CONNECTIONS

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. Be careful to line up the plug correctly when you insert it into the jack on the receiver, source or video display.

Figure 10 – S-Video

Component video separates the video signal into three components – one luminance (“Y”) and two subsampled 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 col- ored red.

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

Antennas

The AVR 145 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.

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

RS-232 Serial Port

The RS-232 serial port on the AVR 145 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.
