as doing so may damage your speakers, the
AVR 135 or both.When 7.1-channel information is
received, for example through the
Direct Inputs
f, or when deriving 7-Channel Stereo
or Logic 7/7.1 surround infor
mation, the AVR 135
combines the left and right surround back channel
information and outputs it as a single surround back
When you have completed your selection for the back
surround channels, press the
Button n on the
remote to move the cursor to
Press the
Buttons oon the remote to select
the option that best describes your system.
The choices available for the subwoofer position will
depend on the settings for the other speakers, particu-
larly the front left/right positions.
If the front left/right speakers are set to
the subwoofer will automatically be set to
which is the “on” position.
If the front left/right speakers are set to
three options are available:
• If no subwoofer is connected to the AVR 135,
press the
Buttons o on the remote so
NONE appears in the on-screen menu.
When this option is selected, all bass information
will be routed to the front left/right “main” speakers.
• If a subwoofer is connected and you wish to have
the front left/right “main” speakers reproduce bass
frequencies at all times
, and have the subwoofer
operate only when the
VR 135 is being used
with a digital source that contains a dedicated
Low-Frequency Effects, or LFE, soundtrack. Press
Buttons o on the remote so that
LFE appears in the on-screen menu.
• If a subwoofer is connected and you wish to use it
for bass reproduction in conjunction with the main
front left/right speakers, regardless of the type of
program source or Surround mode, press the
Buttons o on the remote so that SUB
appears in the on-screen menu.
When this option is selected, a full-range signal
will be sent to the front left/right “main” speakers,
and the subwoofer will receive the bass frequen-
cies under frequency selected,
as described
below, as well as the LFE information.
When all initial speaker “size” settings have been
, you now have the option to take advantage of
the AVR 135’s Triple Crossover system, which allows
individual crossover settings to be made for each
speaker grouping
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 defined as the lowest possible frequency
the speaker is capable of reproducing. 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 three groupings, front
left/right, center and surrounds, by looking at the
specifications page of each speakers’ owner’s manual,
or by contacting your dealer
or the manufacturer’s
customer service department or Web site. You will
need this figure to accurately configure the next group
of settings.
The factor
y default setting for all speaker positions is
100Hz. If that setting is acceptable for all channels,
then no adjustments are needed and you may skip
this section.
However, should you wish to change one
of the settings, please proceed by pressing the
Button n so that the cursor moves back up to the
top of the list of setting options. Press the
Buttons n so that X-OVER is highlighted and
the menu data will change to the screen shown in
Figure 6.
Figure 6
To change the setting for any of the three speaker
press the
Buttons n until the cursor
is next to the line where you wish to make a change
and then press the
Buttons o until the
desired setting appears.The available choices at which
point low-frequency infor
mation will be sent to the
, rather than to the main speaker channel,
are 40Hz, 60Hz, 80Hz, 100Hz, 120Hz and 200Hz.
Pick the choice that is identical to the information for
the 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 creation
of a low-frequency “hole” where your system will have
no bass information.
In cases where
LARGE has been selected as the
front-channel speaker option and
LFE+L/R has
been selected as the subwoofer option, the front-
channel sound infor
mation below the setting shown
will be sent to BOTH the front-channel speakers and
the subwoofer
Note, also, that when the
setting has been selected, the
crossover point is set by making adjustments at the
SUBWOOFER line, but the setting for the front
left/right speakers will automatically change in tandem
so that the same setting appears for both speaker
positions.This ensures that there is no “hole” in the
sound field due to different crossover points at the
front and subwoofer speakers
When all crossover settings have been made, or in
those cases where none are needed,
press the
Button n so that the cursor is next to the BASS
line to make the final setting on this menu.
This setting allows you to use the same speaker size
configuration for all inputs
, or to have different settings
for each input. In most cases the factory default set-
ting of
GLOBAL will be appropriate, as most lis-
teners do not need to have individualized settings.
However, some listeners, particularly those with full-
range front speakers that are used for both movies
and music, may prefer that different bass management
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.
If you wish to customize the speaker settings for
each input, make certain that the
MODE line of
SPEAKER SETUP menu is set to
SIZE, and that the cursor is on the BASS
line, and press the
Buttons o so that
INDEPENDENT appears.When this setting is
entered by exiting the menu, you may need to go
back to the
INPUT menu to select another input,
and then return to this menu page again to change
the settings for that input. Repeat the procedure for
any input where you wish to have a different set of
speaker configurations.
NOTE: When the INDEPENDENT setting is
you may assign different speaker size set
tings to each input to accommodate different bass
management settings that match your preferences
with the type of program material normally used with a
particular source (for example
when movies are played
from DVD and music from a CD player). However, the
actual speaker crossover settings are set only once and
do not change with the input selection.
The reason is
that, while bass management preferences may vary,
the actual speakers remain the same
regardless of the
bass-management and redirection settings.
When all speaker selections have been made
Button n and then the Set Button p to
return to the
Delay Settings
Due to the different distances between the listening
position for the front channel speakers and the sur-
round speakers, the amount of time it takes for sound
to reach your ears from the front versus surround
speakers differs
You may compensate for this differ-
