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.
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.
Figure 12 – Component Video
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.
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.

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.
