3D surround playback
This unit supports virtual 3D surround sound technology called "DTS
Virtual:X". Surround sound can be heard not only from horizontal
directions, but also from varying heights when this unit's 3D surround
mode is enabled, creating a virtual acoustic environment. This ultimately
provides an immersive audio and sound experience by creating a sense
of sounds not only coming from behind, but also above the listener. For
details, see the following:
• "Playback with 3D surround sound/surround sound" (p.27)

box. For details, see the following:
