CONNECTIONS

required for DVD-Audio players compliant with HDMI version 1.1 or better, or HD-DVD and Blu-ray Disc players that decode the digital audio internally and output linear PCM signals in digital format. Consult the owner’s guide for your disc player for more information.

Multichannel analog audio cable (RCA)

The AVR 254 also offers an analog audio input on the rear panel in the form of a stereo 1/8" mini jack. Connect the headphone output of any audio source, such as an MP3 player or portable CD player, to the Stereo Jack input. See Figure 9.

Composite video cable

Figure 10 – Composite Video

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. 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.

Video Connections

Although some sources only produce an audio signal (e.g., CD player, tape deck), many sources output both audio and video signals (e.g., 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 as explained in the Digital Audio Connections section, you have automatically made a video connection at the same time, as the HDMI signal includes both digital audio and video components.

If the source device is not capable of transmitting its digital audio signal through the HDMI connection, use one of the coaxial or optical digital audio inputs for the source.

If a multichannel analog audio connection is required for certain lossless formats (e.g., DVD-Audio, SACD, HD-DVD or Blu-ray Disc), you may make both audio connections. To listen to the multichannel disc, set the Audio Auto Polling setting to the 6/8CH inputs, and the AVR will automati- cally select it when no digital signal is output by the player.

Component video cable

If it’s available on your video display, an HDMI connection is recom- mended 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 are 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.

Antennas

The AVR 254 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.

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, although it is important never to confuse the two. 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.

Figure 13 – FM Antenna

The AM loop antenna needs to be assembled. Connect the two leads to the spring terminals on the receiver. As AM antenna leads have no polarity, it doesn’t matter which of the two terminals is used for either lead. See Figure 14.
