Digital Wireless Freedom is a system of professional photographic products, which incorporate a compatible digital radio system, which eliminates the need for a PC sync cable.

Originally integrated in the Profoto Acute2R generator, digital wireless freedom is taken to a whole new level with the Profoto D4. 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 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 Pocket Wizard, the new Profoto D4 can be fired using any model PocketWizard transmitter or transceiver. You can also use the Sekonic L-358 or L-608 light meters, with the Pocket Wizard transmitter enabled, to fire the generator.
