x SURROUND (
SL
SR
)
(Surround speaker size)
LARGE
If you connect large speakers 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
speakers to LARGE.
SMALL
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
surround channel bass frequencies from the sub
woofer or other LARGE speakers.
NO
If you did not connect surround speakers, select
NO.
Tip
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 has 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 39.
x SUB WOOFER (
SW
)
(Sub woofer selection)
YES
If you connect a sub woofer, select YES.
NO
If you did not connect a sub woofer, select
NO. This activates the bass redirection
circuitry and outputs the LFE signals from other
speakers.
Tip
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.
For advanced speaker setups
Use the CUSTOMIZE menu and set MENU
to MENU EXP. This enables advanced
setups including those of the distances to the
speakers and heights of the speakers.
For details on MENU, see page 40. For
details on how to set the items, see page 41.
