Settings and Adjustments p dts LFE (Low Frequency Effect) mix level dts LFE MIX XX.XdB Initial setting : 0 dB This parameter 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 rear channels via the "dts" bass redirection circuitry. • The level can be adjusted in 0.5 dB steps from +10.0 dB to -20.0 dB (line level). • Selecting OFF mutes the sound of the LFE channel from the sub woofer. However, the low frequency sounds of the front, center, or rear speakers are output from the sub woofer according to the settings made for each speaker in the speaker setup (page 18~21). z 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. This is because there is an initial difference of 10 dB in the overall mix between the Dolby Digital and dts LFE channel levels. Essentially, with the "dts LFE MIX" level set to +10 dB and the "LFE MIX (Dolby Digital)" level set to 0 dB, approximately the same amounts of LFE channel signal are distributed to the other audio channels in the overall mix. p Dynamic range compressor D. RANGE COMP [OFF] 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. • 0.1 ~ 0.9 allow you to compress the dynamic range in small steps to achieve the sound you desire. • STD reproduces the sound track with the dynamic range intended by the recording engineer. • MAX provides a dramatic compression of the dynamic range. Note Dynamic range compression is only possible with Dolby Digital 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 provide a very natural compression. p Muting MUTING [OFF] Initial setting : OFF Lets you mute the sound (same as MUTING on the remote). • ON to mutes the sound from all speakers. • OFF restores the sound to the original volume. 43
