Creating Realistic Sound Fields

You can use the following Surround modes to reproduce a realistic sound field:

■Dolby Surround

•Dolby Pro Logic II

•Dolby Digital

■DTS Digital Surround

■DAP modes

■All Channel Stereo

■Dolby Surround

Dolby Pro Logic II*

Dolby Pro Logic II has a newly developed multichannel playback format to decode all 2 channel sources—stereo source and Dolby Surround encoded source—into 5.1 channel.

Matrix-based encoding/decoding method for Dolby Pro Logic II makes no limitation for the cutoff frequency of the rear treble and enables stereo rear sound compared to conventional Dolby Pro Logic.

Dolby Pro Logic II enables to reproduce spacious sound from original sound without adding any new sounds and tonal colorations. Dolby Pro Logic II has two modes—Movie mode and Music mode:

Pro Logic II Movie (PL II MOVIE)—suitable for reproduction of

Dolby Surround encoded sources bearing the mark DOLBY SURROUND . You can enjoy soundfield very close to the one created with discrete 5.1 channel sounds.

Pro Logic II Music (PL II MUSIC)—suitable for reproduction of any 2 channel stereo music sources. You can enjoy wide and deep sound by using this mode. For this mode, Panorama control can be selected, which gives “wraparound” sound effect with side-wall image.

•When Dolby Pro Logic II is activated, the PRO LOGIC II indicator lights up on the display.

Dolby Digital*

Used to reproduce multichannel sound tracks of the software encoded with Dolby Digital ( D I G I T A L ).

•To enjoy the software encoded with Dolby Digital, connect the source component using the digital terminal on the rear of this receiver. (See page 9.)

Dolby Digital 5.1 ch encoding method (so-called discrete multichannel digital audio format) records and digitally compresses the left front channel, right front channel, center channel, left rear channel, right rear channel, and LFE channel signals.

Since each channel is completely independent from the other channel signals to avoid interference, you can obtain much better sound quality with much stereo and surround effect.

Note:

Dolby Digital software can be roughly grouped into two categories

—multichannel (up to “5.1” ch) and 2 channel software. To enjoy surround sounds while playing Dolby Digital 2 ch software, you can use Dolby Pro Logic II.

■DTS Digital Surround**

Used to reproduce multichannel sound tracks of the software encoded with DTS Digital Surround ().

•To enjoy the software encoded with DTS Digital Surround, connect the source component using the digital terminal on the rear of this receiver. (See page 9.)

DTS Digital Surround is another discrete multichannel digital audio format available on CD, LD, and DVD software. Compared to Dolby Digital, audio compression ratio is relatively low. This fact allows DTS Digital Surround format to add breadth and depth to the reproduced sounds. As a result, DTS Digital Surround features natural, solid and clear sound.
