Advanced Setup—Continued
The Audio Adjust functions are explained below.
Input Channel Settings
Multiplex
This setting determines which channel is output from a
stereo multiplex source. Use it to select audio channels
or languages with multiplex sources, multilingual TV
broadcasts, and so on.
Main: The main channel is output (default).
Sub: The sub channel is output.
Main/Sub: Both the main and sub channels are output.
Mono Input Ch
This setting species the channel to be used for playing
any 2-channel digital source such as Dolby Digital, or 2-
channel analog/PCM source in the Mono listening
mode.
L+R: Both the left and right channels are output
(default).
Left: Only the left channel is output.
Right: Only the right channel is output.
PL II Music Mode Settings
These settings provide for playing any 2-channel digital
source such as Dolby Digital, or 2-channel analog/PCM
source in the PLII Music listening mode.
Panorama
With this function, you can broaden the width of the
front stereo image when using the Pro Logic II Music
listening mode.
On: Panorama function on.
Off: Panorama function off (default).
Dimension
With this setting, you can move the sound eld forward
or backward when using the Pro Logic II Music listening
mode. It can be adjusted from 3 to +3 (default is 0).
Lower settings move the sound eld forward. Higher set-
tings move it backward.
If the stereo image feels too wide, or there is too much
surround sound, move the sound eld forward to
improve the balance. Conversely, if the stereo image
feels like it is in mono, or there is not enough surround
sound, move it backward.
Center Width
With this function, you can adjust the width of the sound
from the center speaker when using the Pro Logic II
Music listening mode. Normally if you are using a center
speaker, the center channel sound is output by only the
center speaker. (If you are 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 set-
ting controls the front left, right, and center mix, allow-
ing you to adjust the weight of the center channel sound.
It can be adjusted from 0 to 7 (default is 3).
Neo:6 Music Mode Setting
Center Image
The DTS Neo:6 Music listening mode creates 5.1-chan-
nel 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 cre-
ate the center channel. It can be adjusted from 0 to 5
(default is 2). This setting is unavailable if no surround
speakers are connected.
When set to 0, the front left and right channel output is
attenuated by half (6 dB), giving the impression that the
sound is located centrally. This setting works well when
the listening position is considerably off center. When
set to 5, the front left and right channels are not attenu-
ated, maintaining the original stereo balance.
T-D Listening Setting
Listening Angle
With this setting, you can specify the angle of the front
left and right speakers relative to the listening position.
Processing for the Theater-Dimensional listening mode
is based on this setting. Ideally, the front left and right
speakers should be equidistant from the listening posi-
tion and at an angle close to one of the two available set-
tings.
Narrow: Select if the listening angle is 20 degrees.
Wide: Select if the listening angle is 40 degrees
(default).
20/40˚
