Checking the audio signal format
You can check the audio signal format by pressing /AUDIO repeatedly during playback. The format of the current audio signal (Dolby Digital, DTS, PCM, etc.) appears as shown below.

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 soundtrack. Furthermore, if the player is set up to output the signal from the DIGITAL OUT (OPTICAL or COAXIAL) jack, the surround effect will only be heard when �DOLBY DIGITAL� is set to �DPCM� and �MPEG� is set to �PCM� in �AUDIO SETUP� (page 61).

To cancel the setting

Select �OFF� in step 2. �TVS DYNAMIC THEATER Creates one set of LARGE virtual rear speakers and virtual subwoofer from the sound of the front speakers (L, R) without using actual rear speakers and subwoofer (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.
