Dolby Pro Logic ON/OFF :
Dolby Pro Logic is a matrix decoder that decodes the four channels of surround sound that have
been encoded onto the stereo soundtracks of Dolby Surround program material such as VHS movies
and TV shows. Dolby Surround is a matrix encoding process that in essence "folds" Left, Center,
Right, and Surround channels onto stereo soundtracks.
A Pro Logic decoder "unfolds" the four channels on playback (without a Pro Logic decoder,
the encoded program plays in regular stereo).
DRC (Dynamic Range Compression) ON/OFF :
Allows you to enjoy a powerful sound even at a low volume level.
This provides a reduction in the dynamic range of the reproduced audio for listening conditions such
as ambient noise problems, late night listening, etc, by cutting the level of audio range that falls
above the dialog area (louder sounds) and by boosting the level of audio range that falls below the
dialog are (quieter sounds).
However, some program materials with an already restricted dynamic range, whether inherent or
because of prior processing, lies primarily within the null band and hence is not subjected to further
compression.
Rear Delay :
Allows you to adjust the rear delay setting from 0msec to 15msec in 5msec interval.
The delay time setting is essential for an optimal surround sound, regardless of the surround sound
format (Dolby Surround, Dolby Digital or DTS).
A proper delay time compensates the fact that one speaker is closer to the listener than another.
The use of the proper delay time results in sounds panning from front to back in a smooth and
natural way and avoids distracting sounds from the rear to keep your attention out from the action
of the movie.
Channel Level :
The loudness level can be adjusted between -10dB to +10dB in -1dB increments for each channel.
A setting of 0 dB is recommended for optimum performance; however, if the low frequency range is
too strong, for example, lower the subwoofer level as necessary.
