DL451 Modular I/O
Operator Manual
Stage rack 2
Stage rack 2, also known as the “DL461/DL471 engine rack”, contains the two routers
and 10 DSP units.
Important:
In general, the physical location of the hardware units within each rack is not
critical, and alternative configurations are acceptable for different packaging
preferences. However, best practice is to mount the DL471 units in numerical
order, which will aid quick identification and fault finding.
DL471 unit ID numbers are located on stickers on the top cover of each device and also
on the carton. These must be noted prior to build-up and connected, as shown, in
numerical sequence. Please note that once initially configured, the ID numbers are
displayed on the top row of the DL471 screen and role numbers are on the bottom row.
The role numbers are dynamic and, therefore, may change during system operation.
Wiring instructions
This section gives the system cabling details for the XL8-specific equipment and,
although it is laid out in recommended order, this order is not critical.
When making the connections, please make sure they match those in “XL8 system
interconnections” on page 60. Further details are shown in “Cable type and function”
on page 62.
>> To connect both routers together
Important:
Without this connection system snake redundancy will be compromised.
Connect the routers via their Ethernet socket of the control expansion section on
each router’s rear panel (see “System interconnection panel” on page 253).
>> To connect the XL8 to the routers
Connect the ‘snake’ (optical or copper) from the X snake socket on the rear of the XL8
Control Centre to the appropriate snake socket on the X Router. Repeat for the Y
Router using the Y socket on the XL8 Control Centre.
>> To connect the routers to the DSPs (Stage rack 2)
•In AES50 audio - bank 0 on the X router, connect the 10 sockets to the AES50
audio X socket on the DSP units. Repeat for the Y router, using the equivalent Y
sockets.
•In Ethernet control bank on the X router, connect the 10 sockets to the Ethernet
control X socket on the DSP units. Repeat for the Y router, using the equivalent Y
sockets.
>> To connect the routers to the Stage rack 1 units
• Mic splitters: In AES50 audio - bank 1 on the X router, connect sockets 1 and 2 to
the AES50 audio - A X sockets on the Mic Splitters. Repeat for Y router, using the
mic splitters’ Y sockets.
• Line I/O units: In AES50 audio - bank 1 on the X router, connect sockets 5 and 6
to the AES50 audio X sockets on the line I/O units. Repeat for Y router, using the
line I/O units’ equivalent Y sockets.
