connecting and using flash heads
One or two compatible flash heads may be
connected to a Creo generator. Always switch the
generator to 'standby' when fitting or removing any
flash heads. When connecting a flash head to a
Creo pack always ensure that the head connectors
are fully engaged with the locking clips before
turning the generator 'on'.
When a flash head is not fully connected/fitted, the
associated channel LED display will show '- -'.
When a flash head is connected fully the appropriate
channel LED display shows the selected flash
power setting in f-stops.
flash power control
The flash power adjust buttons are used to control
the power output for the associated flash head
fitted to a particular channel. A single press of either
1-Stop or 1/10-Stop flash power adjust button will
adjust the output by a single increment; the flash
power adjustment will be confirmed by a single
short beep (if the sounder is enabled).
By pressing and holding a flash power adjust
button, the generator will adjust the flash power at
an increased rate; every increment adjustment will
be confirmed by a single short beep (if the sounder
is enabled). At the end of the achievable power
range the generator will emit a long continuous
beep until the flash power adjust button is released.
The generator will not alter the actual power level
setting until a short period after the user has
stopped changing the setting; this is to avoid
unnecessary dumping/charging of the flash power.
To manually dump an excess flash power press the
'flash/open test button'.
• The STOPS +/- buttons will adjust the flash
power by 1-Stop steps until the end of the
achievable flash power range is reached.
• The TENTHS +/- buttons will adjust the flash
power by 1/10-Stop steps until the end of the
achievable range is reached.
The maximum flash power available from each
head is dependant on the number of channels used
and the flash power setting of each channel (see
tables opposite for max power settings).
When two heads are fitted and more power is
required from a particular channel than is currently
available, then the setting of the other head must
be decreased i.e. when using a Creo 2400Ws, if
channel A is set to 9.7 then the range of channel
B is 1.0 to 6.5. By lowering the setting of channel
A to 9.4 then the power range of channel B will be
extended from 1.0 to 8.2.
