Fine adjustments or further f-stop reductions are done with the BRACKET dial. 17 Energy distribution One head 1. Reduce the energy one f-stop by switching A+B / A<- >B switch to position A<- >B. Further reduce the energy one or two f-stops by halving or quartering the energy with the A-switch. Use the dial BRACKET for fine adjustments and to further reduce the energy by two f-stops. Two heads Symmetrical light distribution 1. Reduce the energy one f-stop by switching A+B / A< -> B switch to position A<- >B. Further reduce the energy one or two f-stops by halving or quartering the energy with the B-switch. Use the dial BRACKET for fine adjustments and to further reduce the energy by two f-stops. Connect one head to the A socket and one head to one of the B sockets. Set the A+B / A <-> B switch in position A<->B. The energy for the two heads is now individually controlled. Reduce the energy one or two f-stops by halving or quartering the energy with the A-switch for the head connected to the A-socket. 18 4. Use the dial BRACKET for fine adjustments and to further reduce the energy by two f-stops. Three heads Symmetrical light distribution 1.
