Two channel equal power panner. Pan2 takes the square root of the linear scaling factor going from 1 (left or right) to 0.5.sqrt (~=0.707) in the center, which is about 3dB reduction. With linear panning (LinPan2) the signal is lowered as it approaches center using a straight line from 1 (left or right) to 0.5 (center) for a 6dB reduction in the middle. A problem inherent to linear panning is that the perceived volume of the signal drops in the middle. Pan2 solves this.
