AVAILABLE SURROUND MODES
When you use the surround function, the sound creates a “live” atmosphere such as that experienced in
movie theaters, discos, stadiums and concert halls. This unit is provided with the following surround
modes, which can be selected using the SURROUND MODE switches.
Select the appropriate surround mode according to the program source.
• Note that surround speakers are needed for the Dolby Pro Logic Surround mode to function, and a
center speaker is needed for the 3 Stereo mode to function.
DTS (DIGITAL THEATER SYSTEM)
Allows you to enjoy 5.1 (or 6) discrete channels of high quality digital audio from DTS program sources
bearing the
, or “HIGH DEFINITION SURROUND” trademark such as discs, DVD and compact
discs, etc. DTS DigitalSurround delivers up to 6 channels of transparent audio (which means identical to
the original masters) and results in exceptional clarity throughout a true 360° soundfield. The term DTS is
a trademark of DTS Technology, LLC. Manufactured under license from DTS Technology, LLC.
NOTE
The DTS program sources should be played back in the DTS mode. If not, it will sound like continuous
noise.
DOLBY DIGITAL SURROUND
The Dolby Digital surround format lets you enjoy up to 5.1 channels of digital surround sound from a
Dolby Digital program source. If you connect a DVD player equipped with an DOLBY DIGITAL output to
the
DIGITAL (Dolby Digital) / DTS / PCM DIGITAL IN jack on a surround receiver/amplifier or surround
processor and play DVD with the mark, you can enjoy even better sound quality, greater spatial
accuracy, and improved dynamic range. This is because Dolby Digital delivers up to 5 totally discrete, full
frequency audio channels (front left and right, center, and surround left and right), plus 0.1 channel called
LFE (bass-only effects channel).
Dolby Digital is a system developed by Dolby Laboratories that transmits 5.1 channels of digital signals.
The surround system developed for movie theaters using this system is called “Dolby SR-D (Surround
Digital)”. Because each channel is completely independent, a realistic sound field with a “three-
dimensional” feel is achieved which gives the sound a sense of distance, movement and relative position,
creating a surprisingly real and powerful sense of presence.
Some Dolby Digital programs carry information that allow you to compress the dynamic range of sound
track, without degrading the sound quality, for softer sound effects when you listen late at night.
LFE: LOW FREQUENCY EXTENSION
This channel delivers separate non-directional bass signals to the subwoofer for more dynamic deep bass
sound effects.
DOLBY PRO LOGIC II
Use this mode when playing movie or music video software which carries the DPL II mark. This mode
provides the effect of being in a movie theater or live concert house-an effect with an intensity which can
only be obtained through DOLBY PRO LOGIC II SURROUND. The main feature of DOLBY PRO LOGIC II is
that the frequency response of the surround channels is significantly improved from 7 kHz to full 20 to
20 kHz bandwidth with channel separation of 26 to 40 dB.
As a result, the effect of the front/back/ left/right movement of the sound image, as well as the sense of
fixed position in the sound image, is much clearer and more dynamic than before.
In addition, movie dialogue and other sounds which should naturally be heard from the center are output
through an independent center channel, providing a high degree of focus for dialogue.
