The BLU-CIF Interface Board provides a simple wiring interface for the BLU-CC, BLU-CP, BLU-CS and BLU-IR modules to the BSS London Series of Digital Signal Processors for LDS chapel installations. It provides LED status indicators, the appropriate connections for each of the controls, and relays for tiggering the turn on of external equipment and switching of speaker level signals for audio in overflow areas. The BLU-CIF is used for single chapel configurations. The connections on the BLU-CIF consists of 3.5mm eurostyle blocks for existing wiring, and RJ-45 connectors for Cat5e wiring. It also ships with two pre-fabricated cables for connecting it to the DSP. The board is powered by an external 24VDC table top power supply (included with each unit).
