Description

The audio amplifier is suitable for the following modules:

Sound speed controller SFR-1 Double sound speed controller SFR-1-D Double sound speed controller SFR-1-HL Sound module USM-RC-2 Sound module USM-RC-3 Mini sound module MSM-1 Sound modules from other manufacturers

The digital (Class-D) amplifier PV-100W was specially developed for our sound modules and sound speed controllers in order to achieve significantly higher performance and thus higher volume of the sound output.

The PV-100W works with voltages of 7 - 30 V. However, a supply voltage below 12 V is generally not very useful, as higher output power can only be achieved at higher voltages.

The PV-100W can be powered by a battery that is already in the model. However, it is also possible to use a separate battery.

1 or 2 speakers with an impedance of 4 ohms each can be connected.

The speaker output of the sound module or sound speed controller is connected directly to the audio input of the amplifier. The audio input is galvanically isolated and no additional level converter or filter is necessary. However, a ferrite ring (included in delivery) must be installed in the cable between the sound module and the audio input.
