BLU-CP Wiring Instructions

Audio London Series Digital Signal
Processors. It is built on a 2.5” X 6” aluminum

plate with a M ylar overlay on the f ront side of
the plate containing the int eg ra ted switch es and
status LED’s. The switches on t he top of th e
BLU-CP adjust the height of the pulpit. The
middle switc hes adjust th e volu me in the
Cha pel, and between t hese s witc hes ar e five
LED’s that provide a visual indication of the
volume level. The bottom switch turns the
sound system on and off, and it has an LED
associat ed with it for indicating when the s oun d
system is on. On the backside of the BLU-CP is
a single RJ-45 Cat5e connector for connecting
the module to the DSP, and a 3-pin Euro-block

IMPORTANT: CAT5 wiring for the RJ-45 connector needs to be

crimped to TIA/EIA 568B Standards (see below) on both ends of the cable.

You must crimp and test the wiring with an approved CAT5 568A/B
tester before connecting any cable between the BLU-CP and either a
BLU-CIF or BLU-IF Interface unit. Failure to crimp w iring to the correct

standard could possibly lead to component damage.

CAUTION: If th e BLU-C P is b ei ng installed in a remodel, check the

width of the op ening in the pedes tal for proper clearance of the r ibbon cable.
You should not crimp or crush the ribbon cable during the install. If the
opening in the pedestal is too narrow, you can ei ther chisel out m or e
clea r ance or mou nt the BLU-CP up using the enclosed nylon standoffs.
