DTS Neo:6 Music Mode Setting
� Center Image 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. It can be adjusted from 0 to 5 (default value is 2). This setting has no effect if no center speaker is 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 attenuated, maintaining the original stereo balance.

The Audio Adjust settings 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. M/S: Both the main and sub channels are output. � Mono Input Ch This setting determines which channel is output when the Mono listening mode is used with a stereo source. L+R: Both the left and right channels are output (default). L: Only the left channel is output. R: Only the right channel is output.

T-D Listening Angle Setting
� Lstn Angl (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 position and at an angle close to one of the three available settings.

The default value is 0. It can be adjusted from �3 to +3. Higher settings move the sound �eld forward. Lower settings move it backward. If the stereo image feels too wide, or there�s too much surround sound, move the sound �eld 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. � Center Width With this setting, you can adjust the width of the sound from the center speaker when using the Pro Logic II Music listening mode. Normally, the center channel sound is output by only 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 adjusts the front left, right,

Narrow: Select if the listening angle is 20 degrees. Middle: Select if the listening angle is 30 degrees (default). Wide: Select if the listening angle is 40 degrees.

Multichannel Subwoofer Setting
� SW Sens On some DVD players, the signal from the multichannel subwoofer output is 15 dB higher than normal. You can change the subwoofer sensitivity to match your DVD player. Note that this setting only affects signals connected to the SUBWOOFER input jack of the multichannel DVD input. You can select 0 dB (default), +5 dB, +10 dB, or +15 dB. If you �nd that your subwoofer is too loud, try the +10 dB or +15 dB setting.
