energy control
The selected energy levels for channel A and B are shown in Flash Light Energy Display
A [6]and B[17].
The f-stop scale reading is default. To show energy in Ws scale, push and hold the Ws
Switch [1].
In f-stop scale, the maximal energy (100%) is shown as 10.0. In Ws scale, the maximal
energy (100%)is2400forPro-8a2400Air and 1200 for Pro-8a1200Air.
The maximal energy for channelA is 10.0 (100%) and the maximal energy for channel B
9.0(50%).The maximal energyin totalfor thetwo channels is 100%.

Modeling light
The Modeling Light Switch [9] is used to turn on/off the modeling light for channelA and
B simultaneously. When the modeling light is on, the Modeling Light Switch knob [9] is
illuminated.
The ModelingLightControl [7]is usedto select one of fourmodeling light alternatives:
• PROP: The modeling light intensity for each lamp head is automatically adjusted to
correspondinproportionin-betweenthegenerators set energyand maximalenergy.
•½PROP:ThemodelinglightintensityisadjustedautomaticallyinproportionasforPROP
whentheenergylevelischanged,butwithhalfmodelinglightintensityofthedesignated

usedtogether; Pro-8a1200Air shall beset to ½ PROP and Pro-8a2400AirtoPROP.

Syncsignaling
The Pro-8a generator can be synchronized with the camera in different ways; via cable,
via Photocell / IR-slave or via the ProfotoAir radio system (LPA radio system available on
special order).Bothsystemscan not be integrated inthesame generator.

• OFF: No ready signal. This setting also disables the sound indicating that a switch is
pressed or a control isturned.
• DIM: The modeling light will be turned off when the generator is being charged, and
turned on again when the charging is completed. This setting also disables the sound
indicating thataswitch ispressed ora controlis turned.

theReady Lamp[10]will beilluminated again.
flash beforeready
The ”Flash before ready”function makes it possible to flash before the recharging of the
generator is ready and fully completed.When a flash is released before the generator is
100% recharged a long ”beep”will sound, indicating an underexposed frame. Naturally
the flash light may not correspond fully to the set value.The underexposure of the frame
may be so small that it makes no significant difference, however it may be informative
to get the feeling of the maximum repetition rate.The underexposure frame may still be
usable if thecatchofthemoment was perfect.

fan cooling & Protection System
The Pro-8a generator is equipped with a very effective fan cooling to prevent over heating.
A microprocessor controlling and supervising the system is integrated for protection and
safety.Dualfanswillnormallyoperateinsilentmodebutwillspeedupautomaticallywhen

Ifthereisriskforoverheatingofthegenerator,causedbyabnormalexternalinfluence,the
protective system will automatically protect the generator from damage.The protective
system will slow down the recharging intervals and eventually the recharging will stop
completely.Afterawhile,whenthetemperaturehasdecreasedsufficiently,thegenerator

Additional information
color temperature
The color temperature of Pro-8a is calibrated to correspond to daylight and, because of
thePiPE(patentpending)technology,itremainsperfectlyconstantandreliablefromflash
to flash and over the entire power range, regardless of the chosen power output and the
number of flash heads used. This makes the Pro-8a generators perfectly suited for all
kinds of critical assignments, even with high-resolution digital cameras and backs. In
combinationwithallactualProflashheadsandlightshapingtoolsthePro-8agenerators
give neutral and extremely stable color. Please note that other factors, like reflections
from surrounding objects and ambient lights with non neutral color characteristic, may
influencethelight colortemperatureand spectra.
12
Combining flash tubes and/or glass covers with different coatings can make distinctive
colortemperatureadjustmentsif needed.
f-stopStability&range
The unique PiPE (patent pending) technology ensures extreme light power stability
from flash to flash as well as over the whole power range.The unique wide power range
offers maximal flexibility for all situation from light power consuming large objects at
large distances to really close ups ex. ProRing2 without overexposure with one and the
sameflashgenerator.Pleasenotethatinfluencefromambientandmodelinglightmakes
measurementofsmall powerlevels difficult.
WArninG
Do not use the light meter’s built-in slave trigger at smaller power levels.Please use a cord and check the shutter
speedtoavoid ambientlightinfluence.
flashDuration
The full power short flash duration has more advantages except from freezing a moving
object. It will also make it possible to use a very short camera shutter speed to cut out
exposureinfluencefrom indoorambient light as well as direct sunlight.
TheflashdurationcanbeshortenedbyreducingthepoweroutputwithFlashLightEnergy
Control A [8] and/or B [19]. The shortest flash duration using a ProHead and a Pro-8a
generator is 1/12000 sec at energy setting 3,0 - 3,2 (19 - 21,5Ws).To shorten the flash
durationathighpower,useaProTwin head.
I.e.ifyouconnectthetwoplugsofaProTwintotheLampHeadConnectorA[4]andB[15]
of a Pro-8a 2400Air generator and use both outlets at 1200Ws, the flash duration is just
1/2200s instead of1/1600s atmaximumpowerwith one ProHead.
