, but it makes working with the USM-RC-3 much easier and more comfortable.
  • Volume control poti: With the poti, the volume of the USM-RC-3 can be changed directly on the model. However, it is also possible to change the volume using the remote control or to set it permanently using the sound teacher.
  • Light module for trailer: A great option if you have a semi-trailer, trailer or road train is the infrared light module LM-IR-16-4 and bluetooth light module LM-BT-16-4 . With the modules it is possible to transmit the light outputs 1 - 16 of the USM-RC-3 wirelessly. With four additional servo outputs and one motor output, servos, motors or speed controllers can be connected and controlled easily, e.g. for supports or ramps.
