Symmetrical operation
For symmetrical operation, switch 21 has to be set to the
symbol A + B.
After connecting a flash head to any of the lamp sockets, the full
power of 1200J will be only available if switch 20 and 22 are
both switched towards the symbol 'full circle'. Each 'semi-circle'
setting allows a 300J reduction, and each 'quadrant' setting a
further 150J reduction of the flash power. In total, the maximum
flash power available (1200J) can be dropped by 900J, if both
switches show the 'quadrant' setting. Using dial 8, the flash
power can be gradually decreased by 2 further f-stops in 1/10
increments. Of course, this precise adjustment over 2 f-stops
can be carried out starting from any f-stop setting ('full circle',
'semi-circle'). The flash power is displayed on LED Display 5.
The flash power could be further downregulated by 1 f-stop, if
the operation mode is switched to asymmetric using switch 21.
Asymmetric operation distributes 600J per channel, button 20
allows a maximum 450J reduction ('quadrant' setting) to 150J
and dial 8 a further 2 f-stop reduction to 38J. Thus, flash power
can be adjusted within a range from 1200J to 38J.
In the case of connecting more than 1 flash head to any of the
lamp sockets, the maximum power provided by the power pack
(1200J) is distributed symmetrically to all heads connected. The
flash power can be reduced by a maximum of 900J in the same
manner as described above (both switches 20 and 22 to
'quadrant' setting). The remaining power is distributed
symmetrically over the flash heads connected. A further
stepwise flash power reduction by 2 f-stops is done by using
dial 8.
Asymmetrical operation
For asymmetrical operation button 21 is to be switched towards
symbol A ↔ B. The flash heads are to be connected to channel
A and B. The power pack provides 600J per each channel.
Each channel can be separately switched using switch 20
(channel A) and 22 (channel B). The maximum flash power
available at each channel can be reduced by 450J from
maximum power ('full circle') to ('semi-circle' = minus 300J and
'quadrant' = minus 450J). Using dial 8, a further 2 f-stops
reduction in 1/10 increments can be achieved. This precise
adjustment over 2 f-stops can be carried out starting from any f-
stop setting ('full circle', 'semi-circle'). The flash power is
displayed on LED Display 5 (cannel A) and 11 (channel B),
respectively.
