Antennas, RS-232 Serial Port, Video Connections

Video Connections

Many sources output both audio and video signals (e.g., Blu-ray Disc or DVD player, cable television box, HDTV tuner, satellite box, VCR, DVR). In addition to the audio connection, make one type of video connection for each of these sources (only one at a time for any source).

Digital Video

If you have already connected a source device to one of the HDMI inputs, you have automatically made a video connection, as the HDMI signal includes both digital audio and video components.

Analog Video

There are three types of analog video connections: composite video, S-video and component video.

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

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

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.

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.

CONNECTIONS

Antennas

The AVR 760/AVR 660 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

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.

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.
