Yes, I understand that. But if I connect one SL cable for L and R, and another for C and Sub, how does the controller know which SL cable gets which pair of feeds? When I fooled around a little with the config program (but no SL hardware) it seemed as if the controller SL outputs were not labeled or numbered.

If that's correct, the DSP must send back a request, "we are L/R" or "we are C/B" based on how the speakers are configured...

I had intended to ask this question anyway, before this DSP sub question came up. Just engineering curiosity...
