Due to the two stage SMPS (Switch Mode Power Supply) technology, the Pro-8a could

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%.  
FlashLightEnergyControlA[8]andControlB[19]areusedtoadjusttheenergylevelsfor  
channelA and B respectively:  
Turnthecontrolclockwisetoincreasetheenergyin1/10f-stopincrementsandcounter-  
clockwise todecrease.  
• Press and hold down the control (abeepwill sound) and turn the control clockwise to  
increase theenergyin1f-stopincrements and counter-clockwise to decrease.  
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  
energy. Half proportional modeling light is used when generators of different sizes are  
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.  
• The two Sync Connectors [2] allow the camera and a flash meter to be connected  
simultaneously.The5metersynccablecanwithoutrestrictionsbeelongatedwithasync

recommendedtobeusedtopreventgroundreferenceinterferencewhenconnectingsync  
cables betweendifferentgenerators.  
ThePhotocell/IR-slave[3]sensesignalsfrommostIRsynctransmittersaswellasfrom

• The Profoto Air remote radio control system is integrated in all Pro-8a generators,  
meaning that the generators are prepared to be synchronized or controlled either viaAir  
Remote,Air Sync orviatheProfotoStudio2computer programandAir USB.  
The Sync Control[5]isusedtocontrolthesync signaling:  
• RADIO:The generatorisset to sync viaradio.  
• SET:Enablessettingofradiochannel and group.  
• OFF:The generatorissettosync viacable.  
• SLAVE:The generatorisset to sync viaphotocell / IR.  
ready signaling  
Readysignalingisusedtoindicatewhenthegeneratoris100%fullycharged.TheReady  
Control [16]isusedtoselectone of fourreadysignaling alternatives:  
• 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.  
10  
• BEEP: A clear ”beep” will sound to indicate that the charging of the generator is  
completed. This setting also enables the sound indicating that a switch is pressed or a  
control isturned.

The versatile recycling speed settings make it possible to efficiently utilize the mains  
powersupplybyadjustingandoptimizingthemaximumpossiblespeedandloadwithout  
blowingfuses.Thegenerator’samperageloadfromthemainspowersupplycorresponds  
proportionally tothespeed setting.  
The SpeedControl [18]isusedto select one of fourrecycling speed settings:  
• 25% The slow recycling speed is four times as long as the MAX recycling speed.This  
alternative shall be selected when the generator is connected to a mains power supply  
with weak fuses,when you are uncertain as to how well the mains power supply is fused  
andwhenweakgasgeneratorsareusedforcharging.Itmayallowtreeorfourgenerators

theReady Lamp[10]will beilluminated again.  
flash beforeready  
The ”Flash before readyfunction 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 ”beepwill 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  
workinginhotsurroundingsorcontinuouslyathigherpowerlevels.Lowerflashenergyusage  
andnormalroomtemperaturewillslowdownthefanspeedstobeassilentaspossible.  
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  
will start recharging at a normal pace.This automatic protection will only interfere under  
extreme conditionssuchaswhen theair vents areblocked.

notice  
The air vents of the generator must never be blocked or covered in any way.Nor should the generator be operated in an  
enclosed small space. Never store your flash equipment in a car on a hot and sunny day longer than 30 minutes.Avoid

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.

WArninG  
Only use Pro-8a on the same petrol-electric generator, use of any other flash model simultaneously will cause  
high voltage and may damage the Pro-8a. Pro-8a itself does not cause gas generators to produce high voltages.
