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 specifies 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 field 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 field forward. Higher set- tings move it backward.

If the stereo image feels too wide, or there is too much surround sound, move the sound field 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.

Front left speaker	Front right speaker
	20/40˚

Narrow: Select if the listening angle is 20 degrees. Wide: Select if the listening angle is 40 degrees

(default).
