OPERATION

internal bass-management system. When this input
is in use, the analog source is converted to digital
so that you may use the same bass-management
options for the direct input as are used for all other
inputs. This input also mutes the unused input jacks
to prevent unwanted noise from interfering with
system performance.

• The

8 CH DIRECT

input should be used

when an input is connected to all eight

8-Channel

Direct Inputs

and when the input source device

has its own internal bass-management system. This
input passes the input from the source directly
through to the volume control without any analog-
to-digital conversion.

• The

8 CH DVD AUDIO

input should be used

when an input is connected to all eight

8-Channel

Direct Inputs

and when the input source does

not have its own internal bass-management system.
When this input is in use, the analog source is con-
verted to digital so that you may use the same
bass-management options for the direct input as
are used for all other inputs.

Volume and Tone Control

• Adjust the volume to a comfortable level using the

front-panel

or remote

Volume

Up/Down Buttons

• To temporarily silence all speaker outputs, press the

Mute Button

. This will interrupt the out-

put to all speakers and the headphone jack, but it
will not affect any recording or dubbing that may be
in progress. When the system is muted, the word

MUTE

will flash in the on-screen display (except

when HDMI, 720p or 1080i sources are in use)
and in the

Upper Display Line

; press the

Mute Buttons

again to return to

normal operation.

• The unit’s tone controls may be taken out of the

signal path by pressing the

Tone Mode Button

. The first button press will show a message

in the on-screen display (except when HDMI, 720p
or 1080i sources are in use) and

Lower Display

Line

with the current status of the tone

controls. The system default is

TONE IN

, which

indicates that the bass and treble controls are active.
Press the

the remote control or the

‹

Buttons

on the

front panel to change the setting to

TONE

OUT

, which is “flat” response without the tone

controls being active.

• When the tone controls are active, the amount of

bass and treble boost/cut may be adjusted up
to ±10dB in 2dB steps by pressing the

Tone

Mode Button

two or three times until the

desired setting (

BASS MODE

TREBLE

MODE

) appears in the on-screen display and in

the

Lower Display Line

. Next, use the

‹

›

Navigation Buttons

on the remote

or the

‹

›

Navigation Buttons

on the front panel

to change the setting as desired. The unit will

return to normal operation within five seconds after
the setting is changed.

• For private listening, simply place a standard

1/4" stereo headphone plug or adapter into the

Headphone Jack

behind the door

on the

front panel. The speakers will automatically mute
and a two-channel stereo signal will be sent to the
headphones. The

Lower Display Line

will read

DOLBY H: BP

, indicating that the headphone

output is in the Bypass mode, and to confirm that
no processing is being used. To listen through the
headphones using the Dolby Headphone mode,
simply press the buttons on the remote or front
panel as shown below for changing a Dolby mode.

DOLBY H: DH

will appear in the Lower

Display Line when the Dolby Headphone mode
is in use.

Surround Mode Selection

One of the most important features of the AVR 445
is its ability to reproduce a full multichannel surround
sound field from digital sources, analog matrix
surround-encoded programs and standard stereo
programs.

Selection of a surround mode is based on personal
taste, as well as the type of program source material
being used. For example, motion pictures or TV pro-
grams bearing the logo of one of the major surround-
encoding processes, such as Dolby Surround or DTS
Stereo may be played in either the Dolby Digital,
Dolby Pro Logic II Cinema, DTS Neo:6 Cinema, or
Logic 7 Cinema surround modes, depending on the
source material.

NOTE:

Once a program has been encoded with matrix

surround information, it retains the surround information
as long as the program is broadcast in stereo. Thus,
movies with surround sound may be decoded via any
of the analog surround modes (e.g., Dolby Pro Logic II
Cinema, Logic 7 Cinema or DTS Neo:6 Cinema) when
they are broadcast via conventional TV stations, cable,
pay-TV and satellite transmission. In addition, a growing
number of made-for-TV programs, sports broadcasts,
radio dramas and music CDs are also produced in sur-
round sound. You may view a list of these programs at
the Dolby Laboratories Web site at www.dolby.com.

Even when a program is not listed as carrying inten-
tional surround information, you may find that the Dolby
Pro Logic II, Dolby Pro Logic IIx, Logic 7 or DTS Neo:6,
and the Hall or Theater modes often deliver enveloping
surround presentations through the use of the natural
information present in all stereo recordings.

Surround modes may be changed at any time by
using either the front panel or remote control. To
select a new surround mode from the front panel, first
press the

Surround Mode Group Selector Button

until the desired major surround mode group such

as Dolby, DTS or Logic 7 is selected. Next, press the

Surround Mode Selector Button

to choose the

specific individual surround mode.

To choose a surround mode using the remote, first
press the button for the major surround mode group
that includes the desired mode. These buttons are the

Dolby Mode Select

, the

DTS Digital Model

Select

, the

DTS Neo:6 Mode Select

, the

DSP Surround Mode Select

and the

Stereo

Mode Select

buttons. The first press of a button

will show the current mode from that group if it is
already in use, or the first available mode if you are
currently using another mode. To cycle through the
available modes in that group, press the button again
until the desired mode appears in the

Lower Display

Line

, the on-screen display (when a 480i source

is in use) and the front-panel

Surround Mode

Indicators

The Dolby Digital, Dolby Digital EX, DTS 5.1, DTS-ES
Matrix and DTS-ES Discrete modes may only be
selected when a digital input is in use. In addition,
when a digital source is present, the AVR 445 will
automatically select and switch to the correct mode,
regardless of the mode that has been previously
selected. For more information on selecting digital
sources, see the Digital Audio Playback section below.

When the 6-channel/8-channel direct inputs are in
use, there is no surround processing, as these inputs
take the analog output signals from an external source
device and carry them straight through to the volume
control without any further digital processing.

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

Stereo Mode Select Button

until

SURROUND OFF

appears in the

Lower Display

Line

. From the front panel, press the

Surround

Mode Group Selector

until the

Stereo

modes

appear in the on-screen display and

Lower Display

Line

. Next, press the

Surround Mode Selector

Button

until

SURROUND OFF

appears in

the on-screen display and

Digital Audio Playback

Digital audio is a major advancement over older analog
surround processing systems. It delivers up to six dis-
crete channels, and each channel reproduces a full-fre-
quency range (20Hz to 20kHz) and offers dramatically
improved dynamic range and significant improvements
to signal-to-noise ratios. In addition, digital systems have
the capability to deliver an additional channel that is
