SURROUND MODE
The SR6400 is equipped with many surround
modes. These are provided to reproduce a variety
of surround sound effects, according to the content
of the source to be played.
The available surround modes may be restricted
depending on the input signal and speaker setup.
AUTO
When this mode is selected, the receiver determines
whether the digital input signal is Dolby Digital,
Dolby Digital Surround EX, DTS, DTS-ES, DTS 96/
24 or PCM-audio.
S u r r o u n d E X & D T S - E S w i l l o p e r a t e f o r
multichannel source that has a Dolby Digital
Surround EX or DTS-ES auto trigger flag in the
digital signal.
When a Dolby Digital or DTS signal is input, the
number of channels for which the corresponding
signal is encoded will be played.
Inputting a Dolby Digital two channel signal with
Dolby surround status automatically subjects that
signal to Pro Logic
II
movie processing before play.
PCM 96 kHz source material can be played in this
mode.
Notes:
• When you use this mode with certain DVD and
CD players, performing operations such as “Skip”
or “Stop” may momentarily interrupt the output.
• When the signal is not decoded, the mode is changed
to AUTO mode automatically. Refer to page 22 to
confirm the available decoding mode.

MODE
(Dolby Digital, Pro Logic
II
MOVIE, Pro Logic
II
MUSIC, Pro Logic)
This mode is used with source materials encoded
in Dolby Digital and Dolby Surround.
DOLBY DIGITAL
This mode is enabled when playing source materials
encoded in Dolby Digital.
Playing multichannel encoded 5.1-channel Dolby
Digital sources provides five main audio channels
(left, center, right, surround left and surround right)
and Low Frequency Effect channel.
Dolby Digital EX decoding is not available in this
mode.
Dolby Pro Logic II brings the excitement of surround
sound to any stereo mix, while making existing
Dolby Surround mixes sound more like discrete 5.1
channels Surround sound.
Dolby Pro Logic II has 3 modes. Please see below.
Pro Logic
II
MOVIE
This mode provides 5.1 channel surround sound
from Dolby Surround encoded stereo movie sound
tracks.
Pro Logic
II
MUSIC
This mode provides 5.1 channel surround sound
from conventional stereo sources, analog or digital,
such as CD, Tape, FM, TV, Stereo VCR, etc.
Pro Logic
This mode emulated original Dolby Pro Logic
decoding (3/1 surround) suit for Dolby Surround
encoded stereo movie soundtracks.
Notes:
• Pro Logic II mode is available for a 2ch input signal
which is encoded in Dolby Digital or PCM format.
• PCM-audio signals can be subjected to Pro Logic
processing when the sampling frequency is 32
kHz, 44.1 kHz or 48 kHz.
EX/ES
This mode provides 6.1 channel surround for
DOLBY DIGITAL EX, DTS-ES encoded source
material such as DVD.
This mode cannot be used when an analog input
has been selected.
Dolby Digital EX
In a movie theater, film soundtracks that have been
encoded with Dolby Digital surround EX technology
are able to reproduce an extra channel which has
been added during the mixing of the program.
This channel, called Surround Back, places sounds
behind the listener in addition to the currently
available front left, front center, front right, surround
right, surround left and subwoofer channels.
This additional channel provides the opportunity
for more detailed imaging behind the listener and
brings more depth, spacious ambience and sound
localization than ever before.
Dolby Digital EX is not available in the system
without surround back speaker(s).
DTS-ES (Discrete 6.1, Matrix 6.1)
DTS-ES adds the surround center channel audio to
the DTS 5.1-channel format to improve the acoustic
positioning and makes acoustic image movement
more natural with the 6.1-channel reproduction.
This receiver incorporates a DTS-ES decoder, which
can handle DTS-ES Discrete-encoded and DTS-ES
Matrix-encoded program sources from DVD, etc..
DTS-ES Discrete 6.1 features digital discrete
recording of all channels including the surround back
channel(s) and higher quality of audio reproduction.
DTS-ES is not available in the system without a
surround back speaker.
dts MODE
(dts, Neo:6 Cinema, Neo:6 Music)
This mode is for DTS encoded source materials
such as LASER DISC, CD, and DVD. Neo:6 is for
some 2 channel sources.
dts
: This mode is enabled when playing source
materials encoded in dts multichannel.
Playing multichannel encoded 5.1-channel dts
sources provides five main audio channels (left,
center, right, surround left and surround right) and
Low Frequency Effect channel.
dts-ES decoding is not available in this mode.
The DTS mode cannot be used when an analog
input has been selected.
Neo:6 Cinema, Neo:6 Music
This mode decodes 2-channel signals into 6-
channel signals using high-accuracy digital matrix
technology.
The DTS NEO:6 decoder has near-discrete
properties in the frequency characteristics of the
channels as well as in channel separation.
According to the signals to be played back, DTS
NEO:6 uses either the NEO:6 CINEMA mode
optimized for movie playback or the NEO:6 MUSIC
mode optimized for music playback.
Note:
• Neo:6 mode is available to 2ch input signals which
are encoded in Dolby Digital or PCM format.
• PCM-audio signals can be subjected to Pro Logic
processing when the sampling frequency is 32
