`Sub:

The sub channel is output.

`M/S:

Both the main and sub channels are output.

With this setting, you can broaden the width of the front stereo image when using the Dolby Pro Logic II Music listening mode.

■Dimension

`–3to 0 to +3

With this setting, you can move the sound field forward or backward when using the Dolby Pro Logic II 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.

■Center Width

`0 to 3 to 7

With this setting, you can adjust the width of the sound from the center speaker when using the Dolby Pro Logic II Music listening mode. Normally, if you’re using a center speaker, the center channel sound is out- put by only the center speaker. (If you’re not using a center speaker, the center channel sound will be distrib- uted to the front left and right speakers to create a phan- tom center). This setting controls the front left, right, and center mix, allowing you to adjust the weight of the center channel sound.
