20CONNECTIONSComposite video is the basic connection most commonly available.The jack is usually color-coded yellow, and looks like an analogaudio jack. Do not plug a composite video cable into an analog orcoaxial digital audio jack, or vice versa. Both the chrominance(color) and luminance (intensity) components of the video signalare transmitted using a single cable. See Figure 10.Figure 10 – Composite VideoS-video, or “separate” video, transmits the chrominance and lumi-nance components using separate wires contained within a singlecable. The plug on an S-video cable contains four metal pins, plus aplastic guide pin. Align the plug correctly when you insert it into thejack. See Figure 11.Figure 11 – S-VideoComponent video separates the video signal into three compo-nents – one luminance (“Y”) and two sub-sampled color signals(“Pb” and “Pr”) – that are transmitted using three separate cables.See Figure 12.Figure 12 – Component VideoIf it’s available on your video display, an HDMI connection is recom-mended as the best quality connection, followed by componentvideo, S-video and then composite video.NOTES:• Copy-protected sources are not available at the ComponentVideo Monitor Outputs.• Standard and high-definition analog video signals maybe upscaled to 1080i resolution for the Component VideoMonitor Outputs. For improved video performance, considerupgrading to an HDMI-capable video display with 1080presolution.ANTENNASThe AVR 7550HD uses separate terminals for the included FM andAM antennas.The FM antenna uses a 75-ohm F-connector. See Figure 13.Figure 13 – FM AntennaThe AM loop antenna needs to be assembled. Connect the two leadsto the spring terminals on the receiver. The AM antenna leads haveno polarity, and you may connect them to either terminal. SeeFigure 14.Figure 14 – AM AntennaTo enjoy XM satellite radio, purchase an XM Ready antenna moduleand a subscription to the XM service. The XM Mini Tuner and HomeDock Bundle, available at www.xmradio.com, is recommended.The older Connect-and-Play module is also compatible with theAVR 7550HD, but it may no longer be available. Although you mayuse a module with standard audio connections, labeled for “carand home use,” you will not be able to enjoy the AVR 7550HD’sease of control.RS-232 SERIAL PORTThe RS-232 serial port may be connected to an external computeror control device to allow the external device to transmit controlcommands to the AVR. The port is bidirectional, so that the AVR cantransmit status updates to the control device. Connecting and usingthe RS-232 port requires technical knowledge, and is best left toa professional custom installer.Componentvideo cableGreenBlueRedYPbPrS-video cableCompositevideo cable
