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

• If “DTS” is set to “OFF” in “AUDIO SETUP,” 

the DTS track selection option will not appear on 
the screen even if the disc contains DTS tracks 
(page 58).

• While playing a Super VCD on which the audio 

track 2 is not recorded, no sound will come out 
when you select “2:STEREO,” “2:1/L,” or
“2:2/R.”

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.
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” 
(page 58).

The following display appears.

Select “OFF” in Step 2.

◆TVS DYNAMIC
Creates virtual rear speakers from the sound 
of the front speakers (L, R) without using 
actual rear speakers (shown below).
This mode is effective when the distance 
between the front L and R speakers is short, 
such as with built-in speakers on a stereo TV.

◆TVS WIDE
Creates virtual rear speakers from the sound 
of the front speakers (L, R) without using 
actual rear speakers. The virtual speakers are 
reproduced as shown in the illustration 
below.
This mode is effective when the distance 
between the front L and R speakers is short, 
such as with built-in speakers on a stereo TV.

◆TVS NIGHT 
Large sounds, such as explosions, are 
suppressed, but the quieter sounds are 
unaffected. This feature is useful when you 
want to hear the dialog and enjoy the 
surround sound effects of “TVS WIDE” at 
low volume.

◆TVS STANDARD
Creates virtual rear speakers from the sound 
of the front speakers (L, R) without using 
actual rear speakers. The virtual speakers are 
reproduced as shown in the illustration 
below. Use this setting when you want to use 
TVS with 2 separate speakers.
