Console Setup & Operation
To ensure correct operation of this system, it is necessary to ensure that the console and session settings are correct.
Each Optically connected device must have a unique ID. On each console, open the Network panel on the Master Screen. From
the drop down list at the top of the panel, set the ID of each console. We would recommend setting the FOH console to ID1 and ID2
and the monitor console to ID3 and ID4. Even numbered ID's are used for Redundant engines in Mirrored engine setups therefore if
you were mirroring two single engine consoles, they should be set as ID1 for the FOH console and ID3 as the Monitor console.
Similarly, each SDRack should have it’s ID set. Rack ID’s start from 11; this example uses Optocore ID’s 11 & 12 for the 2 con-
nected racks.
On each console, ensure that the session sample rates are the same. The sample rate is set in the Files > Session Structure
panel.
Open the Setup > Audio Sync panel and set the Sync source to be Optocore. Do this on both engines of both consoles.
Save and Send the Session from the A engine on each console to its B engine and Mirror each pair of engines.
Then open the Setup > Audio IO panel on the A engine of both consoles, and press the Conform All Ports button in the bottom
left corner. The console will “look” down the connected optical fibre cables and auto discover and conform all the racks it can
find. In this example, they will find 2 optic stage racks.
If the conformed racks in each of the engine's Audio IO panels do not match the other console, then the system will not map
correctly. Before the system is mapped, you should allocate any SDRack output cards. Press the Setup Optocore button select
/ deselect output cards as required. Once this is complete, press the Remap All Optocore button.
[For more detailed information on the Optocore Setup, please refer to Optocore_221_User_D.pdf which is available for download
from the Support section of the DiGiCo website and as an Appendix to this manual.]
In its default setup, none of the optocore connected SDRacks will be defined as shared. This means that either console will be
able to control the rack and adjust Mic Amp Gain, Phantom Power, output pads etc.
If you are happy for either desk to control the racks, then you can leave the sessions with these default settings. Making changes
to this default state allows you to define the shared status of each rack. If you set a rack to be in full control, then that console
will have full control of the rack. If you set a rack to be in receive only mode, then that console will not be able to make changes to
mic amp gain etc, but will “see” the changes made by the other console. This is necessary for Gain Tracking to function. The third
option is isolate, and when in this mode, the console will not be able to make changes, nor see changes made by someone else.
Gain tracking will not work if the rack is set in isolate mode.
To set a console as the master controller for the racks : In the Audio IO Panel, select the appropriate stage rack. Press the Splits
and Sharing button. In the section titled Selected Rack, press the shared button. It will default to the Isolate setting. Then press
the full control button. A warning will remind you that going into full control may affect the live audio.. then press Yes. If required,
repeat this process for the second stage rack.
To set racks to be in receive only mode : In the Audio IO Panel, select the appropriate stage rack. Press the Splits and Sharing
button. In the section titled Selected Rack, press the shared button. It will default to the Isolate setting. Then press the receive
only button. A warning will remind you that your session will change to correctly reflect the actual settings on the rack.. then
press Yes. If required, repeat this process for the second stage rack.
