Professional Balanced Audio
Receiver: CNX-PBAR4
Introduction
Features and Functions
The CNX-PBAR4 Professional Balanced Audio Receiver consists of four identical
differential receiver channels and is designed to work with the Crestron
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 singleended, 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.
