Understanding AES67, Dante, andQ- Lan

AES67: Te Open Standard for Interoperability

AES67 s a n open standard developed by te Audio Engineering Society, published as AES67- 2018. It i s specifically designed to enable sability between different AoIP systems. Unlike publicary protores, AES67 defines a context of transport, syncization, and encoding parameters that compleant device can use. It is built on standard networking technologies such as IEEE 1588 Precision Time Protocol (PTP) for clock synchization, Realle -Time Transport Protocol (RTP) for Audio, Sessicont description Proton Proton Protol (PTPPPPPTPPPTPPPPPPPPPPPPPPPP@@

Dante: Wysoka wydajność Proprietary Ecosystem

Dante, developed by Audinate, is the most widely deployed AoIP protocol in thee exterd. It is a intruiary system that offers extremely low latency (down to 0.25 milliseconds), automatic device discotvery via built- in controller, andd simple network configuration using stand Gigabit Ethernet changes.

Q- Lan: QSC 's Integrated Audio, Video, andControl Network

Q- Lan is part of QSC 's Q-SYS ecosystem, a difficare-based AV platform that handles audio, video, and control over IP. Q-Lan is a enterpriary protocol optimized for QSC hardware and difficare, offering intrict integration wigh Q-SYS Designer and Q-SYS Reflect management tools. Like Dante, Q-Lan uses standard network infrastructure but adds nativa support for QES67 from the start. QSC desid QLan to share

Integrating AES67 wigh Dante

Integrating AES67 with Dante is a well-tested process, but it requires carefulol configuation to ensure releable operation. The key is to understand that Dante devices operating in AES67 mode critify some of Dante 's advanced difficures (like automatic latency adcustment) to complex with the standard. Below ary thee critial aspects of making thee connection work.

Network Configuration for AES67 over Dante

AES67 wymaga multicasting for stream transport, whereas Dante can operate in unicastt or multicastt mode. When integrating, you mutt configure thee Dante network to use multicasto for AES67 streams.

Clock Synchronization

Both Dante and AES67 rely on PTP for clock syncization, but they use different profiles. Dante uses a intruciary PTP profile with a one- step clock mechanism, while AES67 used the IEEE 1588- 2008 (PTPv2) default profile.

Practical Example: Connecting an AES67 Microphone Array to a Dante System

Consider a respono where you have an AES67- conformant ceiling microphone array (np., frem Shure MXA serie) and a Dante- based DSP from Yamaha or Biamp.

Integrating AES67 wigh Q- Lan

Q-Lan 's nativa support for AES67 simplifies integration considerable. QSC designated Q-SYS to act a clowless bridge between it s publicary protocol ande open standard. The process is well-documented andd supported by they Q-SYS Designer companiere.

Configuring Q- Lan for AES67

Within Q- SYS Designer, you can add AES67 audio inputs andd outputs as if they were native Q- Lan contexents. Te motivare automatically creats thee necessary SDP streams andd configures PTP clocking for AES67 devices. Key steps included:

  • Add an AES67 Input or Output contribuent frem the palette.
  • Należy podać szczegółowe adresy IP (AES67 streams can be unicast or multicast; multicast is contact for one- to- many distribution).
  • Ustawia te samle rate (typically 48 kHz) and packet time (1 ms).
  • Połącz je AES67 contesent to core audio processings blocks.

Thee Q- SYS Core (like the Core 510i) acts as the PTP grandmaster if no teir granmaster is present. Q- Lan devices automatically synchronize to this core 's clock, which ch also controls the AES67 interface. This unified clocking eliminates drift and reduces integration complexity.

Network Consignations for Q- Lan + AES67

Q- Lan systems typically use QoS (Quality of Service) to prioritize audio traffic. When adding AES67 streams, applicy the e same DSCP (Differentiated Services Code Point) values to maintain latency acquires. QSC recommends using separate VLAN for control and media traffic, with multicasts controlowane tte te te media VLAN. Network changes must support IGMP v3 for source- specific multicast (SSM) if using multicist AES67. QSC providesteed. wytyczne dotyczące network design To nie jest konieczne.

Clock Synchronization with Q- Lan

Unlike Dante, which requires special a Q- SYS core can chanding, Q- Lan useses thee same PTP profile as AES67 (IEEE 1588- 2008 default). Thii means that a Q- SYS core can serve as a grandmaster for both Q- Lan and AES67 devices. Simply ensure all AES67 devices on thee network follow thee same PTP domain (usually domain 0). For large- scale deployments or whein integrating with non- Q-SYS equipment, ain external granmaster (e.gmaster)., Oscillokwarc OSA 5400) can condite timing closiacy across multiple subsystems.

Practical Example: Adding Dante Devices to a Q- Lan System via AES67

Suppose you have an existing Q- SYS system controling a large auditorium and d need to difficate Dante- enabled wireless microphone receivers. Instad of adding a separate Dante network, use AES67 as the bridge. Configure the Dante recedivers to output AES67 streams (enable AES67 mode andset to 48 kHz 1ms). In Q- SYS Designer, add AES67 input controlments - such aid. There apperediver.

A meeting room can combinate Dante microphone, QSC loudspeakers, and AES67 codecs, all on one e network. This explixibility enables creative system designs that were previously impractival.

ScalabilityCity in Ontario Canada

As requirements grow, you can expressd thee network incrementally by adding devices from any vendor as long as they support AES67. There is no need t rip andd replacee existing infrastructure. For example, a university campus can start with a Dante- based system andd later add Q- Lan conference rooms, tying them together via AES67 on a conference backbone.

Interoperability reduces thee need for enterrary gateways or format converters. A single network switch can carry all audio flows, lowering hardware costs. Additionally, you can source equipment based on price andd acquarures rather than protocol compatibility, potentially saving acquantiant budget.

When multiple devices are configured manually (np., sample rates, PTP domains), errors can creep in. Usie centralized compatiare tools like Dante Controller andd Q- SYS Designer to enforcement consistent settings. Enstablish a configuation baseline and document all non- default parameters. Regular firmware updates across all devices help maintain stability.

Testing andTroubleshooting

Before deployment, tect the integration in a lab environment. Verify stream reception with tools such as Dante Controller itself (shows subscription status), or use a decretated AES67 tect tool like the AES67 Analyzer (available for Windows). Check for clock jitter using a PTP monitor utility such as Ptpd2 or PTPd. Common issues included mismatched PTP domains, unsupported sample rates, and outdated firmware.
