Claim 0:
1. A power supply for a multi-channel amplifier, the power supply comprising:
a multi-phase power factor correction (PFC) circuit configured to boost input mains alternating current (AC) power to a final PFC output voltage, wherein the multi-phase PFC circuit comprises a first array of fault detection and protection devices, wherein a first set of fault detection and protection devices is coupled to a respective boost stage for each phase of the multi-phase PFC circuit;
a first interface to a system controller, wherein the system controller is configured to
receive first fault information from the first array of fault detection and protection devices, and
transmit the first fault information to components that are configured to provide failure compensation measures based on the first fault information; and

a first output combinatorial circuit configured to sum a first output voltage from each respective boost stage to produce the final PFC output voltage.
