The 24 V is required on the digital audio matrix board with DC 24 V power. It is
connected to the power supply via the 'PS-24V' connector. An earth connection to
the cabinet is required for a proper work of the digital audio matrix board. The
power supply reports a general fault status and an AC fault via the 'PS-Fault'
connector. These connectors are located in the inputs/outputs area on the lower
left corner of the board. All connections are pre-assembled.
