CAUTION: Insufficient power can lead to unpredictable results or damage to the equipment. Please use the Crestron Power Calculator to help calculate how much power is needed for the system (http://www. crestron. com/calculators). · To facilitate connection to a CNX-PAD8A or CNX-BIPAD8, use a Cresnet Distribution Block (such as the C2N-HBLOCK). For more details, refer to "Check Network Wiring" on page 14. Hardware Hookup Connect the Device Make the necessary connections as called out in the illustration that follows this paragraph. Refer to "Network Wiring" above before attaching the 4-position terminal block connector. Apply power after all connections have been made. When making connections to the CNXBRMO, consider the following: · Use Crestron power supplies for Crestron equipment. · The included cable cannot be extended. The CNXBRMO serves as either a bridge for stereo/mono audio in an audio distribution system or can provide all summed mono audio. Stereo/Mono Bridge In a bridged wiring configuration the CNXBRMO should only be used with the Crestron CNAMPX-16X60 (or CNAMPX-12X60) amplifier to provide over 200 watts of power to each speaker. Set the Stereo/Mono switch on the CNXBRMO to create a stereo or mono bridge. Refer to the illustrations on pages 9 & 10 for proper connections. Apply power to the audio distribution system last. Operations Guide ­ DOC. 8158A Bridging/Mono Interface: CNXBRMO · 7 Bridging/Mono Interface Crestron CNXBRMO NOTE: When bridging, no more than two CNXBRMO units should be connected to a single CNAMPX-16X60 (or CNAMPX-12X60). When implementing a two CNXBRMO bridge, Crestron recommends connecting one to ROOM INPUTS 1 & 2 and connecting the other to ROOM INPUTS 7 & 8 on the CNAMPX-16X60 (or ROOM INPUTS 5 & 6 on the CNSMPX-12X60). Failure to make these connections in this particular application may result in damage to the amplifier. 8 · Bridging/Mono Interface: CNXBRMO Operations Guide ­ DOC. 8158A Crestron CNXBRMO CNXBRMO Used as a Stereo Bridge Operations Guide ­ DOC. 8158A CNAMPX-16x60 SET TOGGLE SWITCH TO STEREO 2-Series Control System Cresnet Distribution Block LEFT SPEAKER RIGHT SPEAKER SPEAKERS MUST BE CAPABLE OF HANDLING MORE THAN 200 WATTS NOTE: IN A BRIDGED CONFIGURATION, ONLY USE THE CRESTRON CNAMPX-16X60 (OR CNAMPX-12X60) Bridging/Mono Interface: CNXBRMO · 9 Bridging/Mono Interface CNX-PAD8A CNXBRMO Used as a Mono Bridge Bridging/Mono Interface 2-Series Control System 10 · Bridging/Mono Interface: CNXBRMO CNAMPX-16x60 SET TOGGLE SWITCH TO MONO Cresnet Distribution Block LEFT SPEAKER RIGHT SPEAKER SPEAKERS MUST BE CAPABLE OF HANDLING MORE THAN 200 WATTS NOTE: IN A BRIDGED CONFIGURATION, ONLY USE THE CRESTRON CNAMPX-16X60 (OR CNAMPX-12X60) Crestron CNXBRMO Operations Guide ­ DOC. 8158A CNX-PAD8A Crestron CNXBRMO All Summed Mono Bridging/Mono Interface 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.
