Customizing sound fields (continued)
x LFE (Low Frequency Effect) mix level
(LFE)
Lets you attenuate the level of the LFE (Low
Frequency Effect) channel output from the
subwoofer without effecting the level of the
bass frequencies sent to the subwoofer from the
front, center or rear channels via the Dolby
Digital bass redirection circuitry.
• "0 dB" outputs the full LFE signal at the mix
level determined by the recording engineer.
• "MUTING" mutes the sound of the LFE
channel from the subwoofer. However, the low
frequency sounds of the front, center, or rear
speakers are output from the subwoofer
according to the settings made for each speaker
in the speaker setup (page 14).
x Dynamic range compressor (D.COMP.)
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" reproduces the sound track with no
compression.
• "STD" reproduces the sound track with the
dynamic range intended by the recording
engineer.
• "0.1" – "0.9" allow you to compress the
dynamic range in small steps to achieve the
sound you desire.
• "MAX" provides a dramatic compression of the
dynamic range.
Note
Dynamic range compression is possible with Dolby
Digital sources only.
