The connection between pin 8 and the shield of the RJ45 connector to GND of the
module is made via the internal jumper JP1. If the installation requires it due to noise
caused by ground loops, you can separate this connection by changing the position of
jumper JP1 as shown in figure 13 on the following page.

RSAP-F2 module music program audio input
The program input uses an 8-pin RJ45 connector. It is a NON-balanced input with a sensitivity of 0dB (775 mV RMS). For connection
use FTP CAT5e or higher cable.
The signal applied to this input attacks the corresponding amplifier and is output through the SPEAKERS OUTPUT.
Activating the priority contact or activating the STANDBY contact cuts the audio from this input.
