Subwoofer
– LFE signals and bass frequencies of
channels set to
SMALL
are output from the
subwoofer when
YES
is selected. Choose the
PLUS
setting if you want the subwoofer to output bass
sound continuously or you want deeper bass (the
bass frequencies that would normally come out the
front and center speakers are also routed to the
subwoofer).
1
If you did not connect a subwoofer
choose
NO
(the bass frequencies are output from
other speakers).

Tip
• The channel level can be changed at any time. Press
RECEIVER
then press
CH LEVEL
on the remote
control, and then use
/
to adjust the level.
Speaker Distance
For good sound depth and separation from your system,
you need to specify the distance of your speakers from
the listening position. The receiver can then add the
proper delay needed for effective surround sound.
Note
1 If you have a subwoofer and like lots of bass, it may seem logical to select
LARGE
for your front speakers and
PLUS
for the subwoofer. This may not,
however, yield the best bass results. Depending on the speaker placement of your room you may actually experience a decrease in the amount of bass due
low frequency cancellations. In this case, try changing the position or direction of speakers. If you can’t get good results, listen to the bass response with
it set to
PLUS
and
YES
or the front speakers set to
LARGE
and
SMALL
alternatively and let your ears judge which sounds best. If you’re having problems,
the easiest option is to route all the bass sounds to the subwoofer by selecting
SMALL
for the front speakers.
2• This setting decides the cutoff between bass sounds playing back from the speakers selected as
LARGE
, or the subwoofer, and bass sounds playing
back from those selected as
SMALL
. It also decides where the cutoff will be for bass sounds in the LFE channel.
• If you’re using a THX speaker setup, confirm that the crossover frequency is set to
80Hz
.
