2 Introduction CTO & Founder, Audinate We make Dante audio networking Elec Eng / Computer Science background Amateur musician, audio technology geek A networking guy in the audio world

3 Agenda Network & IT The Basics The Dante Toolbox Demonstration Hands on play / discussion

4 The Dante Toolbox April,

5 Outline Background What is Dante? Inside the toolbox

6 Background

7 Background Dante began as an R&D Project in 2004 NICTA government R&D lab Initial technology development Audinate founded in 2006 Spinout from NICTA First product: Dolby Lake Processor Offices Sydney, Australia; Portland, USA; Brighton, UK; Networking people IP networking, zeroconf, clock sync, QoS,

8 Audinate revolutionizes AV systems to enable our customers to thrive in a networked world

9 Audinate recognized as one of the fastest growing technology companies

10 160 Dante: The market leader with over 200 OEMs and growing Jan- 10 Jan- 11 Jan- 12 Jan- 13 Jan /2012 8/2013 2/2014

11 Dante is the most interoperable solution

12 What is Dante?

13 Dante is a complete solution toolkit For manufacturers Embedding Dante into their equipment Hardware, Software, Documentation, For users Reliable, interoperable networking between manufacturers Dante Virtual Soundcard Dante for PC/Mac computers Dante Controller Manage & monitor your network Plug and Play discovery One click routing Network health and monitoring

14 Dante Benefits Easy to Set Up Plug and play automatic discovery and simple signal routing No special skills required to set up audio networking Flexible Can support up to 512 bi- directional audio channels per Gb switch Supports a single integrated network for audio, video, control and monitoring Improved Audio Quality Doesn t suffer from hum, ground loops, degradation with long cable runs Accurate clocks synchronized to ±1μs Nearly imperceptible latency Cost Effective No need for expensive copper analog cable Uses widely available, economical CAT- 5e and CAT- 6 cable Leverages existing network components, PCs or Macs

15 Dante speaks the IT managers language Manage Addressing : DHCP Device Discovery: mdns User Friendly names: DNS- SD Quality of Service: Diffserv Unicast and multicast transport Efficient, VLANs not required Multicast management: IGMP Snooping No special switches are required IT managers may used their preferred switches and management tools

16 Dante is easy to use It seems pretty much idiot- proof. The whole networking thing was really easy to set up, because it auto- seeks, so you re not going through network protocols to make the computers talk to each other. It just works. It finds itself, it finds all its buddies, and it just goes. Device discovery User editable names One-click routing
