Information
Dialog Normalization
Dialog Normalization (DialogNorm) is one of the Dolby
Digital features that can stabilize the average volume
level between the Dolby Digital, Dolby Digital Plus and
Dolby TrueHD sources, eliminating the need to adjust
the volume for each user or source. "DialogNorm: X dB"
("X" is a numerical value) may appear on the unit display
when a Dolby Digital, Dolby Digital Plus or Dolby TrueHD
source is played. It indicates the relation between the
source's volume level and the THX standard level. If
you want to play the recorded source in theater level,
adjust the volume. For example, if "DialogNorm: +4
dB" appears on the display, the source being played is
recorded with 4 dB plus the THX standard level. If you
play it in the THX standard level, lower the volume by
4dB. However, not as in the theater where the playback
volume is prefixed, the unit allows you to adjust the
volume to your favorite level.
THX Cinema Processing
THX is a sound quality standard for movie theaters
developed by Lucasfilm Limited with the aim of
reproducing high-fidelity audio as close as possible
to the intentions of the filmmaker. A movie soundtrack
is mixed in special theater called dubbing stage on
the assumption that the soundtrack is played in such
theaters with similar equipment and conditions. The
movie soundtrack is also recorded on a Blu-ray disc and
DVD, but not optimized for home theater environment.
THX engineers developed the technology, now patent-
protected, to reproduce the theater sound in home
theater environment by minimizing acoustic and spatial
deviation that occurs in home theater environment. On
this unit, the THX functions are automatically added
to the Cinema mode when THX is on. (Example: THX
Cinema, THX Surround EX)
Timbre Matching
The human ears perception differs depending on the
sound coming direction. Although movie theaters have
many surround speakers to surround the room with
sound, home theaters have only two surround speakers.
The Timbre Matching function filters the signals
sent to the surround speakers and adjusts the tonal
characteristics of front speakers and surround speakers
to create smooth sound movement from front speakers
to surround speakers.
Adaptive Decorrelation
Although movie theaters have many surround speakers
to surround the room with sound, home theaters
normally have only two surround speakers. Such two
surround speakers give a headphone-like sound, not
a broad and embracing surround sound. If the listener
moves away from the middle of the surround speakers,
sound from the surround speakers mixes with that
from the near speakers and cannot be distinguished
any more. Adaptive Decorrelation slightly changes the
time axis and phase between the surround channels.
In this way, the listener can stay in a wider listening
position and enjoy theater-like sound with two surround
speakers.
ASA (Advanced Speaker Array)
ASA is a technology patented by THX to provide a
broad surround sound experience by processing the
side and back surround speaker sounds respectively.
When making home theater setting with eight speakers
(front L, center, front R, surround R, surround R back,
surround L back, surround L, and subwoofer), be sure
to select the distance between the relative surround
back speakers in the THX audio setting screen.
This procedure optimizes again the surround sound
environment. ASA is used in three modes: THX I/S
Cinema, THX I/S Music and THX I/S Games.
Checking the Input Format
You can check the audio format of the input signals. While
audio from the player is being input, press DISPLAY on the
remote controller several times to switch the information
shown on the main unit display. If "Dolby D 5.1" is displayed
in Signal format, the Dolby Digital 5.1 ch signals are being
input.

The number of channels is not displayed when the input
format is "Dolby Atmos".
