When playing a DVD recorded in multiple 
audio formats (PCM, Dolby Digital or DTS), 
you can change the audio format. If the DVD 
is recorded with multilingual tracks, you can 
also change the language.
With CDs, DATA CDs, or VIDEO CDs, you 
can select the sound from the right or left 
channel and listen to the sound of the selected 
channel through both the right and left 
speakers. For example, when playing a disc 
containing a song with the vocals on the right 
channel and the instruments on the left 
channel, you can hear the instruments from 
both speakers by selecting the left channel.

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 or 
OPTICAL) jack, the surround effect will only 
heard when “DOLBY DIGITAL” is set to 
“D-PCM” (page 68).

The following display appears.

Refer to the following explanations given 
for each item.
• TVS DYNAMIC
• TVS WIDE
• TVS NIGHT
• TVS STANDARD

To cancel the setting
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.
