Potential connection problems: 976 in a system w/zero 4K gear?

If all 5/7 channels set to Large, should the 976 still output LFE to the sub?

Also has anyone tried setting surrounds to large, leaving LCR set to Small? 975 won’t allow surrounds Large, LR small. 976 “suggests” yes. 975 doesn’t say one way or the other.

Thnx, Tony
