I tried it with Generator OFF. It works, but... ...But I can only control the four zones assigned channels, but not the other twelve About the STAGE SETS. Am I wrong here? The way I see it, I can get all 16 channels only on the SYS SETTINGS on or off and of course my STAGE SETS must plan accordingly and assign the channels that I leave turned on here. The last state of that SYS SETTINGS is not stored at power down. Any ideas?
