We have seen a significant evolution in professional audio systems over the past few years. What once required extensive analogue cabling and complex physical connections can now be achieved through network-based audio solutions. The demand for flexible, scalable and efficient audio distribution continues to grow as
venues adopt more sophisticated AV systems. This has led to the adoption of networked audio.
What Is Networked Audio?
Traditional audio systems rely on physical connections between individual components. This can be seen in the way microphones connect to mixers, mixers connect to processors or amplifiers, and amplifiers drive loudspeakers. Instead of requiring a dedicated audio cable for every connection, networked audio allows digital audio signals to travel between compatible devices over an IP network. This is commonly known as Audio over IP or AoIP. For example, in a corporate office with multiple meeting rooms, compatible microphones, mixers, processors and loudspeakers can exchange audio through the network. Audio can be routed to different destinations without requiring technicians to reconfigure the physical cabling each time. This approach reduces the complexity of cables and makes it easier to modify an installation as requirements change.
What Is Dante & How Does It Work?
Dante is an audio networking technology that allows compatible devices to exchange digital audio using standard Ethernet networks. Rather than connecting every audio source directly to its destination, devices communicate through a network, with audio connections configured using software. For example, a digital mixer can send audio to a compatible processor or amplifier through the network. These connections can be configured using Dante Controller, a software application that allows users to discover devices and manage audio routing.
Dante also supports precise clock synchronisation, helping connected devices maintain accurate timing, which is especially important in professional environments where audio signals from multiple sources need to remain aligned.
Another advantage is its suitability for applications where sound quality and timing are of utmost importance by its ability to transmit uncompressed digital audio with low latency.
However, it is important to remember that Dante does not eliminate every physical audio connection. But rather, it changes how compatible devices exchange audio, while the overall system may still include analogue connections, conventional amplifiers and other equipment.
Why Is Dante Important In Professional AV?
Dante addresses several important issues.
1. Simplified Cabling & Installation:
In traditional installations, individual audio connections often require separate cables, and in larger venues, this can lead to extensive cable runs and complicated routing. Dante allows multiple audio channels to travel over Ethernet infrastructure, which reduces dependence on dedicated point to point audio connections.
2. Flexible Audio Routing:
Traditional audio systems usually follow fixed signal paths, and changing these connections sometimes can require physical rewiring. But with Dante, compatible devices can establish audio connections through a software. For example, a university can route audio from a central source to different lecture halls according to their individual requirements.
3. Scalability:
As organisations grow, AV requirements can frequently change. A Dante network can accommodate additional compatible devices if the network has sufficient capacity and is designed to support the expansion, eliminating the need to rebuild the entire system.
4. Centralised Management:
Managing equipment across multiple rooms can be challenging. Networked audio allows technicians to discover compatible devices, configure audio routing and investigate connection issues through software. Tools such as Dante Controller make it easier to manage signal paths without tracing every physical audio connection individually.
Professional Audio Equipment in a Dante-Based System
If you are exploring Dante-enabled audio equipment, here are some interesting ones we have picked out:
1. Audio-Technica ATSP-30:
The Audio-Technica ATSP-30, a network ceiling speaker, is designed for small to medium-sized meeting environments. The ATSP-30DP model supports Dante connectivity, allowing it to receive digital audio over an Ethernet network. Its two-way coaxial speaker design and wide coverage angle help deliver clear audio for speech, multimedia presentations and background music. In a networked meeting room, compatible audio equipment sends signals to the speaker system without requiring a separate analogue audio connection for every signal path.
2. Renkus-Heinz ICLX Series:
The Renkus-Heinz IC Live X Series uses digitally steerable line-array technology to help direct sound towards the intended audience. This can improve speech intelligibility in acoustically challenging spaces. Some models in this series support Dante. This allows for integration with other Dante enabled equipment, such as digital mixers and processors.
3. AtlasIED Amplifiers:
AtlasIED offers a range of professional amplifiers, including selected models with Dante network audio capabilities. For example, certain configurations in its DPA series support optional Dante connectivity.
4. MC2 Audio Delta Series DSP:
The MC2 Audio Delta Series combines amplification and digital signal processing in some models. The Delta DSP100, for example, supports Dante networking and provides processing capabilities that include FIR filtering.
What To Consider When Designing A Dante Network?
1. Device Compatibility:
Your audio equipment must support the required Dante functionality, either natively or through a compatible interface.
2. Network Infrastructure:
Ethernet switches, cabling and network configuration must support the number of devices and audio channels involved. Larger installations may require additional network planning to manage traffic and maintain reliability.
3. Latency & Synchronisation:
In live performance environments where audio timing is critical, the latency and synchronisation of your audio equipment matters more than you think.
4. Future Expansion:
Planning for additional devices, audio zones and network capacity can make upgrades easier and help the system accommodate your changing needs.
As professional AV systems become more connected, networked audio is making it easier to manage and expand audio setups. Technologies like Dante give AV professionals more flexibility in how audio moves across a space. Understanding how these systems work can help you make better decisions when planning an audio setup, both for your current needs and for future expansion.
