To make advanced adjustments: Click the Advanced disclosure triangle below the Surround
Panner, and drag the sliders left or right for 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 indicates that it has
been edited.
