AVNT I Audio
With this certificate, an AV technician will be able to:
– Understand the fundamental aspects of IP addressing
– Understand how an audio over IP source sends packets over an Ethernet network
– Use the right methodology to choose the products and create a basic audio over IP network
– Use the right methodology to setup a basic Dante Network
– Use the right network terminology
– Set a complete IP plan, and apply it over all the devices
– Understand the basic commands for connectivity test and troubleshooting
– Understand the challenges you can encounter on an audio over IP network
– Understand the limits of an audio over IP network
– Use the right methodology to create a diagram of its network
Profile: an AVNT I-A certified technician is able to design, set and configure a basic audio over IP network on its own.
He can use Dante, AES67 or AVB, and can troubleshoot the system in case of problem. Additionally, and if the technician already owns skills will an audio console, he’ll feel much more confortable when setting up or troubleshoting its audio over IP network.
The AVNT I-A certified technician will also be the perfect collaborator to assist an AVNT II technician, whom will be in charge of the main backbone.
Please find below the detailed program of this AVNT I-A module
Presentation of the module and the operating mode, and acquaintance with the learners.
• Assessment of learners’ expectations with regard to training.
• Presentation of an audio system over IP, its main components
• Why use Ethernet?
• Audio fundamentals (concepts): sample rate, resolution, latency / delay, clock, jitter (part 1)
• Wiring, throughput, distances (Part 1)
• Physical topologies
• The concept of hop
• Network equipment (unmanaged switch): specifications, selection criteria, other equipment (stage box), routers.
• Casting (Unicast, Multicast, Broadcast)
• PoE (part 1)
• Number systems: Binary, decimal and hexadecimal
• Static IP addressing
• Communication between two network devices
• Link testing tools (Ping)
• Link testing tools (scanning software)
• IP classes
• CIDR notation
• Dynamic IP addressing
• Zéroconf (Link local)
• Network digital audio fundamentals (part 2):
Sample rate: what you can do and what you cannot do
Resolution: what to know
Latency / delay: The parameters to be taken into account
Clock: network clock and media clock – PTP v1
Jitter: what to consider
• Presentation of the different products used to create a basic Yamaha digital audio network (Console, stagebox,).
• The concept of flow
• Dante patch via the console
• The devices supported by Yamaha (Online / Offline), Implementation methodology
• Creation of a basic Console – StageBox network
• The concept of redundancy
• Creation of a redundant network without switch
• Creation of a redundant network with A / B switch
• Creation of a kit of two consoles + a stagebox
• Presentation of the Dante protocol – Basic and advanced concepts
• Dante hardware & interfaces
• Dante Controller
• Bandwidth prediction
• Creation of a multicast stream
• Creation of a basic Dante network with PoE
• Dante Via
• Creation of a virtual Soundcheck
• Troubleshooting: the methodology
• Challenges :
• Quality of service: the concept, the advantages and the drawbacks, when to use it?
• IGMP Snooping: the concept, the advantages and the drawbacks, when to use it?
• Other audio protocols
• AES67, ST2110-30, RAVENNA: Interoperability, specificitions
• When to use PTPv2?
• The tools
• Creation of an AES67 stream from a Dante device
• AVB / Milan: The specifications
• Creation of a basic AVB network with Hive
• Dante> AVB conversion with a bridge
• Create a diagram, the basic rules
Practical exercise carried out by the learner independently:
– Creation of a redundant audio over IP network with console, switch, stagebox and interconnections with Dante equipments (interface, speakers and DVS), and conversion of AES67 or AVB streams. The learner will first have to create the diagram of the network, and will then have to implement it.
