x L.F.E. XXX.X dB
(LFE (Low Frequency Effect) mix level)
Initial setting: 0 dB
Lets you attenuate the level of the LFE (Low
Frequency Effect) channel output from the sub
woofer without effecting the level of the bass
frequencies sent to the sub woofer from the front,
center or surround channels via the Dolby Digital or
DTS bass redirection circuitry. You can adjust from
–20 dB to 0 dB (line level) in 0.5 dB steps. "0 dB"
outputs the full LFE signal at the mix level
determined by the recording engineer. When set to
"OFF", the sound of the LFE channel from the sub
woofer is muted. In this case, the low frequency
sounds of the front, center, or surround speakers are
output from the sub woofer according to the settings
made for each speaker (pages 21–22).
x COMP. (
D.RANGE
(Dynamic range compressor)
Lets you compress the dynamic range of the sound
track. This may be useful when you want to watch
movies at low volumes late at night.
• OFF
The dynamic range is not compressed.
• 0.1–0.9
The dynamic range is compressed in small steps to
achieve the sound you desire.
• STD
The dynamic range is compressed as intended by
the recording engineer.
• MAX
The dynamic range is compressed dramatically.
Tip
Dynamic range compressor lets you to compress the
dynamic range of the soundtrack based on the
dynamic range information included in the Dolby
Digital signal. "STD" is standard compression, but
because many sources have only light compression,
you may not notice much difference when using 0.1–
0.9.
Therefore, we recommend using the "MAX" setting.
This greatly compresses the dynamic range and lets
you view movies late at night at low volumes. Unlike
analog limiters, the levels are predetermined and
provide a very natural compression.
Note
Dynamic range compression is possible with Dolby
Digital sources only.
