Constant Power Panning
The VST MultiPanner plug-in uses constant power panning laws. This means that the power of a source channel is identical to the power of the corresponding output signal.
Constant power laws ensure that the overall volume, as perceived by the listener, is always the same, regardless of the signal panning. This enables you to move the sound source in the pan area, to disable specific speaker channels, or to use the divergence controls, without experiencing any volume changes.
