Air Sync Transceiver for Packs and Heads with Built-in Air from Profoto is an eight-channel radio slave transceiver designed to work with any Profoto pack or head with built-in Air radio technology. It will also function with other power packs or monolights without built-in radio slaves by simply wiring a second transceiver to it. The Air Sync can control the firing (but not power levels) of an unlimited number of power packs and monolights on eight channels
Operating from two AAA batteries, at a frequency of 2.4GHz, the Air Sync has a range of 1000′ (300 m). It can sync up to 1/250 second with a focal plane shutter camera, and 1/500 second with a leaf shutter camera. Its triggering speed is over 100 fps.
