How to split more than 64 channels
Posted by Nicola Beretta, Last modified by Nicola Beretta on 13 April 2016 01:20 PM

We are working on a new range of option cards for dLive which will take full advantage of the I/O Ports, offering 128ch at 96kHz.

However the current range of iLive / GLD option cards can be used with the M-DL-ADAPT interface to provide a digital split of 64 or more channels.

Here below are two examples of a 128ch digital split.

 

Using ACE cards

- Each card provides a 64x64 interface.

- Connections must be point to point (2 cables required from Master rack to Slave rack)

- Set Master rack to Internal clock in the MixRack / Audio / AudioSync menu

- Set Slave rack to I/O Port 1 in the MixRack / Audio / AudioSync menu

- Use the I/O / Tielines screen to patch MixRack Inputs to I/O Port 1 & 2 on the Master rack

- Use the I/O / Inputs screen to patch I/O Port 1 & 2 inputs to Input channels on the Slave rack

 

Using Dante cards

- Each card provides a 64x64 interface

- All Dante cards must be on the same Dante network, and set to Switched mode

- Connect the cards using one of the following topologies, as shown in the diagrams below:

  • Bridge I/O Port 1 & 2 on the Master and Slave rack, and connect the Master I/O port 1 to the Slave I/O Port 1
  • Bridge I/O Port 1 & 2 on the Master rack only, and connect Master I/O Port 1 to Slave I/O Port 1, and Master I/O Port 2 to Slave I/O Port 2
  • Connect all 4 cards to a Gigabit Ethernet switch

        

Note - use only the Primary and Secondary ports for audio connections. Use the Control Network port for Dante Controller.

- Set Master rack to Internal clock in the MixRack / Audio / AudioSync menu

- Set Slave rack to I/O Port 1 in the MixRack / Audio / AudioSync menu

- In Dante Controller, set one of the cards in the Master rack to Preferred Master and Enable Sync to External

Note - to correctly identify the cards we recommend you connect your laptop to the Primary port of each card separately, and rename the card according to its position

- Check all other cards have no clock option ticked

- In Dante Controller, patch signals from Master I/O Port 1 to Slave I/O Port 1, and from Master I/O Port 2 to Slave I/O Port 2

- Use the I/O / Tielines screen to patch MixRack Inputs to I/O Port 1 & 2 on the Master rack

- Use the I/O / Inputs screen to patch I/O Port 1 & 2 inputs to Input channels on the Slave rack
