With this setting, you can move the sound field forward or
backward when using the Dolby Pro Logic IIx Music
listening mode. Higher settings move the sound field
backward. Lower settings move it forward.
If the stereo image feels too wide, or there’s too much
surround sound, move the sound field forward to improve
the balance. Conversely, if the stereo image feels like it’s
in mono, or there’s not enough surround sound, move it
backward.

to

With this setting, you can adjust the width of the sound
from the center speaker when using the Dolby Pro Logic
IIx Music listening mode. Normally, if you’re using a
center speaker, the center channel sound is output only
from the center speaker. (If you’re not using a center
speaker, the center channel sound will be distributed to the
front left and right speakers to create a phantom center).
This setting controls the front left, right, and center mix,
allowing you to adjust the weight of the center channel
sound.

The DTS Neo:6 Music listening mode creates 6-channel
surround sound from 2-channel stereo sources. With this
setting, you can specify by how much the front left and
right channel output is attenuated in order to create the
center channel.
Changing the value from “0” to “5” will spread the sound
of the center channel to left and right (outwards).
