Integra DTR-7.4 ユーザーズマニュアル

The DTR-7.4’s surround sound enables you to enjoy
movie theater or concert hall quality sound in your
home.
The configuration of the speakers is very important for
the surround sound effect. Refer to “About Home
Theater” on page 16.
Before selecting a listening mode, be sure to complete
the Speaker Setup (See page 32). Once the parameters
have been set, it is not necessary to set them again. See
pages 44-45 for information regarding how to select the
listening mode.

 

This mode is for playing old movies where the sound is 
recorded in monaural or for playing the left and right 
channels separately for movies that contain different lan-
guage signals. This mode also allows you to listen to the 
multiplexed soundtracks on DVDs and other media that 
have them.

 

The 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 (resulting in a 
blacked-out screen), and minimizes the sources of noise. 
The result is high-fidelity music playback true to the 
original source.

 

This mode delivers pure sound with minimal sound qual-
ity 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.

 

All input sound is output from the left and right front 
speakers.
The subwoofer is also used for playback.

 

For the best enjoyment of your home theater, it is recom-
mended that you have front left and right speakers, a cen-
ter 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 posi-
tion (sweet spot). Refer to the explanation of the listen-
ing 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.

 

As opposed to Dolby Pro Logic, which had four chan-
nels (front left/right, center, and surround) recorded into 
two channels with matrix processing and then played 
back in four channels, Dolby Pro Logic II uses a feed-
back logic circuit to have 5.1 channel surround audio 
(Dolby Surround, etc.) matrix-encoded into two chan-
nels 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 fre-
quency range, now provide complete stereo output over 
the full frequency range. The result is movie viewing 
with a realistic feel of movement. This mode can be used 
with VHS and DVD videos with the 

 

mark and certain television programs. 
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 music com-
pact discs and other stereo sources.

 

This mode is used for playing Dolby Digital sources.
Dolby Digital is compressed digital data with a maxi-
mum of 5.1 channel surround sound. This source signal 
comes from DVDs and LDs that have the 

 mark 

and therefore are recorded for 5.1 channel output.

 

Enabled when playing back sources with surround tracks 
that were encoded using the Surround EX technology.

 

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 have 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 listen-
ing to music.
The Cinema Mode is good for movies. The reproduced 
surround sound provide the same realistic feel of move-
ment 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 nor-
mal stereo output. This mode can be used with music 
CDs and other stereo sources.

 

This mode is used for playing DTS sources.
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.
