Dante HC

High Channel Count, High Capacity, High Performance
Audinate’s tradition of creating innovative and cutting-edge solutions continues, with the introduction of Dante HC™, the industry’s highest-capacity networked audio solution for professional AV systems. Dante HC supports up to 512 x 512 redundant bi-directional uncompressed audio channels on a single Xilinx™ FPGA. Dante HC expands Audinate’s broad portfolio of audio networking platforms, which OEMs can build upon to create cost effective AV products.

The Dante HC reference design is ideal for AV equipment products requiring high channel capacity, such as audio matrix routers, large format consoles, public address and evacuation systems and large scale DSPs.

Dante HC is a comprehensive reference design product that includes all the tools and resources required to rapidly integrate Dante into the AV manufacturer’s products, allowing high capacity networked products or Dante interface blades to be built. Applications include real-time streaming for broadcast, commercial installation, live sound, public address, intercoms and transportation communications deployments.

Scalability with Flexibility

Dante facilitates the rapid convergence of AV and IT, eliminating the limitations imposed by point-to-point cabling. Even digital point-to-point legacy audio signal distribution technologies such as AES3, TDIF, ADAT and MADI have disadvantages, in that they require separate wiring, increasing the cost of deployments. With Dante, audio is converted to digital audio over IP Ethernet packets, allowing audio signals to be software-routed over standard IP networks. Dante systems can easily scale from a simple pairing of a console to a computer, to large capacity networks running thousands of audio channels. One cable does it all. Dante does away with heavy, expensive analog or multicore cabling, replacing it with low-cost, readily available CAT5e, CAT6, or fiber optic cable for a simple, lightweight, and economical solution. Dante integrates media and control for your entire system over a single, standard IP network.

Simplified Signal Routing

High capacity does not mean high complexity. Audio routing and device configuration in Dante is made incredibly simple with Dante Controller, a free software application that automatically discovers all endpoints within seconds, and enables endpoint-to-endpoint channel connectivity with a single click. Because Dante uses logical routes instead of physical point-to-point connections, the network can be expanded and reconfigured at any time with just a few mouse clicks. Dante Controller is much more than just a configuration and routing matrix; it provides essential device status information and powerful real-time network monitoring, including device-level latency and clock stability stats, multicast bandwidth usage, and customized event logging, enabling you to quickly identify and resolve any potential network issues. You can also quickly and easily backup, restore, move, and reuse Dante network configurations using Presets, and edit Dante routing configurations offline.

Glitch-free Redundancy

Many large-scale deployments will also require a solution that is highly available. By leveraging Dante’s unique high-availability networking techniques, audio can be duplicated across physically separate primary and secondary networks. In the event of a connectivity problem on the primary network, endpoints will continue to receive audio via the secondary network, and will maintain play-out with no interruption and no glitches. This allows OEMS to build highly available high-capacity solutions for live sound or life-safety public announcement systems that must transport audio and messages with 100% integrity. Dante HC is the new heavyweight champion of the world-leading Dante range, delivering impressive power, functionality and flexibility in a compact design.
