Adjusting the playback volume of Low
Frequency Extension (LFE) signals
encoded on a DVD — LFE MIX
Low Frequency Extension (LFE) signals are a type of
audio signal encoded on a DVD, and reinforce only the
specified bass frequencies at the specified location in
order to provide more real sound effects.
LFE signals can normally be heard from the sub woofer,
but if the sub woofer connection status is set to "NO" by
the speaker settings (see pages 13 and 20), the sound is
output from the front and rear speakers. If you feel the
bass is too strong at this time, perform the following
operations.
Note
LFE signals are a type of DVD audio signal encoded in a specific
location in order to reinforce a specific bass sound. Therefore,
other bass sounds are not reduced even if you adjust the LFE
signal. If you adjust the LFE signal but the bass sounds are still
not reduced, perform one of the following operations.
• When "B.BOOST" is lit in the display, press BASS BOOST so
that "BASS BOOST OFF" appears and "B.BOOST" goes off (see
page 27).
• Adjust "WOOFER" in the LEVEL ADJUST menu to reduce the
sub woofer volume (see page 28).
• Adjust "BASS GAIN" in the EQUALIZER menu (see page 31).
