maybe it is turned on by default.
supposedly it makes dialogue heard clearly over louder action sounds.
but it achieves this by compressing the entire sound track - that's why on your BD player, louder sounds are not that louder, and lower level details are heard more easily.
there's a catch of course. poorer sound fidelity overall....
You probably meant Dynamic Range Control , but just in case, Dolby's license now forbits all CE equipment from having access to altering the Dialog Normalization feature. Most soundtracks on DVD and Blu-ray use about 4dB of normalization (should show up as -4dB) when a Dolby soundtrack is being played. This is the default setting for the Dolby encoder: the audio engineer has to program the encoder to disable normalization if he doesn't want to use it. Dolby's implementation is ass-backwards.
Years ago, a few manufacturers actually had receivers/processors that allowed an adjustment to be made to Dialog Normalization. Dolby didn't appreciate this work-around and added the clause that, to be certified by Dolby and obtain a license, CE products must not alter Dialog Normalization coefficients. The normalization data presides in the metadata of the stream. There is a member at AVS Forum who states that his computer software player allows him to disable Dialog Normalization, so perhaps there is a work-around for this unneeded feature that Dolby has dumped on consumers.
