Integra DSR-7.3 Input Sources and Available Listening Modes, Theater-Dimensional T-D* mode

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 18. 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 26.

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 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 “Setting the Distance from the Listening Position to Each Speaker” on page 27 and “Adjusting Each Speaker’s Relative Volume Balance - Test Tone” on page 28) provides the most appropriate level matching.

Notes

•For input sources which include surround channel signals like the multichannel DOLBY DIGITAL and DTS surround sounds, virtual processing is applied to those surround channel signals.

•For 2 channel input sources, the surround channel elements are automatically extracted with DOLBY PRO LOGIC processing before virtual processing is applied.

•For 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 Virtual Dolby Digital and Virtual Dolby Surround products.

The Input Sources and Available 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.

(The sources listed at the top of each column can use the listening modes marked with an ⋅.)

Note

•The listening mode is set to “STEREO” when a PCM sound with a sampling frequency higher than 48kHz is played. Such high- resolution sounds are reproduced from sources such as DVD video.

•When the Speaker setup is set to 2 channels (SP 2CH), you can’t select DOLBY DIGITAL, DTS or PLII MOVIE/PL II MUSIC. Also, when speaker setup is set to 2 channels (SP 2CH) or 3 channels (SP 3CH), you can’t select ORCHESTRA, UNPLUGGED, STUDIO-MIX, TV LOGIC or ALL CH ST.

Checking the Sound System of the Playing Source

The DVD Receiver will automatically detect the sound

system when DOLBY DIGITAL Surround ( ), DTS Surround ( ), or PCM/MP3 DIGITAL (2 channel digital stereo) is played back. The corresponding sound system indicator lights in the DVD Receiver’s display.
