General notes on wireless operation with Profoto Air
The Profoto Air channels [1-8] use eight 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.
- Keep cables and cords away from antennas.
- Maintain line of sight between the Air Remote TTL-S and the flash unit 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 radio range.

Operating instructions Quick guide
For detailed instructions, refer to the subsequent sections.
Profoto Flash setups
- Set the flash to synchronization via Radio/Air (may differ by flash models).
- Select the same radio channel on all flashes.
- Select the same group (A, B or C) for all lamp heads to be controlled simultaneously.
Air Remote TTL-S
- Remove the protective cap [14] from the hot shoe connector by turning the locking mechanism [13].
- Slide the hot shoe connector on the Air Remote TTL-S into the hot shoe of the camera. Turn the locking mechanism [13] to secure the device.
- Switch on the remote.
- Select the same radio channel on the remote as on the flashes.
- Press the Mode button [6] to toggle between TTL (Automatic) and MAN (Manual) mode.
-
Press the A, B or C button to select the corresponding group.
-
When a group is selected:
a) Press the HEAD button [8] to turn on/off the lamp heads/flashes.
b) Press the MODEL [9] button to turn on/off the modeling light.
c) Press the ENERGY buttons [3] to adjust the energy level for the group in relation to the other groups (TTL mode) or the energy level for the group (MAN mode). Since energy adjustments work differently in TTL mode and Manual mode we recommend to carefully read the detailed instructions for operation in both modes on page 13-16 of this user guide.
- Press the TEST button [5] to manually transmit a sync signal, in order to test the settings.
Power on/off
- Press and hold down the ON button [1] to switch on/off the remote.
- Attach the protective cap when the remote is not used. Secure with the locking mechanism [13].
Note!
The remote automatically turns off after 30 minutes of inactivity. The auto power off can be deactivated by pressing and holding the “Energy +” button [3] when starting the remote. Deactivation is confirmed by two short beeps.
Note that when auto power off is deactivated new batteries will drain in approximately 20 hours of inactive use.
Channel selection
The currently selected channel is shown in the CHANNEL section on the Display [2].
- Press the Channel button [7] repeatedly until the desired channel is displayed.
Sync selection
The selected sync setting (cameras sync setting) is shown in the SYNC section on the Display [2].
- 1st: The flashes fire when the first shutter curtain is fully open.
• Hi-S: HSS is selected.
NOTE:
1st and HSS are selected by the camera automatically based on the shutter speed. Set the camera flash mode to WL when using the remote. Refer to the camera's user guide.
HSS
HSS enables shooting with flash at a faster shutter speed than the fastest external flash sync speed (x-sync) of the camera, all the way down to 1/8000s (may differ between camera models). This option can be extremely useful to limit the influence of ambient light when shooting in bright conditions.
Note!
* During a HSS flash, the flash is pulsing to provide a constant light output during the time when the shutter is open. To ensure a perfect exposure and a stable flash pulse, the flash uses only the upper part of its power range when in HSS Mode. Exact range may differ between flash models.
* Frequent use of HSS will have an impact on the life-time of the flash tube.
*Your remote and AirTTL flash may require a firmware update in order to use this feature. The latest updates and a list of compatible cameras is available on profoto.com/myprofoto. Create your personal account and login to access all new upgrades.
Mode selection (TTL or Manual)
The currently selected mode is shown in the MODE section on the Display [2].
-
Press the Mode button [6] to toggle between TTL and MAN mode.
-
TTL mode: The camera dictates the light output of the flashes. The relationship between the energy levels for group A, B and C can be adjusted.
- MAN mode: The light output for group A, B and C can be controlled manually.
Operation in TTL mode (Automatic mode)
In TTL mode the camera dictates the light output of the flashes. If more than one light is used the relationship between the energy levels for 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 [4] to select the group you want to adjust.
- Use the ENERGY buttons [3] to set the relative light output for the selected group, in relation to the other groups. The relations can be set ±2.0 f-stop for each group A, B or C. Relations should not be confused with exposure compensation. Carefully read all the notes in the end of this section!
- To change the total flash exposure, use the flash exposure compensation function in the camera. Refer to the camera manual for details.
-
Press the Model button [9] to turn on/off the modeling light in the selected group.
-
Press the Head button [8] to turn on/off the lamp heads in the selected group (if the heads in a group are turned off, the relation value for that group will display ‘--’)
- When changing from MAN mode to TTL mode, the previous TTL relation value is displayed.

GROUP A ÷ 1.5 B -- C - 1.0 MODEL MODE TTL SYNC 1st CHANNEL 1Example of remote Display[2] settings in TTL mode operation
The figure shows the Display [2] when:
- TTL mode, 1st-curtain sync and channel 1 are selected.
• Group C is selected to be adjusted. - The relative light output from lights in group A is set to 2.5 f-stops more than lights in group C. (A to +1.5 f-stops and C to -1.0 f-stops).
• Lights/Heads in Group B are turned off.
• The modeling light is turned on in both group A and C.
NOTE:
- Relation values should not be mistaken for flash exposure compensation. To compensate the total flash exposure always use the flash exposure compensation function in the camera. Refer to camera manual for details.
- 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 be 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.
Operation in MAN mode
With the Air Remote TTL-S set to MAN mode, the light output for groups A,B and C can be adjusted manually. By alternating between TTL and MAN mode, you can test your way to the perfect light.
- Press the A, B or C Group button [4] to select the corresponding group.
• To select all groups, press one of the Group button [4] two times. - Use the ENERGY buttons [3] to adjust the light output for the group. The adjustment (increase/decrease) always starts from the current light output setting and the adjustment value is momentarily shown in the ENERGY section on the Display [2].
- Press the Model button [9] to turn on/off the modeling light in the selected group.
