Mixer capability added to ZP640/641?
I see on the Zone Configuration page of the ZP641 Wizard (Designer version 184.108.40.206) that there are now buttons to select a \"Mix\" option. However, they are greyed out. As I am in the process of designing a system and am evaluating the applicability of a 641 to this particular installation, I do not actually have a 641 hooked up. If I was \"handshaking\" with a new 641, would the \"Mix\" option be available, or is this still in the someday/maybe category?
