Dolby Pro Logic II*

Dolby Pro Logic II has a multi-channel playback format to decode all 2 channel sources—stereo source and Dolby Surround encoded source—into 5.1 channels.

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

Pro Logic II Music (PLII MUSIC)—suitable for the 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 multi-channel sound tracks of the software encoded with Dolby Digital (D I G I T A L ).

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

Dolby Digital 5.1 channel encoding method (so-called discrete multi-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.

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

•When Dolby Digital signal comes in, the DIGITAL indicator lights up on the display.

Note:

Dolby Digital software can roughly be grouped into two categories —multi-channel (up to 5.1 channel) and 2 channel software. To enjoy surround sounds while playing Dolby Digital 2 channel software, you can use Dolby Pro Logic II.

7DTS Digital Surround**

Used to reproduce multi-channel sound tracks of software encoded with DTS Digital Surround ().

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

DTS Digital Surround is another discrete multi-channel digital audio format available on CD, LD, and DVD software. Compared to Dolby Digital, the 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.

•When DTS signal comes in, the indicator lights up on the display.
