Profoto Remote Air TTL-N is designed for Profoto B1 and B2 flashes with Nikon TTL support. The trigger weighs 75 g and allows controlling units at distances up to 100 m, with synchronization possible up to 300 m. The Profoto Air radio system is built into many Profoto units, generators, and Hensel D-series lights, but in that case control must be manual without TTL.
This radio system allows remote triggering and control of flash power and modeling light. An unlimited number of heads and generators can be controlled on 8 channels. Profoto Remote Air TTL-N operates at 2.4 GHz, syncs on the first curtain, and supports sync speeds up to 1/250 s. Uses AAA batteries (not included) and can operate up to 30 hours on one set.
