The Profoto D4 Air flash generator is extremely versatile and precise. The D4 Air generator
offers a flexible, fully asymmetric energy distribution to all four lamp sockets. This means
that one D4 Air generator can be used like four separate generators, without the need to
plug or un-plug lamp heads for power changes. The 8 f-stop power range in full or 1/10
f-stop increments allows precise light adjustments, the use of high ISO speeds and even
large aperture techniques to create pictures with a shallow depth-of-field. At the same
time they offer enough power to master jobs with a higher light demand.
The outstanding power and color stability of the D4 Air generator makes it easier to create
technically perfect images. A wide range of flexible light shaping tools allows adjustment of
the light characteristics precisely to the photographer’s style and needs. Despite advanced
technology and integrated auxiliary functions, the D4 Air generator is surprisingly easy to
use. All settings can be done directly and every adjustment is displayed immediately. It is
possible to activate and deactivate each head separately by the push of a button.
The integrated Air system offers a reliable radio sync and comfortable radio remote control
– either with a Profoto Air Remote hand unit or with the Profoto Studio software for Mac or
PC together with a USB cable or an optional wireless Air USB transceiver.
The D4 Air product family includes the following flash generators:
• D4 1200 Air
• D4 2400 Air
• D4 4800 Air

Functionality
Power supply
The D4 Air generator can be connected to 100-240VAC, 50-60Hz. The generator
automatically senses and adapts to the voltage and frequency supplied.
WARNING:
Never use ordinary household extension cables to elongate the power cable, since they may overheat. Always
unwind all cable if an extension cable is used.
Lamp head configuration
The D4 Air generator is designed to – by configuration – be compatible with either the
Acute/D4 series or the Pro series of heads. The default configuration is compatibility with
the Pro series of heads. The configuration is easily changed; see instructions on page 17.
When the D4 Air is configured for the Pro series of heads, there is no need to change the
modeling lamp when using Pro heads. The modeling light is powered correctly by the
generator – worldwide.
When the D4 Air is configured for the Acute/D4 series of heads, it is important to use
modeling lamps that correspond to the local mains voltage: 100V modeling lamps in
100V markets, 120V modeling lamps in 110-120V markets and 240V modeling lamps in
200-240V markets.
PLEASE CHECK THE CONFIGURATION OF THE GENERATOR, THE MODELING LAMPS AND
THE MAINS VOLTAGE BEFORE CONNECTING A FLASH HEAD!
Energy distribution
The D4 Air generator offers a flexible, fully asymmetric energy distribution to all four lamp
sockets. Non-used sockets are automatically deactivated.
When only one lamp head is used, it should be connected to Lamp Head Socket A or B [9].
These sockets can be used to release the total energy (100%) of the generator to one lamp
head. With one head connected to socket C, 50% of the total energy can be released and
with one head connected to socket D, 25% can be released.
When two or more lamp heads are connected, the maximal energy level in total for all
heads is of course 100%. It is not possible to select a higher energy level setting than the
maximal; when the upper limit is reached, the energy level setting shown in the Energy
Display [10] will stop at the maximal value even if you try to increase the energy level.
NOTE:
Since the D4 Air works with separate capacitor banks for best color and f-stop stability, about 1/10 f-stop of the total
energy may not be available at some settings when using two or more lamp heads.
www.profoto.com
The energy level is by default displayed in f-stop scale. To show the energy level in Ws
scale, press the Ws/f-stop Button [11].
In f-stop scale, the maximal energy (100%) is shown as 10.0. In Ws scale, the maximal
energy (100%) is 4800 for D4 4800 Air, 2400 for D4 2400 Air and 1200 for D4 1200 Air.
The Energy Controls [13] are used to adjust the energy levels for the corresponding head:
• Turn the control clockwise to increase the energy in 1/10 f-stop increments and
counter-clockwise to decrease the energy.
• Press and hold down the control and turn the control clockwise to increase the energy
in 1 f-stop increments and counter-clockwise to decrease the energy.
• To adjust the energy level for all heads at the same time, press and hold down the
Master Button [14] and use the Energy Control [10] of any of the active heads.
A double beep indicates that the maximal energy level setting is reached.
Since the generator has auto dump functionality, there is no need to trigger a flash to
discharge the generator when the energy level is lowered.
Modeling light
The Head/Model Buttons A-D [12] are used to turn on/off the corresponding modeling light.
The Modeling Light Button [19] is used to turn on/off all the modeling lights at the same time.
The D4 Air generator has a soft start function of the modeling light, which extends the
lifetime of the halogen lamps. This means that the modeling lights start with a slight delay.
The Modeling Light Button [19] is used to select one of the following modeling light
alternatives:
• MAX: The modeling lamps will get maximal intensity, regardless of the energy level
settings of the heads.
• PROP: The intensity of the modeling lights will be proportional to the energy level
setting of the corresponding heads.
• MAX PROP: The modeling light for the head with the highest energy level setting will
get maximal intensity. The modeling light intensity for the rest of the heads will be
proportional to the energy level of the head with highest energy.
• ½ PROP: The modeling light intensity will be proportional to half the energy level setting
of the heads. This is useful when mixing generators of different sizes. For example, a
D4 4800 Air shall be set to PROP and a D4 2400 Air to ½ PROP when used together.
The Modeling Light Indicators [20] show the current modeling light setting.

Recharging
The recharging speed is controlled by pressing the Recharging Speed Button [21]:
• When the Recharging Speed Button [21] is unlit, the generator will recycle at normal
speed. Select this alternative when the generator is connected to mains supply with
weak or unknown fuses.
• When the Recharging Speed Button [21] is lit, the recharging will be faster.
The white Ready Lamp [18] will turn on when the generator is fully charged and ready to flash.
To prevent incorrect exposures, it is not possible to release a flash while the generator is
charging. If you try, a long beep will indicate that no flash was released.
Ready signaling
Ready signaling is used to indicate when the recharging of the generator is completed.
The Ready Mode Button [17] is used to select one of the following ready signaling
alternatives:
• OFF: No ready signal.
• DIM: The modeling light will be turned off while the generator is being charged.
• BEEP: A short audible signal will indicate that the charging of the generator is
completed.
• BUZZ: An audible signal with several “beeps” will indicate that the generator is being
charged.
• BEEP-DIM: The modeling light will be turned off while the generator is being charged
and a short audible signal will indicate that the charging of the generator is completed.
• BUZZ-DIM: The modeling light will be turned off and an audible signal with several
“beeps” will indicate that the generator is being charged.
The Ready Mode Indicators [16] show the current ready signaling setting.
Synchronization
The D4 Air generator can be synchronized with the camera in different ways:
• The two Sync Sockets [4] allow the camera and a flash meter to be connected
simultaneously. The 5 meter sync cable can without restrictions be elongated with
a sync extension cable. Generators can be connected by means of the Profoto sync
interconnection cord.
• The Photocell/IR slave [5] will sense other flashes as well as IR signals from most IR
sync transmitters. The Slave Button [6] is used to activate (lit button) and deactivate
(unlit button) the Photocell/IR slave.
• Synchronization via the Profoto Air radio system, see section Remote sync and control
below.
www.profoto.com
By the use of groups, selected lamp heads on one or several generators can be controlled
simultaneously. Group selection allows a large light bank with several lamp heads, for
example the background light, to be controlled as one light source.
For remote sync/control using the Profoto Studio software, the D4 Air generator can be
connected to the computer either via the wireless Profoto Air USB transceiver or with a
USB cable. With the Profoto Air USB transceiver multiple generators can be controlled
simultaneously. When deactivating the remote radio control and using a USB cable instead,
only one generator can be controlled.
For remote flash synchronization only, the Profoto Air Sync device or the Phase One/
Mamiya V-Grip Air can be used as well.
Radio operation
The Profoto Air radio system is fully integrated in the D4 Air generator, allowing wireless
remote synchronization and control.
For sync/control via radio, the Profoto Air receiver in the generator must be activated and a
radio channel must be selected. See Remote sync/control setup instructions on page 20.
The Profoto Air system operates over eight specific frequencies in the 2.4 GHz band.
The frequencies are evenly spread over the entire frequency band, to optimize reliable
functionality. The large number of radio channels makes it possible to select a channel that
is not interfered by other photographers using Profoto Air, or by WLAN and Bluetooth devices
and other radio equipment operating on the same widely used 2.4 GHz frequency band.
For best radio operation, pay attention to the following:
• Maintain line of sight between the transmitter (Profoto Air Remote, Profoto Air Sync, Profoto
Air USB or Phase One/Mamiya V-Grip Air) and the D4 Air generator whenever possible.
• When hiding the generator from view, try to not place it behind or against metal or water
filled objects as this affects radio range.
Auxiliary functions
The D4 Air generator offers the following auxiliary functions:
• Interval: used for stroboscopic effects
• Sequence: used for multi exposures to increase the flash output
• Delay: used to create wipe effects or for pictures of fast moving objects made with
second curtain synchronization
• Radio: used for wireless remote sync/control, see section Remote sync and control above
www.profoto.com
D4 1200 Air, D4 2400 Air, D4 4800 Air
Remote sync and control
The D4 Air generator can be remotely synchronized and controlled either via the Profoto
Air Remote device or via a computer running the Profoto Studio software.
13
D4 1200 Air, D4 2400 Air, D4 4800 Air
14
The Set Button [7] is used to enter and exit auxiliary mode. The generator operates as
normal also when in auxiliary mode.
In auxiliary mode, the Head/Model Buttons A-C [12] are used to activate/deactivate the
auxiliary functions Interval, Sequence and Delay. The Energy Controls A-C [13] are used
to select the auxiliary functions settings (for Radio settings, see instructions on page 19):
• Interval: Turn Energy Control A [13] to select the time interval (0.1-60 s) between the
flashes. For changes in larger increments, press down the control while turning. To use
the Interval function, the Sequence function (see below) must first be activated (min 2
flashes).
• Sequence: Turn Energy Control B [13] to select the number of flashes (2-60). For
changes in larger increments, press down the control while turning.
• Delay: Turn Energy Control C [13] to select the delay time (0.1-60 s) before the first
flash. For changes in larger increments, press down the control while turning.
If one or several of the auxiliary functions are activated, the Auxiliary Functions Display [8]
repeatedly shows the settings for the activated functions.
If none of the auxiliary functions are activated, the Auxiliary Functions Display [8] shows
the radio settings.
NOTE:
Always check the optimal time delay by taking test exposures. All cameras have different release delays and the
effect depends on the speed and moving direction of the subject. The following list is a rough basis for your own
tests to create wipe effects:

Memory function
The current settings (energy level, modeling light, ready signaling, sync/remote and radio
settings) are automatically saved in the memory of the generator (memory A). Chosen
settings for auxiliary functions are also saved automatically, but they have to be activated
again after the generator has been turned off.
In addition to the automatic saving, it is possible to save up to three combinations of
settings in memory B-D. This makes it easy to repeat even the most complex setups.
When recalling saved settings from memory B-D, auxiliary functions are directly activated.
At start up, the D4 Air generator always applies the settings that were in use before the
generator was turned off. To apply the settings in memory B-D, the settings have to be
recalled from the memory. For instructions on saving/recalling, see page 20.
Automatic safety functions
The D4 Air generator is equipped with an effective cooling and safety system. The
integrated fan will automatically start running when the generator is operating at higher
energy levels or when the generator is used in hot environments.
If there is risk for overheating of the generator, caused by abnormal external influence, 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. After a while, when the temperature has decreased sufficiently, the generator
will start recharging at a normal pace. This automatic protection will only interfere under
extreme conditions such as when the air vents are blocked.
If a defective flash head – for example with a broken or misfiring flash tube – is used, there
will be a long beep signal and “- - - -” will be displayed in the corresponding Energy Display
[10] after the release of a flash to indicate malfunction/underexposure.
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 D4 Air 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.

Test function
The Test Button [18] is used to test that all light settings are correct and that the functionality
is as expected. When the Test Button [18] is pressed, the generator will flash and the Ready
Lamp [18] will turn off while recharging. When the recharge of the generator is completed,
the Ready Lamp [18] will turn on again.

Additional information
Color Temperature
The color temperature of D4 Air is calibrated to neutral daylight. Thanks to Profoto’s
“Hybrid Flash Technology” the color temperature remains perfectly constant and reliable
from flash to flash over the entire power range, regardless of the selected energy levels
and the number of flash heads used. This makes the D4 Air generators perfectly suited
for all kinds of critical assignments, even with high-resolution digital cameras and backs.
In combination with all actual Profoto flash heads and light shaping tools, the D4 Air
generator gives neutral and extremely stable color. Please note that other factors, like
reflections from the surrounding and lenses with different color characteristic, may also
affect the color of the picture.
Combining flash tubes and/or glass covers with different coatings can make distinctive
color temperature adjustments if needed.
f-stop stability
Profoto’s “Hybrid Flash Technology” offers constant power output from flash to flash. This
ensures stable and repeatable results, which is essential when D4 Air generators are used
in combination with Multi Shot backs or for 3D pictures. The power stability of the D4 Air
generators is in fact better than the repeat accuracy of most flash meters.
Flash duration
The flash duration can be shortened by reducing the power output. The shortest flash
duration using an Acute/D4 head and a D4 1200 Air generator at lowest energy is 1/7500
s. To shorten the flash duration even more at a given light setting, use an Acute/D4 Twin.
For example, if you connect the two plugs of an Acute/D4 Twin to the Lamp Head Sockets A
and B [9] of a D4 1200 Air generator and select 600 Ws on both outlets, the flash duration
will be just 1/2600 s instead of 1/1000s at maximum power with an Acute/D4 head.
Petrol-electric generators
All petrol-electric generators can produce voltage peaks that may damage electronic
devices. If a D4 Air generator is powered with a petrol-electric generator distributing
190-240V, a separate Profoto ProGas2 device (protecting against dangerous high voltage)
must be used for each connected generator. To power one D4 Air generators, a 3000 W
petrol-electric generator is recommended; for two D4 Air generators, a 6000 W petrolelectric generator, etc.
NOTE:
Voltage peaks of petrol-electric generators can shorten the lifetime of the modeling lamps. Because of that it is
recommended to use the modeling light in the ½ PROP mode.

Old Profoto heads
The D4 Air generator can be used with old Profoto heads, such as the Acute2 series of
heads, PF heads, PB heads, Pro-6 heads and Pro-7 heads. However, Profoto does not
recommend use of old Acute PAB and Acute Alfa heads (AB or ABS).
NOTE:
When equipped with a 220-240V/50Hz modeling light, PF, PB, Pro-6 and Pro-7 heads can be used at 220-240V/50Hz.
However, Profoto does not recommend the usage of these heads with the D4 Air generator at 100-120V, because the
fan will not work properly which may lead to overheating problems.
