mix sends corresponding outputs ??

SQ5 brand new. Just going over connections and find that Mix 1-4 correspond to outputs 1-4. However mix 5 sends to outputs 5 and 6, Mix 6 to outputs 7 and 8, and Mix 7 to outputs 9 and 10. Is this correct? Or am I missing something?

NEVERMIND assigned in I/O.

mixes 1-4 configured as mono, mixes 5-12 configured as stereo

btw. all connections are patchable
