Amplifier Operations
x CNT SPK (Center speaker)
•LARGE
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
center speaker 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
center channel bass frequencies from the
front speakers (if set to “LARGE”) or sub
woofer.
• NO
If you have not connected a center speaker,
select “NO”. The sound of the center
channel will be output from the front
speakers.
x SUR SPK (Surround speakers)
•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 have not connected surround
speakers, select “NO”.
Tip
The “LARGE” and “SMALL” settings for each
speaker determine whether 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 is 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 tone to boost the bass levels.
For details, see page 33.
x FRT DIST. (Front speaker
distance)
Lets you set the distance from your listening
position to the front speakers (A). If both
front speakers are not placed an equal distance
from your listening position, set the distance as
the average distance between the front
speakers.
x CNT DIST. (Center speaker
distance)
Lets you 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) to a distance
1.5 meters closer to your listening position
(B).
