To complete the lifeline interconnection follow the procedure below:
1. The 6‑pole cable and connector for the amplifier are delivered with the amplifier. For
lifeline assembly instructions, refer to the following sections: Lifeline, page 71 and/or
Lifeline, page 87.
2. The 6‑pole connector (C) for the multifunction power supply is delivered with the power
supply.
3. Mount the connector (C) to the cable, following the same wire order as for the amplifier
side, the cable should be reversible.
4. Insert the connector (C) into the lifeline socket of the multifunction power supply, using
the socket next to the 48V outputs that go to the same amplifier.
Notice!
Each pair of 48V outputs A/B and the lifeline next to it belong to each other and are always
connected to the same amplifier. Keep the cables together to avoid errors that could result in
no sound in case of emergencies.
