Theater-Dimensional (T-D)* mode
The ideal home theater is realized by the multichannel sound
reproduction with the complete speaker configuration and
speaker positioning described on page 12. However,
sometimes it is difficult to meet all those conditions. In reality,
you may only have front speakers, or not be able to place the
surround speakers in position.
Even if your speaker system is not complete, you can enjoy
the multichannel surround sound by using the Theater-
Dimensional mode. Theater-Dimensional mode sets the
output channels to generate the most suitable virtual
surround reproduction according to the number of the
speaker channels set in "Speaker Setup" on page 18 or 19.
The importance of the speaker setup
Calibrating each speaker's sound pressure is essential for
home theater sound reproduction. The same thing can be
said for the virtual surround sound reproduction. Especially
level matching and the time alignment of the two speakers
that reproduce virtual surround signals becomes an even
more important factor than with normal multichannel
reproduction.
For the DVD Receiver, the calibration for the multichannel
reproduction (see speaker distance setting on page 20 and
test tone adjustment on page 21) provides the most
appropriate level matching.
Notes
• For the input sources which include the surround channel signals
like multichannel DOLBY DIGITAL and DTS surround sounds, the
virtual processing is applied to those surround channel signals.
• For the 2 channel input sources, the surround channel elements
are automatically extracted with the DOLBY PRO LOGIC
processing before the virtual processing is applied.
• For the monaural or front 3 channel stereo sources, the virtual
surround effect does not work since those input sources do not
include the surround channel signals.
* Theater-Dimensional is a virtual surround technology
developed by Onkyo. This technology is approved by Dolby
Laboratories for the virtual surround processing of the
Virtual Dolby Digital and Virtual Dolby Surround products.

Listening Modes
The available listening modes varies depending on the sound
type of the input source. The table below shows the
correlation between the input source types and listening
modes.
( marked listening modes can be chosen with a particular
type of a source.)

Notes
• To reproduce MPEG2 sounds from a DVD video, you need to
change the sound conversion method to "96k Sound" or "PCM."
See "Reproducing MPEG2 Sounds from DVD Videos" on page 49.
– If you set the sound conversion method to "96k Sound," then the
listening mode is set to "Stereo."
– If you set the sound conversion method to "PCM," then you can
choose the same listening modes as "Analog/PCM" in the above
table.
• The listening mode is set to "Stereo" when the PCM sound whose
sampling frequency is higher than 48kHz is played. Such high-
resolution sounds are reproduced from sources such as DVD
video.
• If you wish to set the listening mode to "Stereo" when playing DTS
sources, select "Speaker 2ch" by repeating the procedure in
"Selecting the number of speaker channels" on page 19. If any
setting other than "Speaker 2ch" is selected, some sources may
not reproduce desirable sound.
Checking the Sound System of the
Playing Source
The DVD Receiver will automatically detect the sound
system when DOLBY DIGITAL Surround (
Surround ( ), MPEG (MPEG2 sounds from the built-in DVD
player), or PCM DIGITAL (2 channel digital stereo) is played
back. The corresponding sound system indicator lights in the
DVD Receiver's display.
