Hardware Connection
Example 1
The X6R units (analog to AES/EBU converters) are connected to a DD32R-FX using Optocore BI-B cables as
shown in Fig. 1... The word clock is transmitted through the word clock I/Os using standard 75
Ω
cables. The
following figure demonstrates the configuration of a 48 send and 16 return system with four Optocore X6R units
using two input cards each, two X6R units with one input and one output card each and one DD32R-FX.
Fig. 1: Connection of four X6R units and one DD32R
In this example Ports A and B of the DD32R-FX are configured as inputs, receiving AES/EBU signals from two
X6Rs which are equipped with 16 microphone inputs each. Ports C and D are connected to two X6Rs with 8
inputs and 8 outputs each, which transmit four AES/EBU (8 audio channels) outputs and receives four AES/EBU
inputs. The configuration of the ports as inputs and/or outputs and the routing is carried out with OPTOCORE
CONTROL software. The control data is transmitted via the AUX pins in the BI-B cables, the control of the
preamps by software or from the console is possible without any further wiring. For word clock distribution, the
Word Clock OUT of the DD32R-FX should be connected to the Word Clock IN of one X6R. Then using a daisy
chain of BNC cables, the word clock is passed on to the other X6Rs in the system, from the Word Clock OUT to
the Word Clock IN of the consecutive X6R, etc. creating a Word Clock daisy chain. Last X6R device in the word
clock daisy chain should be terminated in the Optocore Software.. The BI-B cables (audio and control data
transmission) and the BNC cables (word clock) are connected as shown in Fig. 1.
