More than 2000 devices from 300+ companies are Dante-compliant and products are available across many market sectors from Corporate, Education, Broadcast, Live performance and of course Home AV.
Dante is a proprietary technology with hardware implementation that is licensed to manufacturers to implement their own products or implement into existing products. Launched in 2006 by Audinate, Dante is not focused on one market sector, so this helps to broaden the adoption within all audio markets. We won't be covering these here as we have enough to cover already. It's not an AoIP technology rather a transport over Ethernet. It provides a point-to-point connection between the controller and speakers. There are other options, but these are typically manufacturer-specific and are closed protocols for that system.Ī good example is SpeakerLink from Meridians 271 Digital theater Controller. There are a number of different standards available on the market but we are going to talk about the main 4 you will come across. What options are available on the market? They are supported in most network environments. To minimize potential negative effects from rivaling bandwidth requirements of other shared services on the network, effective Quality of Service mechanisms like DiffServ and VLAN are available. IP as a transport protocol can operate on many network infrastructures and virtually any existing network equipment it is not bound to a specific technology or topology. The IP protocol is based on and works with a number of widely deployed standards. “Dumb” or unmanaged switches are acceptable if it’s only audio traffic that is involved and is limited to a single switch. The technologies we are talking about today are including the Network Layer 3 (refer to OSI Model) where routers, compatible network switches and equipment are often but not always required. No router is required, it's just a point-to-point audio network over Ethernet. Both protocols are classed as Audio over Ethernet. Probably some of you have installed and set up some on these networks like CobraNet or EtherSound. This is not a new idea, as the first AoIP networks were commercially available in the 90’s.
This is made via a single cable such as Cat5e or Cat6 or higher data rate cables like fibre. We hosted a webinar as an Introduction to AoIP that you might find useful before reading this document or to learn more following this introduction.ĪoIP is a network protocol(s) that allows you to send high-quality digital audio signals over the IP network. Be warned if you are not comfortable with networking this might feel quite intimidating. We will then discuss their place in Home Theater applications. We will discuss the pros and cons of the technology and give you an overview of the different technologies available to you from Dante, Ravenna, AVB and the convergent standard AES67. In this blog post, we aim to address the growing requirement for Audio over IP in Home theater applications.
