2. This Dynamic Range Compression section only applies to
DVD-titles with Dolby Digital technology.
• Select the Quiet Environment if you are in the mood to
watch a movie without distractions. All audible sound, from
low frequency to high frequency audio effects, will be highly
distinctive and fall into the full dynamic range of Dolby
Digital.
• If your listening environment is not completely adequate to
enjoy the full dynamic range of Dolby Digital, select the
Normal Environment. Audible effects that fall in the extreme
ranges of Dolby Digital’s audio spectrum will be compressed.
• If you are using PowerDVD on a notebook or laptop, the last
selection is for you. In a Noisy Environment, low range
audio signals will be amplified so that the audible volume
will be increased.
3. If you wish to elevate your bass or Low Frequency Effect (LFE),
check Enable. This option will enhance the LFE effects of your
Dolby Digital/DTS-enhanced DVD titles and is recommended
for headphones, 2-, and 4-speaker systems.
