Tex-amp,
Actually, in Pro-Logic the surround channel is NOT processor created - the FRONT
channel is.
In Pro-Logic, there was a discrete monaural surround channel that was matrixed on
top of the front channels. The processor decodes the matrix - but the surround channel
was discrete. However, it was monaural - both rear speakers got the same signal.
The FRONT channel was the processor created channel. Special "steering" circuitry
looked for the common component in the front 2 channels - and assumed that this
common component was the dialog - and created that channel for the front speaker.
