The Digital Power Amplifier System interfaces with the AVAU controller in the Public Address System. The system consists of a powerful microcontroller based on ARM Cortex-M4. The function of the microcontroller is to receive digital data and command via Ethernet RS485/CAN/MVB port and commands from PC/external control system, program audio controls as per the commands and update the EEPROM. The microcontroller chip will be programmed to control all the digital processes of the system. The system interfaces with multiple buses like Ethernet LAN, RS485, CAN bus and MVB. These interfaces will be galvanic isolated. An audio from speech pair-2 input, to the system supports the existing Public Address/Passenger Information System.
