The Profoto D4 2400 R power pack is the latest in the Profoto line of finely designed and crafted sources of power. Compatible with all Acute and Acute 2 Heads*, and the new Pro 7 Plus flash head.
This 2400 w/s pack controls up to 4 heads at once. It has a built in radio receiver by Pocket Wizard -- the Max, which offers almost infinite control over firing times and sequences, with other light sources also used with the Pocket Wizard Max.
It's called Digital, because it has precise digital readout of each light channel's selected output. Photographers working with digital cameras will appreciate the
8 F-Stop power range, creating very subtle lighting effects. Another enhancement is this pack's ability to fire the flash directly from a computer via the pack's USB port.
Sports and theatrical production photographers can make good use of extremely short flash durations and recycling times.
*Note: With 110-117 Voltage: Do not use older Pro-3, Pro-5, Pro-6, PF, PB, or Pro-7 heads. The fans in these heads will operate at slower speed, which may result in overheating.
Note: With 200-240 Voltage: Do not mix the use of Acute/D4 heads with ProHeads. Change the pack's default setting to "Acu" in order to achieve maximum modeling light intensity.
