signals will be sent to the subwoofer output.
When
NONE
is selected, surround
sound information will be split between
the front left and front right outputs. For
optimal performance when no surround
speakers are in use, the Dolby 3 Stereo
mode should be used.
When you have completed your selec-
tions for the side surround channels,
press the
⁄

q
to move the cursor to
BACK
SURROUNDS
. Press the
‹
/
›
Navigation Controls
q
to select
the option that best describes the speakers
in use at the left and right back surround
positions based on these definitions:
When
NONE
is selected, the system
will adjust so that only 5.1-channel sur-
round processing/decoding modes are
available and the surround back amplifier
channels will not be used. This setting will
override any setting made previously in
the
SYSTEM CONFIGURATION
submenu (Figure 7).
When
SMALL
is selected, the system
will adjust so that the full complement of
6.1/7.1 surround processing/ decoding
modes are available, and low-frequency
information below the crossover point
will be sent to the subwoofer output. If
you choose this option and there is no
subwoofer connected, you will not hear
any low-frequency sounds from the sur-
round back channels.
When
LARGE
is selected, the system
will adjust so that the full complement
of 6.1/7.1 surround processing/decoding
modes are available, and a full-range
signal will be sent to the surround back
channels, with no low-frequency informa-
tion sent to the subwoofer output.
When you have completed your selection
for the back surround channels, press the
⁄

Navigation Controls
q
to move the cursor to
SUBWOOFER
.
Press the
‹
/
›
Navigation Controls
q
to select the option that best
describes your system. The choices avail-
able for the subwoofer position will
depend on the settings for the other
speakers, particularly the front left/right
positions. If the front left/right speakers
are set to
SMALL
, the subwoofer will
automatically be set to
ON
. If the front
left/right speakers are set to
LARGE
,
two options are available:
• If no subwoofer is connected to the
CVR700, press the
‹
/
›
Navigation
Controls
q
so that
OFF
appears in the on-screen menu. When
this option is selected, all bass infor-
mation will be routed to the front
left/right “main” speakers.
• If a subwoofer is connected to the
CVR700, you have the option to have
the front left/right “main” speakers
reproduce bass frequencies at all
times, and have the subwoofer operate
only when the CVR700 is being used
with a digital source that contains a
dedicated low-frequency effects, or LFE
soundtrack. This allows you to use both
your main and subwoofer speakers to
take advantage of the special bass
sounds created for some movies. Note,
however, that the subwoofer will only
play the LFE information. Press the
‹
/
›
Navigation Controls
q
so that
ON
appears in the on-screen
menu.
The
BASS MGR
setting allows you to
use the same speaker configuration set-
tings for all inputs, or to have different
settings for each input. In most cases, the
factory default setting of
GLOBAL
will
be appropriate, as most listeners do not
need to have individualized speaker set-
tings. However, some listeners, particu-
larly those with full-range front speakers
that are used for both movies and music,
may prefer that different bass manage-
ment settings be used when listening to
music through a CD player as opposed
to a movie from a DVD player, VCR or
cable/satellite set-top.
Use the
‹
/
›
Navigation Controls
q
to change this setting to
INDEPENDENT
. You may now
change the source input and return to the
SPEAKER CONFIGURATION
menu and adjust the speaker sizes to suit
the source.
Speaker Crossover
Configuration
When all initial speaker “size” settings
have been made, you now have the
option to take advantage of the CVR700’s
Quadruple Crossover system, which
allows individual crossover settings to be
made for each speaker grouping. Again,
if you are using JBL Cinema Vision loud-
speakers, you may skip this submenu, as
the factory default settings are appropri-
ate for your speakers.
The low-frequency crossover point is set
by the design of your speakers. Depending
on the design and driver complement of
your speakers, it is usually the lowest
possible frequency the speaker is capable
of reproducing, but it may be different for
speakers that include a powered woofer
section intended to reproduce the LFE
channel. Before making any changes to
the settings for the crossover point, we
suggest that you find the crossover point
for the speakers in each of the four
groupings, front left/right, center front,
side surround and back surround, by look-
ing at the specifications page of each
speaker’s owner’s manual, by getting that
information from the manufacturer’s Web
site, or by contacting your dealer or the
manufacturer’s customer service depart-
ment. You will need this figure to accu-
rately configure the next group of settings.
Note that when any speaker group other
than the front left/right speakers is set to
LARGE
, the crossover may not be
adjusted, as the feed will be full-range,
with no sound being derived for the sub-
woofer at that position. The factory
default setting for all speaker positions
is 90Hz. To change one of the settings,
return to the
SPEAKERS
submenu
(Figure 20), and then scroll to the
CROSSOVERS
line and select it.
The
SPEAKER CROSSOVERS
submenu (Figure 22) will be displayed.
To change the setting for any of the
four speaker groups, press the
⁄
/
¤
Navigation Controls
q
until the
cursor is next to the speaker group where
you wish to make a change and then
press the
‹
/
›
Navigation Controls
q
until the desired setting
appears. The available choices for low-
frequency information to be sent to the
subwoofer, rather than to the main
speaker channel, are 40Hz, 60Hz, 80Hz,
90Hz, 100Hz, 120Hz and 200Hz. Pick the
choice that is identical to the information
for your speakers, or if an exact match is
not possible, pick the closest choice that
is ABOVE the speaker’s low-frequency
limit or crossover point to avoid the cre-
ation of a low-frequency “hole” where
your system will have no bass informa-
tion. The setting for the crossover point
for the LFE channel, which is created to
provide specific low-frequency informa-
tion in many movies with digital sound-
tracks, may be set to match the cross-
over for any of the four speaker groups.
Since the crossover point commonly
used in the creation of the LFE channel
SUBWOOFER
is 120Hz, we recom-
mend that you select the speaker group
whose crossover point is closest to
120Hz. To do this, press the
