If set to Balance-Fade, allows you to balance the volume or intensity of each channel so that a sound can be heard through any of the speakers in a 2.0 to 7.1 Audio Bus. If set to Steering, allows you to steer the sound’s channels into any of the speakers. The default is Direct Assignment, where FL maps to FL, FR maps to FR, and so on.
The Panner works independently of the number of channels within the source.
Note: The Panner has no effect on an ambisonic sound.
Default value: Direct Assignment
