MAIN MENU
The SUBWOOFER SETUP menu allows selec-
tion of the master subwoofer crossover fre-
quency and independent adjustment of sub-
woofer level for each surround mode.
CROSSOVER (40Hz/60Hz/80Hz/
100Hz/120Hz/150Hz/200Hz/OFF):
This setting specifies a master low-pass filter
for the subwoofer and a corresponding high-
pass filter for all SMALL speakers in the sys-
tem at the selected frequency. To adjust the
crossover frequency, highlight the CROSSOVER
line using the UP/DOWN buttons. Then, use
the +/– buttons to chose the master crossover
point. The 80Hz or 100Hz crossover points
are the most common in home theater systems
and should be used unless you have a spe-
cific reason to choose a different crossover
point based on your specific speakers.
The OFF setting sends a full-range signal to
your subwoofer so that you can use its built-
in low-pass filter. With the OFF setting, a 100
Hz high-pass filter is activated for all SMALL
speakers in the system.
NOTE : The master crossover point can be over-
ridden with a custom crossover frequency for
the front, center, surround, or surround back
speakers in the ADVANCED SPEAKER SETUP
menu; however, in most systems the single
master crossover point should work well

These six lines allow you to override the mas-
ter subwoofer level setting as determined on
the TEST TONE menu (see below) for each
specific surround mode. When going to the
SUBWOOFER SETUP menu from the MAIN
menu, the current surround mode is automati-
cally highlighted. Use the +/– buttons to ad-
just the subwoofer level for the current surround
mode. The options are OFF (which turns off
the subwoofer for that mode) and a range of
adjustments from -9dB to +9dB and MAX
(+10dB). A setting of 0dB means that the speci-
fied surround mode will use the master sub-
woofer level. Any other setting is an offset to
the master setting. For example, an adjustment
of -2db for a particular surround mode means
that the subwoofer level will be 2dB quieter
than the master subwoofer level when that
surround mode is selected. Use these subwoofer
level settings to adjust the relative bass out-
put of various surround modes. Changing the
master subwoofer level will increase or de-
crease the level for all surround modes.
NOTE : Only the current surround mode can
be adjusted on this menu. You will need to
change surround modes using the front panel
or remote buttons to adjust a different mode.
We recommend starting with the settings for
all surround modes at the default 0dB setting
during the test tone calibration of the system
and for a period of familiarization after that.
As you listen to a variety of source material
over time, you may notice that certain surround
modes consistently produce too much or too
little bass from the subwoofer. If so, then use
these menu settings to customize each surround
mode. In general, if the master subwoofer level
is set properly (i.e. not too loud), individual
settings for each surround mode should not
be necessary.
NOTE
: In Dolby Digital and DTS recordings,
the LFE channel is used to produce spectacu-
lar low bass effects, placing considerable de-
mands on your subwoofer system. If you hear
distortion or other signs of distress from your
subwoofer at loud listening levels, you may
consider reducing the subwoofer level for the
Dolby Digital and/or DTS surround modes.
In other surround modes, there is no LFE chan-
nel and the subwoofer will only reproduce
redirected bass from the other channels,
which is not as likely to tax the subwoofer.
To return to the MAIN menu, press the EN-
TER button. Press the MENU/OSD button on
the remote to cancel the display and return
to normal operation.

MAIN MENU
This menu uses filtered pink noise test tones
to set equal volume levels for all speakers (left
front, center, right front, right surround, cen-
ter back, left surround, and subwoofer) to en-
sure proper surround sound reproduction.
Setting the output levels using the test proce-
dure provides the most accurate adjustment
so that digital surround sound material will be
reproduced as it was intended and is a criti-
cal step in calibrating the system.
NOTE : If you have configured your system to
use two center back speakers, there will be
an additional line in the menu, giving you the
ability to independently adjust the CENTER
BACK 1 and CENTER BACK 2 speakers.
To access this menu and perform the test tone
calibration, you can be in any surround mode
except BYPASS with any input except the MULTI
INPUT. Enter the OSD menu system and select
TEST TONE from the MAIN MENU to reach
this screen.
When you enter the TEST TONE menu, you
will hear a test tone coming from the highlighted
speaker. Highlight different speakers by moving
the cursor to the desired line using the UP/
DOWN buttons. The test tone will shift accord-
ingly to the selected speaker.
Seated in the normal listening location, shift
the test tone to the various speakers. Using the
one speaker as a reference, listen for any speak-
ers that are noticeably louder or quieter. If so,
adjust that speaker’s levels up or down (in 1dB
increments) using the +/– buttons. Continue
switching among the speakers and adjusting
until all speakers are the same volume.
To return to the MAIN menu, press the EN-
TER button. Press the MENU/OSD button on
the remote to cancel the menu display and
return to normal operation.
