 Note that DMI Cards and SD Rack (Local) cards must not be “hot swapped” – to insert or remove cards,
please power down the 4REA4 Unit first.
15.1 4REA4 I/O Control Via DiGiCo SD Console
A DiGiCo SD console can control the I/O connected to a 4REA4 via either a DMI-MADI (B or C) or a DMI-
Opto. Sockets of I/O either on or connected to the 4REA4 can be tie lined to the connection to the SD
console on a per socket basis. The SD console will then be able to send/receive audio from these ports and
control socket parameters such as gain and phantom power.
NOTE: Currently in this configuration the SD Console session must be running at 96KHz to match the
sample rate of the 4REA4.
Tie Lines can be set in the Routing -> Tie Lines view. A Tie Line will allow audio and control data. If using a
DMI-Opto, up to 64 input tie lines and 64 output tie lines can be made. A DMI-MADI will allow up to 56 inputs
and 56 output tie lines to an SD console. Consecutive tie lines do not have to be from the same source.
Input and output tie lines must be routed separately.
Once the 4REA4 has been set up with the correct DMI card settings (see the relevant DMI card section) and
Tie Lines are in place, in the SD Console Audio I/O window, a “4REA4 Port” can be added from the Add Port
drop down menu and then using the Conform Port function or by using the Conform All Ports function.
This will populate that port with the relevant socket types that have been declared and “tie-lined” in the
4REA4.
When 4REA4 Rack input sockets are subsequently routed into channels on the SD console, the relevant
analogue gain and +48V controls will be available in those channels. For output sockets, the output pads
can be toggled and for AES the SRC state can be turned on or off.
