Creating Realistic Sound Fields

You can use the following surround to reproduce a realistic sound field.

•Digital Multichannel Surround — Dolby Digital and DTS Digital Surround

•Dolby Surround

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 rear channel,right rear 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.

In addition,Dolby Digital enables stereo rear sounds,and sets the cutoff frequency of the rear treble at 20 kHz,compared to 7 kHz for Dolby Pro Logic.These facts enhance the sound movement and being-there feelings much more than Dolby Pro Logic.

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

DTS Digital Surround

Used to reproduce multichannel sound tracks of the software encoded with DTS Digital Surround ( ).

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 Digital Surround signals,the DTS indicator lights up on the display.

Effect

To increase Effect level

Used to reproduce sound tracks of the VCR tapes encoded with Dolby Surround ( ). This is only used for the sound sources coming through the AUX IN jacks.

Dolby Pro Logic and Dolby 3 Stereo

Dolby Surround encoding format records the left front channel, right front channel,center channel,and rear channel signals (total 4 channels)into 2 channels.

The Dolby Pro Logic decoder built in this system decodes these 2 channel signals into original 4 channel signals — matrix-based multichannel reproduction,and allows you to enjoy a realistic stereo sound in your listening room.

When one of Dolby Surround is selected,the PRO LOGIC indicator lights up on the display.
