Connecting Yamaha Dante devices with AES67

Connecting Yamaha Dante devices

with other AES67 devices

Introduction

AES67 is a published standard which defines interoperability guidelines for high-

performance professional digital IP networking. AES67 provides the means for exchanging

audio streams between areas with different networking solutions or technologies already in

place, such as Dante, Ravenna, Q-LAN, Livewire, and WheatNet.

Yamaha also has started to successively update Dante products to support the AES67

standard beginning with the CL/QL series consoles and R series I/O racks. However,

please understand that AES67 is a transport option as part of Dante but will not be a

replacement of Dante. This is because Dante is a complete audio networking solution,

including control & monitoring software, network redundancy, and automatic device

discovery, while AES67 has limited functionality to achieve wider interoperability as

described below.

This document describes general instructions to connect Yamaha Dante devices with 3rd-

party non-Dante AES67 devices. For details on the 3rd-party device setup, please refer to

the documents each manufacturer provides as well.

Connecting Yamaha Dante devices with AES67 Connecting Yamaha Dante devices with other AES67 devices Introduction AES67 is a published standard which defines interoperability guidelines for highperformance professional digital IP networking.

Connecting Yamaha Dante devices with AES67 Feature Summary Dante Controller v3.6.2.4 and later supports the AES67-enabled Dante devices, but as of January 2017, the following requirements and limitations are applied to the use of AES67 with Dante.  SAP (Session Announcement Protocol) must be supported. This is one of four device discovery methods referenced in the AES67 standard. Check if the transmitting non-Dante AES67 device supports SAP.
PAGE 3
Connecting Yamaha Dante devices with AES67  Do not change the TX multicast address prefix (default 239.69).  Do not change the bit depth (default 24 bit) from Dante Controller or the console after enabling the AES67 mode. Rebooting the device or Dante module with the change could reset the multicast addresses if using a different multicast address prefix other than default 239.69, which would cause audio interruption.

Connecting Yamaha Dante devices with AES67 2. Execute “Clear Config” to initialize the Dante module for avoiding known issues. 3. Enable the AES67 mode. Reboot will be needed if the AES67 mode was disabled. Only devices that intend to transmit or receive AES67 flows need to have AES67 mode enabled. It is also possible to communicate between AES67-enabled Dante devices and standard (AES67-disabled) Dante devices at the same time. 4.

Connecting Yamaha Dante devices with AES67 Configuring the non-Dante devices 1. Make sure the non-Dante devices support SAP for automatic device discovery by Dante Controller. 2. Configure them in AES67 mode, though the methods may be different for each device. For details, please follow the instructions provided by each manufacturer. Make sure to specify the same multicast network address prefix that you specified for the Dante devices. 3.

Connecting Yamaha Dante devices with AES67 2. Make the input patches from the non-Dante AES67 devices as usual. Click the channel intersections in the grid, or drag and drop in the Device View Receive window. Dante Controller cannot make any patch to the non-Dante AES67 devices, because only the multicast audio flows coming from non-Dante AES67 devices can be found by Dante Controller, not the devices themselves.
PAGE 7
Connecting Yamaha Dante devices with AES67  Many non-Dante AES67 devices support PTP v2 only PTP v1 and v2 are not inter-compatible. One AES67-enabled Dante device will act as the boundary clock between PTP v1 and v2, bridging the two clock domains (i.e. Dante and the other). Dante and PTP v2 use different methods for electing the Master device. the two in combination, care needs to be taken.

Connecting Yamaha Dante devices with AES67 3) One AES67-enabled Dante device will automatically be selected as the Boundary clock, becoming the Dante Master. C. An external word clock source is used, connected to a Dante device. 1) Enable “Sync to External” and “Preferred Master” for the Dante device which is connected to the external clock. 2) Enable “Preferred Master” for the AES67-enabled Dante device which should be the Boundary clock and the PTP v2 Master.
