If you need more flash output or wish to
perform more sophisticated lighting, you
can increase the number of receiver
units. Simply set an additional receiver
unit to the firing group (A, B or C) whose
flash output you want to increase. You
can increase the number of receiver
units up to 15 units in total.
For example, if you set a firing group with three receiver units to <
4
>,
the three units are controlled as a single firing group A with a large flash
output.

The flash ratio of 8:1 to 1:1 to 1:8 is equivalent to 3:1 to 1:1 to 1:3 (1/2-
stop increments) when converted to number of stops.
