is in use, the analog source is converted to digital

ptions for the direct input as are used for all other

nputs. This input also mutes the unused input jacks
to prevent unwanted noise from interfering with
system performance.

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 carr
ying 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
p
ress the
S
urround Mode Group Selector Button
2 u
ntil the desired major surround mode group such
as Dolby, DTS or Logic 7 is selected. Next, press the
Surround Mode Selector Button 3 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 g, the DTS Digital Model
Select
f, the DTS Neo:6 Mode Select e, the
DSP Surround Mode Select 6 and the Stereo
Mode Select
d 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 carr
y 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),

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
