Rear Panel
12-48VDC 25W [Power Connector]
The BLU-50 can be powered via either an external universal 12VDC power supply (included), 12-48VDC 30W
supply, or via PoE+� Connect the 12VDC power supply here if not using PoE+�
This model shall be powered by a certified AC/DC power adapter with limited power source output rated 12V-48V,
30W maximum or a certified PoE+ adapter limited power source output rated 48VDC, 30W maximum. The
unit may be supplied together with a certified AC/DC power adapter from FranMar International Inc., model
FRA030E-S12-4, rated 100-240V~, 50-60Hz, 0�7A, Class I�
Locate
Pressing the Locate switch on the rear of the unit will illuminate the PWR LED on the front and identify the device
within London Architect� Similarly the switch will illuminate if the device is located from within London Architect�
RS232
Serial port for connection of external control equipment�
PoE / Ethernet
If not using a 12VDC power supply, power the BLU-50 via PoE+ here� This can be accomplished by either using a
PoE+ compliant network switch, or a PoE+ midspan injector� This is also the main connection for the proprietary
system control network, and for third-party Ethernet control�
BLU link
London BLU link is a point-to-point digital audio bus with 256 audio channels at 48K sample rate or 128 audio
channels at 96K sample rate� The BLU-50 allows access to channels 1-48 of this bus, at 48K sample rates� The
physical connection is made with Cat 5e cable from the OUT port of one device to the IN port of another device�
The devices are connected in a daisy chain fashion continuing with the OUT port of one device connected to the
IN port of the next device� Redundancy can be provided by completing the loop and connecting the OUT port from
the last device to the IN port of the first device in the chain. All devices connected in the London BLU link chain
must be configured for the same audio sample rate.
Analogue Input/Output Connections
There are 4 analogue input connections and 4 analogue output connections� The analogue connections are
balanced, on Phoenix/Combicon connectors�
