CNXRMCLV Room Solution Box and CNX-BIPAD8 Audio Distribution Processor. Balanced output of local audio sources from the CNXRMCLV room box is routed via CAT5 cabling to the CNX-PBAR4 at the head-end. The balanced audio is buffered and routed from the CNX-PBAR4 to a CNX-BIPAD8 for additional distribution. The CNX-PBAR4 also converts the signal from balanced to single- ended, and outputs the audio on RCA jacks. This line-level audio is routed to a CNX-BIPAD8 or CNX-PAD8A for distribution to other room boxes, amplifiers, or CNX-BIPAD8s. Balanced audio from a CNX-BIPAD8 can also be supplied via CAT5 to the CNX-PBAR4 and passed through to a CNXRMCLV. For detailed information, refer to the simplified configuration diagram described in “Hookup” which begins on page 7. This non-Cresnet. unit is a key component for distributing audio throughout an entire home, using standard CAT5 cabling. The unit does not require a Cresnet ID or definition in a Crestron SIMPL Windows program. Functional Summary Text Box: · 4 RJ45 Connectors for CAT5 I/O to Room Boxes · 4 RJ45 Connectors for CAT5 I/O to Audio Distribution Processors · 8 RCA Connectors (2 per Group) for Line-Level Audio Output to Other Room Boxes, Amplifiers, and Audio Distribution Processors.
