Once you have completed the setup and
configuration of your new receiver, it is
simple to operate and enjoy. The following
instructions will provide the steps needed
to enjoy the AVR45RDS:

• When using the AVR45RDS for the first
time, it is necessary to press the 

button 

1

on the front panel to

turn the unit on. This places the unit in a
standby mode, as indicated by the amber
color of the

may be used to connect a device such as a
video game or camcorder to your home
entertainment system on a temporary
basis.

• When a pure audio source (Tuner, CD,
Tape Monitor, 6 channel direct inputs) is
selected the last video input used remains
routed to the

‡

. This permits

simultaneous viewing and listening to
different sources.

• During a listening session you may wish
to adjust the 

5

and 

6

controls to suit your listening tastes. Note
that these controls are never effective in
the Dolby Digital mode or if the 6 channel
direct inputs are selected.

• Adjust the volume to a comfortable level
using the front panel

One of the most important features of the
AVR45RDS is its ability to reproduce a full
multichannel surround sound field from
Dolby Digital sources, analog matrix
surround encoded programs and standard
stereo programs. In all a total of seven
listening modes are available on the
AVR45RDS.

Selection of a surround mode is based on
personal taste, as well as the type of pro-
gram source material being used. For
example, motion pictures or TV programs
bearing the logo of one of the major sur-
round encoding processes, such as Dolby
Surround, DTS

†

Stereo or UltraStereo

††

may be played in either the Dolby Pro
Logic, Dolby 3-Stereo or Movie Surround
(Hall 1/2, Theater) depending on the
source material.

NOTE: Once a program has been encoded
with surround information, it retains the
surround matrix as long as the program is
broadcast in stereo. Thus, movies with
surround sound will carry surround
information when they are broadcast via
conventional TV stations, cable, pay TV
and satellite transmission. In addition, a
growing number of made-for-television
programs, sports broadcasts, radio dramas
and music CDs are also recorded in
surround sound. You may obtain a list of
these programs and discs from the Dolby
Laboratories web site at www.dolby.com

DOLBY DIGITAL

DOLBY PRO LOGIC

DOLBY 3 STEREO

THEATER

HALL 1 and HALL 2

STEREO

This mode is available only when the source material is encoded with Dolby Digital
(AC-3) data. It provides up to five separate main audio channels and a special
dedicated Low-Frequency Effects channel.

Dolby Pro Logic is the standard mode for analog surround sound decoding. It uses
information encoded in a two-channel stereo recording to produce four distinct
channels: Left, Center, Right and Surround. Use this mode for accurate
reproduction of programs bearing the Dolby Surround, DTS Stereo, UltraStereo or
other “Surround” logos. Surround encoded programs include videocassette, DVD
and LD movies, TV and cable programs, radio programs and audio CDs. Dolby Pro
Logic processing may also be used to provide a pleasing surround effect with some
stereophonic source material that does not carry surround encoding.

Dolby 3 Stereo uses the information contained in a surround encoded or two-
channel stereo program to create center channel information. In addition, the
information that is normally sent to the rear channel surround speakers is
carefully mixed in with the front left and right channels for increased realism. Use
this mode when you have a center channel speaker, but no surround speakers.

Theater Surround processing uses matrix surround decoding to simulate a
standard movie or stage theater.

These modes are designed for use with stereo recordings. They provide a sound-field
effect that simulates the complex combination of direct and reflected sounds that
create the rich reverberant atmosphere of a medium-sized concert hall (Hall 1) or
a larger concert hall (Hall 2).

This mode turns off all surround processing and presents the pure left and right
channel presentation of two channel stereo programs.

When a program is not listed as carrying
intentional surround information, you
may find that Pro Logic or Dolby 3-Stereo
modes often deliver enveloping surround
presentations through the use of the
natural information present in all stereo
recordings. However, for stereo, but non-
surround programs, we suggest that you try
the Hall 1, Hall 2 or Theater modes.

Surround modes are selected using either
the front panel controls or the remote. To
select a surround mode from the front
panel, simply press the button that
corresponds to the desired mode 

( Ó Ô

Note that the Dolby Digital Mode may only
be selected when a digital input (coaxial,
optical) is selected. For more information
on Dolby Digital, see the following section
of this manual.

To listen to a program in traditional two-
channel stereo, using the front left and
front right speakers only (plus the
subwoofer if installed and configured),
press the 

button

on the

front panel, or follow the instructions
shown above for using the remote until

Dolby Digital
Dolby Digital (also known as AC-3) is the
latest advancement in surround-sound
technology, delivering up to five full-range
surround channels (left, center, right, left
surround and right surround) plus a
special dedicated Low-Frequency Effects
(LFE) channel. This represents a major
advancement over traditional analog
surround in that each surround channel is
fully discrete and capable of full
bandwidth reproduction. Dolby Digital is
available on DVD and LV discs, and it will
be a part of some systems. Dolby Digital for
the home is based on the same system used
to deliver digital audio sound tracks in
movie theaters, enabling true cinema
reproduction in your home.

To utilize the Dolby Digital mode you must
have a digital source properly connected to
the AVR45RDS. Connect the Digital
datastream outputs from DVD players, DTV
receivers and CD players to the 

or 

inputs on

the rear panel 

° ·

. In order to provide a

backup signal and a source for recording,
the analog outputs provided on digital
source equipment should also be
connected to their appropriate inputs on
the AVR45RDS rear panel (e.g., connect the
analog stereo audio output from a DVD to
the 

inputs 

¶

on the rear panel

when you connect the digital outputs.)

When playing back a digital source, first
select the input (CD or DVD) using the
remote or front panel controls as usually,
in order to feed the video signal to the TV
monitor and to provide an analog A/V
signal for recording. Next select the digital
source by pressing the appropriate 

button 

w ˆ

and then using the

¤

button 

g

on the remote or the

buttons

¸

on the front panel to

choose either 

COAXIAL

or

OPTICAL

, as it appears in the 

V

. Press the 

button 

i ˜

to enter the desired choice.

Note, that a digital input (f.e. coaxial)
remains selected for the input source 
(f.e. DVD) as soon as it’s memorized in the
way outlined above, thus the digital source
must not be re-selected each time the
appropriate input choice is made. When
the digital source is playing, the AVR45RDS
will automatically detect if it is a
multichannel Dolby Digital source or a
conventional PCM signal, which is the
standard output from CD players. An
indicator will light in the Information
Display to confirm the digital signal is 

H

or 

I

and if the source is

E

or 

G

.

When an AC-3 source is playing, the
AVR45RDS will automatically switch to the
Dolby Digital surround mode if not so
already. It is important to note, however,
that not all AC-3 sources are encoded with
the full complement of five channels plus
LFE. When a digital source is playing, the

V

will

change to show the input source and
digital type (

or 

). When a

source with Dolby Digital encoding is
playing, the input source name will appear
in the Information Display, followed by a
numeric key to the type and number of
channels being decoded as follows:

3/2.1:

This message appears when a

full complement of Dolby Digital signals is
present: 3 front channels (left, center and
right), 2 surround channels (surround left
and surround right) and “1” channel,
which is the dedicated Low Frequency
Effects (LFE) channel.

26

3/1:

This message indicates the AC-

3 system is decoding a standard Dolby
Pro Logic signal with left, center and
right front channels and a signal mono
surround channel.

2/0:

This message indicates that the

AC-3 system is decoding a traditional
two-channel stereo signal and that no
center, surround or LFE signals are
present.

1+1:

This is a monaural signal that

plays the same information in both the
left front and right front speakers. There
is no sound sent to the center or
surround speakers.

1/0:

This is a monaural signal that

plays through the center channel
speaker only. There is no sound at the
front left/right or surround speakers.

A special feature of Dolby Digital is the
Night mode, which enables AC-3 input
sources to be played back with their full
range while reducing the maximum peak
level by 

1/4

to 

1/3

. This prevents abruptly

loud transitions from causing disturbances
without reducing the impact of the digital
source in the remaining level range. The
Night mode is available only when AC-3
signals are being played.

To engage the Night mode, press the

button

j

on the remote and note

that the 

indicator 

K

will

illuminate in the Information Display.

1. When the digital playback unit is in a
pause, fast forward or chapter search mode
the digital audio data may momentarily
stop, causing a 

NO DATA

message to be

displayed. This is normal and does not
indicate a problem with either the
AVR45RDS or the source machine. The
AVR45RDS will return to Dolby Digital/AC-
3 playback as soon as the data is available
when the machine is in a standard play
mode.

2. The AVR45RDS will decode digital audio
sources with a sampling frequency of
32kHz, 44.1kHz and 48kHz. Although this
will enable it to decode virtually all DVD
movies, CD and MD sources, it is possible
that some future digital sources may not be
compatible with the AVR45RDS.

NOTE: In order to play the Dolby Digital
signals that are recorded on laser discs,
you must have both a laser disc player with
an RF output, and an optional, outboard
RF-to-data demodulator. To listen to Dolby
Digital LD discs, connect the AC-3/RF
output of the player to the demodulator,
and connect the output of the demodulator
to the 

or 

inputs 

° ·

on the rear panel of the AVR45RDS. DO
NOT connect the AC-3/RF output of a laser
disc player directly to the AVR45RDS.

3. Note that not all programs recorded in
Dolby Digital contain full 5.1 channel audio.
Consult the program guide that accompa-
nies the DVD or laser disc to determine
which type of audio has been recorded on
the disc. The AVR45RDS will automatically
sense the type of digital surround encoding
used on an AC-3 program source and adjust
to accommodate it.

4. When a Dolby Digital source is playing,
you may not select any of the analog
surround modes.

5. It is not possible to record the output of
a Dolby Digital program (recording its
analog two channel audio track see 
page 29).

PCM Audio Playback
PCM (Pulse Code Modulation) is the non-
compressed digital audio system used for
compact discs, Mini discs (MD) and non-
AC-3 laser discs. The digital circuits in the
AVR45RDS are capable of high-quality
digital-to-analog decoding, and they may
be connected directly to the digital audio
output of your CD, MD or LD player.

Connections should be made to the 

or 

inputs

° ·

on the rear panel, using whichever

input is not occupied by an AC-3 source
such as a DVD player.

To listen to a PCM digital source, first select
the input for the desired source (e.g., CD).
Next press the 

button 

w ˆ

and

then using the 

⁄

¤

buttons 

g

on the

remote or the

buttons

¸

on the

front panel until the desired choice of either

COAXIAL

or 

OPTICAL

, as it appears

in the 

V

.

Press the 

button 

i ˜

to enter the

desired choice.

When a PCM source is playing, the 

indicator 

I

will light, and the Main

Information Display will show the input
source and the digital type. During PCM
playback you may select any surround
mode except Dolby Digital.
