Volume Control - beier USM-RC-2 Operating Manual

D Sound module USM-RC-2
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 (100kΩ).
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 "Volume +"
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%).
