and DTS buttons can be pressed
when you are operating in Analog Mode. When a Dolby
Digital format signal is input, the surround mode
automatically switches to the DOLBY DIGITAL mode.
DTS DIGITAL SURROUND MODE
DTS lets you enjoy 5.1(or 6) discrete channels of high
quality digital audio from DTS program sources bearing
the DTS trademark, such as discs, DVD 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
throughout a true 360 . Sound field.

Note : DTS program sources should be played back in
the DTS mode.
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 on a surround
receiver/amplifier and play DVD or laser discs with
trademark, you will experience even better sound quality,
greater spatial accuracy, and improve dynamic range.
This is because Dolby Digital delivers up to 5 totally
discrete, full-frequency audio channels (from left and
right, center, and surround left and right), Plus 0.1
channel called LFE (low frequency-only effects channel).
Dolby Digital is a system developed by Dolby
laboratories that transmits 5.1 channel 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-dimensions” 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 information that allow you
to compress the dynamic range of a sound track, without
degrading the sound quality, for softer sound effects
when you listen late at night.
DOLBY PRO LOGIC II
Dolby Pro Logic
II
is the next generation of Dolby
Surround Pro Logic decoding technology.
Consumers enthusiastically demand 5.1-channel sound
in new programs of all kinds.
But vast numbers of programs already exist in stereo and
Dolby Surround, and many more will continue to arrive in
years to come. Pro Logic
II
lets consumers enjoy these
programs with a convincing 5.1-like presentation. Pro
Logic
II
can decode the thousands of existing Dolby
Surround movies and television shows already on the
shelf and with enhanced image stability.
The improvements in decoding techniques mean that the
discreteness of the sound field elements is better-
preserved in the decoding process than was possible
with the now universally standard Pro Logic technology,
developed in the mid-80s.
