Sony DVP-NC615 Operating Instructions Manual page 49

• "TVS NIGHT" only works with Dolby Digital
and MPEG audio discs. However, not all discs
will respond to the "TVS NIGHT" function in the
same way.
• If you use the DIGITAL OUT (COAXIAL) jack
and set "DOLBY DIGITAL" to "DOLBY
DIGITAL" or "DTS" to "ON" in "AUDIO
SETUP," sound will come from your speakers but
it will not have the TVS effect.
