CONNECTIONS Composite video is the basic connection most commonly available. The jack is usually color-coded yellow, and looks like an analog audio jack. Do not plug a composite video cable into an analog or coaxial digital audio jack, or vice versa. Both the chrominance (color) and luminance (intensity) components of the video signal are transmitted using a single cable. See Figure 10. Composite video cable Figure 10 - Composite Video S-video, or "separate" video, transmits the chrominance and luminance components using separate wires contained within a single cable. The plug on an S-video cable contains four metal pins, plus a plastic guide pin. Align the plug correctly when you insert it into the jack. See Figure 11. S-video cable Figure 11 - S-Video Component video separates the video signal into three components - one luminance ("Y") and two sub-sampled color signals ("Pb" and "Pr") - that are transmitted using three separate cables. See Figure 12. Component video cable Y Green Pb Blue Pr Red Figure 12 - Component Video If฀it's฀available฀on฀your฀video฀display,฀an฀HDMI฀connection฀is฀recommended as the best quality connection, followed by component video, S-video and then composite video. NOTES: •฀฀Copy-protected฀sources฀are฀not฀available฀at฀the฀Component฀ Video฀Monitor฀Outputs. •฀฀Standard฀and฀high-definition฀analog฀video฀signals฀may฀ be upscaled to 1080i resolution for the Component Video Monitor฀Outputs.฀For฀improved฀video฀performance,฀consider฀ upgrading฀to฀an฀HDMI-capable฀video฀display฀with฀1080p฀ resolution. The฀AM฀loop฀antenna฀needs฀to฀be฀assembled.฀Connect฀the฀two฀leads฀ to฀the฀spring฀terminals฀on฀the฀receiver.฀The฀AM฀antenna฀leads฀have฀ no polarity, and you may connect them to either terminal. See Figure 14. Figure฀14฀-฀AM฀Antenna To฀enjoy฀XM฀satellite฀radio,฀purchase฀an฀XM฀Ready฀antenna฀module฀ and฀a฀subscription฀to฀the฀XM฀service.฀The฀XM฀Mini฀Tuner฀and฀Home฀ Dock Bundle, available at www.xmradio.com, is recommended. The older Connect-and-Play module is also compatible with the AVR 7550HD, but it may no longer be available. Although you may use a module with standard audio connections, labeled for "car and home use," you will not be able to enjoy the AVR 7550HD's ease of control. RS-232 SERIAL PORT The RS-232 serial port may be connected to an external computer or control device to allow the external device to transmit control commands to the AVR. The port is bidirectional, so that the AVR can transmit status updates to the control device. Connecting and using the RS-232 port requires technical knowledge, and is best left to a professional custom installer. ANTENNAS The฀AVR฀7550HD฀uses฀separate฀terminals฀for฀the฀included฀FM฀and฀ AM฀antennas.฀ The฀FM฀antenna฀uses฀a฀75-ohm฀F-connector.฀See฀Figure฀13. Figure฀13฀-฀FM฀Antenna 21
