This Profoto D1 Air 2 Head Studio Kit (500W/s / 1,000W/s) includes one D1 Air 500W/s monolight, one D1 Air 1,000W/s monolight, two 33" white umbrellas and two 8.0' light stands. It all fits in the included Studio Kit Bag. No stone has been left unturned in the provision of tech and convenience features that seem to derive from professional photographers' wish lists. Beneath the sleek matte-black, high-impact polycarbonate finish and highly visible LED readout is strobe design that is digital from the ground up. The 7 stop power range breaks down to 1/10 stop increments providing flexibility, precision and consistency made possible by dual mode SMPS capacitor charging.
A built-in 77 degree reflector (5.12" diameter) maximizes case space and is ideal for umbrella and softbox use. Features that we've come to expect from Profoto over the years: short flash duration, rapid recycling, a bright 300W modeling lamp and heavy-duty cabling are all on-board.
Although supplied with a sync cord, the D1 Air heads are wireless capable, meaning that they have an Air receiver built into them. Optional purchase of the Air Remote Transceiver allows the heads to be remotely triggered from as much as 1,000' (300 m) away. The Air Remote provides 8-channel triggering via hot shoe or mini plug, as well as full-function head control over 8 channels in 6 distinct groups. The D1 heads are also compatible with the Air Sync Transceiver, a simplified version of the Air Remote that offers 8 channels and remote triggering. Additionally, D1 syncing and complete functionality can be wirelessly controlled via your PC or Mac by using Profoto's optional Air USB and Studio Air systems.
Modeling lamp operation is user-selectable: On/Off/Proportional and Free (manual). There is also a selectable flash confirmation (dimming) feature in addition to an audible, fully-recycled tone. The D1 heads are compatible with the full line of widely-acclaimed Profoto light-shaping tools. Finally, the self-sensing multi-voltage circuitry allows you to take the D1 Airs anywhere in the world.
