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.

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.
