“I connect the auxiliary output of my console to the splitter input using a RCA to XLR cable and the signal does not reach my camera”

In a cable with one end in RCA and the other in XLR, we are using an unbalanced connection (RCA) at one end and balanced connection (XLR) at the other end. In order these connections can be adapted and the audio signal can be transmitted correctly from one end to the other, the cable configuration must be taken into account.

Making the connection of the RCA connector according to an unbalanced connector (the positive to the tip and the ground to the chassis) at the end with the balanced XLR connector, we follow what the AES14-1992 (R2009) standard tells us: make a bridge of union between pin 1 and 3.
