REAR-PANEL CONNECTIONS Fan Vents: This area contains vents used by the AVR 7550HD's fan฀to฀cool฀the฀system.฀Maintain฀a฀clearance฀of฀at฀least฀3฀inches฀ from the nearest surface to avoid overheating the unit. It is normal for the fan to remain off at most normal volume levels. An automatic temperature sensor turns the fan on only when it is needed. IMPORTANT NOTE: Never block the fan vents, as doing so could allow the AVR to overheat to dangerous levels. Zone 2 Video Output: Connect this composite video jack to a video display located in the remote zone of a multizone system. When the multizone system is in use, viewers in the remote zone will be able to see the AVR's on-screen text menus and any available source video, as long as the source is connected to a Composite Video Input, and that input is specified for that source in the Zone 2 Video setting of the Info Settings menu. Composite and S-Video 1, 2 and 3 Video Inputs: Use these jacks to connect your video-capable source components (e.g., VCR, DVD player, cable TV box) to the receiver. Use only one type of video connection for each source. Composite and S-Video 2 Outputs: Connect one of these analog video outputs to the composite or S-video inputs of a recording device. A signal is available at these outputs whenever an analog video source is playing. Composite and S-Video Monitor Outputs: If any of your sources use composite or S-video connections, connect one or both of these monitor outputs to the corresponding inputs on your฀video฀display.฀If฀your฀video฀display฀is฀equipped฀with฀HDMI฀or฀ component video inputs, these connections are unnecessary, as the AVR 7550HD will convert the composite or S-video source signal to the correct format for a single video-cable connection to the TV. Component Video 1, 2 and 3 Inputs: If a video source has analog component video (Y/Pb/Pr) capability, and if you are฀not฀using฀an฀HDMI฀connection,฀connect฀the฀component฀video฀ outputs of the source to one of the sets of component video inputs. Do not make any other video connections to that source. Component Video Monitor Outputs: If you are using one of the Component Video Inputs and your television or video display is component-video-capable (but does not have HDMI),฀connect฀these฀jacks฀to฀the฀video฀display.฀ NOTES: •฀฀Due฀to฀copy-protection฀restrictions,฀there฀is฀no฀output฀at฀ the฀Component฀Video฀Monitor฀Outputs฀for฀copy-protected฀ sources. •฀฀Composite฀and฀S-video฀signals฀are฀upscaled฀to฀as฀high฀as฀ 1080i and available at these outputs. If your video display's best connection is component video, it is the only video connection required from the AVR to the display. AM and FM Antenna Terminals: Connect the included AM฀and฀FM฀antennas฀to฀their฀respective฀terminals฀for฀radio฀reception. Preamp Outputs: Connect these jacks to an external amplifier if more power is desired. The Surround Back/Zone 2 Preamp Outputs may be used with an external amplifier to power the remote zone of a multizone system. A-BUS Port: Use a Category 5/5e cable to connect this port to optional A-BUS equipment for multizone operation. When the A-BUS system is used, it is possible to have a full 7.2-channel system in the main listening room at the same time the multizone system is in use. Front, Center and Surround Speaker Outputs: Use two-conductor speaker wire to connect each set of terminals to the correct speaker. Remember to observe the correct polarity (positive and negative connections). Surround Back/Zone 2 Speaker Outputs: These speaker outputs are used for the surround back channels in a 7.2-channel home theater, or may be reassigned to a remote room for multizone operation. Switched AC Accessory Outlet: You may plug the AC power cord of one source device into this outlet, and it will turn on whenever you turn on the receiver. Do not use a source that consumes more than 50 watts of power. AC Power Input: After you have made all other connections, plug the AC power cord into this receptacle and into an unswitched wall outlet. 12
