The warning message will remain for four
seconds and then the
menu will return to the screen. At this point you
may change the settings to the "size" or
crossover for any of the four speaker positions
using the Navigation Buttons
above. The information below details the settings
available for each of the speaker configurations.
At each of the four speaker position lines, you
have the option to set the speaker size and
crossover. Note that the "size" does not refer to
the speaker's actual physical size, but rather to
the ability of the speaker to reproduce low-fre-
quency information. If your speakers at any
position are traditional full-range models capable
line and of handling the full audio spectrum, select
. These speakers are called "large"
LARGE
since the low-frequency drivers required to play
bass without strain or distortion are typically
eight to fifteen inches in diameter, in turn making
the speaker cabinet larger than those with small
(or no) low-frequency drivers. When the speakers
at a particular position are smaller frequency-
limited speakers that do not have the ability to
properly reproduce low-frequency sounds, select
.

This setting tells the system that no speakers are
present at that position, allowing the AVR to
select the correct surround modes that are com-
patible with the number of speakers installed. For

and "7 Stereo" modes, you must have either

except the front left/right, when

"small" speaker, choose the setting that has the
frequency closest to that of the lowest frequency

not match, select the one that is above, but
closest to, the speaker's low-frequency limit.

to these channels will be split between the front
left and right speakers. Note that when your
system does not include Center or Surround
speakers, the use of Dolby Virtual Speaker as a
surround mode may provide a sound field that
simulates the presence of these speakers. (See

room. See page 33 for more information on
amplifier configuration.)
