SURROUND MODE
The surround modes create a “live” atmosphere such as that
experienced in movie theaters, discos, stadiums and concert halls.
Select the appropriate surround mode according to the program
source. (Note: Surround speakers are needed for DTS/DOLBY
DIGITAL Dolby Pro Logic II surround modes to function).
It is recommended to use a Center speaker when operating this
unit in DTS/DOLBY DIGITAL/Dolby Pro Logic II surround modes.
The
DOLBY DIGITAL button can be pressed when you are using either
an Optical or Coaxial cable as the input connection because these
cables transmit the required encoded digital data.

DTS DIGITAL SURROUND MODE
This unit is provided with the following Surround modes allowing
you to enjoy 5.1 (or 6) discrete channels of high quality digital
audio from DTS program sources bearing the DTS trademark such
as discs, DVDs and compact discs, etc. DTS Digital Surround
delivers up to 6 channels of transparent audio (which means
identical to the original masters) and results in exceptional clarity
within a genuine 360 degree sound field. The term DTS is a
trademark of DTS Technology, LLC. Manufactured under license

DOLBY DIGITAL MODE
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 or an LD player equipped with a DOLBY
DIGITAL output to the DIGITAL (Dolby Digital)/DTS/PCM DIGITAL
IN jack (Optical or Coaxial digital IN) on your AV Receiver and play
DVD or laser discs with the Dolby Digital trademark, you will
experience exceptional sound quality, great spatial accuracy, and
improved dynamic range. This is because Dolby Digital delivers 5
totally discrete, full frequency audio channels (Front Left Right,
Center, Surround Left and Right), plus a "0.1" channel called LFE
(Low frequency-only effects channel).
Dolby Digital is a system developed by Dolby laboratories that
transmits 5.1 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-dimensions” feel is achieved
which gives the sound a sense of distance, movement and relative
position, creating a 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 watching movies late
at night.
