Creating Realistic Sound Fields

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

•Digital Multichannel Surround —Dolby Digital and DTS Digital Surround

•Dolby Pro Logic II

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 (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).

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 result in better sound quality 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 for 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.

Dolby Pro Logic II		SETUP
• Dolby Pro-Logic II is a new multi-channel playback format developed by Dolby Laboratories using feedback logic
steering technology and offering improvements over conventional Dolby Pro Logic circuits.
• Dolby Pro Logic II can be used to decode not only sources recorded in Dolby Surround (	) but also

regular stereo sources into five channels (front left, front right, center, surround left and surround right) to achieve surround sound.

• Whereas with conventional Dolby Pro Logic the surround channel playback frequency band was limited, Dolby Pro Logic II offers a wider band range.

Test Tone FUNCTION

Press the TEST TONE button on the remote control.

•This function allows you can easily adjust the sound balance of the speakers from the listener's position.

•The test signal will be sent to the Left Front ➞ Center ➞ Right Front ➞ Right Rear ➞ Left Rear ➞ LFE in that order.

To End the Speaker Setup

•Press the TEST TONE button again.

In addition, the surround channels were monaural (the surround left and right channels were the same) with previous Dolby Pro Logic, but with Dolby Pro Logic II they are stereo.

*Sources recorded in Dolby Surround

These are sources in which three or more channels of surround have been recorded as two channels of signals using Dolby Surround encoding technology.

Dolby Surround is used for the sound tracks of movies recorded on DVDs, LDs and video cassettes to be played on stereo VCRs, as well as for the stereo broadcast signals of FM radio, TV, satellite broadcasts and cable TV. Decoding these signals with Dolby Pro Logic makes it possible to achieve multi-channel surround playback.

The signals can also be played on ordinary stereo equipment, in which case they provide normal stereo sound.
