Introduction
The sound module USM-RC-2 was developed for the RC model construction in order
to equip models, with an as realistic as possible, speed-dependent (e.g. engine
sound). Additional turn on-, turn off-, starting-, stopping-, idling-, braking- and driving
backward sounds can be played, too. To make the backround noise perfect, in
addition to the engine sound, up to 30 additional sounds can be played. In addition 8
easy configurable random sounds are possible as well.
The driving speed of the model, is either been taken from 1 or 2 motors (analogue-
and mix mode), or 1 or 2 proportional channels (digital mode) of the receiver are
used for the speed information.
The sounds are stored on a micro-SD-card and can be changed at any time. For this
purpose, just a Windows PC with SD-cardreader and our software "USM-RC-2
Sound-Teacher" is needed. Therefore you can use this sound module for a variety of
models and can customize it to your own imaginations.
There is already a powerful double amplifier (2x20W) onboard, so you only need to
connect 1 or 2 speakers for the sound playback. An additional amplifier is no more
needed.
In addition there are up to 12 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.
Any number of switching outputs can be divided into 2 output groups. Any sequence
functions for these 2 groups can be programmed (for example moving lights, rotating
lights, beacon lights for airplanes).

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-2
Sound-Teacher. (see page 56).
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 (for example 35MHz, 40MHz or 2,4GHz). 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 or 3
additional proportional channels (and the 4 switching inputs) it is possible to control
different functions of the sound module (see page 57).
Analogue mode:
The analogue mode is used, if you don’t have „standard” RC equipment, that means
your receiver does not use standard proportional channels (1,0-2,0ms signals).
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 4 or 6 additional
sounds with the switching inputs.
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.
The mix mode is used, if the speed controller has special functions such as cruise
control and that’s why the controlling of the drive motor is different.
