PROFOTO D4 GENERATORS
This new flash generator from Profoto is the perfect combination of digital precision and versatility with analogue control and reliability. This gives you the immense possibilities of computer technology and the logical handling of a classical instrument. D4 generators grow with your demands. They are suited to all kinds of sophisticated photography such as still life, interior, people and product shots.

ADVANCED FUNCTIONS
In producing the next generation of flash, design goals were set to give the pack a look and feel of the sophisticated, precise working tool it was conceived to be. From its sleek and ergonomic shape to its responsive controls, the Profoto D4 offers microprocessor regulation for consistent output, whether you work from the pack or control it from your computer. Even though D4 generators offer the most advanced functions, they are easy to use and almost self-explanatory.

FULL DIRECT CONTROL
Designed from the ground up with a commercial photographer in mind, the all-new digital, Profoto D4 flash generators set the standard for consistency and control. The four channel asymmetric system allows direct control of each lamp head. Each head is controlled by a separate knob and corresponding high contrast LED panel. One D4 generator gives you the same possibilities as using 4 independent flash units.

By rotating the knob, 1/10 f-stop adjustments are made. If the knob is pressed while rotating, full f-stop adjustments give the photographer unsurpassed control over an eight f-stop range. In addition, the energy can be asymmetrical distributed over a broad range.

When the light setup is created the power ratio can be individually controlled for each light source by using any of the four separate power controls. For tuning the total exposure after the correct ratio is set, all four channels (power settings) in the generator can be also changed simultaneously by holding down the master button and turning any one of the used lamp head controls.

MAKING OVERALL OUTPUT CHANGES FAST AND EASY
The individual LED displays for each channel can be set by the user to display the flash power in Ws or in relative f-stops and always shows the real output. In the Ws mode, the display indicates the actual watt second output for each individual head. If you prefer, output can be expressed in f-stops, with 100% power being equal to 10 on the scale. With the reduction of one f-stop in power, the display reads 9. Likewise, a 1/10 f-stop change would read 9.1 and so on. And thanks to the microprocessor controlled output, you can be sure that each head will produce exactly the amount of light you want each and every time.

PERFECT PERFORMANCE
Short flash duration and fast recycling are inherent in the design of a Profoto generator. The D4 1200 has a flash duration from1/7500 to 1/1000 sec. and recycling times from 0.07 to 1.20 sec. The D4 2400 offers flash durations from 1/4500 to 1/600 sec. and recyling times from 0.09 to 2.20 sec. In addition, from flash to flash and over the entire power range no shifts of the color temperature or f-stop will occur – even if more than one head is used. This guarantees consistent results on crucial analogue and digital shoots.

In the range of 90-240 V/50-60 Hz, the D4 generators automatically adjust themselves to the mains voltage; only the modelling lamps may need replacing. Thanks to the 4 independent outputs, many jobs can be done with just one generator – a comfortable solution for the “pro on the go”. No matter what and where you shoot, with a Profoto D4 you’ll always have the ideal tool. And because of their solid construction and the use of high quality components, these packs are real work horses, something you can trust in. Profoto D4’s are true all-round generators.
