Pan
The pan control allows the designer to customize how a monaural virtual
channel is mapped to a stereo virtual channel. A pan value of 0 means that the
monaural input virtual channel is attenuated by 3 dB and sent to both the left
and right output channels. The gain (or attenuation) of the matrix crosspoint
is also applied to the input signal as it is mapped to the output signal.
