The following audio formats are supported by the listening
modes.
This is mono (monophonic) sound.
This is stereo (stereophonic) sound. Two
independent audio signal channels are reproduced
through two speakers.
This is 5.1-channel surround sound. This surround
system has five main channels of sound and a sixth
subwoofer channel (called the point-one channel).
This is 7.1-channel surround sound. This is a
further sound enhancement to 5.1-channel sound
with two additional speakers that provide greater
sound envelopment and more accurate positioning
of sounds.
This is DTS-ES surround sound. This surround
system can produce a discrete or a matrix-encoded
sixth channel from existing DTS 5.1 encoded
material.
This is Dolby Digital EX surround sound. This
provides a center back surround channel from 5.1-
channel sources.
