Crestron CNXBRMO Bridging/Mono Interface
All Summed Mono
To use a single CNXBRMO to provide four mono output signals (two
with normal polarity and two with inverted polarity) from a single stereo
source, simply set the Stereo/Mono switch on the CNXBRMO to Mono
and make the connections shown in the illustration on the next page.
Apply power to the audio distribution system last.
NOTE: Multiple CNXBRMO units may be used in a single “all summed
mono” system (up to four CNXBRMO units per CNAMPX-16X60 or
three CNXBRMO units per CNAMPX-12X60).
