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.
General references to the wiring in the model:
Unfortunately the speed controllers and motors in the model are often strong
interference sources, which can disturb the electronic of the sound module
or the sound output (whistles, humming in the loudspeaker). Therefore all
motors should absolutely be suppressed!
It is also important to pay attention, to most possible „clean" wire routing.
You should use always short wires and don’t make 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.
