Dante — Digital Audio Network Transport
Dante (Digital Audio Network Transport over Ethernet)
For full architecture and configuration details, see dante in the networking section.
Dante is the most widely adopted professional audio networking protocol, developed by Audinate. It carries uncompressed, multi-channel digital audio over standard Gigabit Ethernet with guaranteed low latency (typically 1ms), making it suitable for live sound, installed systems, broadcast, and recording. Dante handles clock synchronization via IEEE 1588 PTP and supports network redundancy — both critical for professional deployments where audio failure is unacceptable.
What Dante Does
Dante replaces analog and AES3 point-to-point connections with a single Ethernet network carrying all audio channels simultaneously. A Dante-enabled console, amplifier, DSP, or I/O box appears on the network as transmitters (outputs) and receivers (inputs). Any transmitter can be routed to any receiver using Dante Controller software, without running new physical cables.
A single CAT6 cable can carry hundreds of audio channels simultaneously in both directions. Dante devices discover each other automatically using mDNS/Bonjour on the local network.
Where Dante Appears in AV Systems
Dante is embedded in hardware from hundreds of manufacturers:
- Mixing consoles: Yamaha CL/QL/TF series, Allen & Heath dLive and Avantis, Shure MXA series
- DSP processors: QSC Q-SYS (native), Biamp Tesira, ClearOne Converge Pro 2, Shure IntelliMix P300
- Power amplifiers: Crown DCi-DA series, Lab.gruppen PLM, QSC PLD/CX-Qn series
- Stage boxes: Yamaha Rio, Allen & Heath AR series, Focusrite RedNet series
Dante and AES67
Dante devices can operate in AES67 mode, allowing them to exchange audio with non-Dante devices from other manufacturers that support AES67 (Ravenna, Livewire, Q-SYS). In AES67 mode, Dante sacrifices automatic discovery and routing convenience for interoperability. See dante-vs-aes67 for a full comparison.
Network Requirements
- Gigabit Ethernet — 100 Mbps switches are insufficient for systems with many channels
- VLAN separation — Dante traffic on a dedicated AV VLAN, isolated from general IT and BYOD. See vlan-configuration-for-av
- IGMP snooping — Required on all switches to handle multicast audio streams. Without it, multicast floods all ports. See multicast-and-igmp-snooping
- QoS — Dante uses DSCP 46 (EF) for audio; must be configured on all switches. See qos-for-audio
- PTP grandmaster — All Dante devices synchronize clocks via IEEE 1588 PTP. See time-sync-protocols
Dante Controller
Dante Controller is Audinate's free Windows/Mac software for routing and managing Dante networks. It displays all Dante devices, their available channels, current clock status, and routing assignments. All routing changes take effect in real time. Dante Controller is essential for commissioning and troubleshooting — it provides the only comprehensive view of the network's audio routing state.
Common Pitfalls
- Unmanaged switches — Dante requires managed switches with IGMP snooping and QoS. Using unmanaged consumer switches causes multicast flooding, clock instability, and audio dropouts.
- Mixed VLANs without proper routing — Dante devices on different VLANs cannot discover each other by default. mDNS does not cross VLAN boundaries. Use Dante Domain Manager (DDM) for multi-VLAN deployments.
- Clock master conflicts — Each Dante domain elects one PTP clock master. In systems mixing Dante and non-Dante devices, ensure the clock master is a stable, dedicated device rather than a laptop running Dante Virtual Soundcard.
- Sample rate mismatches — All Dante devices in a system must operate at the same sample rate (typically 48 kHz). Dante Controller displays mismatches in the routing matrix as routing failures.
- Dante Virtual Soundcard instability — DVS on a general-purpose laptop introduces clock instability and dropouts when the CPU is under load. DVS is for recording and monitoring, not mission-critical audio routing.
