18 SYSTEM CONFIGURATION
System Configuration
to digital sources. In the case of inputs such as a
CD Player, Tape Deck or Tuner, you may wish to
set the mode to Stereo, if that is your preferred
listening mode for standard stereo sources, where
it is unlikely that surround encoded material will
be used. Alternatively, the 5 Channel Stereo or
Logic 7 Music mode may also be a good choice
for stereo-only source material.
It is easiest to complete the surround setup using
the full-OSD on-screen menus. From the
MASTER menu (Figure 1), press the ⁄ / ¤
buttons D until the ➞ cursor is next to the
SURROUND SELECT menu. Press the
Set Button F so that the
SURROUND
SELECT menu (Figure 3) is on the screen.
Figure 3
Each of the option lines on this menu (Figure 3)
selects the surround mode category, and within
each of those categories there will be a choice of
the specific mode options. The choice of modes
will vary according to the speaker configuration
in your system.
When the SURR BACK line of the
SPEAKER SETUP menu (Figure 7) is set to
NONE the AVR will be configured for
5.1-channel operation, and only the modes
appropriate to a five-speaker system will appear.
When the SURR BACK line of the SPEAK-
E R SETUP menu (Figure 7) is set to SMALL
or LARGE the AVR will be configured for
6.1/7.1-channel operation, and additional modes
such as Dolby Digital EX and 7 STEREO or Logic 7
7.1 will appear. In addition, the modes DTS ES
(Discrete) and DTS+NEO:6 (DTS ES Matrix) avail-
able in the AVR 140 will not appear unless a digi-
tal source is playing the correct bitstream.
In addition, some of the modes available in the
AVR will not appear unless a digital source is
selected and is playing the correct bitstream.
Remember that when you use only a single, sur-
round back speaker, you will get the benefits of a
6.1/7.1 system, but with only one speaker
installed at the back of the room. The mode indi-
cations will show 7.1 in some cases, but no addi-
tional adjustment is needed for 6.1 operation.
Remember that the AVR will combine the left and
right surround back channel information present
in 7.1 modes such as Logic 7/7.1 and 7-channel
stereo, outputting the information as a single sur-
round back channel.
Note: When a Dolby Digital or DTS source is
selected and playing, the AVR will select the
appropriate surround mode automatically, no
matter which surround mode was selected for
that input as default. Then no other surround
modes will be available, except VMAx with Dolby
Digital recordings and all Pro Logic II modes with
Dolby Digital 2 channel (2.0) recordings (see
page 29).
To select the mode that will be used as the initial
default for an input, first press the
⁄ / ¤ buttons
D until the on-screen cursor is next to the
desired mode’s master category name. Next,
press the Set Button
F to view the sub-
menu. Press the ‹ / › Buttons Ea to scroll
through the available choices, and then press the
¤ Button D so that the cursor is next to
BACK TO MASTER MENU to continue the
setup process.
On the DOLBY SURROUND menu (Figure
4), the selection choices include Dolby Digital,
Dolby Pro Logic II or llx Music, Dolby Pro Logic II
or llx Cinema, Dolby Pro Logic II and Dolby 3
Stereo. The Dolby Digital EX and Dolby Pro Logic
IIx modes are only available when the system is
set for 6.1/7.1 operation by configuring the
Surround Back speakers to “Small” or “Large” as
described on page 21. When a disc is playing that
contains a special “flag” signal in the digital
audio data stream, the EX mode will be selected
automatically. It may also be selected using this
menu or through the front panel or remote con-
trols as shown on page 29. A complete explana-
tion of these modes is found on Page 26-27.
Note that when the Dolby Digital mode is select-
ed there are additional settings available for the
Night mode that are associated with the sur-
round mode only, not with the input. That´s why
these settings must be made only once, not with
each input in use. They are described later in the
next main chapter (see below).
Figure 4
When the ➞ cursor is pointing to the
MODE
line, press the ‹ / › Navigation Buttons
Ea to select the desired Dolby surround
mode, again remembering that the choice of
available modes will vary with the type of pro-
gram material being played and the number of
speakers in your system configuratioin.
When Dolby Pro Logic II Music or Dolby Pro Logic
IIx Music is selected as the listening mode, three
special settings are available to tailor the sound
field to your listening room environment and your
individual taste and preferences. (When other
Dolby Surround modes are selected, dotted lines
will indicate that these settings are not active.)
• Center Width: This setting adjusts the balance
of the vocal information in the front sound-
stage between the center and front left/right
speakers. The lower settings spread the center
channel sound more broadly into the left and
right channels. A higher number (up to “7”)
produces a tighter center channel presenta-
tioin.
• Dimension: This setting alters the perceived
depth of the surround field by creating a shal-
lower presentation that appears to move
sounds toward the front of the room, or a
deeper presentation that appears to move the
center of the sound field toward the back of
the room. The setting of “O” is a neutral
default, with the range of adjustment shown as
“R-3” for a deeper, rear-oriented sound to
“F-3” for a shallower, front-oriented sound.
• Panorama: Switch this setting on or off to add
an enveloping wrap-around presentation that
increases the perception of sound along the
sides of the room.
To change these parameters, press the ⁄ / ¤
Navigation Buttons D while the
DOLBY
SURROUND menu is on the screen until the
➞ cursor is pointing to the line on the menu with
the parameter you wish to change. Then, press
the
‹ / › Navigation Buttons Ea to alter
the setting to your taste.
Note that when the Dolby Digital mode is select-
ed there are additional settings available for the
Night mode that are associated with the sur-
round mode only, not with the input. That´s why
these settings must be made only once, not with
each input in use.
Night Mode Settings
The Night mode is a feature of Dolby Digital that
uses special processing to preserve the dynamic
range and full intelligibility of a movie sound track
while reducing the peak level. This prevents
abruptly loud transitions from disturbing others,
without reducing the sonic impact of a digital
source. Note that the Night mode is only available
when the Dolby Digital surround mode is select-
ed.
To adjust the Night mode setting from the menu
press the OSD Button
L so that the
MASTER menu appears. Then press the ¤
button D to access the
AUDIO SETUP and
press Set F to select the
SURROUND
SETUP menu. Press Set F to select the
DOLBY menu (see fig. 5).
