While showing students the features of the ION console, I put it into 'Client' mode. When I switched back to 'Primary' mode the fader wing (attached 2x20) would not work. The LCD lights up with "Electronis Theatre Controls, Inc." and the LEDs flash on console power up, but buttons and sliders do nothing. I can still access and record faders using virtual faders on screen.
How do I get my fader wing back up?
