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.
