5. OPERATIONAL
To simplify the implementation of dialogue normalization, dynamic range control, and downmixing, Dolby Digital decoder
implementations offer standard operational modes called Line Mode and RF Mode. There are 2 values for OPERATIONAL. They
are Line Mode and RF Mode. Choose Line Mode when connecting to an amplifier, RF Mode for TV via ANTENNA.
6. DYNAMIC RNG (Valid for Dolby Digital DVD disc)
A consistent problem in the delivery of audio programming is that different members of the audience desire or even need different
amounts of dynamic range depending on the listening situation. Original high quality programs, such as feature films, are typically
mixed with a wide dynamic range. Using dialogue as a reference, loud sounds like explosions are often 20 dB louder, and faint
sounds like leaves rustling may be 50 dB quieter. In many listening situations, it is objectionable to allow the sound to become
very loud, and the loudest sounds must be compressed downwards in level. Likewise the very quiet sounds would be inaudible
and must be brought upwards in level to be heard. If you want to hear the original dynamic range recorded on disc set the
DYNAMIC RNG to 0. Otherwise set to 8 then the dynamic range is reduced by bringing down the level of the loud sounds and
bringing up the level of the quiet sounds.
