Dante Setup

The HOLOPHONIX processor handles 256 Dante® channels (128 in x 128 out) with up to a 96 kHz resolution. It is equipped with both a Primary (P) and a Secondary (S) port, for redundant connections ensuring a maximal reliability.

Connect the Dante® Primary and Secondary ports on your Dante® network’s primary switch and secondary switch, respectively. Use Gigabit Ethernet network switches, optimized and setup for Dante®.

note

Download and install the Dante® Controller software on an external computer (macOS® or Windows®) to configure the Dante® parameters of your HOLOPHONIX Processor, and assign the receive (Rx) and transmit (Tx) channels to your audio system.

important

Always follow Audinate®'s recommendations to set up your Dante® system. www.audinate.com

The configuration of the Dante® card must be performed on an external computer, connected to the Dante® network, with Dante® Controller software by Audinate®. To access the settings of your HOLOPHONIX Processor, click on the ‘DEVICE’ menu, select ‘DEVICE VIEW’,

then choose HOLOPHONIX in the drop-down menu:

Sample Rate

From the ‘DEVICE VIEW’, go to the ‘DEVICE CONFIG’ tab, select your HOLOPHONIX processor then go to the ‘DEVICE CONFIG’ tab, and reach for the ‘SAMPLE RATE’ section to adjust this parameter.

note

The HOLOPHONIX web interface displays the sample rate in the ‘AUDIO’ menu of the SETUP view. However, this setting can only be adjusted through the Dante® Controller app.

Network Latency

From the 'DEVICE CONFIG' tab, you can check the current 'receive latency' and change it if necessary:

  • 0.15 ms for networks with a single network switch
  • 0.25 ms for networks with three network switches
  • 0.5 ms for networks where the signal path may go through up to five network switches
  • 1.0 ms for networks where the signal path may go through up to ten network switches
  • 5.0 ms for networks of almost any size

Audio Routing

From the routing tab of the ‘NETWORK VIEW' (main view), you can assign audio channels from and to HOLOPHONIX. Assign to the HOLOPHONIX Dante inputs (receive) channels from other devices (transmitters), such as digital mixers, computers, microphone preamps, etc. Assign the HOLOPHONIX Dante output channels (transmit) to other devices (receivers) such as amplifiers, recording devices, digital mixers, etc. A green icon will appear when the routing is established. Click again to remove the routing. Use 'cmd+click' (mac) or 'ctrl+click' (PC) at the intersection of the devices to perform a diagonal routing.

note

These actions only perform the routing between devices. You will still need to perform inputs/outputs assignations within your devices. For example, on your digital mixer you might need to assign the channels' direct-outs to the mixer's Dante outputs.

Network and IP Address Configuration

By default, the processor's Dante® card is set up to DHCP mode. Use the 'NETWORK CONFIG' tab of the 'DEVICE VIEW' to manually set up the HOLOPHONIX Processor's Dante® Network settings, only if required.

AES 67 Compatibility Mode

To activate the AES compatibility mode, open the 'DEVICE VIEW', then select the 'AES67 CONFIG' tab. Choose 'ENABLE' from the drop-down menu, apply 'CLEAR CONFIG' then 'REBOOT' in the 'RESET DEVICE' section.

  • If you modify the device labels, reboot the Dante in- terface after label modifications to update the AES67 signal name announcement
  • Do not change the bit depth (default 24 bit) from Dante Controller or the console after enabling the AES67 mode.
  • AES67 is Multicast only: create AES67 multicast trans- mission streams in Device View as usual, but tick “AES67 flow” first.
  • In the Routing tab on Dante Controller, the non-Dante AES67 devices will appear in blue as the transmitters.

Clock considerations

  • AES67 mode on a Dante device enables both IEEE 1588 Precision Time Protocol (PTP) v1 and v2. A single clock domain must be created across both PTP v1 and v2 devices
  • Standard Dante devices support PTP v1 only
  • AES67-enabled Dante devices support PTP v1 and PTP v2
  • 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 How to enable the HOLOPHONIX Dante card as Master for both Dante and AES67?
  • Enable the HOLOPHONOIX Dante card “Preferred Master” status
  • Disable “Preferred Master” for all Dante devices that have AES67 disabled.
  • Disable “Sync to External” for all devices.
  • Assign a PTPv2 priority level of between 128 and 255 for all non-Dante devices If another AES67 device (Grandmaster Clock, or another AES67 device) is the Master,
  • Make sure the PTP v2 Master has a priority of be- tween 1 and 100, and is using the “Media Profile” clock settings,
  • Disable “Preferred Master” and “Sync To External” for all Dante devices,
  • One AES67-enabled Dante device will automatical- ly be selected as the Boundary clock, becoming the Dante Master,
  • Make sure the Master Clock device is set to use the “Media profile” (not the “Default profile” because Dante devices do not support the Default profile.
