Dialog Normalization - Blu-ray Forum

Gremal · 11-27-2008, 07:37 PM

My Integra AV preamp is automatically making adjustments I don't want it to make. It flashes a sign like "Dialog Norm +4" when I switch to a different channel or source and I really don't want it making automatic adjustments like this. I can't remember turning on the dialog normalization function and after going through the entire instruction manual, I can't figure out how to turn it off.

Any help would be greatly appreciated. The model is the DTC-9.8

what is the source of audio? dolby digital?

I don't think it can be turned off, my Denon receiver also displays it. From a Yamaha manual:

"Dialogue Normalization is a feature of Dolby Digital or DTS, which is used to keep the programs at the same average listening level so that the user does not have to change the volume control between Dolby Digital or DTS programs."

It is not the same as "dynamic range control". Dialogue Normalization only affects the overall volume level, kinda like turning the volume up or down. It's coded as metadata in the stream and tells the decoder at what level the dialog is.

Read the article Dialogue Normalization: Friend or Foe and you will find that dialog normalization is not a bad thing.

Ok, thanks...it's not user adjustable. I need to stop obsessing over it.

Give them a call, maybe they have newer firmware that lets the user decide to have it on or off.

After googling around, I think it was developed to automatically level-match between different DD and DTS sources.
