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 source 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 SR4500
digitally. This is because the digital signal has
been processed (such as the output level,
sampling frequency, or frequency response)
and the SR4500 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.
* 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
SR4500 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.
