Introduction About the product
We have designed the A10 to be the world's smallest studio light.
It is designed to provide a beautiful light with great light shaping capabilities and also being incredible easy to use.
We have made the head round to create a circular and natural light pattern. We have a soft and even light fall off that makes it easy to control and set the light creatively. In addition to that we have a range of dedicated Light Shaping Tools that are easily clicked on with a magnetic mount.
The A10 has also AirTTL Remote and receiver built-in, which means it will automatically communicate with other freestanding Profoto lights wirelessly and it can also be used off-camera. This makes it easy to grow in a system and grow with light shaping.
A10 even has a Profoto BLE receiver built-in allowing full control from the Profoto Camera app (available for iOS and selected Android phones). The A10 can be used as an off-camera mobile phone light.

- Slide the hot shoe connector [7] on the A10 into the hot shoe of the camera. Turn the locking mechanism to secure.
- Switch on the A10.
- Turn the dial [13] clockwise to unlock.
- Use the mode switch [10] to select TTL mode (AUTO).
- Take an image with the camera and the flash will adjust its power to get a correct exposure.
- Use the dial [13] to adjust the flash exposure compensation. This can also be done in camera by changing the flash exposure compensation.
TIP: You can at all time switch to manual mode and keep the setting from the last TTL flash. This is extra helpful when you need to lock the flash power and keep it constant.
Note:
TTL is only available in group A-C and group D-F are always manual mode, even if switch [10] is set to TTL mode (AUTO).
For Profoto A10 Air TTL-S, always use the Protective cap [25] when flash is not mounted on the camera or Flash stand [19]. Secure with the locking ring [16].
On-camera use in manual mode
- Follow step 1-3 above
- Use the mode switch [10] to select MAN (Manual) mode.
- Take an image to check the exposure or use the test button [12] and light meter to measure the exposure.
- Use the dial [13] to adjust the light output to your preferences.
TIP: To improve efficiency, use TTL for first shot and then switch to manual to lock the flash power. By doing this you get correct exposure quickly and then you can fine tune flash power in manual mode.
Off-camera use
This describes how to operate an A10 unit off-camera and with an A10 unit on camera as transmitting unit. When A10 is used off-camera together with an Air Remote on camera, please see instruction manual for Air Remote how to adjust the flash from on-camera position.
- Switch on the A10.
- Turn the dial [13] clockwise to unlock.
- Turn on Air and select the same radio channel on the A10 unit as on the transmitting unit on the camera.
- Select a group on the A10 flash. The unit is now set up for off-camera use.
- Take an image to check the exposure or use the test button [12] and light meter to measure the exposure in manual mode.
- Adjust overall flash exposure compensation with dial [13] or in camera menu.
- To adjust an individual light, select the group on the group buttons [11] you like to adjust on the transmitting unit and adjust flash power by rotating the dial [13]. This can both be done in TTL- and manual mode.
- In manual mode, the energy setting can also be done on each unit individually.
Note:
When A10 is used as off-camera unit, the TTL/MAN switch [10] will be overridden. The switch is only valid for triggering an A10 mounted on the camera.
Off-camera mobile mode
It's easy to connect the A10 with the Profoto apps and once you are connected it is even easier and more fun to use the A10. The Profoto apps gives you access to:
- Easy updates and smart remote control using the Profoto Control App. This will always give you the latest A10 updates available at your fingertips and an ability to view and control all A10 settings from your smartphone screen.
- Creative capture using the Profoto Camera app. You can play with light and shadows to create amazing smartphone images lit with your A10.
To connect the Profoto apps to the A10 you need to select BLUETOOTH ON in the settings menu on the A10. Then start the Profoto app and follow the in-app instructions.
Note
When using the Profoto control or Profoto Camera app, the mode switch [10] is disabled and the app will dictate if TTL (AUTO) or manual mode is used regardless if the A10 is mounted on a camera hot shoe or not.
Operation
Mounted in the camera hot shoe, the A10 unit acts both as an on-camera flash and as a wireless extension of your camera to your Profoto off-camera flashes, combining TTL (Through-The-Lens) exposure control with the option to manually adjust and sync your Profoto flashes.
The A10 can also be used as a flash for your mobile camera using the Profoto Camera App. See chapter Profoto Camera and Control apps.
Power on/off
- Push the ON/OFF button [12] to switch on the A10.
- Push and hold the ON/OFF button [12] to switch off the A10.
When the A10 is switched off, the current settings are stored and will apply when the unit is switched on again.
To save battery, the A10 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 this automatically entered standby mode, the display [9] and test button [12] are switched off. To return to operational mode, push any of the A10 buttons or use the camera.
Note:
When the standby and auto power off functions are deactivated, the battery 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 A10 is used off-camera, 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. When using the Profoto control or Profoto Camera app the mode switch will also be disabled.
- TTL mode (AUTO): 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 A10.
- MAN mode: The light output for group A, B, C and D can be controlled manually from the A10.
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.
Flash power scale
The A10 unit has a relative f-stop scale to indicate the flash power level. Full flash power, 100% is always shown as 10. Decreasing 1-fstop means reducing the flash power to half, hence energy 9.0 is 50% of total flash power.
Energy can be adjusted in 0.1f-stop increments.
Operation in TTL mode (Automatic mode)
Adjustment of flash power relations
In TTL mode the camera dictates the light output of the flashes. If more than one light is used the relationship between the flash power levels of group A, B and C can be adjusted. This can, for example, be used to achieve more light on one side of the object.
- Press the A, B or C group button [11] to select the corresponding group.
- When a group is selected, do one or more of the following:
- Use the dial [13] to set the relative light output for the selected group, in relation to the other groups. The relations can be set to +/- 2 f-stops for each group A, B or C.
- Press button [15] to turn on/off the continuous light in the selected group.
- Press and hold the group button [11] to turn on/off the lamp heads in the selected group.
- The display automatically returns to the main menu after a few seconds.
Note:
In TTL mode the numbers displayed for each group only show the relation between the groups. The absolute flash exposure is always set by the flash exposure compensation, either in the flash or in the camera.
Note:
If flashes without Profoto AirTTL support are used in combination with Profoto AirTTL flashes in TTL mode, the flash outputs of the non-TTL flashes are added to the total flash exposure. Such flashes can for instance be used to manually set the exposure on the background.
If a Profoto AirTTL compatible flash is set to group D, E or F, it will be synchronized but not part of the TTL calculation. The flash outputs of these flashes are added to the total flash exposure and can for instance be used to manually set the exposure on the background.
Flash exposure compensation
As an alternative to the flash exposure compensation function in the camera, the A10 can be used to compensate the total flash exposure when in TTL mode.
The A10 must be connected to the camera hot shoe to enable adjusting flash exposure compensation. Ensure that no group is selected and use the dial [13] to adjust the flash exposure compensation +-3.0 f-stops. The selected flash exposure compensation will be applied to lights in all TTL groups (A, B and C).
Operation in MAN mode (Manual mode)
With the A10 set to MAN mode, the light output for the groups A, B, C, and D can be adjusted manually.
- Select group(s) by doing one of the following:
- Press the A, B, C, or D group button [11] to select the corresponding group.
- To select all groups, press one of the group buttons [11] twice. When all groups are selected, the A10 will also control the lights in group E and F (selected on the flash).
- When a group is selected, do one or more of the following:
- Use the dial [13] to adjust the light output for the flash power setting. The adjustment always starts from the current light output setting (displayed as 0.0 above the group indicator) and the adjustment value (e.g. +1.2) is momentarily shown above the group indicator.
- Press button [15] to turn on/off the continuous light in the selected group.
- Press and hold the group button [11] to turn on/off the flashes in the selected group.
- The display automatically returns to the main menu after a few seconds.
Note:
If a light output cannot be set by the flash because it is outside its flash power range, the A10 beeps to signal that the command was not executed. The flash power of all flashes in the selected group then remains unchanged.
Continuous light
To turn on the continuous light on A10, press button [15].
To turn on continuous light on a specific group, first select a group and then press button [15].
When the A10 continuous light is on, a white dot is displayed to the right on the display and/or on the different groups.
Activate/deactivate flash head
The flash head can be deactivated without turning off the power of the A10 unit. This is used when the A10 should work as a remote control for off-camera flashes but no flash itself.
Press and hold the Continuous light button [15] to turn on/off the A10 lamp head.
Note:
The A10 flash head can also be activated/deactivated in the settings menu.
Lock user interface
A long push on the settings button [14] will lock the user interface. This is indicated with a lock symbol. The flash operates normally, although the user interface will not respond to button pushes until unlocked by the user by another long push on the same button.
Manual zoom
The beam angle from the flash can be adjusted at any time to match your preferences. You can for example narrow the light to highlight part of the image.
Rotate the Zoom ring [2] on the flash head clockwise or counter clockwise to change the beam angle.

The following zoom options are available:
- MANUAL: The beam angle is adjusted manually, by turning the zoom ring [2].
- AUTO: The beam angle of the A10 flash light will automatically follow the zooming on the camera.
- The beam angle of the A10 flash can be set to different beam angles, from wide to narrow.
Note:
If a light shaping tool is attached to A10, the beam angle will be different
Continuous light
The continuous light is a constant light source positioned in the flash head. The angle of the light (light spread) will follow the zoom setting on the flash. Use the continuous light to analyze shadows or as a help to position your subject in relation to the flash.
The setting is used to select how the A10 continuous light intensity should correspond with the flash light output.
There are four setting options:
- MIN: The lamp gets the half intensity, regardless of the selected energy level (light output).
- MAX: The lamp gets the maximum intensity, regardless of the selected energy level (light output).
- PROP: The light intensity is automatically adjusted to be proportional to the selected light output (energy level).
- FLICKER FREE: The lamp gets the maximum intensity regardless of zoom setting.
Ready Signal
Ready signaling is used to indicate when the A10 flash is fully recycled.
There are four ready signaling options:
- BEEP: The unit beeps when it is ready to flash again after recharging. This option will also enable key sound.
- DIM: The continuous light turns off after flashing and turns on when the unit is ready to flash again.
- BEEP DIM: The continuous light turns off after flashing. The light turns on and the unit beeps when it is ready to flash again.
• OFF: No ready signal.
The test button light [12] always comes off after flashing and comes on again when the A10 flash is fully recycled.
Control Sounds
The setting can be ON or OFF to enable/disable tactile sounds for Dial and buttons.
Warning Sounds
The WARNING SOUNDS setting can be set to ON or OFF to enable/disable a warning sound for wrong exposure if a flash is fired before the Profoto A10 AirTTL has recycled. A warning is also issued if the
requested flash energy is out-of-range while using TTL. Factory default setting is OFF.

General notes on Profoto Air operation
The Profoto Air channels use specific frequencies in the 2.4 GHz band and have an operating range of up to 300 meters (1000ft). The frequencies are evenly distributed over the entire frequency band. Since each channel uses a different radio frequency, it is possible to select a channel without interference from other photographers using Profoto Air, WLAN/Bluetooth devices, or other radio equipment operating on the 2.4 GHz frequency band.
- Maintain line of sight between Profoto Air units whenever possible.
- When hiding the flash from view, try to not hide it behind or against metal or water-filled objects as this will affect the operating range.

The A10 flash creates a round and even light spread in all zoom positions. In addition, there are specially designed light shaping tools for the A10 that can modify the light quality in various ways.
When A10 is used on camera it can automatically follow the zoom setting on the lens. For creative freedom the beam angle can also be set manually, either in the menu or by rotating the zoom ring [2]. When the zoom ring [2] is used the beam angle setting will automatically go to manual mode. The current beam angle setting is shown in the top of the display [9].
The zoom setting on the flash corresponds approximately to the following focal length coverage for a 35mm camera.
Beam angle setting Focal length coverage
| A10 without accessories | |
| 105 mm | |
| 80 mm | |
| 60 mm | |
| 45 mm | |
| 32 mm |
Clic Dome
The Clic Dome attaches to the A10 unit with the built in magnetic mount. The light quality will be diffused and spread omni directional.

The Clic Dome can also be stacked together with other light shaping tools. For example the optional Gel can be used in combination with the Clic Dome.
Bounce Card
The Bounce Card attaches in the same way as the Clic Dome with a magnetic mount. The application is similar to the Clic Dome but will provide a more directional light quality.
To attach the Bounce Card to its holder, squeeze the sides of the Bounce card slightly and then push it firmly into the holder until the card locks in place.
In most cases the flash is directed against a bouncing surface and the bounce card is directed against the subject.
