If the output power is still not enough for your application, it is possible to use a
speaker to RCA line level converter (high/low) mit galvanic separation (used in car
radios) and a small capacitor (10nF) at the input, in order to connect an additional
amplifier.
Volume control
A volume control is possible by an external potentiometer (100k
Ω
).
You connect this potentiometer to connector X7 (see wiring diagram, page 9).
If no potentiometer is connected, always the maximum volume is used, which is
configured in the Sound-Teacher (10-100%).
The volume can be also controlled by the remote control. The functions ““
and “Volume -“, must be configured in the Sound-Teacher e.g. to a proportional
channel or to a nautic switch.
General notes to the volume
Please also notice that the sound data you transfer to the sound module should have
an optimal modulation. For instance a common mistake is that the record of the
sound is far too quiet and therefore it can not be played properly.
In the Sound-Teacher you can easily adjust the volume of each sound (10-300%).
