■ Dolby Surround
Dolby Pro Logic II
Dolby Pro Logic II is a multi-channel playback format to convert
2-channel software into 5-channel (plus subwoofer). The matrix-
based conversion method used for Dolby Pro Logic II makes no
limitation for the cutoff frequency of the surround treble and
enables stereo surround sound.
• This receiver provides two types of Dolby Pro Logic II modes—
Pro Logic II Movie (PLII MOVIE) and Pro Logic II Music (PLII
MUSIC).
When Dolby Pro Logic II is activated, the 
 indicator lights
up on the display.
PLII MOVIE
Suitable for playing any Dolby Surround encoded
software. You can enjoy a sound field very close
to the one created with discrete 5.1-channel
sounds.
PLII MUSIC
Suitable for playing any 2-channel stereo
software. You can enjoy wide and deep sounds.
Dolby Pro Logic IIx
Dolby Pro Logic IIx is a newly introduced multi-channel playback
format to convert not only multi-channel software but 2-channel
software into 6.1 channel (or 7.1 channel) that developed from
Dolby Pro Logic II. The matrix-based conversion method used for
Dolby Pro Logic IIx makes no limitation for the cutoff frequency of
the surround treble.
• This receiver provides two types of Dolby Pro Logic IIx modes—
Pro Logic IIx Movie (PLIIx MOVIE) and Pro Logic IIx Music
(PLIIx MUSIC).
When Dolby Pro Logic IIx is activated, the 
 indicator
lights up on the display.
PLIIx MOVIE
Suitable for playing any Dolby Surround encoded
software. You can enjoy a sound field with a
natural wraparound effect.
PLIIx MUSIC
Suitable for playing any 2-channel stereo
software. You can enjoy wide and deep 6.1-
channel sounds.
• To enjoy software encoded with Dolby Digital, connect the
source component using the digital terminal on the rear of this
receiver. (See page 11.)

■ DTS**
DTS is another digital signal compression method, developed by
Digital Theater Systems, Inc., and enables multi-channel
encoding and decoding (1ch up to 6.1ch).
• When DTS signal is detected through the digital input, the DTS
indicator lights up on the display.
DTS Digital Surround
DTS Digital Surround (DTS) is another discrete 5.1 channel
digital audio format available on CD, LD, and DVD software.
Compared to Dolby Digital, the DTS Digital Surround format has a
lower audio compression rate which enables it to add breadth and
depth to the sounds reproduced. As such, DTS Digital Surround
features natural, solid, and clear sound.
DTS Extended Surround (DTS-ES)
DTS-ES is another multi-channel digital encoding format.
It greatly improves the 360-degree surround impression and
space expression by adding the third surround channel—surround
back channel.
DTS-ES includes two signal formats with different surround signal
recording methods—DTS-ES Discrete 6.1ch (ES DISCRETE)
and DTS-ES Matrix 6.1ch (ES MATRIX).
DTS-ES Discrete 6.1ch has been designed to encode (and
decode) a 6.1-channel signal discretely to avoid interference with
each channel.
DTS-ES Matrix 6.1ch has been designed to add an extra
surround channel to DTS Digital Surround 5.1-channel. By using a
matrix encoding/decoding method, an additional “surround back”
channel signal is encoded (and decoded) in both the left and right
surround channel signals.
