Although personal preference is the ultimate
guide, you typically increase the delay to speak-
ers located closer to the seating area and de-
crease the delay to speakers located farther
from the seating area.
Start by measuring the distance from your
seating position to each speaker. The speaker
farthest away should receive no additional
delay. Each of the other speakers will receive
one millisecond of delay for each foot (30 cm)
closer to you than the farthest speaker. For ex-
ample, if the left front speaker is farthest away
at 13 feet and the left rear speaker is 8 feet
away, you should add 5 milliseconds of de-
lay to the left rear speaker. Continue setting
delays for each speaker until you have com-
pensated for each speaker that is closer to you
than the farthest speaker.
The delay times for the surround speakers are
set longer for Dolby Pro Logic II mode than in
Dolby Digital/DTS mode. When you change
delay setting for Dolby Digital/DTS, the de-
lay time for Dolby Pro Logic II will automati-
cally be set for MUSIC or CINEMA/EMULA-
TION modes.
The available settings for the CENTER chan-
nel (Dolby Digital/DTS only) are 0ms, 1ms,
2ms, 3ms, 4ms, and 5ms. For SURROUND
(Dolby Digital/DTS), the settings are 0ms, 5ms,
10ms, and 15ms. For SURROUND (Dolby Pro
Logic II), the MUSIC mode settings are the same
as the Dolby Digital/DTS settings. For SUR-
ROUND (Dolby Pro Logic II), the CINEMA/
EMULATION mode settings are 10ms, 15ms,
20ms, and 25ms. For the CENTER BACK
channel (Dolby Digital/DTS only), the settings
are 0ms, 5ms, 10ms, and 15ms.
To change a setting, place the highlight on the
desired line using the UP/DOWN buttons and
use the +/– buttons to increase or decrease
the delay setting. To return to the MAIN menu,
press the ENTER button. Press the MENU key
on the remote to cancel the display and re-
turn to normal operation.
SUBWOOFER SETUP Menu
SUB SETUP
CROSSOVER: 100HZ
DOLBY: 0dB
DTS: 0dB
STEREO: 0dB
MUSIC: 0dB
MULTI INPUT: 0dB
ENT KEY=MAIN MENU UP KEY=up
+/– KEY=change DWN KEY=down
The SUBWOOFER SETUP menu allows selec-
tion of the subwoofer crossover frequency and
independent adjustment of subwoofer level for
each surround mode. These settings are memo-
rized and engaged automatically each time
a music or theater surround mode is selected.
When going to the SUBWOOFER SETUP menu
from the MAIN menu, the current surround
mode is automatically highlighted. Use the +/–
buttons to adjust the subwoofer level (–10dB
to +10dB) for the current surround mode.
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 level settings
for all surround modes at the default 0 dB 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. Use these sub-
woofer level settings to adjust the relative bass
output of various surround modes.
NOTE
: In Dolby Digital and DTS recordings,
the LFE channel is used to produce spectacu-
lar low bass effects. This LFE channel can
generate output 10 dB louder than the other
channels, placing considerable demands on
your subwoofer system. If you hear distortion
or other signs of distress from your subwoofer
at loud listening levels, you may consider re-
ducing the subwoofer level for the Dolby Digi-
tal and/or DTS surround modes. In other
surround modes, there is no LFE channel and
the subwoofer will only reproduce redirected
bass from the other channels, which is not as
likely to tax the subwoofer.
The CROSSOVER setting activates a low-pass
filter for the subwoofer and a corresponding
high-pass filter for all SMALL speakers in the
system at the selected frequency. To adjust the
crossover frequency, highlight the CROSSOVER
line using the UP/DOWN buttons. Then, use
the +/– buttons to chose one of the following
options: OFF, 40Hz, 60Hz, 80Hz, 100Hz,
or 120Hz. The 80Hz or 100Hz crossover
points are the most common in home theater
systems. However, your best setting depends
on the specific speakers in your system.
NOTE : The OFF setting sends a full-range sig-
nal 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.
To return to the MAIN menu, press the EN-
TER button. Press the MENU key on the remote
to cancel the display and return to normal
operation.
