Allows you to enjoy 5.1(or 6) discrete channels of high quality
digital audio from DTS program sources such as discs, DVD

The Dolby Digital surround format lets you enjoy up to 5.1
channels of digital surround sound from a Dolby Digital
program source. If you play DVDs with “
” mark, you can
enjoy even better sound quality, greater spatial accuracy, and
improved dynamic range.
Use this mode when playing movie or Dolby Digital 2 channel
which carries the “
” mark. This mode provides the
effect of being in a movie theatre or live concert house-an
effect with an intensity which can only be obtained through
DOLBY PRO LOGIC SURROUND. The effect of the
front/back/left/right movement of the sound image, as well as
the sense of fixed position in the sound image, is much
clearer and more dynamic than before.
Dolby Pro Logic II creates five full-bandwidth output channels
from two-channel sources. This is done using an advanced,
high-purity matrix surround decoder that extracts the spatial
properties of the original recording without adding any new
sounds or tonal colorations.
The Movie mode is for use with stereo television shows and all
programs encoded in Dolby Surround. The result is enhanced
soundfield directionality that approaches the quality of discrete
The Music mode is for use with any stereo music recordings.
The Matrix mode is the same as the Music mode except that
the directional enhancement logic is turned off. It may be used
to enhance mono signals by making them seem “larger.” The
Matrix mode may also find use in auto systems, where the
fluctuations from poor FM stereo reception can otherwise
cause disturbing surround signals from a logic decoder. The
ultimate “cure” for poor FM stereo reception may be simply to
force the audio to mono.
This unit can produce a 3D Surround effect, using 3D

and Dolby Digital audio tracks.
