B1X
• Press the READY button [17] to turn ‘BEEP’ on or off.
• Press and hold down the READY button [17] to turn ‘DIM’ on or off.
Wrong exposure alarm
When a flash is released before the unit is ready, there will be a long
beep and the display will blink. These signals indicate that the flash light
does not fully correspond to the set value. The B1X will always continue
to flash even if the set light output cannot be met as the image may still
be usable if the catch of the moment was perfect.
16
The sound alarm is partially deactivated when BEEP is deactivated. If
BEEP is deactivated the sound alarm will only go off if B1X is used in TTL
operation and cannot keep up with the camera in sequence shooting.
Quick burst
Quick burst is an automatically activated function that allows a series
(burst) of flashes to be fired at a faster pace than the B1X can recharge,
without losing light output. The function is only active when the light
output is set to less than full. The length of the burst, in number of
flashes, depends on the repetition rate and the set light output. The
lower the light output is set, the longer bursts can be triggered. Thanks
to this feature, the B1X can trigger up to 20 flashes per second on lower
power output without triggering the “Wrong exposure alarm”. Note that
the accuracy of the light output is slightly less precise when Quick burst
is active.

Handling
Battery mounting
1. To mount the battery, fit the battery pack into the B1X unit and push
firmly until the battery pack locks in place. Make sure there is a
“click” sound, indicating that the battery pack is properly secured.
2. To dismount the battery, first switch off the B1X unit. Press the
Battery release button [9] and pull out the battery pack.
Note!
To prevent damage to battery and/or the B1X housing it is recommended to always remove the battery during
transport. Transport damages are not covered by Profoto warranty.
Battery charging and maintanence
For optimal performance, the battery should be fully charged prior to
usage. The battery can be charged from any charge level. Only use the
Profoto Battery Charger 2.8A, Profoto Battery Charger 4.5A, or Profoto
Car Charger 1.8A.
If the battery is to be stored for a longer period it should be charged
half-full before storing. Never store an empty battery for a longer period
as it may go into a deep discharge state that can damage the cells.
After storing a battery for more than 6 months without using, it is highly
recommended to check the charge level on the battery. If less than
2 of the built-in battery level indicators lights up, the battery should
again be charged to half full before further storage. Always use Profoto
Battery Chargers 2.8A or 4.5A to charge an empty battery that hasn´t
been used for a longer period. The Car Charger 1.8A should not be used
in this case.
1. Dismount the battery.
2. Connect the battery charger to the battery pack.
3. Check that the battery charger indicates that charging is in
progress.
4. When the battery charger indicates that the charging is completed,
it is recommended to disconnect the battery charger and remove
the battery from the charger.

Stand mounting
B1X
1. Fit the Stand adapter [3] to a light stand and secure it with the
Clamp screw [4].
2. The B1X unit can be directed upwards/downwards when the Tiltlock knob [2] is loosened. Fasten the Tilt-lock knob [2] when the
unit is correctly directed.
Mounting Profoto Light Shaping Tools
The B1X’s built-in reflector creates a wide and even light spread with a
18
high output. In addition, the B1X is compatible with more than 120 light
shaping tools, which can be used to shape its already beautiful light
into almost any light you can imagine.
All tools with standard reflector mount (rubber collar with
clasp)
Most reflectors are equipped with Profoto’s unique clamp mechanism,
which makes them easy to mount and allows you to shape the light by
simply sliding the reflector back and forth along the zoom scale [6].
1. Unlock the clasp on the reflector.
2. Slide the reflector onto the B1X. Use the zoom scale [6] to place the
reflector in the desired position.
3. Secure by locking the clasp on the reflector.
Umbrella mounting
Umbrellas are easily mounted by sliding the umbrella shaft into the
Umbrella holder [7]. The umbrella shaft diameter must be between 7
mm and 8 mm in order to fit. When an umbrella is used, it is not possible
to mount an external reflector at the same time.
1. Slide the umbrella shaft into the Umbrella holder [7].
2. After a few centimeters, there will be more friction, then continue to
slide the umbrella shaft a few more centimeters into the Umbrella
holder [7].
www.profoto.com
Page 19
Replacing the Front glass
The Front glass [5] can be replaced with an optional front glass or a
glass dome. The optional dome enhances the “zoom effect” slightly
when using any of the classic Profoto “zoomable” reflectors. The dome
is however not recommended for any of the Profoto OCF light shaping
tools including the OCF Zoom and OCF Magnum reflectors.
1. Switch off the B1X and remove the battery.
2. Wait five minutes to allow the unit to be fully discharged and cooled
down.
3. Gently remove the Front glass [5] by pushing the springs holding
the glass gently to the sides.
4. Carefully fit the front glass/glass dome in place. Make sure that all
springs holding the glass are back in position and securely holding
the front glass/glass dome.
Changing flash tube and Model Light LED
For replacement of the modeling light LED or Model Light LED, contact
your local dealer or distributor for professional service.

B1X
TTL
Profoto B1X supports TTL when used with any of the optional Air
Remote TTL. With a TTL remote mounted in the camera hotshoe, you
may select to let the camera control the flash output fully automatically
without manual metering. Note that TTL is selected/activated on the
remote, not on the flash.
If the camera requires a flash output outside the range of the B1X, the
20
B1X will blink the energy setting on the LCD Display [13] and produce a
long beep to indicate this (it will only beep if the ready signal is turned
on).
The automatic flash exposure indicator [26] ‘AUTO’ is lit every time the
flash output is set automatically by the camera. The indicator is lit for
10-15 seconds after receiving a TTL flash command from the remote.
Important:
Profoto is continuously releasing firmware upgrades to improve and expand TTL compatibility with more camera
brands and the latest camera models. Register your profoto products on profoto.com/myprofoto to get access
to the latest upgrades and to get noticed when new upgrades are available. Find more info on the optional TTL
remotes and a list of compatible cameras on Profoto.com.
HSS
Profoto B1X supports HSS (High-Speed Sync) if used with any of the
optional Air Remote TTL tranceivers. HSS enables shooting with flash
at a faster shutter speed than the fastest external flash sync speed
(x-sync) of the camera. This option can be extremely useful to limit the
influence of ambient light when shooting in bright conditions.
www.profoto.com
Page 21
Depending on your camera brand, HSS is either selected on the remote
or in the camera menu, not on the flash. In the LCD Display [13] of the
B1X a “[ ]”symbol will be visible a couple of seconds after every flash
when HSS mode is used.
Note:
* When HSS is activated, the flash will provide a constant light output during the time when the camera shutter is
open. This means that at a constant HSS flash light output, the flash exposure will change if the camera shutter
speed is changed. It also means that the flash duration will be the same as the camera shutter speed, regardless
if Freeze or Normal mode has been selected on the flash.
* Frequent use of HSS will have an impact on the life-time of the B1X flash tube.
Temperature limit indicator
The temperature limit indicator [25] is lit if the B1X has reached a
temperature level that has activated the built-in over-temperature
protection. When this occurs the performance is limited until the
temperature level is back to an acceptable level.
Check Firmware
1. Switch off the B1X.
2. Press and hold the ENERGY/SETTINGS dial [16] and then press
and hold the TEST button [15] until the B1X switches on.
3. The current firmware version is shown on the Display [13] (for
example: A7).
Upgrade Firmware
We highly recommend that you look for firmware upgrades before you
start using your new B1X.
To access the latest free upgrades you create your personal account
on profoto.com/myprofoto. Once you have an account we highly
recommend you to register your products. By registering your product
you are making sure that you will get noticed when a new upgrade for
your product is available.
Upgrade of firmware is made via the USB port [10], following the
instructions provided in the upgrade application downloaded from
profoto.com/myprofoto. You can always contact your local dealer or
distributor for professional service with each upgrade.
