• Make advanced adjustments: Below the Surround Panner, click Show in the
Advanced section, then drag the sliders to adjust any of the following parameters:
• Original/Decoded: Adjusts the balance between the original and decoded signals.
The slider can be adjusted from –100 (original signal only) to 100 (decoded
center and surround signals only). At 0, the signal is balanced evenly between the
original and decoded signals.
• Ambient/Direct: Adjusts the balance between decoded surround and center
signals. The slider can be adjusted from –100 (surround signal only) to 100
(center signal only). At 0, the signal is balanced evenly between the center and
surround signals.
• Surround Width: Specifies 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 effect
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 effects (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 five 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 effect from the left and right
channels to the center and surround speakers.
• Attenuate/Collapse: Adjusts the way the panning effect 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 setting
indicates that it has been edited.
