About Profoto

The Profoto D4 Air 2400Ws Power Pack (90-240VAC) 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 Pro 7 Plus flash head. This 2400Ws pack has outlets for 4 heads, each of which can be controlled separately. It has a built-in radio receiver which offers comfortable radio remote and reliable radio synchronization using the Profoto Air Remote or Profoto Air Sync transceivers (available separately) up to 984' (300 m) away.

It has precise digital readout of each light channel's selected output. Digital photographers will appreciate the 8 f-stop power range for creating 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 (1/4500s to 1/600s) flash durations and recycling times (0.09 to 2.2 seconds).
