Reproducing Theater Ambience

Introducing the Surround Modes

In a movie theater, many speakers are located on the walls to reproduce impressive multi-surround sounds, reaching you from all directions.

With these many speakers, sound localization and sound movement can be expressed.

Surround modes built in this receiver can create almost the same surround sounds as you can feel in a real movie theater—with only a limited number of the speakers.

Dolby Digital*1

Dolby Digital is a digital signal compression method, developed by Dolby Laboratories, and enables multi-channel encoding and decoding (1ch up to 5.1ch).

•When Dolby Digital signal is detected through the digital input,

the

indicator lights up on the display.

Dolby Digital 5.1CH

Dolby Digital 5.1CH (DOLBY DIGITAL) encoding method 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 the LFE channel is counted as 0.1 channel. Therefore, called 5.1 channel). Dolby Digital enables stereo surround sounds, and sets the cutoff frequency of the surround treble at 20 kHz, compared to 7 kHz for Dolby Pro Logic. As such, the sound movement and “being-there” feeling are enhanced much more than Dolby Pro Logic.

Another digital surround encoding format introduced by Dolby Laboratories is Dolby Digital EX, which adds the third surround channels, called “surround back.”

Compared to the conventional Dolby Digital 5.1CH, these newly added surround back channels can reproduce more detailed movements behind you while viewing the video software. In addition, surround sound localization will become more stable.

•You can use Virtual Surround Back (see page 22) when playing back Dolby Digital EX software. This function creates the great surround effect from the behind as if you have connected the surround back speakers.

Dolby Pro Logic II

Dolby Pro Logic II is a multi-channel playback format to convert 2-channel software into 5-channel (plus subwoofer). The matrix- based conversion method used for Dolby Pro Logic II makes no limitation for the cutoff frequency of the surround treble and enables stereo surround sound.

•This receiver provides two types of Dolby Pro Logic II modes— Pro Logic II Movie (PLII MOVIE) and Pro Logic II Music

(PLII MUSIC).

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

PLII MOVIE: Suitable for playing any Dolby Surround encoded software. You can enjoy a sound field very close to the one created with discrete 5.1- channel sounds.

PLII MUSIC: Suitable for playing any 2-channel stereo software. You can enjoy wide and deep sounds.
