consider the following:

You have a multi channel file of a song, each channel is a separate  
instrument: voice, guitar, bass, drums, reverb. Then you have an 8  
channel audio system: Left, Right, Front Fills, Subs, Surrounds, etc.  
The matrix allows you to send your voice and guitar channel the Left,  
Right and front fills at independently controllable levels while  
sending the bass and drums to the Left, Right and Subs, less to the  
front fills, drums perhaps not at all to the FF, Reverb to the Left,  
Right and surrounds, etc. Then, when the front row cannot hear the  
vocal line, you can turn it up in the front fills without affecting  
anything else, etc, etc.
