Creating realistic sound fields

Reproducing theater ambience

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

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

Surround/DSP modes built in this receiver can create almost the same surround sound as you can feel in a real movie theater.

Introducing the Surround/DSP modes

You can use the following Surround/DSP modes with this receiver.

■Surround modes

•Dolby Pro Logic II

•Dolby Digital

•DTS

■DSP (Digital Signal Processor) modes

•DAP (Digital Acoustic Processor) modes

•All Channel Stereo

■Surround modes

Dolby Pro Logic II*

Dolby Pro Logic II has a newly developed multi-channel 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 surround treble and enables stereo surround sound compared to conventional Dolby Pro Logic.

Dolby Pro Logic II enables you 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—suitable for 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—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 PLII indicator lights up on the display.

Dolby Digital*

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

Dolby Digital 5.1 channel 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, it is 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.

•To enjoy software encoded with Dolby Digital, connect the source component using the digital terminal on the rear of this receiver. (See pages 8 and 12.)

NOTE

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