Air Remote TTL-N
For B1 Air battery-powered flash head
Profoto's Air Remote TTL-N transmitter for their B1 Air battery-powered flash head enables wireless triggering and TTL remote control. Operating on the 2.4 GHz bandwidth, it has 8 frequency channels with 3 groups per channel and a range of up to 330' for TTL triggering and 1,000' for normal triggering. Each channel has power ratio capability of +/- 2 stops. If you prefer to use manual you have +/- 9 stops power variation. It also includes modeling light, unit shut-down and first or rear curtain control. Both the TTL-N and the B1 500 Air TTL have mini-USB connectors for firmware updates directly from Profoto's website, such as High Speed sync which allows sync speeds as short as 1/8,000 sec. The Air Remote TTL-N will also trigger non-TTL Air heads and packs from Nikon cameras but without the TTL feature.
