What are you talking about? Calibration systems calibrate speakers. What happens upstream in the processor to determine what signals go to each speaker is irrelevant.
I think maybe ban25 slightly misstated by saying "runs a frequency sweep on each channel individually". It's more specifically "on each output channel", ie "on each speaker".
If you were feeding some test media into the processor, like when using REW, then you have to worry about what input channels you're using and what modes to get your stuff to individual speakers, but the inbuilt calibration just goes straight to the output channels. So "SW1" or "SW2" or "L". There is no "LFE" on that side.
