Enjoying Surround Sound Dynamic range compressor (COMP. D. RANGE xx) 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 want. • MAX provides a dramatic compression of the dynamic range. Note Dynamic range compression does not work with DTS sources. z 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 it provides a very natural compression.
