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 certied AC/DC power adapter with limited power source output rated 12V-48V,
30W maximum or a certied PoE+ adapter limited power source output rated 48VDC, 30W maximum. The
unit may be supplied together with a certied 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 rst device in the chain. All devices connected in the London BLU link chain
must be congured 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�
