About Home Theater
Enjoying Home Theater
The DTR-7.4 has many excellent features to recreate a clear three-dimensional sound image and lively sound movement.
This enables you to easily enjoy rich sound effects just like you were in a theater or concert hall at home.
For the DTR-7.4, We recommend you to use the THX-certiŢed THX speaker system for THX Surround EX playback.
When playing a DVD, you can enjoy sound effects provided by DTS, Dolby Digital or THX, depending on recording
formats. In addition, you can enjoy IntegraOs proprietary DSP surround playback for TV or digital satellite broadcasts.
How to use speakers
When you have two speakers, they are used for front left and right speakers (2 channel playback).
When you have three speakers, they are used for front left, front right and center speakers (3 channel surround
playback).
When you have four speakers, they are used for front left, front right, surround left, and surround right speakers (4
channel surround playback).
When you have Ţve speakers, they are used for front left, front right, center, surround left and surround right
speakers (5 channel surround playback).
When you have six speakers, they are used for front left, front right, center, surround left, surround right and
surround back speakers (6 channel surround playback).
When you have seven speakers, they are used for front left, front right, center, surround left, surround right,
surround back left, and surround back right speakers (7 channel surround playback).
No matter how many speakers you use, a subwoofer can be used to produce powerful and heavy bass sound (0.1
channel playback).
Front left and right speakers
Output overall sound. They play the most important role in a home theater system, by creating basic sound
images and Ţelds.
Place the front speakers in front of the listener so that they point to the listenerOs ears in the listening position
for music and movies. Ideal speaker placement is so that they are located symmetrically.
Center speaker

ing it towards the listenerOs ears.
Also, keep the center speakerOs
height at the same level as the front
left and right speakers.
Subwoofer
Outputs only bass sounds to
enhance and complement bass
sound effects. Place the sub-
woofer either at the front corner
of the room or at a position 1/3
from either front corner of the
room.
Surround left and right speakers
Enhance the sensation of being at a live performance by giving three-dimensional
sound movement to the sound effects. Place the surround speakers at the side of
the listener or at a position diagonally from the listener. Ideally, speakers should
be placed symmetrically.
Y For optimum surround playback, set the distance between the listener and the speakers so that the time it takes the
sound to reach the listener is constant. Also, you need to set each speaker volume level individually in order to balance
the volume level between speakers (See pages 32 and 35).
