■Dolby Digital and DTS Digital Surround

To enjoy surround effectively, all the speakers need to be connected and activated.

Dolby Digital*

Used to reproduce multichannel sound tracks of the software

encoded with Dolby Digital ().

Dolby Digital encoding method (so-called discrete 5.1 channel digital audio format) records and digitally compresses the left front channel, right front channel, center channel, left surround channel, right surround channel, and LFE channel signals (total 6 channels, but LFE channel is counted as 0.1 channel. Therefore, called 5.1 channel).

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 effects.

When the system detects Dolby Digital signals, the indicator lights up on the display.

DTS Digital Surround**

Used to reproduce multichannel sound tracks of the software

encoded with DTS ( or ).

DTS Digital Surround is another discrete 5.1 channel digital audio format available on CD, LD, and DVD software.

Compared to Dolby Digital, audio compression rate 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.

When the system detects DTS signals, the indicator lights up on the display.

■Dolby Pro Logic II modes

Dolby Pro Logic II*

Dolby Pro Logic II is the multichannel playback format to decode any 2 channel (stereo) sources—either digital or analog—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 four modes—Music mode, Movie mode, Matrix mode, and Pro Logic mode:

Pro Logic II Music (PLII MUSIC)—suitable for reproduction of any 2 channel stereo music sources. You can enjoy wide and deep sound by using this mode.

Pro Logic II Movie (PLII MOVIE)—suitable for reproduction of Dolby Surround encoded sources bearing the mark DOLBY SURROUND . You can enjoy sound field very close to the one created with discrete 5.1 channel sounds.

Pro Logic II Matrix (PLII MATRIX)—suitable for reproduction

of monaural sources.

Pro Logic (PRO LOGIC)—suitable for reproduction of sources encoded with Dolby Surround.

•When one of Dolby Pro Logic II modes is activated, the
