About audio signals
Audio signals recorded in a disc contain the
sound elements (channels) shown below.
Each channel is output from a separate
speaker.
• Front (L)
• Front (R)
•Center
• Rear (L)
• Rear (R)
• Rear (Monaural): This signal can be either
the Dolby Surround Sound processed
signals or the Dolby Digital sound’s
monaural rear audio signals.
• LFE (Low Frequency Effect) signal
Note
If “DTS” is set to “OFF” in “AUDIO SETUP”
(page 63) the DTS track selection option will not
appear on the screen even if the disc contains DTS
tracks.
TV Virtual Surround
Settings
(TVS)
When you connect a stereo TV or 2 front
speakers, TVS (TV Virtual Surround) lets
you enjoy surround sound effects by using
sound imaging to create virtual rear speakers
from the sound of the front speakers (L: left,
R: right) without using actual rear speakers.
TVS was developed by Sony to produce
surround sound for home use using just a
stereo TV.
This only works when playing a multichannel
Dolby audio sound track. Furthermore, if the
player is set up to output the signal from the
DIGITAL OUT (COAXIAL) jack, the
surround effect will only be heard when
“DOLBY DIGITAL” is set to “D-PCM” in
“AUDIO SETUP” (page 63).
1 Press SUR during playback.
The following display appears.
2 Press SUR repeatedly to select
one of the TVS sounds.
