Dolby Pro Logic II*
Dolby Pro Logic II has a newly developed multi-channel
playback format to convert all 2-channel source including
Dolby Surround into 5-channel (plus subwoofer)
reproduction.
Matrix-based conversion method for Dolby Pro Logic II
makes no limitation for the cutoff frequency of the surround
treble and enables stereo surround sound unavailable with
conventional Dolby Pro Logic.
Dolby Pro Logic II can reproduce spacious sound from
original sound without adding any new sounds and tonal
colorations.
Dolby Pro Logic II has two modes—Movie mode and Music
mode.
Pro Logic II Movie (PL II MOVIE)—suitable for the
reproduction of Dolby Surround encoded software bearing
the mark (
DOLBY SURROUND
). You can enjoy a sound field very
close to the one created with discrete 5.1-channel sounds.
Pro Logic II Music (PL II MUSIC)—suitable for the
reproduction of any 2-channel stereo software. You can
enjoy wide and deep sound by using this mode.
• When Dolby Pro Logic II is activated, the
PRO LOGIC II
and SURROUND indicators light up on the display.
Dolby Pro Logic (Dolby Surround)*
Used to reproduce soundtracks of the software encoded
with Dolby Surround (
DOLBY SURROUND
).
Dolby Surround encoding format records the left front
channel, right front channel, center channel, and surround
channel signal (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 multi-channel reproduction, and allows you to
enjoy a realistic surround sound in your listening room.
• When Dolby Pro Logic is activated, the
PRO LOGIC
and SURROUND indicators light up on the display.

DTS-ES (Extended Surround)**
Used to reproduce multi-channel movie soundtracks of the
software encoded with DTS-ES (
).
DTS-ES is another new digital surround encoding format,
developed by Digital Theater Systems, Inc., that adds the
third surround channel—surround back channel. (See “Dolby
Digital EX” on page 31)
DTS ES has two types—DTS-ES Discrete 6.1-channel and
DTS-ES Matrix 6.1-channel.
DTS-ES Discrete 6.1-channel—has been designed to
encode (and decode) 6.1-channel signal discretely to avoid
interference between each channel.
DTS-ES Matrix 6.1-channel—has been designed to add an
extra surround channel to DTS Digital Surround 5.1-channel.
By using a matrix encoding/decoding method, additional
“surround back” channel signal is encoded (and decoded) in
both the left and right surround channel signals.
• When DTS-ES is activated, the
and SURROUND
indicators light up on the display.
DTS Digital Surround**
Used to reproduce multi-channel soundtracks of the software
encoded with DTS Digital Surround (
).
DTS Digital Surround is a discrete 5.1-channel digital audio
format available on CD, LD, and DVD software.
Compared to Dolby Digital, DTS Digital Surround format has
a lower audio compression ratio which enables it to add
breadth and depth to the sounds reproduced. As such, DTS
Digital Surround features natural, solid and clear sound.
• When DTS Digital Surround is activated, the
and
SURROUND indicators light up on the display.
NEO:6**
Neo:6 is a newly developed conversion method to create
6-channel (plus subwoofer) from analog/digital 2-channel
source and DTS Digital Surround source.
Neo:6 has two modes—Neo:6 Cinema and Neo:6 Music:
Neo:6 Cinema—suitable for reproduction of surround
encoded software.
Neo:6 Music—suitable for reproduction of music software.
• When NEO:6 is activated, the SURROUND indicator lights
up on the display.
• DTS Digital Surround can be converted into 6.1-channel
using NEO:6 (see page 28).
