Thanks!
Thanks for showing us your confidence by investing in a Profoto Pro-7 system. For
more than three decades we have sought the perfect light. What pushes us is the convic-
tion that we can even offer the most demanding photographer yet better tools. Still we
know that we will never be able to offer the best light there is; the natural sunlight. But
Pro-7comes very close. It is the best series we have ever manufactured.
Before our products are shipped we have them pass an extensive and strict testing
program. We check that they pass the quality and capacity levels the most demanding
photographers require. For this reason our flash equipment is the standard in most
rentalstudiosinNewYorkandTokyoandthemostrentedflashallovertheworld.Thesys-
tem consists of different generators built and designed to meet the demands of the
most demanding photographers on this planet. Yet the most important thing is the
light you create and it is then essential that the system offers freedom to create your
own light. The Pro-7 heads offer you this possibility in particular. The light source, both
the flash tube and the modelling light, is placed high and free in the flash head. This
makes it easier for you to adjust the light and use your creativity. The reflectors are
moveableandlockeasilyintoplace.Youcanmovethesourceoflighttowardthefocusof
the reflector to reflect the light backwards before it is projected forward. This is not
new,ofcourse.Ourflashheadshavealwaysbeendesignedthatway.Whatisnew,however,
is our new glass cover, which is designed to increase precision. The Pro-7 head and the
Pro-7twinaresuppliedwithafrostedandUV-coatedcoverglass,whichtogetherwiththe
flashtube, producesa colour temperature adapted to daylight colour film. There are
glass covers with varying filtration, for greater changes.

switched between continuous and thermostat-controlled
operations [2]. Please note that when changing modelling
light, flash tube or glass cover the lamp cable must be
disconnected from the generator.
The modelling light has a mini-can socket (E11). The flash
tube has two metal pins. When removing a flash tube, pull it
straight out of the sockets. When inserting a new flash tube,
check that the trigger-wire clasps properly around the flash
tube (please see mounting instructions in package). When
mounting the glass cover, check that both locking springs
connect properly into glass cover holes. In case the head
overheats the modelling light automatically switches off.
When the temperature has dropped sufficiently the modelling
light will switch on again. At the back of the head there is an

Pro-7b head
The Pro-7b head is a small and easily transportable flash
head exclusively designed for the Pro-7b generator. Please
note that when changing modelling light, flash tube or glass
cover the lamp cable must be disconnected from the genera-
tor. The modelling light is a standard 100W lamp with an
E11 socket. The flash tube has two pins. When removing a
flash tube, pull it straight out of the sockets. When inserting
a new flash tube, check that the trigger-wire clasps properly
around the flash tube (please see mounting instructions in
package). The head has no fan. Because of the heat generat-
ed there is a certain limitation to the number of flashes per
minute. At the back of the head there is an opening for
attaching accessories like filters and barn doors.

very quick recycling or to get 4800 Ws out of one single
head. There are two flash tubes in a ProTwin. As the flash
durationisshorteratlowpowersettings,andasonlyhalfofthe
desired power is used in each tube, consequently shorter
flash duration is obtained. For example if you need 1200
Ws, youfire600Wsfromeachtube, andyourflashduration

tion at 1200 Ws with a ProHead is 1/2200 while it is only
1/3200 with a ProTwin. One or two generators can be used.
If, on the contrary, you require 4800Ws from one head you
connect ProTwin to two Pro-7/2400 generators. For the
same reason shorter recycling times is obtained when two
generators are used, as the recycling is faster when the gen-
erators in fact only need to recharge half the energy.

Pro-7 ring
The ring flash fits all Pro-7 generators, and is an entirely
mobilesourceoflight. Theinteriordiameterof100mmpro-
vides plenty of space for professional camera lenses. Since
the camera holder can be tilted forward and backwards, as
well as upwards and downwards, most cameras can be
attached. Thismakesanexcellentsourceoflightincramped
areas, such as the interior of an automobile. Many fashion
photographers also use the ring flash to find new angles and
capture details. The ring flash provides a very distinct,
directed light, but can be complemented by a soft light
reflector, which increases the light source, thereby produc-
ing a softerlight with fewer sharpshadows.

Mains (AC) Connection
Use the included power cable to connect at [1]. The Pro-7 can be connected to all common
mains voltages 90 - 240 Volt, 50-60 Hz. The generator automatically senses which voltage
range is supplied. The green lamp below the handle indicates that the generator is receiving
power from the mains. If not check the mains fuse for faults.
(Pleasealsosee”GasGenerator” on page 24).
Warning:Never use ordinary household extension cords to elongate the power cable.
Connecting Lamp heads
One, two or three lamp heads can be connected to the sockets marked A, B1 and B2 [2]. When

Energy Distribution
When only one lamp head is in use, choose the A socket. Only
theAsocketcanbeusedtoreleasethegenerator’stotalenergy
to one lamp head. Use dial A to adjust energy in 1/3 f:stop
increments from full (1/1) down to (1/8) energy, which is
equivalent to four [4] f:stops.
PLEASENOTE!Whenthedialispositionedtoreleasemore
than 1/2 energy (within the area marked A ONLY) always
point the dial B towards the red indicator [16]. If this is not
done, the indicator lamp will light up. The audible signal will
sound and flash release will not be possible. When the dial is
pointedwithinthe”AONLY”area,theflashisonlyreleasedto
[16]
the lamp head connected to socket A, even if other lamp heads are connected to the B sockets.
When a second lamp head is connected to socket B1 use dial B to adjust energy in 1/3 f:stop
increments, from half energy (1/2) down to one sixteenth energy (1/16), which is equivalent to
four[4]f:stops. WhenthedialispointedwithintheB1ONLYarea, theflashwillnotbereleased
through B2 even if a lamp head is connected.
PLEASE NOTE! To release a flash through B socket(s) dial A must be pointed to less than 1/2
energy. If not, an audible signal will sound and the red lamp [16] will light up at the B dial 1/2
position.WhenathirdlampheadisconnectedtosocketB2usedialBtoadjustenergyin1/3f:stop

Choice of Modelling Light
Thecontrol[15]MOD. LIGHT isusedtochoosethefollowingalternatives:
• OFF Modelling light off

•MAX Modelling light isatmaximum, regardless ofenergy settings
Half proportional modelling light is chosen when a Pro-7a/1200 and a Pro-7a/2400 are used
together. To keep the modelling light proportionally aligned between the two generators, the
Pro-7a/1200 is set to a 1/2 modelling light position, as the flash energy is half of the
Pro-7a/2400.

Connecting Camera and Flash Meter
Thetwosyncsockets[9]allowthecameraandflashmetertobe
connected simultaneously. The 5 meter sync cord can without
restrictions be elongated with a sync extension cable. Con-
necting generators can be done by means of the Profoto sync
interconnection cord or by so called ”hard wiring”.
Recharging
The recharging starts when the push-button [4] is activated. Slow, fast or turbo recharge can
be chosen. When the two push-buttons [13] FAST and (14) TURBO are released, the genera-
tor will recharge slowly. Choose this alternative when the generator is connected to a mains
supply with weak fuses, or if you are uncertain as to how well the mains supply is fused. This is
also the case when weak gas generators are used for recharging (please see ”Gas Generator”
page24).Withthebutton[13]FASTactivatednormalrechargingisobtained.Thisissufficient
for most kinds of photography. The recharging time is 1.1 sec at 1200 Ws and 2.2 sec at 2400
Ws (230 V). When extremely short recharging times are required, as in fashion and sports
photography, or when a motor-drive camera is used press the TURBO [14] button. The gener-
atorwillnowrechargeextremelyfast,in0.7secat1200Wsandin1.4secat2400Ws.Youmay

Photocell
The built-in photocell [8] will sense flash release as well as IR-signals from most IR-trans-
mitters. The photocell is disabled when the button [10] SLAVE is released.
Bracketing
Manual exposure variations are performed as follows:
• PointtheMASTERcontrol[6]atthearrowandreleasean”open”flashbypressingthetest
button[11].
• Set the lighting as you would normally do, determine the appropriate f:stop and shoot the
firstframe.
• TurntheMASTERcontroltothedesiredover-exposure:1/6-4/6ofaf:stopandshootthesec-

Automatic Safety Functions
If the generator overheats for any reason a protective system will automatically start up. The
generator’s recharging intervals will slow down and eventually the recharging will stop com-
pletely.Afterawhile,whenthetemperaturehasdecreasedsufficiently,thegeneratorwillstart
recharging at a normal pace. This automatic protection will only start up under extreme
conditions when the air vents are blocked for some reason. Due to the fast recharging, in
TURBO[14]mode,at”exceptional”rechargingspeed(energyturnover)sensitivepartsofthe
equipment, such as the flash tubes are protected, by lengthening the recharging time.
PLEASE NOTE: The air vents of the generator must never be blocked or covered in any way.
Never store your flash equipment in a car on a hot and sunny day. Never use a generator that is
placed inside a case or transport box. Avoid storing the generator close or below the freezing point,
which can lead to loss of capacity (flash output) and risk of condensation when used in a warmer
surrounding immediately. Do not expose any flash equipment to wet or humid environments or
extreme electro-magnetic fields.

Reliability Testing - The R-Test
The Profoto R-test guarantees that all products leaving the factory meet the very high stan-
dardsrequiredofprofessionalequipmentbyprofessionalphotographers. TheR-testisarigor-
ous performance test that Profoto generators are put through - 720 full power flashes are
released during one hour, which is equivalent to 20 rolls of 35 mm film. After the test the
equipment is examined to see that all parts have kept a normal operating temperature and are
not malfunctioning in any way. All Profoto products are subjected to the R-test prior to being
shipped.

Colour Temperature
The Pro-7 generators are perfectly suited for critical analouge (film) and digital shoots.
The colour temperature is constant and reliable regardless of the energy output chosen with
the dials A, B1 & B2. The colour temperature can be adjusted with the MASTER control [6].
Each 1/6 increment reduces the colour temperature by 50° Kelvin, which means a total down-
scaleof400°Kelvin.
PLEASE NOTE: combining flash tubes and/or glass covers with different coatings can make
even more distinctive colour temperature adjustments.
Flash Duration
The flash duration can be shortened by reducing the energy output with the dials A and B. The
shortest flash duration using a Pro-7 head and a Pro-7a/1200 generator at 1/16 energy is
1/12000sec.
Lamp Heads
The following are suited for Pro-7a 1200/2400:
ProHead
Pro-7 ring
ProTwin
[90.07.09]
[30.05.15]

head plug, align the dots on the plug with the white dot on the generator panel. Secure by turn-
ing the locking ring on the plug clockwise.
Energy Control
The energy output is regulated with the control ENERGY [5]. The energy can be adjusted in
1/6 f:stop increments, from 1/1 down to 1/32 of the total energy (equivalent to six f:stops).
At any change of the energy output the white ready lamp [9] will start flashing indicating that
theenergyneedstobedumpedi.e.bypushingthetestbutton[9].Thegeneratorwillthereafter
be charged to the chosen energy output.
Choice of Modelling Light
The control marked MOD.LIGHT [12] is used to choose the following alternatives:
OFF Modelling light is turned off
1/1
Modelling light is receiving the designated proportional energy at full intensity deter-
minedbythe positionof the ENERGYcontrol [5]
1/2
Modelling light* is receiving the designated proportional energy at half the intensity
determined by thepositionof theENERGYcontrol [5].
MAX Modelling light is at maximum light output regardless of energy setting
When connecting two lamp heads or a ProTwin the modelling light proportionality is
automatically adjusted.
*Thealternative1/2proportionalmodellinglightischoseninthosecaseswhenaPro-7/1200andaPro-7/2400areused
together. To obtain the exact proportionality between the two generators the Pro-7/1200 modelling light has to be set at
1/2, as the flash energy is half of the Pro-7/2400.

Connecting Camera & Flash Meter
Thetwosyncsockets[7]allowthecameraandflashmetertobeconnectedsimultaneously.The
5 M sync cord can be extended without limitations with sync extension cords. Further sync
connections can be made with the Profoto sync interconnection cable or by so called ”hard
wiring”.Aslavesignalfromthephotocellcanbeforwardedthroughthiscabletoanotherflash
generator.
Recharging
The recharging starts when the ON/OFF button is pushed down. The first time the generator is
used after being connected to the mains supply, it will charge to full energy regardless of the
energy control position. This is a safety feature, which is indicated by the ready lamp [9]
flashing. Dump the excess energy by firing a flash and the generator is now ready to be used
with the energy selected. Slow or fast recharging can be chosen. When the button marked
FAST [11] is released, the generator will recharge slowly. Choose this alternative when the
generatorisconnectedtoamainssupplywithweakfusesorifyouareuncertainastohowwell
the mains supply is fused. Press down the FAST button [11] for normal recharging cycles; this
is sufficient for most kinds of photography. The recharging time is approx. 0.8 sec for
Pro-7s/1200 at full energy and 230V. When extremely short recharging times are required,
for instance when operating a motor-drive camera, choose lower energy settings. The lowest
energy setting offers the fastest recharging rate (0.08 sec).

Safety Functions
After having connected the generator to the mains outlet the first charge is always made to
maximum energy for capacitor formation. This is important in order to avoid damage after
leaving the generator unused for some time. If the generator for any reason whatsoever over-
heats, therechargingwillstopcompletely. Afterawhile, whenthetemperaturehasgonedown

tion system will only start up under extreme conditions, for instance when the air vents are
blocked for some reason.
PLEASE NOTE: The air vents of the generator must never be blocked or covered in any way.
Never store your flash equipment in a car on a hot and sunny day. Never use a generator that is
placed inside a case or transport box. Avoid storing the generator close or below the freezing point,
which can lead to loss of capacity (flash output) and risk of condensation when used in a warmer
surrounding immediately. Do not expose any flash equipment to wet or humid environments or
extreme electro-magnetic fields.

Reliability Testing - The R-Test
The Profoto R-test guarantees that all products leaving the factory meet the very high stan-
dards required of professional equipment by professional photographers. The R-test is a
rigorousperformancetestthattheProfotogeneratorsareputthrough-720fullpowerflashes
arereleased during onehour, which is equivalent to20 rollsof35mmfilm.
After the test the equipment is examined to see that all parts have kept a normal operating
temperature and are not malfunctioning in any way. All Profoto products are subjected to the
R-test prior to being shipped.
Colour Temperature
The Pro-7 generators are perfectly suited for critical analouge (film) and digital shoots. The
colour temperature is constant with a variation of a maximum of +/- 75°Kelvin.
PLEASE NOTE: combining flash tubes and/or glass covers with different coatings can make
even more distinctive colour temperature adjustments.
Flash Duration
Reducing the energy output can shorten the flash duration. The shortest flash duration using a
Pro-7 head and a Pro-7s/1200 generator at 1/32 energy is 1/8000 sec. (For more details please
see ”Technical Data” on page 32). If a Pro-7 twin is used a flash duration of 1/12000 can be
achieved with a Pro-7s/1200 unit.
Lamp Heads
The following are suited for Pro-7s 1200/2400:
ProHead [90.07.09]

Recharging
TherechargingstartswhentheON/OFFswitch[12]ispusheddown.Sloworfastrechargingcan
be chosen. When the button FAST [10] is released, the generator will recharge slowly. Push
the FAST button [10] for normal recharging cycles; this is sufficient for most kinds of photog-
raphy. The recharging time is approx. 2.8 sec at full energy. When extremely short recharging
times are required, for instance when operating a motor-drive camera, choose lower energy
settings. The lowest energy setting offers the fastest recharging rate (0.18 sec). The generator
is turned off by pressing the button ON [12] for a minimum of three seconds. The generator
automaticallyturnsoffwhenthecontrolsMASTER[13], MOD.LIGHT[11]andthesyncout-
lets have not been in use for 30 minutes.
Photocell
The built-in photocell [5] will sense flash release as well as IR-signals from most IR-transmit-
ters.ThephotocellisdisabledwhenthebuttonmarkedSLAVE[7]isreleased.Thephotocellcan
also, via cable, trigger off an additional generator.
Signals, Audible & Visible
One of the indicator lights for the battery charge [3] will light up once the generator is turned
on. The charge indicator [3] is up-dated when the generator is turned on or when a flash is
fired. When all lights light up the generator has no charging value - fire a flash. When the

Safety Functions
If the generator for any reason whatsoever overheats, the
recharging will completely stop. After a while, when the
temperature has gone down sufficiently, the generator will
start recharging at a normal pace again. No recharging can
take place when the red light of the battery indicator is on.
This is a safety feature protecting the battery from harmfully
lowdischarging. Therearethreefusesonthebatterycassette.
One is for the charging circuits and two for the battery.
Furthermore the contacts are short-circuit proof.
PLEASE NOTE: Never store your flash equipment in a car on a
hot and sunny day. Avoid storing the generator close or below the
freezing point, which can lead to loss of capacity (flash output)
and risk of condensation when used in a warmer surrounding
immediately. Do not expose any flash equipment to wet or humid
environments or extreme electro-magnetic fields.
Reliability Testing - The R-Test
The Profoto R-test guarantees that all products leaving the
factory meet the very high standards required of professional equipment by professional pho-
tographers. The R-test is a rigorous performance test that Profoto generators are put through
- 360 full power flashes are released during one hour, which is equivalent to 10 rolls of 35 mm
film.
After the test the equipment is examined to see that all parts have kept a normal operating
temperature and are not malfunctioning in any way. All Profoto products are subjected to the
R-test prior to being shipped.

Colour Temperature
The Pro-7 generators are perfectly suited for critical analouge (film) and digital shoots.
The colour temperature is constant with a variation of a maximum of +/- 150°Kelvin.
PLEASENOTE:combiningflashtubesand/orglasscoverswithdifferentcoatingscanmakeeven
more distinctive colour temperature adjustments.
Flash Duration
Reducing the energy output with the control MASTER [13] shortens the flash duration. The
shortestflash durationusingaPro-7 head is 1/3000 sec.
(For more details please see ”Technical Data” on page 41).
Lamp Heads
The ProHead, ProTwin, Pro-7 head, the Pro-7 twin, the Pro-7 ring or the exclusively designed
Pro-7b head can be used. With the ProTwin and two Pro-7b generators 2400 Ws can be
obtained.
