CONNECTIONS

plug on an S-video cable contains four metal pins, plus a plastic guide pin. Be careful to line up the plug correctly when you insert it into the jack on the receiver, source or video display. 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. The “Y” cable is color- coded green, the “Pb” cable is colored blue and the “Pr” cable is colored red. See Figure 12.

Component video cable

If it’s available on your video display, HDMI is recommended as the best quality connection, followed by component video, S-video and then composite video.

NOTES:

•Due to copy-protection restrictions, there is no output at the Component Video Monitor Outputs for copy-protected sources.

•High-resolution 1080i and 1080p video signals are not available at the HDMI Output, but 1080i signals are passed through, as is, to the Component Video Outputs. If your source outputs analog high-resolution video, either use the Component Video Outputs, change the output resolution of your source device to 720p, or connect your source’s component video outputs directly to your video display.

•Due to the design of some video displays, analog 480p or 720p component video source signals may produce artifacts when used with the AVR’s analog video outputs (composite, S-video or component video). If this occurs, try changing the Video Mode setting in the INPUT SETUP menu, or connecting the source device’s video output directly to your video display. However, for best results, we recommend that you consider upgrading to an HDMI-capable video display.

Antennas

The AVR 247 uses separate terminals for the included FM and AM antennas that provide proper reception for the tuner.

The FM antenna uses a 75-ohm F-connector. See Figure 13.

RS-232 Serial Port

The RS-232 serial port on the AVR 247 is used only for data. If Harman Kardon releases a software upgrade for the receiver’s operating system at some time in the future, the upgrade may be downloaded

to the AVR using this port. Complete instructions will be provided at that time.

Figure 13 – FM Antenna

The AM loop antenna needs to be assembled. Then connect the two leads to the screw terminals on the receiver. See Figure 14.
