Basic operations
Adjusting the bass/treble
sound
You can adjust each enhancement level from the front speakers
within the range from –10 to +10.
On the remote control:
Press BASS +/– for bass sound.
Press TREBLE +/– for treble sound.
NOTE
• You can also make adjustments using the choice menu shown on the
TV screen. (A pg. 49)
• The adjustments on a source take effect for the other sources.
• You can adjust bass/treble enhancement level only for front left/right
channel. However, the supplied speakers cannot add the effective
change to the bass sound because of their cutoff frequency even if the
bass sound adjustment is made. (A pg. 50)
To change the bass enhancement level more efficiently, adjust the
output level of the subwoofer. (A "Adjusting the output level of the
subwoofer")
(When you change the front speakers to the larger ones and select
"LARGE" for the front speakers in the SIZE sub-menu (A pg. 50),
the effective adjustment of bass sound is also possible by pressing
BASS +/–.)
