You are correct. There are mistakes in the pictures of connections it seems with reguard to what the diagrams are named. Totally confusing.

The front heights and front wides are assignable outputs it seems:

Heights or bi-amping mains.
Wides for zone 2 or speaker B amping.

It seems the wides/heights share an amp channel and cannot play at the same time. ie. 11 speaker pairs but only 9 channel amp.

Totally confusing.
