CAUTION: Check the speaker wires for shorts and frayed wiring around the OUTPUT connectors. NOTE: For optimum performance, Crestron recommends the optional CBL-PRO-XLR-2 XLR Balanced Audio Interface Cable Kit (two-foot cable length) or CBL-PRO-XLR-6 Balanced Audio Interface Cable Kit (six-foot cable length) to connect to the PSPHD or other pre-amplifier. Hardware Connections for the PROAMP-7X250 LAN: 10/100 Base-T Ethernet to LAN Or PSPHD INPUT: From PSPHD Or Other Preamplifier NET: To Cresnet Devices POWER: From Line Voltage OUTPUT: To Speakers GROUND: Tie To Preamplifier Ground NETWORK/DIRECT Switch The NETWORK/DIRECT switch is used to select the connection between the amplifier and a PSPHD. Move the switch to the appropriate position for the connection to be used and connect the LAN port as described below: · · DIRECT: If using a direct connection to the PSPHD, connect an Ethernet cable from the LAN port on the amplifier to the LAN port on a PSPHD. NETWORK: If using a network connection to the PSPHD, connect an Ethernet cable from the LAN port on the amplifier to the local area network. When using a network connection, the PSPHD and the amplifier must be on the same subnet. NOTE: Power must be cycled if the switch is moved. For more information, refer to "Pairing" on page 15. Operations Guide ­ DOC. 6974A PROCISETM Surround Sound Amplifier: PROAMP(I)-7X250 · 13 PROCISETM Surround Sound Amplifier Crestron PROAMP(I)-7X250 PROCISE Amplifier Connections Refer to the following diagram to properly connect the PROAMP-7X250 to a PSPHD Surround Sound Processor. Connect a PROAMP-7X250 to a PSPHD Surround Sound Processor NOTE: For optimum performance when connecting a source to a PROCISE amplifier, Crestron recommends the optional CBL-PRO-XLR-2 Balanced Audio Interface Cable Kit (two-foot cable length) or CBL-PRO-XLR-6 Balanced Audio Interface Cable Kit (six-foot cable length). Override Mode The Override mode turns on all amplifier channels and ignores any commands from a control system or PSPHD (if connected). Use the Override mode to test the amplifier prior to installation in a system. With the amplifier powered on, press the OVERRIDE/SETUP button on the rear of the PROAMP-7X250. The amplifier will be in the Override mode and the associated LED will light. Press OVERRIDE/SETUP to exit the Override mode. 3. 14 · PROCISETM Surround Sound Amplifier: PROAMP(I)-7X250 Operations Guide ­ DOC. 6974A Crestron PROAMP(I)-7X250 Pairing PROCISETM Surround Sound Amplifier NOTE: Pairing is for use with the PSPHD only. The PROAMP-7X250 can be paired with a PSPHD Surround Sound Processor for control and monitoring of the amplifier. Use the connection type that best fits the application: · DIRECT: Choose DIRECT for a quick installation test without networking or LAN setup. The LAN port of the amplifier connects directly to the LAN port of the PSPHD. The following diagram shows a typical system arrangement where a PSPHD is directly connected to the amplifier. To later integrate with a control system program controlling via the LAN, the pairing process must be executed again when the amplifier is installed on a network.
