    The scope of this document will start to focus on the general design choices which are made during the design phase of the project in combination with the corresponding implementations in hard- and software. Only the current status of the AURON Broadcast mixer will be discussed, no future features. 2.2.1...

  • Page 6: Design Overview

    3 Design Overview 3.1 Background Information The AURON, offers a true analogue signal path with flexible digital control. The console uses a split unit topology, a Master Unit connects to one or multiple 10 FADER units. The AURON features a 7” HD touch display for metering and system control with K-ALPS or Motor faders and optional modules for DANTE AoIP, Dual Telco cards, USB Audio insert card and BT cards for wireless connection to phones.

  • Page 7: System Architecture

    4 System Architecture 4.1 Overview The AURON system consists of one MSTR UNIT (master section) and one or more FDR units (10 channel sections). For a minimal system a master and one 10 channel fader unit is needed. If more than 10 modules is desired, additional FDR units can be daisy chained in the system as can be seen below: In the image below, a minimal system comprising 10 faders and a master section is depicted.

  • Page 8: Hardware Architecture

    To control 10 channel boards, five Auron-4 control boards are required. Additionally, an Auron-5 base board and an Auron-6 power supply are necessary to provide power to all the internal PCBs. These PCBs are interconnected using one or more interfaces, which will be explained in greater detail later in this manual.

  • Page 10 4.2.1.1 AURON-1 Channel Board Mic/Line The AURON-1 is an analog input channel board mainly used for connecting a microphone. On the PCB there are several digitally controlled analog switches (DCAS) which controls the analog audio path. Potentiometer controls: The potentiometers on the PCB have the following functions from top to bottom: GAIN, EQ-high, EQ-mid, EQ-low, AUX-send.
  • Page 11 The connector layout will be the same as the AURON-1 Channel Board Mic. The RJ45 will be a stereo- balanced input (compatible with AXUM patch panels). The XLR is a balanced mono input, GPO is off course available, and finally the CF/INS Jack has a to-be-determined function.

  • Page 17: Software Architecture

    4.3.2 Embedded Software (Firmware) The entire system contains of four different node types, auron-4, 5, 14, 16, each with a Microchip SAM E51 microcontroller on board. These controllers are interconnected by the CAN-FD bus. Each node has its own application code and they share a common bootloader which is used for updating firmware via CAN bus.
  • Page 18 4.3.2.3 Auron-address The Auron address process is responsible for providing a valid node ID. This node ID is stored in the internal EEPROM (non-volatile memory). To obtain a unique node ID , the node sends an identification message every second, this happens from the bootloader.
