GB Sound module USM-RC

28.07.2008 BEIER-Electronic 3

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.

The sound output occurs on this module four channeled, so in addition to the driving

sound, 3 further additional-/random sounds simultaneously can be played.

The information of the driving speed (up to 75 steps!) can be taken from 1 to 2

motors (analogous operation), or 1 to 2 proportional channels (digital operation) of

the receiver are used for the speed information.

All sounds can be changed at any time on the sound module. For this purpose, only

a Windows PC with an USB port and our software "USM-RC Sound-Teacher" is

necessary. You can use this sound module for the most different kinds of models.

Since there is already an efficient audio amplifier on the board, only a loudspeaker

needs to be connected for the sound output.

At 7 switching outputs for example LEDs, lamps, relays can be connected, and

different lighting effects (light, stop light, indicators, hazard warning light, MG fire,

flickering-light and so forth) can be realized.

Safety notes

• Read this operating manual carefully and keep it for a future use well!

• The integrated circuits on the sound module are sensitive to electrostatic

charge. You may not touch therefore these components, before you don’t

have discharged yourself (e.g. through a grip onto a grounded device).

• To guarantee an interference-proof operation, the sound module should be

built in a suitable case.

• The sound module may be use only with those, in the technical data given

supply voltages.

• Always switch off power before connecting the module!

• For children under 14 years, the using of the sound module is not suitable.
