Digital audio networking systems that transmit and receive up to 64 audio channels over a single Ethernet cable, and more recently, digital wireless microphone systems.
These solutions allow audio inputs and outputs from enabled audio gear for instance, a wireless microphone system or mixer to be routed using a user's existing Mac or PC when loaded with the necessary software.
All inputs and outputs are carried as digital data running on lightweight, inexpensive Cat-5 cabling. An emerging technology to the uninitiated, digital audio distribution has proven reliable and road-worthy in applications ranging from sound reinforcement at the G8 Summit and the Sydney Opera House to recording applications at a member church in Vancouver, Washington.
While Australia-based Audinate's Dante is one of several competing protocols for communicating multiple audio channels over standard Ethernet and IP networks, it has led the industry in media attention, awards and licensing agreements with an impressive list of partners. In this post, we'll address a few of the basics, so that the next time Dante comes up in conversation, you won't be thinking of the Middle Ages poet who wrote the Divine Comedy.
We'll also share the potential of network-based AV protocols, filtered through the real world experience of Jonathan Sage who is the Senior Audio Engineer for Boston College and uses Dante the way you might use an audio snake.#105 - Audinate AVIO Dante Audio Adapter: First Look & Review
But more about that in a minute. Audio signals between Dante-enabled devices are routed using Dante Controller software. This software, available from Audinate, can be downloaded to a customer's Mac or PC and sets up the routing. This specific set of communication rules is called a protocol. Most of us are familiar with VoIP — the Voice Over Internet Protocol that transformed your land line - if you still have one - into digital phone service.
In an analog AV implementation, the logical and physical connections are the same - most connections are point-to-point and individual cables represent each channel. Copper cables are needed to for each individual signal path.
In Dante, the physical connecting point is irrelevant: as long as all the devices are connected to the same network, audio signals can be made available anywhere and everywhere.
Patching and routing are configured in software and not over physical wired links. Depending on the application, Dante allows up to bi-directional channels of audio to be sent and distributed over an Ethernet network, using CAT-5e cable or CAT-6 cable. For example:. Devices that are Dante-enabled like Shure's ULXD4Q wireless system utilize Dante Controller, Audinate software that provides a graphical interface for set up, routing and device monitoring.
It is designed to run on a customer's existing PC or Mac. Digital media distribution reduces set-up time, plus it eliminates the need for miles of increasingly expensive copper wiring.We're using cookies to improve your experience.

For the majority of systems, setup will be extremely straightforward. The following guide details exactly what to do with your managed switch when setting up the network.
Whether you're new to networking or a seasoned IT professional, the information below will be easy to implement. The Dante network requires the use of at least one Gigabit Ethernet switch. In larger installations multiple switches will be needed. For many networks an unmanaged switc will function without issue, however for the greatest flexibility — particularly as your network grows — we highly recommend the use of a managed switch. Unlike other networked audio systems, Dante works with standard, off-the-shelf Ethernet hardware, which is commonly available and needn't be expensive.
There are many switches available with varying features, number of ports and in various sizes. To set up the managed switch, the following DSCP values should be given the priority shown in the table. Please refer to the user guide of your managed switch for instructions on how to set DSCP packet priority values. This may be under a section called QoS or Quality of Service. The simplest way to configure a switch is to access it from you web browser. Start your web browser, and enter the IP address of the switch.
By default, the address of the switch is set to You should set the IP address of the computer beforehand to You should set the IP address beforehand to Note that this switch uses a scale of where 4 is highest priority and 1 is lowest. Set the priorities properly by clicking on the drop down menu and selecting the corresponding numbers. Next, click apply.
There is one final step — click save at the top right of the screen and on the following page, ensure that Running Configuration and Startup Configuration are selected. After clicking OK, reboot the switch. Accept Cookies. Toggle navigation. Search Search. Home Configuring a switch for Dante. Configuring a switch for Dante.Since its introduction in Dante has become the most popular AoIP technology.
It operates on Layer 3. Dante can use meg networks with QoSthough the channel count is restricted to 32 each way.
Configuring a switch for Dante
On a modern Gigabit switch channel counts of up to each way are supported as are sample rates of up to kHz. While Dante Via offers the possibility of software only Dante networks, to get the lowest latency performance Dante uses proprietary hardware. I think of this as being like graphics processing.
The standardised network interface in all Dante equipped hardware is what gives the predictable performance. In terms of network performance Dante uses best-effort delivery using quality of service QoS to prioritise clock and audio data on mixed-use networks.
There are currently over Dante licensed manufacturers. The current products supplied to manufacturers by Audinate are:. The latency figures for Dante depend on how you are accessing the network. For low latency performance using hardware nodes round trip latency is around 3ms For a computer running Dante Virtual Sound Card latency is much higher at around 10ms Dante Via has a similar network transmit latency of around 10ms but auxiliary signal paths such as USB audio devices will introduce further latency on top of this figure.
Because a Dante network is a network of proprietary devices all produced by a single company, it just works. It's very similar to the compatibility advantages of using exclusively Apple hardware in that all hardware is a known quantity. It certainly is doing well. The survey conducted by RH Consulting, which we recently invited Pro Tools Expert readers to participate in, shows clear evidence that Dante has assumed a dominant position in the market.
It has overtaken the older generation of networked audio products and of the current generation, its proprietary, layer 3 model has meant it is deployable across currently installed networks and it is relatively straightforward and, crucially, quick to develop and bring products to market.
Because of this it is owned by a company who want it to do well, and offer support to manufacturers wanting to use their product. This support is part of the cost of implementing Dante but it supports manufacturers in supporting their customers and this offers direct access to live market feedback for product refinement and development. The short term for Dante looks very positive as it offers ease of use and an excellent user experience.
As for the long term - well who knows? Audinate Hardware While Dante Via offers the possibility of software only Dante networks, to get the lowest latency performance Dante uses proprietary hardware. Not all have done so yet, including Focusrite. May 8, Jul 6, May 6, Individually route audio and video using familiar Dante Controller software, with no need for breakouts or matrix switches.

Featured Dante-Enabled Products. Full Catalog.Dante is a combination of software, hardware, and network protocols that delivers uncompressedmulti-channel, low-latency digital audio over a standard Ethernet network using Layer 3 IP packets.
Dante is an acronym for digital audio network through Ethernet. Like most other audio over Ethernet technologies, Dante is primarily for professional, commercial applications. Most often, it is used in applications where a large number of audio channels must be transmitted over relatively long distances or to multiple locations.
Digital audio provides several advantages over traditional analog audio distribution. Audio transmitted over analog cables can be adversely affected by signal degradation due to electromagnetic interferencehigh-frequency attenuationand voltage drop over long cable runs.
Thanks to digital multiplexingthe cabling requirements for digital audio distribution are almost always reduced when compared to analog audio. Dante also provides specific advantages over first-generation audio over Ethernet technologies, such as CobraNet and EtherSound.
Technological advancements include native gigabit support,  higher channel count, lower latency, and automatic configuration. There, with the help of government funding, the team spent three years developing the foundations of Dante.
