In the Profoto D4, a combination of time proven flash technique with newly invented designs in advanced electronics and microcomputer technology offer total control with maximum flexibility. The Profoto D4 offers digital precision in an easy-to-use package. The Profoto D4, with 4 fully controllable outlets, is equal in flexibility to several individual symmetrical generators.

Many photographers have experienced the hassels of adjusting power by connecting the heads from outlet to outlet. Usually powering the unit off before unplugging the head. The Profoto D4 offers microprocessor controlled light output, all from the control panel. You can even turn off the head, modeling light and flash, without the need to unplug it. The D4 directs the precise amount of power to the head outlet without you having to bother moving connectors and operating switches.

By operating only one power control you can achieve the whole 8 f-stop power range from a single head. D4 optimizes flash duration and color temperature parameters for any of your given power settings or configurations automatically. The Profoto D4 is equiped with mechanical dials to give the user a natural feeling of control when making power adjustments that push buttons and touch pads cannot offer. Each defined and audible step is confirmed by the LED display, which corresponds to a 1/10th f-stop or, if you push while dialing, a full f-stop change. All this frees your mind so you can concentrate on the creative parts of the job.

The easy-to-use controls make it possible to implement four power outlets, individually controlled, with a host of other professional features, without making the unit too complicated to use. Simplicity has always been a feature of Profoto equipment. In addition, the Profoto D4 offers the uncompromised fine-tuning ability on all 4 outlets with color temperature stabilization from flash to flash and over the entire power range.

D4 also has a hybrid, high precision recharging circuit that is more than a 1000 times more precise than conventional techniques. This ensures fast, accurate exposures each and every time. All this and more are computer remote controllable. Complexity inside makes it simple on the outside.
