PocketWizard Wireless Freedom

PocketWizard Digital Wireless Freedom is a system of

professional photographic products, which incorporate a

compatible digital radio system, and eliminates the need

for a PC cord.

Originally integrated in the Profoto Acute2

Rgenerator, digital

wireless freedom is taken to a whole new level with the

Profoto D4 R. Full 32 channel/4 zone triggering offers

photographers creativity and control with a new simpliﬁed

interface.The Profoto D4 is available with a receiver capable

of ﬁring the pack under any condition. With an effective

range of 91 meters (300 feet), the digital radio system cannot

be fooled by other strobes ﬁring, shaded, darkened studios or

blinded by bright lights. Furthermore, since it works on a radio

frequency and not infrared, it works around corners and

through walls. Digital reliability ensures your ﬂash ﬁres

every time. Selecting one of the 32 channels is as simple as

pressing the AUX button and using the MODEL/FLASH

button for the D socket - the LED display automatically

changes from the output to the digital channel display.

Rotating the power control for the “D” socket changes the

channel. If this knob is depressed while rotating, it's possible

to select between the 4 zones or ”quads”. Fully compatible

with all 32 channels used by PocketWizard, the new Profoto

D4 can be ﬁred using any model PocketWizard transmitter

or transceiver. You can also use the Sekonic L-358 or L-558R

light meters with a PocketWizard transmitter module, to

ﬁre the generator.

Profoto D4 – Radio Slave

In the Profoto D4, a combination of ”time -proven” ﬂash technology

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.

Direct Control

Many photographers have experienced the hassles 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. And if

it’s necessary to unplug a head, Profoto’s high-grade lamp

connectors allow this each and every time, even if the

generatoris activated.

By operating only one power control you can achieve the

whole 8 f-stop power range from a single head. The D4

optimises ﬂash duration and colour temperature parameters

for any of your given power settings or conﬁgurations

automatically. The Profoto D4 is equipped with mechanical

dials to give the user a natural feeling of control when making

power adjustments that push buttons and touchpads 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

that you can concentrate on the creative parts of the job.

State-of-the-Art Technology

The easy-to-use controls make it possible to make full use

of four power outlets, individually controlled, with a host of

other professional features, without making the unit too

complicated to use. This has always been a feature of

Profoto equipment. In addition, the Profoto D4 offers the

non-compromised ﬁne tuning ability on all 4 outlets with

advanced colour temperature stabilization from ﬂash-to

ﬂash, over the entire power range and for all heads used.

D4 also has a hybrid, high precision recharging circuit that

is more than 1000 times more precise than conventional

techniques. This ensures fast, accurate exposures each

and every time the unit is called into action and guarantees

the highest reliability. Sophistication inside makes the D4

simple on the outside.
