Notes:
• CS II mode is available for 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
kHz, 44.1 kHz or 48 kHz.
VIRTUAL
This mode creates a virtualized surround sound
experience from a two-speaker (front L and R)
playback system playing any multichannel audio
source (such as found on DVDs and digital
broadcasts), including Dolby Digital, Dolby Pro
Logic or DTS.
STEREO
This mode bypasses all surround processing.
In stereo program sources, the left and right
channels play normally when PCM-audio or
analog stereo is input.
With Dolby Digital and DTS sources, the 5.1
multichannels are converted to two channel
stereo. 96 kHz PCM source material can be played
back in stereo mode.
PURE DIRECT
In the pure direct mode, the tone control circuit and
bass management configuration are bypassed for
full range frequency response and the purist audio
reproduction.
96 kHz PCM source material can be played back in
this mode.
Notes:
• Internal speaker size is setup to front L/R =
LARGE, Center = LARGE, Surround L/R =
LARGE and Subwoofer = YES automatically.
Tone controls and additional processing are also
defeated.
• When you use this mode with certain DVD and
CD players, performing operations such as “Skip”
or “Stop” may momentarily interrupt the output.
CAUTION
NOTE for DTS signal
* Connected DVD-player, laser-disc player or CD-
player needs to support DTS-digital output. You
may not be able to play some DTS source
signals from certain CD players and LD players
even if you connect the player to the SR7500
digitally. This is because the digital signal has
been processed (such as the output level,
sampling frequency, or frequency response)
and the SR7500 cannot recognize the signal as
DTS data.
* Depending on the player used, DTS play may
produce a short noise. This is not a malfunction.
* While signals from DTS-laser disc or CD are
playing in another Surround mode, you cannot
switch to digital input or from digital input to
analog input by INPUT SETUP in SETUP MAIN
MENU or the A/D button.
* You can not listen to DTS-encorded course in
Multi room.
* The outputs for the VCR 1 OUT, DSS/VCR 2
OUT, TAPE OUT, and CD-R OUT output analog
audio signals. Do not record from CDs or LDs
that support DTS using these outputs. If you do,
the DTS-encoded signal will be recorded as
noise.
NOTE for Dolby Digital Surround EX signal
* When playing Dolby Digital Surround EX-
encoded software in 6.1 channels, it is required
to set the EX/ES mode.
* Note that some of Dolby Digital Surround EX-
encoded software does not contain the
identification signal. In this case, set the EX/ES
mode manually.
NOTE for 96kHz PCM audio
* AUTO, PURE DIRECT, and STEREO modes
can be used when playing PCM signals with a
sampling frequency of 96 kHz (such as from
DVD-Video discs that contain 24 bit, 96 kHz
audio). If such signals are input during playback
in one of the other surround modes, output from
SR7500 will be muted.
* Certain DVD player models inhibit digital output.
For details, refer to the player’s operation
manual.
* Some DVD formatted discs feature copy
protection. When using such disc, 96 kHz PCM
signal is not output from the DVD player. For
details, refer to the player’s operation manual.
NOTE for HDCD signal (SR8500 only)
* HDCD is effective only at the time of digital
input.
* AUTO, PURE DIRECT, and STEREO modes
can be used when playing HDCD signals (such
as from CD discs that contain HDCD).
* You may not be able to play some HDCD source
signals from certain CD players if you connect
the player to the SR8500 digitally. This is
because the digital signal has been processed
(such as the output level, sampling frequency, or
frequency response) and the SR8500 cannot
recognize the signal as HDCD data.
Notes:
• Pro Logic IIx mode will decode as Pro Logic II
mode when the SURROUND BACK SPEAKER
is set NONE in SPEAKER SETUP menu. (See
SPEAKER SETUP, page 19)
• Pro Logic IIx 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.
Notes:
•
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
kHz, 44.1 kHz or 48 kHz.
MULTI CH. ST
This mode is used to create a wider, deeper and more
natural soundstage from two channel source material.
This is done by feeding the left channel signal to
both left front and left surround speaker and the
right channel signal to both right front and right
surround speaker. Additionally, the center channel
reproduces a mix of the right and left channel.
CIRCLE SURROUND
II
(CS
II
-CINEMA, CS
II
-MUSIC, CS
II
-MONO)
Circle Surround is designed to enable multichannel
surround sound playback of non-encoded and
multichannel encoded material.
Backward compatibility provides listeners with up
to 6.1 channels of surround performance from
entire collection of music and film, including
broadcast, videotape and stereo recorded music.
Depending on source material, you can select
CSII-Cinema mode, CSII-Music mode or CSII-
Mono mode.
