Sure thing.. Menu/System /DCS set up/... select var 1 channel and hit FXD. Select var 2 and hit FXD... All the channels are now set to fixed mode...
Don't forget the tiu must be turned on (just like a radio or TV) before it can function. Power to fixed 1 or an aux power supply. Yes each channel can control a loop or if you want 4 different small layouts.
