Creating realistic sound fields

This system activates a variety of Surround modes and DSP (Digital Signal Processor) modes. To use Surround or DSP modes properly, speakers required for creating each Surround and DSP mode should be activated.

7Reproducing theater ambience

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 system can create almost the same surround sounds as you can feel in a real movie theater.

7Introducing the Surround modes

Dolby Surround
Dolby Digital EX*

Best used to reproduce multi-channel movie soundtracks of

the software encoded with Dolby Digital EX ( Surround modes ). Dolby Digital EX is a newly introduced surround encoding format as an extension of multi-channel Dolby Digital, designed to add an extra surround channel to Dolby Digital 5.1-channel (see below). By using a matrix encoding/ decoding method, additional “surround back” channel signal is encoded (and decoded) in both the left and right surround channel signals.

Compared to the conventional Dolby Digital 5.1-channel, this newly added surround back channel can reproduce more detailed movements behind you while viewing the video software. In addition, surround sound localization will become more stable, so that you can enjoy a realistic surround field in your listening room.

When Dolby Digital EX is activated, the 7Reproducing theater ambience DIGITAL EX and SURROUND indicators light up on the display.

Dolby Digital*

Used to reproduce multi-channel soundtracks of the software

encoded with Dolby Digital ( 7Introducing the Surround modes ).

Dolby Digital 5.1-channel 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 a much better sound quality with better stereo and surround effects.

When Dolby Digital is activated, the Dolby Surround DIGITAL and SURROUND indicators light up on the display.

*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.

NOTE: MPEG Multichannel

MPEG Multichannel signals are converted into Linear PCM signals, then reproduced.
