1. A power-over-Ethernet (PoE) powered multichannel streaming audio amplifier, comprising:
a plurality of Ethernet ports, each Ethernet port of the plurality of Ethernet ports configured to be coupled to an Ethernet cable, each of the plurality of Ethernet ports capable of receiving power and audio data transmitted via the Ethernet cables;
power supply circuitry, connected to the Ethernet ports and configured to combine and manage the power received at the Ethernet ports, wherein the power supply circuitry comprises a plurality of PoE controllers, each PoE controller of the plurality of PoE controllers being coupled to one of the Ethernet cables, and each of the PoE controllers configured to:
automatically identify an available power level corresponding to its coupled Ethernet cable, and
recover power from its coupled Ethernet cable; and
a microprocessor subsystem, powered by the power supply circuitry and configured to receive and process the audio data to generate output audio signals.
