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!

3
• 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!

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).

7
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.

10
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.

11
5. Lamp outlets
The lamp outlets of the Scoro units are marked with the numerals 1 – 3.
Lamp plugs and sockets have a mechanical locking device to prevent them from
accidentally coming loose. When plugging in, ensure that the front part of the plug is
inserted first, and that the rear locking device locks completely into place. To release,
press down the locking device spring under the cable guide and lift out the plug from the
socket. The power pack must be switched off whilst plugging in and unplugging.
Each outlet may be switched individually (7.1/7.2/7.3). The digital power distribution
display (11) indicates the set energy of each individual lamp. The digital master power
display (12) indicates the total energy control range of all the connected or activated
lamps.
It is unnecessary to disconnect a lamp when not in use, simply deactivate it by using the
lamp outlet on/off switch.
Energy can be asymmetrically allocated to the individual lamps until the maximum
energy has been achieved. If an additional lamp is connected, and should the other
lamps already be using the maximum energy, no more energy can be allocated to the
newly connected lamp.
5.1 Meaning of the digital displays (11)
Example with lamp energy “8.7”:
• “8.7“ blinks flash monitor has detected a misfire
• „—„ lamp connected but switched off
• „ „ no lamp connected
• „-o„ no energy allocation possible (the entire energy has already been
used up by other lamps)
6. Modelling light
The "mod" key (15) switches on the modelling lamp for all connected lamps. When
switched on, the blue LED next to the “mod” key lights up. The lamps have also an
additional modelling lamp switch. Furthermore, it is possible to operate the modelling
light proportionally (section 6.1) and adapt it to the various maximum outputs of
broncolor power packs.
Pressing the "mod" key (15) (1 s. long) when the modelling lamp is on, will give direct
access to the "full" mode. To return to the previous mode briefly press "mod" again.
Attention: Please ensure that the modelling lamp voltage corresponds with the local
mains (AC-line) voltage.
6.1 Proportionality
The modelling light brightness can be set proportionally to the flash intensity.

12
Stages prop1, prop2, prop3, prop4 and prop5 are used to adapt the modelling light
brightness of power packs with different output. The setting “modelling light
proportional” duly allows for the output set, the number of lamps as well as a possible
asymmetrical energy distribution of the Scoro power packs.
Proportionality is guaranteed if the identical operating mode has been set for all power
packs. The higher the digit, the brighter the modelling light.
The following operating modes are possible:
"propmax" When working with only a single power pack (in asymmetrical operation);
using the setting “p.max“, the modelling light of the lamp with the highest
flash energy operates at full output, and the other lamps will be
proportionally dimmed, in accordance with their power settings.
"full" All lamps with full modelling light, independent of flash output, type of
power pack and output distribution.
"low" Lighting level reduced for all lamps to reduce power consumption and
extend the service life of the halogen lamps.
"prop1- prop 5" These levels allow adapting the Scoro units to the proportionality of
other broncolor power packs.
Note: If a power pack is used with less power, it is known that the halogen
modelling light is relatively weak and yellowish. To solve this problem, all
broncolor power packs may be operated with higher modelling light
proportionality.
Attention: The Scoro software automatically indicates in the LCD selection text the
possible proportionality levels, and warns of sudden altered power settings
made by the user.
Important: The modelling lights of all the connected lamps are proportional when all the
power packs (independent of their output) have the same proportionality
level. This only applies when all the modelling lights have the same
wattage.
6.2 Reduced modelling light
To avoid overloading the mains supply (AC-line), the 100 - 120 V versions of the power
packs reduce the modelling light intensity during charging. You can clear this factory-
installed feature if the power rating of the mains supply (AC-line) is sufficient - see
setting possibilities of the dimmer in section 11.11. When working on poor-quality mains
supplies (AC-line) you can also slow down the charging rate with the additional function
“charge time” – this reduces the risk of blowing the supply fuses (section 11.10).
During fast charging of Scoro A2S and A4S, the modelling light is dimmed, with the
exception of the lamp with the highest power, to avoid overloading the mains supply,
even when no reduction/ dimmer was set (section 11.11).

13
6.3 Modelling light switch on lamp
The switch on the lamp is used to switch the modelling light on and off. To avoid damage
to the lamp filament, always switch off the modelling light before moving the lamp.
7. Release
7.1 RFS interface (Radio Frequency System)
As a standard feature, Scoro power packs are supplied with a built-in RFS system. The
antenna is not visible as it is integrated into the handle. RFS can be switched on or off
with the key “ir/rf“ (14). A flash release is activated via RFS and ir by default. The
definition of the IR/RF key is entered in the LCD display under the position “infrared /
RFS“. The following settings are possible: IR/-, -/RFS, IR/RFS. See LCD setting function
“IR/ RFS channel“ (section 11.12).
For flash triggering via RFS, the channel (studio address) must correspond with the
channel of the RFS transmitter. The definition of the channel (studio address) is entered
in the LCD display under the position “Studio address“ (section 11.14). If the power pack
is triggered via RFS, flash triggering follows with a minimal time delay of approximately
1/1200 s.
7.2 Flash triggering via infrared receiver (ir)
The IR receiver can be switched on or off with the key “ir/rf” (14). If the function is
activated, the blue LED next to the key lights up. A flash release is activated via RFS and
ir by default.
The definition of the IR/RF key is entered in the LCD display under “IR/RFS channel“.
The following settings are possible: IR/-, -/RFS, IR/RFS. See LCD setting function “IR/
RFS channel“ (section 11.12).
Scoro power packs may be triggered by broncolor infrared transmitters. If the power pack
is triggered via infrared, the flash release follows with a minimal time delay of
approximately 1/2000 s.
7.3 Photocell (cell)
The photocell can be switched on or off using the "cell" key (13). If it is activated, the blue
LED next to the key lights up.
After the first flash of a sequence, the active photocell will be blocked and the blue info-
LED next to the “cell“ key (13) blinks. By pressing the "cell" key the cell is reactivated.
7.4 Sync socket (4)
The synchronous cables art. no. 34.111.00 and 34.112.00 may be plugged into the
socket to trigger flashes via cable.

14
7.5 "test" key (16)
This key (16) allows manual release of the power pack as soon as 70 % of the set
energy is available.
7.6 Servor d
Please note: when you are working in the studio with the remote control Servor d,
unintentional and uncontrolled flash triggering by the Scoro power packs could occur. In
this case, please switch off the “IR” function (see section 11.12).
8. Remote control
The remote control system has 15 channels (studio addresses) and 15 unit addresses.
The channels divide the studio into different workstations of up to 15 flash units. Each
flash unit within a workstation is identifiable by its own unit address. Every other
workstation can each operate up to 15 flash units. Therefore, flash units of multiple
workstations are clearly identifiable. A PC or Macintosh computer, or an RFS transmitter
can control all the flash units of a studio workstation (channels/studio address).

15
8.1 Computer connection with RFS (Radio Frequency System)
All Scoro A power packs have a built in interface which allows remote control or flash
triggering of the power pack via radio from RFS transmitter, as well as RFS transceiver
from PC or Macintosh computer. Therefore all the Scoro power pack functions can be
comfortably controlled from a digital workstation.
8.2 Remote control channels (RFS studio address)
Remote control by means of RFS may be performed via separate channels (studio
workstations). These can be set in the LCD-menu under “Studio address“ (see section
11.14). All flash units within a studio workstation must have the same channel number
(studio address).

16
8.3 RFS unit addresses
Unit addresses will be assigned to each power pack for individual control. (See section
11.15).
8.4 Computer connection with cable
Scoro units are equipped with a computer connection socket (3). This allows operation of
the power pack from the computer via cable. Each channel can control up to 15 units.
Hence, Scoro power packs can be remotely controlled by cable with the Bron studio
9. Displays visual/audible
9.1 The visual ready signal
This is the blue LED at the “test” key or ready display (16). It lights up only when the unit
is fully charged or discharged. After triggering a flash, this LED goes out, and lights up
again when the unit is fully charged once more.
The visual ready signal is easy to read even from larger distances. The brightness can be
altered by the user (high & low) (see section 11.17).
9.2 The audible ready signal
An acoustic signal (beep) sounds when the power capacitors are 100 % charged, or
discharged. The signal may be switched on or off, and the volume may be regulated. The
corresponding setting options are explained in section 11.18.
When Scoro power packs are assigned an individual address, the acoustic signal can be
programmed with an individual acoustic (beep) tone. The tone is different for each power
pack address.
9.3 Visual fault signal
In case of technical faults or a signal from the flash-monitoring, the test release button /
the ready signal (16) will light up red.
9.4 Audible fault signal
When the flash discharge fails, a warning signal (two-sound tone) of approx. 0.5 s
duration will sound and the display (11) of the relevant lamp will flash.
9.5 Audible messages
Clicking tone:
- Keys sound (setting of volume is explained in section 11.19).
„Beep“ tone:
- End of charging or discharging (setting of volume is explained in section 11.18).

17
“Double-beep” tone:
- Energy limit top or bottom when controlling energy via RFS transmitter
- Reset key pressed for 2 s (resetting of additional functions)
- Reset key pressed for 10 s (reset to factory settings)
“Two-sound” tone:
- Technical fault. Ready signal (16) lights red.
- Flash monitoring. The display of the lamp which has not fired lights up.
- Beginning and end of a thermal blocking procedure. Display in LCD.
- A suggestion appears on the LCD when setting changes are not possible with
the previous specifications.
10. Special functions
10.1 Speed key (17)
When the speed key is activated, the corresponding LED lights blue and the maximum
flash energy of A2 models is reduced from 1600 J to 1200 J, and the energy of A4
models is reduced from 3200 J to 2400 J. The flash duration t0.1 is also reduced. In
speed operation, the optimum colour temperature is fractionally colder, however,
consistent over the energy adjustment range.
10.2 Energy display
- By default, the power display indicates the residual flash energy resulting from the
decrease of the maximum flash energy. The maximum power indicated in the master
power display (12) of the Scoro A2 and A2S can be reduced from 10 to 9.0 (see LCD
function “Max.display”, section 11.22). Therefore, with the same set energy of a Scoro A4
or A4S or of another 3200 J flash unit, an identical value will be displayed.
- In speed mode, the maximum power indicated in the master power display (12) can be
increased from 9.6 to 10 (see LCD function “Max. display”, section 11.22). Should the
maximum power indicated in the master power display be reduced from 10 to 9.0 (see
above, first paragraph), then in speed mode, because of the direct association, the
display will be increased from 8.6 to 9.0.
10.3 User key (18) and memory function
When the user key is „on“ it activates the initial settings of a further operator. With this,
Scoro A power packs can be individually configured for two or more users in which all the
relevant functions and settings are separately stored, thus providing independent
preference capabilities for multiple users.
In normal and user mode, there are each four own memories available. All the unit
settings can be stored therein (see LCD function “memory 1-4” section 11.21). Selecting
one of the four memories redirects to an information window in the LCD, in which the
most important data of the corresponding memory are indicated. Pressing the “recall” soft
button reinitializes the data in the memory. Pressing the “store” soft button overwrites the
memory contents with the latest unit settings.

18
10.4 Reset key (19)
- Brief pressure on the reset key advances the cursor directly to the main page. When
pressing the menu key (22) the cursor returns to the beginning of the main menu.
- Pressing this key for approximately 2 s reinitializes the (visual) additional functions
which are listed in the display. An acoustic sound (double-beep tone) confirms the
resetting of the values.
- Pressing this key for approximately 10 s resets all the functions to the factory settings.
An acoustic sound (double-beep tone) confirms the resetting of the values.
