Basic Operation
2 Dialogue Normalization
Dialogue Normalization (Dial Norm) is a feature of Dolby
Digital, which is used to keep the programs at the same
average listening level so the user does not have to change
the volume control between Dolby Digital programs. When
playing back software which has been encoded in Dolby
Digital, sometimes you may see a brief message in the
front panel display which will read “Dial Norm X dB” (X
being a numeric value). The display is showing how the
program level relates with THX calibration level. If you want
to play the program at calibrated theatrical levels, you may
wish to adjust the volume. For example, if you see the
following message: “Dial Norm + 4 dB” in the front panel
display, to keep the overall output level at THX calibrated
loudness, just turn down the volume control by 4 dB.
However, unlike a movie theater where the playback
loudness is preset, you can choose your preferred volume
setting for best enjoyment.
