Important safety instructions
broncolor flash light systems should exclusively be utilised for professional
photo shootings by qualified personnel. Before starting up your flash light
equipment read carefully all the information in your operating instruction.
The safety instructions in the operating instructions must be strictly
followed!
• Read and understand all instructions before using!
• Remove the transport protection and the packing material
• Close supervision is necessary when any appliance is used near children. Do not
leave the flash light appliance unattended while in use!
• Flash light contains, similar to sunlight, a specific portion of UV radiation!
The undesirable side effects on skin and eyes are considerably reduced by using
flash tubes or protecting glasses with UV safety measures! Nevertheless, taking
pictures at close distances with unprotected skin and eyes should be avoided! Also
avoid eye contact with the light source! The maximum daily UV radiation according to
IEC 60335-2-27 / DIN 5031-10 is: 50 J/m2. This value should not be exceeded!
• With due allowance for heat radiation, the distance between the lamp and a person or
between the lamp and inflammable respectively heat sensitive surfaces should be at a
minimum distance of 1 m!
• The power pack must be switched off to plug-in and to unplug! The lamp plugs and
sockets have mechanical interlocks! When plugging in, ensure that those interlocks
engage completely! To unplug, push down the locking spring below the cable guide
and lift out the plug from the socket!
• Prior to replacing flash tubes, halogen lamps, protecting glasses or fuses, disconnect
the power pack and the lamp from the power supply!
Prior to replacing the halogen lamp or the flash tube, the lamp should cool down for
10 min.!
• broncolor flash light systems should only be equipped with original broncolor flash
tubes, original broncolor combustible and packing material, original broncolor
accessories, and also original broncolor spare parts!
• broncolor power packs, lamps and accessories meet an extremely high safety
standard! When connecting broncolor lamps to power packs of other brands o
r
broncolor power packs to lamp bases or accessories of other brands, integrated
safety measures may become ineffective! Due to different design features and
contact assignment of the lamp plugs of other brands, the user himself/herself may
even be at risk. We offer no guarantee and accept no liability for damages which may
be caused by this type of usage!
• Only lamps which are approved for operation with this power pack should be utilised!
• Only earthed extension cables which are approved for operation with the
corresponding lamp should be utilised!

• To avoid the risk of fire, electric shock or injury to persons utilise exclusively the
accessory recommended by the manufacturer!
• Check that the mains voltage corresponds to the information on the type plate of the
unit!
• The flash light equipment is designed for use in dry conditions and in an ambient
temperature from 0°C to 35°C! The flash light equipment has to be protected from
wetness, condensation, from dripping and splash water, humidity, dirt, sand,
metal chips and exposure to dust!
• Protect the flash light equipment from electromagnetic fields, shock and vibration!
• Protect the flash light equipment from heat and frost! If the power pack freezes
continuous loss of power output and serious technical damage can result!
• Sudden temperature differences can cause condensation water in the unit! In such
situations the equipment must stay for 1 hour in a well ventilated place to acclimatise
to the new temperature before start up!
• Do not operate the units in an environment where there is a risk of explosion!
• The power pack should not be operated in or near water!
Attention: high voltage!
• The power pack and the lamps should not be immersed in water or other liquids!
It could cause an electric shock!
• Remove the transport protection cap on the front side of the lamp before connecting
it to the power pack!
• For safety reasons, never operate the lamp base without the protecting glass in place!
UV-coated protecting glasses or UV-coated flash tubes must be utilised as a
protection against UV radiation for eyes and skin!
• Before operation the lamp has to be fastened on a stand or a suspension device!
The lamp must be locked by tightening the mounting screw!
• Only sand-filled fuses of the type indicated on the safety type plate may be used!
Sand-filled fuses can be identified by their opaque fuse body!
With incorrect fuse protection the halogen lamp may burst!
• Filters or diffusers should not be fastened directly on the flash tube, halogen
modelling lamp or protecting glass!
• Do not operate appliance with a damaged earthed cable. Cables which are damaged
or twisted must be replaced!
• The unit must only be connected to an earthed socket, or an emergency power
generator!
• If an extension cable is necessary, a cable with a current rating at least equal to that
of the appliance should be used. Cables rated for less amperage than the appliance
may overheat. When using a cable reel, it must be completely unrolled before use to
prevent overheating of the cable!
• The unit is suitable for operation with a motor generator provided that the voltage lies
within all the load conditions (including capacitive load) and within the tolerance limit
of 200-264 V respectively 95-135 V! From experience this means that only electronic
stabilised motor generators are to be utilised! When operating on unstabilised motor

4
generators, voltage peaks of 300 V and more have been observed! This can lead to
damages for which we assume no liability!
• Do not operate the lamps inside a bag or a box!
• The ventilation slots on the unit or on the lamp should not be covered!
• Pay attention when laying, clearing away or rolling up cables that the do not contact
hot surfaces or parts of lamps and that they will not be tripped over by persons!
• Do not touch the connection socket for mains cable and lamp outlets on the power
pack and do not poke in it with metal objects!
• Flash tubes, modelling light, halogen lamps and protecting glasses heat up to a high
operating temperature, this also applies to the front side of the lamps! Therefore the
attachments also assume high temperatures! Handle with care! Contact with hot
components can cause injuries!
• Do not come into contact with glass or metal whilst operating the flash light system!
• Let the unit and its connected lamp base cool completely after use and before
packing!
• Always unplug appliance from electrical socket before cleaning and servicing and
when not in use! Never jerk cable to pull the plug from the socket. Grasp plug and pull
to disconnect!
• Dropped or damaged units or lamps must be checked by a specialist before
reconnection!
• To reduce the risk of electric shock, do not open this appliance, but take it to a
qualified service person when service or repair work is required. Incorrect reassembly
can cause electric shock when the appliance is used subsequently!

1. Application Scoro
We are pleased that you have chosen a “Scoro” power pack which is a high-quality state-
of-the-art product in every respect. If used properly, it will render you many years of good
service.
This mains (AC-line) supplied studio flash unit is designed for professional photography.
For your safety use a three-wire extension cable when possible.
2. Start up
2.1 Mains voltage
As a standard feature, all the Scoro power packs are supplied as multi-voltage units.
They automatically adapt to the respective mains voltage.
Scoro power packs A2S and A4S deliver for all operating voltages (85-240 V)
constant 1600 J or 3200 J.
Scoro power packs A2 and A4 can also be operated on 120 V or 100 V.
However, the following limitations apply for 100 V –120 V:
- 800 J are available instead of 1600 J (Scoro A2).
- 1600 J are available instead of 3200 J (Scoro A4).

Attention: Ensure that the operating voltage of the modelling lamp corresponds to the
local mains supply.
2.2 Earthed mains (AC-line)
Whenever possible, connect unit to current supply always using an earthed mains plug.
2.3 Start up
Use the mains (AC-line) switch (1) to power up the unit. During the charging process, the
digital master power display (12) flashes, after which, it becomes continuous.
3. LCD display and menu system
The LCD display presents an absolute innovation. It has never been so easy to activate
that many settings with so few keys. The display is a significant tool, and therefore it is
important that, firstly, you become well acquainted with the structure of the menu system.
The brightness of the user interface can be automatically or manually dimmed dependent
on the ambient light. See LCD setting function “brightness display” (section 11.20).

8
3.1 LCD display menu system
Directly after switching on the unit a start display appears for approximately 5 s with
information about the unit and the owner. Afterwards the unit changes automatically to
the normal operating mode.
By default, the flash duration (t 01) is shown permanently. In addition, depending on
whether the flash duration or the colour temperature have been altered, the display will
adjust and the current value will be indicated.
When delay (dly), sequence (seq), interval (int), alternate (alt) are activated as well as the
studio and unit address (if desired), the corresponding functions will be shown on the
main page. The functions shown in the display give an overview of the most important
activated additional functions of the power pack.
The main menu is called up with the key „menu“ (22). At the same time, at the bottom
edge of the display, a user guide appears, showing the selection keys (21 & 22) each
with their supplementary functions ("▼/▲“, “+/-“, “select“, “cancel“, “quit“, “help”). To
return to normal mode, press the key “menu” (22). Each set value is displayed in a box at
the top of the LCD.
The desired unit functions are selected with the keys "▼/▲“ and confirmed with the key
“select”. The selected function is visually highlighted with a bar.
After selecting the desired function, one reaches the second level. There, the options are
visible within the chosen function, which can then be selected with the keys "▼/▲“ or "-
/+“. The previously stored setting is always indicated in a box at the top line. The function
on which the cursor is currently positioned is marked with a bar. The new setting will
only be set after the select key has been pressed again. The key “quit“ or menu (22)
leads back to the respective higher level. Therefore, it is also possible to quit the
submenu without storing a new setting.

9
3.2 Auxiliary function
The key “help“ activates an info-text for the respective setting. A practical short
description of the addressed functions is stored there. To return to the main menu press
the key “menu“ (22).
4. Energy control
4.1 Scoro A2/A2S
Use the "▼/▲“ keys (9.1/9.2/9.3) to control the flash energy (flash intensity) on each
individual outlet (l, ll & lll) within a range of 9 f-stops. The entire energy, however, cannot
exceed 1600 J. A value of 10 in the digital master power display (12) indicates maximum
intensity, 1.0 minimum intensity.
Whole numbers are full f-stop intervals, decimals indicate 1/10 f-stop steps. Brief
pressure on the keys "▼/▲” (9.1/9.2/9.3/10) runs the power up (or down) by a 1/10 f-
stop interval, prolonged pressure by a full f-stop. The digital display (12) then blinks until
charging or discharging has reached the newly selected level and the „test“ key light (16)
goes out. An acoustic signal announces that the new energy level has been achieved.
4.2 Scoro A4/A4S
Use the "▼/▲“ keys (9.1/9.2/9.3) to control the flash energy (flash intensity) on each
individual outlet (l, ll & lll) within a range of 9.9 f-stops. The entire energy, however,
cannot exceed 3200 J. A value of 10 in the digital master power display (12) indicates
maximum intensity, 0.1 minimum intensity.
Whole numbers are full f-stop intervals, decimals indicate 1/10 f-stop steps. Brief
pressure on the keys "▼/▲“ (9.1, 9.2, 9.3, 10) runs the power up (or down) by a 1/10 f-
stop interval, prolonged pressure by a full f-stop. The digital display (12) then blinks until
charging or discharging has reached the newly selected level and the “test” key light
(16) goes out. An acoustic sound announces that the new energy level has been
achieved.

4.3 Individual energy distribution (asymmetry) & flash cut-off
Scoro power packs incorporate an electronic flash cut-off system for all 3 channels. The
units have three individual lamp outlets which can be controlled, with neutral colour
(Enhanced Color Temperature Control) over the whole range, and with asymmetry up to
6 f-stop increments and independently of each other. The unit allows power selection in
1/10 and whole f-stop increments.
4.4 Colour temperature control / Asymmetry (t 0.1 optimum)
All Scoro units are equipped with an enhanced ECTC-process which ensures that no
colour temperature shifts or double exposure can occur during individual power
distribution. On partial power, the colour temperature of the set energy can be
influenced by relative shifts in increments of 200 K upwards or downwards (see section
11.5). The control range of the colour temperature adjustment is increased when on
reduced power.
Due to the direct dependence of colour temperature and flash duration, t 0.1 is
automatically adjusted.
