Operation. Profoto A1
Add to My manuals40 Pages
Profoto A1 is the world's smallest studio light, designed to provide beautiful light with great light shaping capabilities and incredible ease of use. Its round head creates a circular and natural light pattern, while the soft and even light fall off makes it easy to control and set the light creatively. With a range of dedicated Light Shaping Tools that can be easily clicked on with a magnetic mount, the A1 also has AirTTL Remote and receiver built-in, allowing it to communicate with other freestanding Profoto lights wirelessly and be used off-camera.

Operation
Mounted in the camera hot shoe, the A1 unit acts both as an on-camera flash and as a wireless extension of your camera to your Profoto offcamera flashes, combining TTL (Through-The-Lens) exposure control with the option to manually adjust and sync your Profoto flashes.
Power on/off
• Push the ON/OFF button [12] to switch on the A1.
• Push and hold the ON/OFF button [12] to switch off the A1.
When the A1 is switched off, the current settings (except for TTL) are stored and will apply when the unit is switched on again.
To save battery, the A1 automatically enters standby mode after a period of inactivity (selectable via the standby setting) and switches off completely after 90 minutes. These functions can be deactivated via the standby setting.
In standby mode, the display [9] and test button [12] are switched off. To return to operational mode, push any of the A1 buttons or use the camera.
Note:
When the standby and auto power off functions are deactivated, the batteries will drain in approx. 8 hours of inactive use.
Mode selection (TTL or Manual)
Use the mode switch [10] to select TTL or or MAN mode. The mode switch is only active for the on-camera unit. When the A1 is used offcamera, the function of the switch is disabled and the on-camera unit will dictate to all off-camera units if TTL or manual mode is used.
• TTL mode: The camera dictates the light output of the flashes.
The relation between the energy levels for group A-C and flash exposure compensation can be set up from the A1.
• MAN mode: The light output for group A, B and C can be controlled manually from the A1.
Note:
By pressing a group twice all groups will be selected and highlighted. All settings done will now apply to all groups A, B, C, D, E and F.
