About the level differences in the LFE MIX settings
The "dts LFE MIX" level is set to +10.0 dB and "LFE MIX" (Dolby
Digital) is set to 0 dB.
Dynamic range compressor (D. RANGE COMP)
Initial setting : OFF
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.

About the Dynamic Range Compressor
This parameter allows 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 allows you to view movies
late at night at low volumes. Unlike analog limiters, the levels are
predetermined and provide a very natural compression.
