Harman-Kardon AVR 254 owner manual To that source

REAR-PANEL CONNECTIONS

Analog 2 and 4 Outputs: Connect either of these analog audio outputs to the analog audio inputs of a recording device. A signal is available at these outputs whenever an analog audio source is playing. However, the AVR 254 does not convert digital audio sources to analog for recording.

Coaxial 1/2 and Optical 1/2 Digital Audio Inputs: If a source has a compatible digital audio output, and if you are not using an HDMI connection for audio for the device, connect it to one of these jacks to hear digital audio formats, such as Dolby Digital, DTS and linear PCM. Use only one type of digital audio connection for each source.

Coaxial Digital Audio Output: If a source is also an audio recorder, connect a coaxial digital audio output to the recorder’s input for improved recording quality. Only PCM digital audio signals are available for recording.

Stereo Jack: Enjoy audio from an iPod (not included), CD player or other portable player by connecting its headphone jack to this input using a 1/8” stereo mini-plug cable (not included). Video and still-image playback are not available at this input.

6-/8-Channel Inputs: Connect the multichannel analog audio outputs of a DVD-Audio, SACD™, Blu-ray Disc™ or HD-DVD™player (or any other external decoder) to these jacks to enjoy these formats.

NOTE: When the multichannel player has an onboard digital decoder, it is not necessary to connect it to the 6-/8-Channel Analog Audio Inputs. Only a digital audio connection (HDMI, coaxial or optical) is needed.

Component Video 1 and 2 Inputs: If a video source (e.g., DVD player or HDTV tuner) has analog component video (Y/Pb/Pr) capability, and if you are not using an HDMI connection for the device, then connect the component video outputs of the source to one of the two component video inputs. Do not make any other video connections

to that source.

Component Video Monitor Outputs: If you are using one of the Component Video Inputs and your television or video display is component-video-capable, and if you are not connecting the HDMI Output to your display, connect these jacks to the corresponding inputs on your video display.

NOTES:

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

•Composite and S-video signals are upscaled to as high as 1080i and available at these outputs. If your video display’s best connection is component video, it is the only video connection required from the AVR to the display.

RS-232 Serial Port: This specialized connector may be used with your personal computer in case we offer a software upgrade for the receiver at some time in the future.

RS-232 Mode: Leave this switch popped out in the Operate position unless the AVR 254 is being upgraded.

RS-232 Reset: This switch is only used during a software upgrade. A standard processor reset is performed by pressing and holding the front-panel OK Button.

Switched AC Accessory Outlet: You may plug the AC power cord of one source device into this outlet, and it will turn on whenever you turn on the receiver. Do not use a source that consumes more than 50 watts of power.

AC Power Cord: After you have made all other connections, plug the AC power cord into an unswitched outlet.
