Listening Modes
The DTR-6.4/5.4’s surround sound enables you to enjoy the
presence of a movie theater or concert hall in your room.
The configuration of the speakers is very important for the surround
sound. Refer to “About Home Theater” on page 14.
Before using a listening mode, make sure the Speaker Config has
been set (see page 33). Once the parameters have been set, it is not
necessary to set them again. For getting accurate surround effect,
you are recommended to perform the settings on the Speaker
Distance and Level Calibration (see pages 52 to 55). See pages 46
and 47 for information regarding how to select the listening mode.
Mono
This mode is for playing old movies where the sound is recorded in
monaural or for playing the left and right channels of movies
separately that contain different language signals. This mode also
allows you to listen to the multiplexed soundtracks on DVDs, and
other media that have them.
Direct
This mode delivers pure sound with minimum sound quality
adjustment and filtration. The sound recorded for the right and left
front channels is output to the right and left front speakers only and
not output to the subwoofer.
Pure Audio (DTR-6.4 only)
Same as the direct mode except that the pure audio mode also turns
off the display window, turns off the power supply to the video
circuitry, and minimizes the sources of noise. The result is high-
fidelity music playback true to the original source.
Stereo
All input sound is output from the left and right front speakers.
The subwoofer is also used for playback.
T-D (Theater-Dimensional)
For the best enjoyment of your home theater, it is recommended that
you have front left and right speakers, a center speaker, and surround
left and right speakers. However, if you only have front left and right
speakers, you can enjoy multichannel audio by using this mode.
This mode controls the characteristics of the sound that reaches
each ear to reproduce a multi-speaker setup. To receive the full
effect, there is an optimum listening position (sweet spot). Refer to
the explanation of the listening angle. In addition, if the reflective
sound components are large, it may be difficult to achieve the
desired result, so be sure to set up your system and listening
position to minimize reflective sound.
Dolby Pro Logic II
Opposed to Dolby Pro Logic, which had four channels (front, left,
center, and surround) recorded into two channels with matrix
processing and then played back in four channels, Dolby Pro Logic
II uses a feedback logic circuit to have 5.1-channel surround audio
(Dolby Surround, etc.) matrix-encoded into two channels and then
played back in its original 5.1-channel form.
Dolby Pro Logic II provides a Movie mode designed for playing
movies and a Music mode designed for listening to music. In the
Movie mode, the surround channels, which used to provide
monaural output over only a narrow frequency range, now provide
complete stereo output over the full frequency range. The result is
movie viewing with a realistic feel of movement. The Music mode
uses the surround channels to provide a natural soundfield that
cannot be provided with normal stereo output.
This mode can be used with VHS and DVD videos with the
mark and certain television programs. The
Music mode can be used with music compact discs and other stereo
sources.
Dolby D (Dolby Digital)
This mode is used for playing Dolby Digital sources.
Dolby Digital is compressed digital data with a maximum of 5.1-
channel surround sound. This source signal comes from DVDs and
LDs that have the mark and therefore recorded for 5.1-
channel output.
Listening Modes
• Dolby Digital EX
Enabled when playing back sources with surround tracks that
were encoded using the Surround EX technology.
• Dialog norm
Dialogue Normalization (Dialog Norm) is a feature of Dolby
Digital. When playing back software that has been encoded in
Dolby Digital, sometimes you may see a brief message in the
front panel display that reads Dialog Norm xdB (“x” being a
numeric value). Dialogue Normalization serves to let you know
if the source material has been recorded at a higher or lower
level than usual. This data is automatically used by the Dolby
Digital decoder to adjust the output volume of the source
material without affecting the volume of your amplifier.
Therefore, even if source material volume changes, you will
not have to adjust the volume on your amplifier.
DTS Neo:6
This mode is for 6.1-channel playback of sources such as PCM or
analog sources that have only two channels. The outputs of all six
channels are a wide frequency range with a great separation
between the different channels.
This mode can be set to the Cinema mode designed for playing
movies and the Music mode designed for listening to music.
The Cinema mode is good for movies. The reproduced surround
sound provide the same realistic feel of movement as 6.1-channel
sources. This mode can be used with VHS and television programs
with stereo sound.
The Music mode uses the surround channels to provide a natural
sound space that cannot be provided with normal stereo output. This
mode can be used with music CDs and other stereo sources.
DTS
This mode is used for playing DTS source.
DTS (Digital Theater System) is compressed digital data with a
maximum 5.1-channel surround output (6.1-channel with DTS-ES
Discrete sources) that allows for an extremely high-quality sound. This
source signal requires a DVD player that supports DTS output and
comes from DVDs, compact discs, and LDs that have the mark.
DTS-ES Discrete 6.1
With the addition of the surround back channel, this new format has all 6.1
channels recorded independently for a completely discrete digital format.
Since all channels are recorded independently, high-fidelity surround
playback with the increased feeling of a separated sound space is achieved.
DTS-ES Matrix 6.1
This format has the surround back channel matrix encoded and
inserted into the left and right surround channels so that at playback
the output for the left, right, and back surround channels are
decoded using a high-precision matrix decoder.
DTS 96/24
Automatically changes to this mode when playing back sources with
surround tracks that were encoded using the DTS 96/24 technology.
THX (DTR-6.4 only)
THX is an exclusive set of standards and technologies established by
the world-renowned film production company, Lucasfilm Ltd. THX
grew from George Lucas’ personal desire to make your experience
of the film soundtrack, in both movie theaters and in your home
theater, as faithful as possible to what the director intended.
Movie soundtracks are mixed in special movie theaters called
dubbing stages and are designed to be played back in movie theaters
with similar equipment and conditions. This same soundtrack is then
transferred directly onto LD, VHS tape, DVD, etc., and is not
changed for playback in a small home theater environment.
THX engineers developed patented technologies to accurately
translate the sound from the movie theater environment into the home,
correcting the tonal and spatial errors that occur. On this product,
when the THX indicator is on, THX features are automatically added
in Cinema modes (e.g. THX Cinema, THX Surround EX).
• THX Cinema
This is the conventional 5.1-channel THX mode. This mode
should be used only when playing back sources that were mixed
for playback in large movie theater environments.
