 There are 
several problems involved in mixing with an additional centre front channel 
for many engineers.The channel itself was originally designed for dialogue 
in matrix cinema surround systems and does not have a direct application in 
music mixing, where a 2-speaker stereo stage is generally, and traditionally, 
employed.Many studio engineers with a background in conventional stereo music mixing 
find that simple panning of a source to the centre-front (CF) channel makes 
it fail to blend in with the stereo mix.
