About DVD encoding and playback of
Surround EX (6.1 Channel) movies
The Surround EX System used in movie
theaters employs a matrix system to produce
6.1 channels from a 5.1 channel film
soundtrack. The matrix system reproduces the
soundtrack as intended by the filmmaker. All
DVD software encoded with Dolby Digital,
DTS-ES matrix 6.1, and DTS-ES Discrete 6.1
includes the 5.1 channel soundtrack designed
for use in movie theaters. Therefore it is
possible to change the soundtrack to the one
designed for use in movie theaters.
To enjoy 6.1 channel surround sound
(“VIRTUAL MATRIX 6.1” playback
function)
• If you do not connect a surround back speaker.
You can still enjoy 6.1 channel surround sound
even if you do not connect a surround back speaker.
Press SURR BACK DECODING when you select
“CINEMA STUDIO EX A-C” to use the
“VIRTUAL MATRIX 6.1” playback function. The
sound charateristics of CINEMA STUDIO and the
3D sound imaging create a virtual surround back
speaker, and you can experience the surround effect
as if you are in a real theater.
Select “AUTO” or “MATRIX” using the SURR
BACK DECODING button.
• If you connect a surround back speaker.
When “NORMAL SURROUND” is selected, press
SURR BACK DECODING to select “MATRIX” or
“AUTO”.
Selecting the surround
back decoding mode
(SURR BACK DECODING)
You can select the surround back decoding
mode to reproduce the surround back signal
and enjoy 6.1 channel surround sound.
Press SURR BACK DECODING to select the
surround back decoding mode. “SB
DECODING XXXXXX” appears in the
display and SB DEC indicator lights up.
• When set to “AUTO”, the receiver performs
6.1 channel matrix decoding only if the 6.1
channel signals decode flag is ON.
• When set to “MATRIX”, the receiver performs
6.1 channel matrix decoding only if the
surround signals are 2 channel, regardless of the
6.1 channel decode flag.
• When set to “OFF”, the receiver does not
perform 6.1 channel matrix decoding.
• When the 6.1 channel matrix decoding is
performed and the surround back speaker is set
to “NO”, you can enjoy the surround back
signals with virtual 3D technology, even
without an actual surround back speaker (the
box around SB does not light up). If the
surround back speaker is set to “YES”, the
surround back signals are output through the
actual speaker (SB and the box lights up).
This function works only for the multi channel
format [3/2].
This function is effective for the following
sound fields.
• AUTO DECODING
• NORMAL SURROUND
• CINEMA STUDIO EX A–C
• MONO MOVIE
• STEREO MOVIE
Tip
You can also select the surround back decoding mode
using the SB DECODING parameter in the
CUSTOMIZE menu (page 44).
