DESC: The Panasonic SCPT670 Home Theater System will enhance your favorite movies and TV shows with rich, immersive sound. One of the major obstacles in setting up a Home-theater Surround Sound system is the wiring of those rear speakers. .With the SC-PT770, they are wireless. Therefore no cables means no clutter. The DVD changer has a 1080p up-conversion function that converts standard definition (720 x 480 pixels) images from DVD sources to High Definition (1920 x 1080 pixels) images. These up-converted signals draw out the maximum performance of an HDMI compatible 1080p HDTV, giving you vivid, sharp and exceptionally detailed high-resolution images to enjoy.
