•

Surround Width: Species how much separation (in dB) is between the decoded surround

signals. At 0 dB, there is complete separation between the center and surround signals, but

each surround signal is mono. To increase the stereo eect in the left and right surround

channels, you can increase the parameter value. This also results in some signal being

diverted from the center channel to the surround channels.

•

LFE Balance: Adjusts the low-frequency eects (subwoofer) signal from –1 (no signal sent to

the LFE channel) to 1 (all signal sent to the LFE channel). When the slider is centered at 0, the

signal is distributed evenly among the ve channels and the LFE channel.

•

Rotation: Rotates all surround signals to the left or right in a circular manner. When the slider

is at the extreme left or right (–180 degrees or 180 degrees, respectively), the surround signal

is rotated to the center channel and the center signal is rotated to the surround channels. At

0 degrees (the center of the slider), there is no rotation.

•

Stereo Spread: Adjusts the amount of stereo eect from the left and right channels to the

center and surround speakers.

•

Attenuate/Collapse: Adjusts the way the panning eect is implemented. At 0, the source

signals are attenuated (meaning that the original channel signals get louder and softer

but are not actually diverted to other channels). At 100, the source signals are collapsed

(meaning that the original channel signals aren’t changed in volume, but instead are moved

to other channels in the panning direction).

•

Center Balance: Adjusts the balance between the center and surround signals. The slider can

be adjusted from –100 (all center signal sent to the surround channels) to 100 (all surround

signals sent to the center channel). At 0, the signal is balanced evenly between the center

and surround channels.

When you make adjustments to advanced parameters, the Pan Mode indicates that it has

been edited.
