Operation

Selecting a Digital Source

To utilize either digital mode you must have

properly connected a digital source to the AVR.

Connect the digital outputs from DVD players, HDTV

receivers, satellite systems or CD players to the

Optical or Coaxial inputs on the rear or front panel





. In order to provide a backup signal

and a source for analog stereo recording, the analog

outputs provided on digital source equipment should

also be connected to their appropriate inputs on the

AVR rear panel (e.g., connect the analog stereo audio

output from a DVD to the DVD inputs



on the rear

panel when you connect the source’s digital outputs).

When playing a digital source such as DVD, first select

its input using the remote or front panel controls

as outlined in this manual in order to feed its video

signal (if any) to the TV monitor and to provide its

analog audio signal for recording. When the digital

input appropriate with the DVD player is not selected

automatically (due to the input settings made earlier

during the system configuration, see page 12), select

the digital source by pressing the Digital Input

Selector button

and then using the



buttons

on the remote to choose any of the

eVW

eVW

inputs, as they appear in the Main Information

Display



. When the digital source is playing,

the AVR will automatically detect whether it is

a multichannel Dolby Digital, DTS source or a

conventional PCM signal, which is the standard output

from CD players.

Digital Status

When a digital source is playing, the AVR senses

the type of bitstream data that is present. Using

this information, the correct surround mode will

automatically be selected. For example, DTS bitstreams

will cause the unit to switch to DTS decoding, and

Dolby Digital bitstreams will enable Dolby Digital

decoding. When the unit senses PCM data, from CDs

and some music DVDs or certain tracks on normal

DVDs, it will allow the appropriate surround mode to

be selected manually.

When a digital source is playing, the AVR will display

a variety of messages to indicate the type of bitstream

received. These messages will appear shortly after an

input or surround mode is changed, and will remain

in the Main Information Display



for about

five seconds before the display returns to the normal

surround mode indication.

Surround Mode Types

For Dolby Digital and DTS sources, a three digit

indication will appear, showing the number of

channels present in the data. An example of this type

of display is 3/2/.1.

The first number indicates how many discrete front

channel signals are present.

A 3 tells you that separate front left, center t

and front right signals are available. This will

be displayed for Dolby Digital 5.1 and DTS 5.1

programs.

A 2 tells you that separate front left and right

signals are available, but there is no discrete

center channel signal. This will be displayed for

Dolby Digital bitstreams that have stereo program

material.

A 1 tells you that there is only a mono channel

available in the Dolby Digital bitstream.

The middle number indicates how many discrete

surround channel signals are present.

A 2 tells you that separate surround left and right

signals are available. This will be displayed for

Dolby Digital 5.1 and DTS 5.1 programs.

A 1 tells you that there is only a single, surround t

encoded surround channel. This will appear

for Dolby Digital bitstreams that have matrix

encoding.

A 0 indicates that there is no surround channel

information. This will be displayed for two-

channel stereo programs.

The last number indicates if there is a discrete Low

Frequency Effects (LFE) channel. This is the “.1” in the

common abbreviation of “5.1” sound and it is a special

channel that contains only bass frequencies.

A .1 tells you that an LFE channel is present. This t

will be displayed for Dolby Digital 5.1 and DTS 5.1

programs, as available.

A 0 indicates that there is no LFE channel t

information available. However, even when there

is no dedicated LFE channel, low frequency sound

will be present at the subwoofer output when the

speaker configuration is set to show the presence

of a subwoofer.



message may appear in the Lower

Display Line



. This is your indication that the

digital audio data stream has been interrupted or is

no longer present. When that occurs, the unit’s digital

signal processor has no signal to lock onto, and is

thus “unlocked”. You may see this message when a

DVD is first started until the stream is playing and

the processor determines which mode to apply; or

any time the data stream is stopped or paused, such

as when the menus of some discs are displayed or

when the player is switching between the different

sections of a disc. You may also see the message when

a satellite receiver, cable set-top or HDTV tuner is in

use if the digital audio is temporarily interrupted when

channels are changed or when a cable box switches

from a channel with a digital data stream to a channel

with analog audio only. The



message is

normal, and does not indicate any problem with your

receiver. Rather, it tells you that the incoming data has

simply been paused or is not present for a variety of

possible reasons.

When Dolby Digital 3/2/.1 or DTS 3/2/.1 signals are

being played, the AVR will automatically switch to the

proper surround mode, and no other processing may

be selected. When a Dolby Digital signal with a 3/1/0

or 2/0/0 signal is detected you may select any of the

Dolby surround modes.

It is always a good idea to check the readout for the

channel data to make certain that it matches the audio

logo information shown on the back of a DVD package.

In some cases you will see an indication for “2/0/0”

even when the disc contains a full 5.1, or 3/2/.1 signal.

When this happens, check the audio output settings

for your DVD player or the audio menu selections for

the specific disc being played to make certain that the

player is sending the correct signal to the AVR.
