Remote Sync And Control; Auxiliary Functions - Profoto D4 1200 Air User Manual

Remote sync and control

The D4 Air generator can be remotely synchronized and controlled either via the Profoto
Air Remote device or via a computer running the Profoto Studio software.
By the use of groups, selected lamp heads on one or several generators can be controlled
simultaneously. Group selection allows a large light bank with several lamp heads, for
example the background light, to be controlled as one light source.
For remote sync/control using the Profoto Studio software, the D4 Air generator can be
connected to the computer either via the wireless Profoto Air USB transceiver or with a
USB cable. With the Profoto Air USB transceiver multiple generators can be controlled
simultaneously. When deactivating the remote radio control and using a USB cable instead,
only one generator can be controlled.
For remote flash synchronization only, the Profoto Air Sync device or the Phase One/
Mamiya V-Grip Air can be used as well.
Radio operation
The Profoto Air radio system is fully integrated in the D4 Air generator, allowing wireless
remote synchronization and control.
For sync/control via radio, the Profoto Air receiver in the generator must be activated and a
radio channel must be selected. See Remote sync/control setup instructions on page 20.
The Profoto Air system operates over eight specific frequencies in the 2.4 GHz band.
The frequencies are evenly spread over the entire frequency band, to optimize reliable
functionality. The large number of radio channels makes it possible to select a channel that
is not interfered by other photographers using Profoto Air, or by WLAN and Bluetooth devices
and other radio equipment operating on the same widely used 2.4 GHz frequency band.
For best radio operation, pay attention to the following:
• Maintain line of sight between the transmitter (Profoto A ir Remote, Profoto A ir Sync, Profoto
Air USB or Phase One/Mamiya V-Grip Air) and the D4 Air generator whenever possible.
• When hiding the generator from view, try to not place it behind or against metal or water
filled objects as this affects radio range.

Auxiliary functions

The D4 Air generator offers the following auxiliary functions:
• Interval: used for stroboscopic effects
• Sequence: used for multi exposures to increase the flash output
• Delay: used to create wipe effects or for pictures of fast moving objects made with
second curtain synchronization
• Radio: used for wireless remote sync/control, see section Remote sync and control above
