Hooking Up and Setting Up the Speaker System
x Surround back speaker size
(SURR BACK)
If you connect a large speaker that will
effectively reproduce bass frequencies, select
LARGE. Normally, select LARGE.
However, if the front speakers are set to
SMALL, you cannot set the surround back
speaker to LARGE.
If the sound is distorted, or you feel a lack of
surround effects when using multi channel
surround sound, select SMALL to activate
the bass redirection circuitry and output the
center channel bass frequencies from the front
speakers (if set to LARGE) or sub woofer.
If you do not connect a surround back speaker,
select NO.
Tip
Internally, the LARGE and SMALL settings for each
speaker determine whether or not the internal sound
processor will cut the bass signal from that channel.
When the bass is cut from a channel, the bass
redirection circuitry sends the corresponding bass
frequencies to the sub woofer or other LARGE
speakers.
However, since bass sounds have a certain amount of
directionality, it best not to cut them, if possible.
Therefore, even when using small speakers, you can
set them to LARGE if you want to output the bass
frequencies from that speaker. On the other hand, if
you are using a large speaker, but prefer not to have
bass frequencies output from that speaker, set it to
SMALL.
If the overall sound level is lower than you prefer, set
all speakers to LARGE. If there is not enough bass,
you can use the equalizer to boost the bass levels. To
adjust the equalizer, see page 41.

x Surround back speaker single or
double (SURR BACK L/R)
When the center speaker is set to NO and you
use the center speaker as a surround back right
speaker and use the surround back speaker as a
surround back left speaker, select YES.
If you use only a surround back speaker, select
NO.
x Sub woofer selection (SUB WOOFER)
If you connect a sub woofer, select YES.
If you do not connect a sub woofer, select
NO. This activates the bass redirection
circuitry and outputs the LFE signals from other
speakers.
In order to take full advantage of the Dolby
Digital bass redirection circuitry, we
recommend setting the sub woofers cut off
frequency as high as possible.
x Front speaker distance (FRONT)
Set the distance from your listening position to
the front speakers (A on page 19).
x Center speaker distance (CENTER)
Set the distance from your listening position to
the center speaker. Center speaker distance
should be set from a distance equal to the front
speaker distance (A on page 19) to a distance
1.5 meters closer to your listening position (B
on page 19). When this range is exceeded, the
display blinks. If you make the setting while
the display blinks, you cannot fully enjoy the
surround effect.
